Vol. XXXVIII. THE OCCURRENCE OF THE GENUS CRYPTOZOON IN THE (2) CAMBRIAN OF AUSTRALIA. By Watter Howcuin, F.G.S., Lecturer in Geology and Paleontology, University of Adelaide. [Read April 2, 1914. ] Piates I. to V. A few months ago Mr. Charles Chewings, Ph.D., for- warded to me from Central Australia a few specimens of a fossiliferous limestone which he thought might be of interest. The organic remains in the limestone being, for the most part, less soluble than the matrix, had weathered into strong relief and thereby exposed both the outline and structure of the fossils in a way very favourable for observation. The very striking resemblance which these forms bore to the obscure fossil, long known to American geologists from the lower Paleozoic rocks as Cryptozoén, was at once apparent. Photographs were taken of several of the specimens and forwarded to Dr. Charles Walcott, the Secretary of the Smith- sonian Institution (who has an intimate knowledge of Cam- brian paleontology), for his opinion. Dr. Walcott confirmed the determination that the objects belonged to the genus re- ferred to, and passed the photographs on to Mr. Bassler, the Curator of Palzontology in the United States National Museum. Mr. Bassler, in a communication which he kindly favoured me with on the subject, says: “Your photographs represent undoubtedly a new species distinguished from all the other known forms by the fact that the ‘heads’ are separate and column-like instead of confluent as in most of the other 2 species. New species similar to this one are known in the lowest Ordovician (Beekmantown) formations of the United States, and it is barely possible that, on account of the similarity, your specimens are from the same horizon.”’ The genus (Cryptozoén) was established by Professor James Hall, in 1884.0) MHall’s description has been quoted, an extenso, by Dr. Walcott.) As the literature on the sub- jects is limited and not very accessible, it may be found useful to reproduce Hall’s description here : — “In the town of Greenfield, Saratoga County, there occurs a bed of limestone which presents a very remarkable appear- ance, the surface being nearly covered by closely arranged circular or sub-circular discs which are made up of concentric laminz, closely resembling in general aspect the structure of Stromatopora. It very often happens that within these larger discs there occur two or more smaller ones, each with its own concentric structure and exterior limitation, and appearing as if budding from the parent mass. A farther examination shows that the entire form of these masses is hemispheric or turbinate, with the broadest face exposed upon the upper surface of the limestone layer; that their growth has begun from a point below, and, rapidly expanding upwards, has often extended one or two feet in diameter, as now shown upon the exposed surface of the limestone bed. At a single exposure on the farm of Mr. Hoyt, the surface of the limestone is covered by these bodies for many rods in extent. The entire area of the cellar beneath the house of Mr. Hoyt is upon this bed of limestone closely covered by these hemispheric masses with concentric structure. For a distance of one or two miles to the southward the outcrop of the limestone can be traced, and everywhere presenting the same characters in the presence of these masses. Large numbers of specimens of various sizes have been weathered out and lie scattered over the surface. This fossil has also been found at Little Falls, Herkimer County, New York. “These bodies have long been known under the name of Stromatopora, from their general resemblance in form and structure to that fossil; but their position in reference to the bedding of the rock is uniformly the reverse of that. of Stromatopore, which occur in the higher limestones, growing from a broad base which is covered by an epitheca, while these bodies under consideration grow upward and expand _ (@)Thirty-sixth Ann. Rept. New York State Mus. Nat. Hist., description of pl. vi. _(2)Smithsonian Miscell. Coll., vol. lvii., No. 9. Jdem, pl. xxxvil., photo. of C. proliferum, by Dr. Walcott. 3 from a point below, while the convex surface is on the lower side. A careful examination of the nature of these bodies proves that, while having the concentric structure common to Stromatopora, they have not the regular succession of layers of tubuli characteristic of the species of that genus and cannot properly be included under that term. I therefore propose the term Cryptozoén as a designation for this peculiar form and mode of growth which will be more fully elucidated in the future.” Hall recognized but one species (Cryptozoén proliferum), which he defined in the following terms : — “These bodies are made up of irregular, concentric laminz of greater or less density and of very unequal thick- ness. The substance between the concentric lines, in well- preserved specimens, is traversed by numerous, minute, ir- regular canaliculi which branch and anastomose without regularity. The central portion of the masses are usually filled with crystalline, granular, and oolitic material, and many specimens show the intrusion of these extraneous and inorganic substances between the concentric lamine. That these are intrusions and not inclusions, is shown from the fact that they can be traced to a vertical fissure or break leading to the exterior of the fossil, and which allowed the crystalline matter to enter.” Sir William Dawson examined specimens from the type locality and has published () the following additional observ- ations : — | “Thin slices, from specimens kindly presented to the Peter Redpath Museum by Professor Hall, show that the primary lamine are thin and apparently carbonaceous, as if originally of a corneous or membranous character, and they are usually finely crumpled as if by lateral pressure, while they can occasionally be seen to divide into two laminze with intervening coarsely cellular structure. The thick intermediate layers which separate these primary laminze are composed of grains of calcareous, dolomitic, and siliceous matter, in some specimens with much fine carbonaceous material. This last, under a high power in thin slices, is seen to present the appearance of a fine network or stroma in which the inorganic particles are entangled. The canals traversing these inter- mediate layers appear to be mere perforations without distinct walls, and are filled with transparent, calcareous matter, which renders them, under a proper light, sufficiently distinct (3) Note on Cryptozoén and other Ancient Fossils. Canadian Record of Science, vol. vii., No. 4 (October, 1896), p. 205. B2 4 from the grey granular intermediate matter which they tra- verse. So far as observed, the canals are confined to the inter- mediate layers, and do not seem to penetrate the primary lamine, though these sometimes present a reticulated appear- ance, and seem to have occasional spaces in them which may have been communicating pores or orifices.”’ In the same paper from which the above descriptions have been taken, Dawson describes two additional species : —(@) Cryptozoén boreale.—‘‘Consists of a mass of cylindrical or turbinate branches, proceeding from a centre and also budding laterally from each other. Each branch shows a series of laminz concave upward. The spaces between the thin laminz are filled with a very fine granular material in which are canals, less frequent, straighter, and more nearly parallel to the lamine than in the typical species. This species is remarkable for the slender and coral-like shape of its branches.”’ The specimens were obtained at Lake St. John, Quebec, in rocks of Trenton (Ordovician) age. Cryptozoén occidentale.—This species was described from imperfectly preserved specimens obtained from the Grand Canyon, in Arizona, and from rocks which have been classed as “Pre-Cambrian”’ (corresponding to the Kewenian of Lake Superior, and the Etcheminian of southern New Brunswick), and therefore belonging to the lowest known fossiliferous horizon. Dr. Dawson says: “Though most of them were im- perfectly preserved, one of them exhibited the concentric laminz of Cryptozoén, and the intermediate layers composed of microscopic grains which were ascertained by Dr. Adams to be partly siliceous and partly calcareous (dolomite and calcite). Instead of the irregular curving canals of the typical Cryptozodn, where best preserved they show ragged cells, giving off on all sides numerous small tortuous and branching canals, but their structure I regard as possibly corresponding to that of Cryptozoén, and I would therefore venture to name the species C. occidentale in hope of the discovery of better specimens. ’’ Two other doubtful determinations may be mentioned on the authority of Dr. Dawson.(5) In 1885, Professor N. H. Winchill named a Stromatopora-like form C. minnesotense, from the Upper Cambrian of Minnesota; and Dr. Dawson named another form from the Calciferous (Lower Ordovician) of Lachute, Province of Quebec, but the author states: “I can- not positively affirm that this is a distinct species, but may provisionally name it, C. lachutense.”’ (4) Loc. cit., pp.’ 207 and 208, figs. 1-3.

Matthew from the Pre-Cambrian limestones of St. John, New Bruns- wick, Canada, and named by him Archeozodn acadiense,® ap- pear to be the same, or very similar, organism as Hall’s Crypto- zoén, the chief difference being that while in Cryptozoén the laminz are concave to the direction of growth, in Arch@ozoén they are convex. This, however, may be of slight morpho- logical importance, and may indicate a difference of not more than specific value, if even it be that. The zoological position of this ancient organism is 1ill- defined and cannot, at present, be satisfactorily determined. In the first instance, and for some time after their discovery, they were regarded as Stromatoporoid in their affinities with probable relationships with the Hydrozoa. Later, when the microscopical structure was investigated, Dawson was led to believe that they were more nearly related to the Rhizopodal Protozoa. He says: “If we endeavour in imagination to restore these curious organisms, the task is a very difficult one. They, no doubt, grew on the sea-bottom, and must have had great powers of assimilation and increase in bulk. Still, it must be borne in mind that they were largely made up of inorganic particles collected from the mud and fine sand in process of deposition. The amount of actual organic matter in the hard parts, even of large specimens, is not very great, and the soft living material, if they were animal, must have been confined to the canals and to the exterior surfaces. ‘““As the only marine animals known to accumulate foreign matter in this manner are the Protozoa of the Rhizopod type, one naturally turns to them for analogies, and perhaps species of the genus Loftusia most nearly resemble them in general arrangement.” (7) When Dawson gave these descriptions the relatively large organisms, Loftusia and Parkeria, as well as the much-dis- cussed Hozoén, were regarded as Foraminifera. Since then, the first two mentioned have been classed with the Hydrozoa, and the third has been relegated to the inorganic world. Cryptozoén is of gigantic size, even when compared with the largest of all known Foraminifera, and its internal struc- ture is by no means conclusive of a relationship to these or any other section of the Protozoa. The large proportion which the mineral constituents bear to the whole structure is sug- gestive of an animal rather than a vegetable origin, although (6)G. F. Matthew, Presid. Add. Nat. His. Soc. of New Bruns- wick, Bull. ix., p. 32 (1891) also, same author, Note on Arche@ozoén, age oul xxv. (vol. v.), p. 547 (1906). Sir W. Dawson, loc. cit., 2. ’ . (Loc, cit., p. 209. 6 the possibility of their being related to the calcareous Alge must be considered. The testaceous Protozoa are not pro- minently developed in the lower. Paleozoic rocks, and when they do occur are, mostly, inconspicuous. On the other hand, Cryptozoén reached, relatively, gigantic proportions. Dawson says: “The larger masses are from one to two feet in diameter.’” It seems probable that Cryptozoén is a primitive type that does not closely accord with any of our existing phyla, but may be an ancestral form of the Stromatoporoidea, or some other group of the calcareous Hydrozoa. The silicification of the fossils is undoubtedly pseudomorphic in its origin. They were, no doubt, originally calcareous, and in the case of one species, described in this paper, the silicification is present only to a very limited degree. In dealing with so ancient an organism of doubtful affinities it is difficult to determine what particular features are of specific value. The Australian specimens exhibit a close re- semblance to the generic type, but appear to be distinguish- able from all hitherto described species in some particulars. CRYPTOZOON AUSTRALICUM, sp. nov. Plates i. and ii. Skeleton consists of columnar growths which, in transverse sections, are circular or sub-circular. Average diameter of columns, # in.; with a range of variation from i in. to 2 in. in diameter. No peripheral wall. Each column is built up of closely-set lamine, of varying thickness, which are either concave or convex to the direction of growth.) The lamine are situated about one millimetre apart (about 25 laminz to the inch), and are sometimes crenulated or wavy. The laminz, which in the fossil condition comprise the entire skeleton, consist of earthy or siliceous material which is not acted upon by acids, and under a magnifying lens exhibits a very minute labyrinthic or spongiform structure. The spaces between the lamine are filled with a fine, granular, calcareous material identical with the rock mass in which the fossils are embedded. As a rule the columns are separate and exhibit a regular parallelism of growth. (8) The fragmentary condition of the specimens make this point somewhat uncertain, as it is at times difficult to. determine which is the right way up of the columns. It is assumed, however, that the thicker end of the column is the growing end, and, on this evidence, where it is available, it would appear that the laminze may take either an upward or downward curve, or be flat in the centre and then turned either upwards or downwards when approaching the periphery of the column. These variations may prove to be only accidents of growth. 7 The relative insolubility of the fossils, in ‘comparison with the matrix, has led to their weathering out in strong relief. It is highly probable that the original skeleton of the organism was calcareous, and that the present form is that of a siliceous pseudomorph, in a similar way that many of the Archwocya- thine, in the Cambrian of South Australia, are preserved in the form of siliceous casts. The interlaminar spaces, now filled with the rock matrix, may possibly represent the chambers that contained the protoplasmic material of the living organ- ism; or, otherwise, some portions of the skeleton that failed to fossilize. The present species differs from the type (C. proliferum, Hall) in the greater independence of the columns, and also in their more regular arrangement. CRYPTOZOON TESSELLATUM, sp. nov. Plates 111. and iv. Among the specimens sent down by Dr. Chewings are three which possess features somewhat different from those just described. In this form the columns are almost en- tirely calcareous, and vary greatly both as to size and shape. In transverse sections they may be circular, sub-circular, quadrate, angular, or irregular in form, and are frequently confluent and branching. Notwithstanding their great di- versity of shape they maintain a very regular arrangement in relation to each other, the intercolumnar spaces being uniform throughout. This form of growth, together with the fact that the fossils and the limestone matrix weather uni- formly, gives a curious tessellated or mosaic appearance to the specimens. So far as can be determined from the limited material at command the laminz of the columns are similar to those described in the preceding species. The distinctive features in the present species are the irregular shape of the columns, their frequent bifurcation and confluence, and the regularity of the intercolumuar space. As all the spcimens at command are fragments, it is im- possible to determine what may have been the shape of the “organism in its aggregate or compound form. LoOcALITY AND MoprE oF OCCURRENCE. The locality where Dr. Chewings discovered the fossils described in this paper was near the eastern end of the South ‘MacDonnell Ranges, on the north side of the mail road from Alice Springs to Arltunga, midway between Mount Benstead and Love’s Creek station. In relation to the discovery, Dr. Chewings writes from Arltunga (September 12, 1912): “You will be interested to know that I made what I take to be a very important dis- covery of probably Cambrian fossils the other day, in the MacDonnell Ranges. They occur for several miles in a massive limestone (dolomite) range that skirts the gneissic and granitic formation of the Central MacDonnell.” The following is a sketch supplied by Dr. Chewings to show the stratigraphical relationship of his discovery to the fossiiferous Ordovicians of the same ranges : — SKETCH SECTION OF CENTRAL MACDONNELL RANGES (Chewings). A. Gneissic and Granitic (? Pre-Cambrian). © B. Quartzite (? Cambrian). C. Dolomitic Limestone (? Cambrian); Cryptozoén fossils at x x. D. Ordovician fossils at xx. “The Ordovician beds (D), with fossils, occur as shown on the rough section. The ‘inner’ quartzite and limestone beds (B and C) I have always held to be older, but could never find fossils in them until now.”—[Chewings. | In a further letter, dated October 5, 1912, from Charlotte Waters, he writes: “The quartzite runs the whole length of the MacDonnell Ranges, vzz., from beyond Mount Udor to east of Arltunga, sometimes in broken and isolated hills, at others in a continuous line or lines forming the highest range of the MacDonnell. The dolomite I know to extend from Mount Giles to east of Arltunga, and, lke the quartzite, is always very much disturbed, broken, and thrust about. It has undergone such disturbance and aiteration that all trace of fossils has, in most parts, disappeared. Where the fossils were found the dolomite is of great thickness, and for a couple of miles, in one place, viz., near Acacia Well, which hes south of Mount Benstead, and in another, viz., two miles south of Bitter Springs, the fossils escaped obliteration. The two spots are five miles apart. Where the samples were found there is no lack of similar material, the rock being largely composed of the same coralline rock, or what origin- ally were corals. Where the fossils occur the dolomite beds moO 9 DE dip south, at say, 3: 9 GEOLOGICAL AGE OF THE FOSSILS. Unfortunately there is a want of agreement in the opinion of the few geologists who have had the opportunity of examining the older rocks of Central Australia. Mr. H. ¥G L. Brown, the late Government Geologist, as well as Dr. Chewings,0) include a Cambrian series between the Pre- Cambrian and the Ordovician of the MacDonnell Ranges; whilst Tate and Watt do not recognize any rocks of Cambrian age in the MacDonnell Ranges, and affirm that the Ordovicians rest directly on the Pre-Cambrian bed-rock. This interpre- tation of the geological order is strongly maintained by these authors (in opposition to the views of Brown and Chewings) in their Report of the Horn Expedition to Central Australia. It is in this disputed borderland, between the Ordovician and Pre-Cambrian, that Dr. Chewings obtained the fossils described in this paper. Tate and Watt would probably in- clude the fossiliferous horizon in their Ordovician, while Brown and Chewings place it in the Cambrian. As bearing on this question it is important to note that undoubted Cam- brian fossils have been found in Central Australia. An Olenellus (O. browni) was obtained by Mr. Brown at Alex- andra station, situated between Tennant Creek and the Queensland border; and Agnostus and Microdiscus were ob- tained at Elkedra station, 150 miles south of the preceding locality, and in a north-east direction from the MacDonnell Ranges. In America the genus Cryptozoén appears to have a rather extensive vertical range—Etcheminian, Cambrian, and Lower Ordovician. It is, therefore, of little value in the present case for determining the geological horizon. The matrix of the Cryptozoén fossils in the MacDonnell’s does not, however, resemble the typical limestone of the Ordovicians of that region. The latter are “grey, yellow, and red,’ while the Cryptozoén limestones are of a bluish tint and granular structure, having a marked similarity to many of the mag- nesian limestones of the Cambrian of the Flinders Ranges, more to the south. The question of age must be left as a doubtful point at present, with the weight of the evidence, probably, in favour of them being Cambrian. (9)Mr. Brown’s views are contained in various official reports, published by Authority, and also in his Geological Maps of the MacDonnell and associated regions.

By Eustace W. Fereuson, M.B., Ch.M. [Read April 2, 1914. ] Some little time ago, on requesting permission to examine the A mycterides in the South Australian Museum, the authori- ties of that institution very kindly allowed me full oppor- tunity to examine all the specimens in their charge and to describe the new species. The present paper deals with the first four principal genera, together with one or two smaller allied ones. I have thought it advisable to note all the species sent for examination, together with their habitat. In this connection it should be noted that many of the older speci- mens are without locality labels beyond ‘‘Australia. Old collection.’”’ The collection is particularly rich in species of Sclerorimus, but I have purposely deferred commenting on the range and distribution of these until the genus is con- sidered as a whole in the revision of the subfamily at present being published in the Proceedings of the Linnean Society of New South Wales. The descriptions of the new species are given at the end of the paper. 1. Psalidura reticulata, Boisd.—New South Wales: Sydney. 2. Psalidura cox1, Macl. P. coxi, Macl., var. A.—New South Wales: Tam- worth. 3. Psalidura costipennis, Ferg.—Queensland: Mount Tambourine (A. M. Lea). Four specimens, two of each sex, agreeing with type except that coste are perhaps slightly less prominent, and the sete are more numerous. 4. Psalidura miracula, Macl.—New South Wales: Blue Mountains, Tenterfield. | 5. Psalidura approzimata, Ferg. — Victoria: Mount Buffalo (Blackburn). 6. Psalidura forficulata, Macl.—South Australia: Ar- drossan (Tepper). I can detect no difference between Queensland specimens and this single South Aus- tralian example. It would be interesting to know if the species occurs elsewhere in South Australia; otherwise, if this locality be correct, it is very diffi- cult to account for its occurrence so far south. 10. 1g 6 12. 1}. 14. 12 . Psalidura frenchi, Ferg. (?)—Queensland: Hughenden (A. M. Lea). <A single 3, probably this species, but with somewhat different elytral sculpture. . Psalidura grandis, Ferg.—South Australia: Leigh Creek (Blackburn), Muloolas. . Psalidura caudata, Macl.—Queensland (Blackburn), Longreach (A. M. Lea). Psalidura flavosetosa, Ferg.—South Australia: Ouldea, Fowler Bay. Also from mallee districts, Victoria. Examination of a number of fresh speci- mens shows that the type has suffered some damage, probably from Anthrenus. 'The posterior edge of the anal segment is fringed with long hair or sete, a similar tuft is present on the interforficular process of the apical dorsal segment; the laminz also are not absolutely linear, but are narrow, with gently rounded edge, and can only be clearly seen from behind. It should probably be placed in the caudata group, from the two other species of which the widely separated fascicles will distinguish it. The colour of the setz is variable, and the name is hence not a good one. Psalidura elongata, Macl.—New South Wales: Con- dobolin. Psalidura flavovaria, Ferg.—South Australia. Doubt- fully recorded from South Australia; the Museum specimens confirm this habitat. It also occurs in Victoria, specimens having been shown me from Mount Macedon and Portland. Psalidura squamigera, Macl.—New South Wales: Tamworth. Psalidura mirabunda, Gyll.—Tasmania; Victoria. Several specimens sent under the synonyms impressa and howittr. A Q labelled ““Billinghurst’’ appears to belong to the same species. It is highly probable that mirabunda, Gyll., will have to be sunk in favour of mirabilis, Kirby. EHrichson (Wiegm. Arch. 1., 1842, p. 113) definitely says that the two names belong to the one species. Specimens of mirabunda and reticulata were sent to the British Museum for comparison with the type of P. mirabilis, but unfor- tunately it could not be found. Kirby describes the lamine as “‘latz, compresse, obcuneatze, apice rotundate, levissime, glaberrime, nitide,’’ a description which, of all the species known to me, will only accurately fit mirabunda. 23. 24. 25. 26. 27. ae. 13 .

Specimens from Port Lincoln (Blackburn) differ in being smaller and in having rather more regular elytral granules.

Talaurinus STR OOS, Macl.—New South Wales: Mulwala. Talaurinus wnconspicwus, Ferg. Talaurinus strangulatus, Blackb.—Central Australia: Oodnadatta (co-type). An obscure species which I cannot refer with any certainty to any of my groups; probably it is most nearly allied to the squwamosus _ group, though its elytral structure is at variance with the members of the group. In the present: state of our knowledge of this difficult section (granulati) any arrangement into groups can only be considered as provisional, and isolated species from little-known regions are best left with merely an indication of their apparent affinities. Talaurinus, sp.—South Australia: Lake Callabonna (Zietz). A single Q resembling Z'. strangulatus, (1) Not T. carbonarius. A specimen has been compared with the type of T. carbonarius by Mr. K. G. Blair, of the British Museum, 42. 43. 44, 45. 46. 47. 15 but with different clothing and arrangement of granules, also showing an approach to 7’. squamosus. I hesitate to describe on a single Q. Talaurinus angularis, Ferg.—New South Wales: Tamworth (Musson). Talaurinus scapularis, Ferg.—Queensland. Talaurinus ambiguus, Macl.—No locality. Talaurinus prypnoides, Ferg.—South Australia: Mount Lofty (Tepper). Talaurinus imitator, Blackb.—Central Australia (co- type). Talaurimus crassiceps, Sloane, type.—Central Aus- tralia: Barrow Range. In my table of the genus this species would be associated with 7. imitator in Group VI. The two species may be conveniently separated as follows :— Group VI. d. Intrastrial granules prominent, the de- pressions reduced to transverse fur- rows Pelee eee etn iuancor.. Blackbe dd. Intrastrial ridges not granulate, the de- pressions subquad- rate, foveiform ...

Talaurinus helmsi, Sloane species are before me, . Talaurinus equalis, Sloane (together with an ex- . Talaurimus solidus, Sloane tensive series of speci- mens from the Elder Expedition collected by Mr. R. Helms. In this connection it might be said that Mr. Sloane in describing these species had only two specimens of each sent to him, and therefore was not- in a position to judge correctly of their variation. The species were separated upon differences in con- vexity, in the degree of dilatation of the elytra, in the regularity of the sculpture, and in the granules. In all these points, however, the differences are slight and often elusive, and indeed appear to be incon- stant. After careful examination of a large series I am now of the opinion that all the forms are refer- able to one variable species, though it may be advis- able to recognize some of the names as worthy of subspecific rank, 16 T’. regularis, as the species first described, must retain its name; it is characterized by the regu- larity of its elytral sculpture, the granules on the second and fourth interstices being small and hardly larger than those on the other interstices, the number of granules on the second is only a few less than the number on the third interstice. T. helmsi was separated on account of its nar- rower form, greater convexity, and the less conical granules of the elytra. The differences are, how- ever, slight and inconstant, and I regard 7. helmsi as certainly conspecific with 7. regularis. T. equalrs differs in its flatter form and in the granules on the second and fourth interstices, these are fewer in number, more elongate and more depressed; the relation of the granules on the second to those on the third interstice is about one to two. It would seem advisable, therefore, to retain the name e@qualis at least for a variety. The above notes are founded on an examination and comparison of the ¢ types of the species. On the females.it is not so easy to reach a conclu- sion, the sculpture of the elytra varies more and in all the females are more robust and convex; indeed, it is not easy to absolutely associate females with the corresponding males. The type females of T. regularis and T.. equalis are in my own col- lection, having been retained by Mr. Sloane, so I have taken them for comparison. The types (Q) of T. regularis and of T’. helmsz correspond fairly closely with their respective males; the Q type of T. equalis, however, while of the elongate depressed form of the ¢, has the elytral inter- stices much more evenly granulate, and corresponds more with a number of specimens in the Museum collection. from North-west South Australia (Wells’ Expedition). The type of 7. solidus is a @, and in size and general appearance closely resembles the Q 7. regularis; it, however, has the granules larger and fewer in number on the second and fourth interstices. JI am inclined to regard the type as a large specimen of 7’. equalis. In conclusion I may say that the slight differences between 7. regularis and T. equalis are much less than exist in big series of other species, as for instance in T. bucephalus, and I think there is little to be iy. gained in maintaining them as distinct species. I may add that Mr. Sloane very kindly re-examined his types and the other specimens while on a recent visit to Sydney, and was of the opinion that the specimens were all one variable species with the pos- sible exception of the Q type of T. e@qualis, which has in addition to other slight differences a slightly different impression on the fifth ventral segment. | Hab.—Western South Australia, most of the specimens labelled ‘‘Elder Expl.

Sclerorinus waterhouser, Macl.—South Australia ; Central Australia. Two <’s without exact locality labels. Sclerorinus adelaide, Macl.—Australia, no locality. A specimen which I regard as only a form of this: exceedingly variable species. Sclerorinus vittatus, Macl.—Ardrossan; South Aus- tralia (Tepper). Specimens from South Australia, without locality, and from Ardrossan agree with the type in form and appearance, but exhibit, inter se, great variability in the number, size, and position of the elytral tubercles. Specimens from Grange, South Australia, agree fairly well with both the types of wittatus and conspersus, and I see little reason for separating the two species beyond a slight. difference in shape and the somewhat smaller tubercles. S. rugicollis and S. angasi are, In my opinion, undoubtedly conspecific with S. vittatus. Sclerorinus, sp. (?)—A single ¢ allied to wittatus, and perhaps only an extreme variety. In the absence of further specimens, it would be unwise to deal with it at greater length at present. Australia, no locality. Sclerorinus sordidus, Macl.—South Australia: Victor Harbour, Adelaide, Mount Lofty. Others without. exact locality. A fairly large series of specimens, which I regard as referable to this species. The species 1s close to S. wittatus, but has more dingy clothing and less prominent tubercles concealed by the clothing; in these respects, however, the series shows considerable variation, this being more marked. oo, 80. il: 82. 83. 84, 85. 86. 37, 88. 89. 90. 19 in the females, which are, as a rule, larger and more coarsely tuberculate than the males. As with most _ of the other species of the adelaide group, the species shows a tendency to merge with the species above and below it in the scale of magnitude and tubercular development. While some specimens show a decided approach to S. wittatws, others are hardly separable from the following species, and there are intermediate forms. Sclerorinus acuwminatus, Macl.—South Australia. Specimens compared with type of acuminatus agree also fairly closely with specimens of sordidus, except that they are smaller and have rather smaller tubercles. The fifth interstice is practically obsolete, while in sordidus it is as a rule fairly definite, though some specimens show a tendency towards obliteration. Sclerorinus tristis, Boisd.—Tasmania. Specimens of a Sclerorinus from Tasmania without doubt belong to this species. Sclerorimus asper, Macl.—South Australia. Specimens from South Australia agree with the type. Sclerorinus howitti, Macl. — Victoria. A Q from Victoria agrees with the type. It is very doubtful if S. asper and S. howitte can be maintained as dis- tinct from S. tristes; I myself do not think that they can. S. acuminatus and S. obliteratus are also ex- tremely doubtfully distinct, though there seems more justification for their separation. Sclerorinus obliteratus, Macl. (?)—Australia. A o without locality agrees fairly closely with the type, which is, however, a Q. Sclerorinus, sp.—Victoria: Mount Buffalo. Close to S. obliteratus, but possibly distinct; both specimens are, however, males. Sclerorinus, sp.(?)—A od from Aldgate probably represents a new species of this group. Sclerorinus, sp.(?)—A <¢ from Ballarat has the sculpture almost obliterated; it is possibly distinct. Sclerorinus, sp. (?)—Victoria: Nelson (Blackburn). Close to S. obliteratus, Macl., but probably distinct. Sclerorinus wrregularis, Macl.—South Australia: Square Waterhole. A single Q, in general appear- ance closely resembling S. sordidus. Sclerorinus, sp.(?)—Kangaroo Island. A_ single Q greatly abraded, but apparently belonging to an undescribed species allied to 8. sordidus. Sclerorinus neglectus, n. sp. 20 91. Sclerorinus regularis, n. sp. 92. Sclerorinus convexus, Sloane, var. spenceri, n. var.— Among the specimens sent were a number which show some variation, inter se, and which all differ from the type of S. convexus in my own collection. I can not regard these specimens as belonging to more than one species, though as the only specimen I have seen of S. convexus is the type, I cannot be certain if they represent a distinct species or only a variety ; apparently this is the species that Blackburn (Report Horn Exped.) recorded as S. convexus. Under the circumstances, I have thought it advisable to give a varietal name to these specimens, and have adopted the name which Blackburn had apparently originally (a specimen in my collection is labelled ‘‘spencerv”’ in Blackburn’s handwriting) given them in honour of Professor Baldwin Spencer. Below are given the chief characters for differentiating the variety from S. convexus :— 3. Larger than S. convexus, less parallel- sided; head and rostrum as in type; prothorax variable, in specimen selected for description granules somewhat larger than in convexus and somewhat abraded; elytra with nodules on inter- stices larger, more elongate, much fewer in number on the second and fourth, on the second ending suddenly at declivity not extending down as gradu- ally diminishing granules. Dim.— 6, 23x8mm.; 9, 22x8 mm. Hab.—Ouldea to Talarinna (R. T. Maurice), North-west South Austraha (Wells Exped., H. Basedow), Deering Creek (Horn Exped.), Her- mannsburg. None of the specimens show any signs of clothing, though such is evident in S. convezus. Two specimens differ in being larger, more con- vex, and with rather coarser nodules. I cannot regard them as specifically distinct. 93. Sclerorinus insignis, Sloane.—Type, Elder Exped. 94. Sclerorinus noctis, Sloane.—Type, Barrow Range, Elder Exped. I would refer these two species, originally placed in Talaurinus, to Sclerorinus; they are closely allied, but I believe distinct. How- ever, it is impossible to speak absolutely on this point, as they are of opposite sexes. 95. (2) Talaurinus obscurus, Sloane.—Type, Elder Exped. Though Sloane regarded this species as closely allied 21 to converus, insignis, and noctis, I am inclined to regard it as probably generically distinct. Unfor- tunately, only the Q is known. 96. Sclerorinus, sp.(?)—A_ single 9 from Menzies belonging to the convexus group; possibly it may prove to be the Q of S. insignis. 97. Sclerorinus elderi, Sloane.—Type 3, Everard Range, Elder Exped. Besides the type the collection con- tains a number of specimens from different localities. The species is variable in regard to size, number, and to a certain extent arrangement of the tubercles. In the type ¢ the median ventral vitta is of a very dark-brown, practically black, colour; in the type Q (in my own collection) the vitta is light- brown. In almost all the specimens I have seen, ranging over a vast extent of country, the ¢ has the vitta of a light reddish-brown colour. Specimens of this type are in the collection from Ouldea and Fowler’s Bay; except that the tubercles are some- what larger, I cannot detect any other difference from the type. Specimens (¢ and Q) from North-west South Australia (Wells Exped., March, 1903) differ somewhat in being rather depressed above, and in having the tubercles somewhat irregular and of a black colour. I cannot regard them as specifically distinct. Another 9 from Gawler Ranges also shows some slight differences in the tuberculation. The range of the species appears to extend from the western portion of South Australia as far as the Murchison district in Western Australia. 98. Sclerorinus molossus, Pasc.(?)—Three specimens which I refer with some doubt to this species. They differ from 8S. eldert in the smaller prothoracic tubercles and also somewhat in the elytral tubercles. The specimens are from (1) Coolgardie (Blackburn’s: collection), ¢; (2) Yorketown, 9; (3) Australia (Blackburn’s collection), no locality label, 9. Pos- sibly they do not all belong to the same species, but I have little doubt that they do so. 99. Sclerorinus angustipenms, Sloane. Type 3. A second 3 labelled ‘‘Frazer Range.’’ A Q labelled ‘‘Western Australia,’’ Blackburn’s collection, appears slightly different, though the differences are possibly sexual. The rostrum is rather stouter, the prothoracic granules less abraded, and the prothorax not so dilatate. 100. 101. 102. 03. 104. 4105, 106. LOT LOS: 109: 22 Sclerorinus occidentalis, Sloane. Types, ¢, 2. This species is very close to S. angustipennis, but I regard it as distinct. Two other specimens from Blackburn’s collection are in the Museum, and one (9) labelled ‘‘Upper Murchison, Helms’’ (the type locality). Sclerorinus, sp. n.—A ¢ labelled ‘‘Western Australia,’’ York, Blackburn’s collection, belongs to a new species allied to S. eldert. In the absence of more specimens I have not thought it advisable to describe the species. Sclerorinus molestus, Pascoe (?).—Eyre Sandpatch, Fowler Bay, Ouldea. An extensive series was sent of a species which I have had with some doubt iden- tified as S. molestus by Mr. Blair, of the British Museum. The species appears to be common in the regions bordering the Great Australian Bight, and is' recognizable by its parallel-sided form with dense yellowish clothing, except on the tubercles. Several specimens from Eyre Sandpatch differ from the usual form in having the prothorax more dilatate and the elytra not parallel-sided; the tubercles are also rather smaller.) I do not regard the form as specifically distinct. One ¢ labelled ‘“‘Fowler’s Bay”’ appears somewhat different, but is greatly abraded; the tubercles are red instead of black, diluted with red. Sclerorinus sabulosus, Macl.—South Australia: Port Augusta. Sclerorinus, sp. (?)—A single specimen from Pinnaroo of what is probably a new species allied to S. sabulosus. I have numerous specimens from the mallee districts of Victoria at present under examination. Sclerorinus biordinatus, Macl.—Yorke Peninsula. An exceptionally beautiful species. Sclerorinus blackburm, n. sp. Sclerorinus exis, Macl. Sclerorinus longus, Macl. Sclerorinus vestitus, Macl.—South Australia: Gawler Ranges; New South Wales: Silverton; Victoria: Birchip. The Victorian specimens are, as a rule, narrower than the South Australian, but I do not regard them as distinct. (3) Judging from notes forwarded by Mr. Blair, this form ‘probably corresponds closely with the type of S. molestus, Pasc. 110. Eee 212. 113. 114. 115. 116. Evy. 118. ISL 120. 121. 23 Sclerorinus stewartr, Macl.(?)—South Australia: Blinman. Nearest to S. stewarti, but smaller than type. The last three species are undoubtedly close to one another, but differ in the relative size of the tubercles and to some extent in the clothing. S. teniatus, Pasc., appears to be synonymous with S. stewarti, Macl. Sclerorinus sublineatus, Germar.—South Australia: Moonta, Peterborough, Blanchetown, Adelaide, Balaklava. A large series of specimens showing con- siderable variation in size, comparative width, and in the size of the elytral tubercles. S. marginatus, Pasc., 1s synonymous. One specimen was labelled “Northern Territory,’’ probably an error. Sclerorinus pilularius, Macl.—South Australia: Mus- grave Range (R. T. Maurice), Wilgena (L. C. Staple- ton), Ouldea. Close to the last species but larger, more ovate, and with somewhat different clothing. Sclerormmus, sp.(?)—A_ single Q without locality, possibly a variety of S. sublineatus, Germar. Sclerorinus tuberculosus, Macl.—Victoria. Sclerorinus germart, Macl.—South Australia. Speci- mens agree with types (?) in Macleay collection. In addition to these typical specimens were a number of others which I prefer to regard as varieties rather than as distinct species. 1. ¢g. No locality. Differs in having the median ventral vitta of a dark-brown colour. 2. 3, Q. Wilmington. The ¢ is a much longer and narrower insect than the type of germarv. 3. do, Q. Kangaroo Island. Differs in having the elytra somewhat longer in proportion to the pro- thorax, and in the sete being of a yellowish colour. Sclerorinus parvulus, Macl.—South Australia. Speci- mens sent agree with the type(?) in the Macleay collection. It is, however, doubtfully distinct from S. germari, differing merely in the prothoracic granules being more rounded and less obsolescent. Sclerorinus mucronipennis, 0. sp. — Sclerorinus wmconstans, Lea.—New South Wales: Mount Kosciusko. Sclerorinus alpicola, n. sp. Sclerorinus dilaticollis, Macl.—South Australia. Sclerorinus horridus, Macl.—South Australia: Fow- ler Bay, Port Lincoln, Ardrossan, Blanchetown, 122. 123. 128. AS 24 Moonta, Terowie. One labelled ‘‘Northern Territory,’’ probably an error. The series shows great variation in size, clothing, and size of tubercles, so that it is somewhat difficult to obtain two specimens exactly alike. Sclerorinus riverine, Macl.—Victoria. A pair from Blackburn’s collection sent under the synonym S. alternus, Macl. Sclerorinus bubalus, Oliv.—Tasmania; South Aus- tralia. This is the first record of this common Tas- manian species from South Australia; it also occurs in Victoria. . Sclerorinus subcostatus, Macl.—New South Wales: Yass. . Sclerorinus, sp. (?)—No locality. I have this species from Harden, New South Wales. It is close to S. squalidus, but probably undescribed. . Sclerorinus, sp. (?)—New South Wales: Mulwala (T. G. Sloane). Three specimens of a widely distributed species. It agrees fairly well with the descriptions of S. hoper; I have, therefore, deferred dealing with it until specimens can be compared with the type. . Amycterus leichhardtt1, Macl.—Western Australia. A o¢ marked “‘compared with type.’’ Amycterus schiénherri, Hope.—Western Australia: Swan River. Amycterus draco, W. 8S. Macleay.—Western Aus- tralia. The series sent for examination shows con- siderable variation in the number of tubercles com- posing the median rows on the prothorax. Ail the specimens show granularity of the derm between the elytra tubercles, but less marked than in the type, and in this respect the specimens approach closer to the variety insignis.4 Both the number of pro- thoracic tubercles and the granularity of the derm appear to vary independently. The typical characters of draco are the combination of few prothoracic tubercles (4-5) with an asperate derm; those of msignis are numerous tubercles (typically about 12) combined with an almost smooth derm. Examples of specimens with few tubercles and an almost smooth derm are not uncommon, but in the asperate speci- mens the prothoracic tubercles are rarely more than seven in number. (4) Awaiting publication in my Revision of the Amycterides. 25 PSALIDURA BREVICAUDA, Ni. sp. 3. Moderately large, elongate, subparallel. Black; densely clothed with greyish-brown scales; beneath with yellow subsetose scales at sides of segments and yellow setz scattered throughout, fifth segment similarly clothed, and on. forceps and apical ptergite, also with longer stouter setz ; sete yellow ; fascicles dark-brown. Head strongly convex, densely clothed, sparingly setigero- punctate. Rostrum short, moderately deeply excavate, ex- ternal ridges feebly bisinuate in outline, internal less pro- minent, short, strongly convergent, but apices separated. Hyes large, ovate. Prothorax (7x7 mm.) strongly rounded on sides, apex with median lobe strongly produced over head, ocular lobes well defined but less prominent, collar impression moderately marked, median line feeble; disc evenly and closely set with small, round, little prominent, strongly seti- gerous granules; sides granulate. Hlytra (12 x8 mm.) little widened on sides, apex strongly rounded, feebly mucronate, base subtruncate, humeral angles subnoduliform ; with rows of small regular foveiform punctures, intervals between setigerous but not granulate; interstices with small round setigerous granules, on second, fourth, and sixth in single, on the others in double, series; sides similar. Metasternum rather strongly depressed in middle. Fifth segment strongly excavate, anterior border of excavation hardly reaching anterior margin of seg- ment, preanal fossa deep, transversely oval, not separated from rest of excavation by a ridge, posterior margin of seg- ment lightly fringed with setz ; fascicles set obliquely inwards and downwards 2 mm. apart at base, 1 mm. at apex. Forceps with apices alone evident, short stumpy, not meeting, laminz present, very small and only visible from behind; apical tergite bearded with yellowish hair. Q. Of a more elliptical shape, in structure closely resembling ¢; beneath convex, intermediates longer, fifth without excavation, clothed with yellow sete except over small bare area in centre. Dim.— 3, 20x8mm.; 9, 20x8 mm. Hab.—Queensland : Dalby (Mrs. F. Hobler, per A. M. Lea), Fraser Island (Bailey, South Australian Museum). Type in author’s collection. One of the most remarkable species in the genus, not only in the short forceps and curiously placed fascicles, but in the very regular foveate elytral sculpture. It is not close to any other known to me, and cannot with propriety be forced into any of the groupsin my table. Provisionally it may be formed into a new group, in the table coming near the end and 26 ‘distinguished from the other groups with short forceps, by the well-developed fascicles and the form of the metasternum. PSALIDURA FLAVESCENS, Nh. Sp. 3. Moderately stout, robust, in appearance close to perlata. Black; densely clothed with bright-yellow sub- pubescence or scales, covering all upper parts except rostral ridges, portion of head, and granules below, present on meta- sternum, and feebly on ‘segments where scales are more setose ; granules with long bright-yellow sete, legs with stout sete. Head and rostrum as in perlata, frontal impression shallow, clothing forming a median and supraorbital vitte. Prothorax (5 x 6 mm.) with smaller and more separate granules than in perlata, each with a long seta. Elytra (115 x 8 mm.) much as in perlata, densely clothed, intrastrial ridges trace- able, setigerous; interstices with distinctly smaller granules, for the most part in double series, setz long. Metasternum and anal segment as in perlata, except that excavation is less nitid. Dim.—63,19x8 mm. Hab.—South Australia: Eucla (C. French), Port Lincoln {South Australian Museum). Close to perlata, but with very different clothing and noticeably smaller granules. Type in author’s collection. TALAURINUS MACULIPENNIS, Lea. Var. BREVIOR, Nn. var. 3. Differs from typical specimens in being shorter and comparatively stouter; clothing with hghter portions predom- inating, sete rather stouter, of a brighter yellow colour; pro- thoracic granules more distinct, not obscured by clothing: elytra with the intrastrial eranules rather more prominent, the setz distinctly more evident ; otherwise as in type. Dim.—¢6,12x5mm.; 9, 12x55 mm. Hab.—Western Australia: Eucla (C. French); South Australia (South Australian Museum, without exact locality). Type in author’s collection. I have had specimens of this form under observation for some time, and while I do not regard them as specifically distinct, I think that the differences noted above are sufficient to entitle the form to subspecific rank. “TALAURINUS FLAVEOLUS, 0. sp. 3. Small, elongate-ovate, of type of 7. semplicipes. Black, densely clothed with oreyish or yellow SU eS sete light-yellow. 27 Head gently convex, continuous with rostrum in same plane above, with a few scattered sete. Rostrum short, hardly excavate, save for depression behind apical plate; internal ridges hardly distinct; three impressions traceable at base, a median linear and an oblique somewhat curved foveiform impression on either side. Scrobes simple. Eyes subovate. Prothorax (2°5x 3 mm.) widely and evenly rounded on either side, apical margin with very feeble postocular sinuation ; disc without impressions, granules practically obsolete, some- what more evident at sides, each with a long stout decumbent seta arising posteriorly and projecting backwards. Elytra (6x4 mm.) gently rounded on sides, apex moderately strongly rounded, strongly declivous posteriorly, base almost truncate, humeri very slightly thickened, not projecting; disc with sculpture practically obliterated, no strie traceable, on abrasion small obsolete granules to be seen, rendered slightly evident by the feeble rugosity of derm. Clothed with dense subpubescence and with long stout sete arising from the obsolete granules and traceable into rows according to the in- terstices and into intermediate rows corresponding to the intrastrial granules. Beneath with light scattered sete ; inter- mediate segments moderately long; fifth segment lightly con- cave, a deeper transverse sulcus along posterior margin, not reaching sides, but bounded at each end by a small tubercle on the anterior edge. Middle tibiz simple. Q. Similar but more robust; rostrum with median area more definitely impressed ; prothorax (3 x 35 mm.) and elytra (7x5 mm.) similarly sculptured; beneath convex, inter- mediates longer, fifth with a shallow somewhat irregular fovea surrounded by a few punctures. Dim.—d,95x4mm.; 9, 11x5 mm. Hab.—Western Australia: Esperance Bay (¢), Eucla (Q), Blackburn’s collection; Eucla (Q), (C. French), collec- tion Ferguson. I have had a single Q of this species under observation for some time; the presence of both sexes in the South Australian Museum collection has given me an opportunity of describing it. The clothing of the 3 has been somewhat abraded and apparenty discoloured ; in both females it is of a bright-yellow and in one variegated with grey or white, the prothorax being also feebly trivittate. As seen from above the sculpture appears almost entirely obliterated; viewed from behind, owing to the foreshortening, shallow punctures become evi- dent arranged into longitudinal rows. Of previously described’ species it comes nearest to 7. simplicipes, Lea, but differs in. the sculpture clothing and sete. Type in South Australian Museum. 28 TaLAURINUS PLAGIATUS, Nl. Sp. gd. Size, shape, and general appearance of 7. septen- trionalis, intermediate tibiz without subapical notch. Black, rather densely clothed with dingy-grey subpubescence, an obscure dark patch at each humeral angle, a few small indis- tinct dark maculz on disc; beneath with fairly close silvery subsetose clothing; setz dark-brown. Head strongly convex, separately so from rostrum. Rostrum short, strongly excavate in front; external ridges sub- parallel; internal prominent, little convergent; median area ‘depressed, sublateral sulci long, subparallel. Scrobes feebly curved, well defined, not reaching eye. Eyes rather large, ovate. Scape rather short, stout, strongly curved, incrassate, but not ampliate or explanate at apex. Prothorax (3x4 mm.) rather strongly widened, subangulate at sides, anterior to middle; apex with moderately distinct median lobe, but feeble ocular lobes; postapical constriction ill-defined but moderately strongly impressed, median line indefinite; with small obscure granules fairly closely set, rounded, somewhat irregular towards middle with tendency to coalesce longi- tudinally; sides granulate. Elytra (7 x5 mm.) ovate in out- line, base subtruncate, humeri marked but not produced, apex strongly rounded, posterior declivity steep; with rows of open shallow fovez in striz, the granules between small and little evident ; interstices little raised, alternate ones rather thicker, setigerous but hardly evidently granulate, the whole sculpture somewhat obscure. Beneath with intermediate ventral seg- ments moderately long, flat; fifth segment feebly and indefin- ably concave in middle near apex. Forceps hardly visible in position, short, with moderately broad laminz set obliquely across inner face. Anterior tibie strongly angulate at apex, intermediate without subapical notch. ©. Similar, more ovate; under-surface convex without impressions, anterior tibiz not so strongly angulate at apex; disc with granules feeble but slightly more evident. Dim.— 3,11x5; 9, 11x55 mm. Hab.—North Queensland (Blackburn). Type in South Australian Museum. A small obscure species in appearance strongly resembling T. septentrionalis, but with simple tibie. It is perhaps closest to T. panduriformis, but, besides being smaller, it has more evident prothoracic granules, and rather more regular elytral sculpture, the punctures being more definite and the inter- mediate interstices (%.e., the second and fourth) with more evident setz set close together; the difference in the humeral angles is also very marked. 29 TALAURINUS PULVERULENTUS, Macl. Var. PROSTERNALIS, n. var. d. Of size and general structure of typical specimens ; antennal scape slightly more curved and rather more incrassate at extremity; prosternum with a narrow transverse carina in front of anterior coxe, terminating abruptly at each end; metasternal tubercles situated slightly internal to middle trocanters and nearer to each other than in type. Q. Similar to 9 of typical specimens except that scape is slightly thicker. Dim.—¢,11x4mm.; 9, 12x5 mm. Hab.—Central Queensland: Longreach (A. M. Lea). Except in regard to the ridge on the prosternum and the approximation of the metasternal tubercles, this form does not differ from 7. pulverulentus, for the difference in the antennz is slight and only appreciable on careful comparison. In 7’. pulverulentus the metasternal tubercles are evidently farther apart; they are situated behind and a little towards the outer side of the middle trocanters. Type in the South Australian Museum. TALAURINUS CARINATIFRONS, Nn. Sp. 3d. General facies that of T. caviceps. Black, densely clothed above except on elevations with greyish scales, beneath with similar more scattered clothing on middle and sides of each segment. Head convex, forehead concave between the ends of the ridges ; marked with three ridges, a prominent rounded one on each side, the prolongation back of the external rostral ridges, and a shorter, much finer, and more sharply defined ridge or carina in centre. Rostrum moderately deeply excavate, ex- ternal ridges thick, rounded, slightly convergent basally, con- tinuous with lateral ridges on head; internal ridges but little prominent, median area little depressed below level of internal ridges, sublateral sulci long, deep and foveiform at base, shallow anteriorly. Scrobes simple, not reaching eyes. Eye subrotundate. Prothorax (5x6 mm.) evenly rounded on sides, ocular lobes moderately well defined, median line not impressed but without granules; disc with numerous discrete rounded granules or tubercles, somewhat irregular in size and distribution. Sides granulate. Elytra (13x 8 mm.) evenly rounded on sides, apex rather strongly rounded, base gently arcuate, humeri marked by out-turned nodule; with rows of small shallow open foveiform depressions obscured by clothing, each separated from the next above and below by a small nitid granule; interstices with small rounded somewhat 30 flattened tubercles, numerous and forming continuous rows o1r first, third, fifth, and sixth, fewer, larger, and more widely separated on second and fourth, on second about eight, on fourth four to five in number. Sides with numerous rounded. nitid granules. Fifth segment .with a moderately deep con- cavity occupying the middle two-fourths, with a deeper trans~ verse sulcus along posterior margin. Anterior femora not ridged. Q. Similar but more robust, head with median carina. less evident, third interstice showing tendency to reduplica- tion of the tubercles in the basal half. Beneath convex, fifth segment with irregular shallow transverse impression at ex- treme apex. Dim.—c, 21 x8mm.; 9, 21x85 mm. Hab.—South Australia. Type in author’s collection. I have long had a specimen of this species in my col- lection, but merely regarded it as a form of caviceps. The examination of a number of specimens in the South Australian Museum collection at once showed the difference from that species, the tubercles both on prothorax and elytra being con- siderably finer. TALAURINUS HALMATURINUS, N. sp. d. Large, elongate-ovate, general facies that of T. verrucosus. Black, tubercles subnitid, practically without. clothing. Head strongly ridged on each side above eye, middle of forehead with a feeble longitudinal carina. Rostrum strongly excavate, especially in front, external ridges subparallel, con- tinued on to head; internal less prominent but distinct, moderately long, convergent; sublateral sulci long, rather deeply impressed, median area depressed. Scrobes ending dis- tant to eye, with a feeble prolongation upwards and backwards. Prothorax (5x 6 mm.) evenly rounded on either side, apical margin subtruncate above, ocular lobes feeble; disc with isolated rounded tubercles, rather farther apart in middle. Sides with tubercles becoming obsolete towards coxe. LHlytra: (12x 8 mm.) evenly rounded on sides, base arcuate, humeri marked by out-turned tubercle; disc with punctures irregular, hardly traceable into striz, also with scattered setigerous granules; with rows of tubercles corresponding to the inter- stices, moderately large, rounded anteriorly, conical and more spinose posteriorly and laterally, the second interstice with four distantly placed, the last on declivity, third interstice with about ten extending just on to declivity, the tubercles isolated but closer together than on second, fourth with two: 31 near middle, five with about eight, sixth with six forming lateral border; sides with tubercles subobsolete and closer. Beneath with small scattered setz, intermediate segments long ; fifth with shallow impression occupying a little more than middle two-fourths, deeper posteriorly and with a deep narrow somewhat boat-shaped fossa at extreme apex. Anterior femora not ridged. Q. Similar to ¢ but more robust, with elytral tubercles somewhat more numerous; beneath strongly convex, fifth segment with only a shallow transverse apical impression. Dim.—¢d, 20x8 mm.; 9, 22x9 mm. Hab.—Kangaroo Island. Type in South Australian Museum. Very close in general appearance and elytral sculpture to JT. verrucosus, Guér., but, wmter alia, with somewhat different excavation of fifth ventral segment. The excavation in both species is on the same general plan, but is much deeper in T. verrucosus, while the tubercles at the sides are not developed in 7. halmaturimus,; the internal rostral ridges are _ also more evident in the Kangaroo Island species. 7’. tuber- culatus differs again in these respects. TALAURINUS BUBAROIDES, Nl. Sp. | @. Small, ovate. Black, densely clothed with yellowish or grey subpubescence, completely covering the granules; sete small, light coloured. - Head as viewed from above about twice as wide across eyes as width across external rostral ridges at apex, sides nar- rowed with slight curve outwards from behind eyes to base of rostrum. Rostrum little excavate, median area wide, shallow, and open; width across external ridges much less than width of rostrum, ridges not prominent, slightly diver- gent backwards; internal ridges little prominent, sublateral sulci small, foveiform at base, becoming rapidly shallower anteriorly ; sides of rostrum greatly bulged out below scrobes. Scrobes somewhat curved with shallower extension continuing curve back and downwards to orbit. Scape moderately long, normal. Eyes rotundate. Prothorax (3x 4'5 mm.) strongly transverse, sides strongly angulate in middle, narrowed to base and apex; ocular lobes rather well marked. Disc strongly convex from side to side, with median impressed line and strongly marked, somewhat flattened, impression on each side, making the lateral margins appear almost explanate. Granules small, discrete, densely clothed but readily traceable, absent along longitudinal impressions, clustered more thickly around lateral angle. Elytra (7x55 mm.) rather strongly 32 widened posteriorly, apex moderately rounded ; base somewhat deeply emarginate, humeral angles projecting forwards, nodu- liform, basal end of third interstice also projecting forwards, less strongly noduliform. Disc with rows of small closely-set shallow punctures each subtended by a small granule; third and fifth interstices more prominent than the others, sutural with five granules, second with three or four small tubercles spaced out on interstice, third and fifth each with row of small closely-placed tubercles from base to middle, thence with a few isolated tubercles extending down declivity, fourth with three tubercles similar to second, sixth with row of about eight regularly and closely placed. Beneath gently convex; fifth with small transversely oval foveiform depression at extreme apex. Dim.—Q, 115x5'5 mm. Hab.—South and Western Australia: Ouldea, Fowler Bay, Eucla. Of this distinct species I have five specimens under exam- ination, all apparently of the one sex and probably females. IT have not hesitated to describe it, as it is a thoroughly distinct species. In general appearance it somewhat resembles Sclerorinus horridus, and I long had a specimen under that name. In Blackburn’s collection there is a specimen named S. parvulus. It is, however, certainly not a Sclerorinus, and though tentatively placed in T'alaurinus probably requires a new genus. I have selected a specific name in accordance with a superficial resemblance to Bubaris pubescens. There is a strong connection between this species and T. scaber, Boisd. ; the rostrum in the latter species is rather longer and has the internal ridges raised at base, but is very similar in appear- ance, the shape of the thorax is practically the same, the elytral tubercles, however, are different. Type in author’s collection. TALAURINUS SPINIGER, Nl. Sp. Q. Of moderate size, robust. Black, with feeble muddy clothing ; sete small, black; no median ventral vitta. Head convex, broad, with two impressions in front con- tinuous with sublateral rostral sulci. Rostrum short, width across external ridges considerably less than width across sides, external ridges somewhat convergent to base, internal ridges subobsolete, only indicated by the position of the sub- lateral sulci, these obliquely set, deep, foveiform at base, becoming shallower anteriorly, median area gently and evenly concave. Scrobes short, somewhat curved, ending distant from eye. Eyes small, round. Scape of moderate length, not much 33 incrassate. Prothorax (5x6 mm.) strongly transverse, sides bulged out and subangulate in middle; apical margin widely rounded above with moderately deep postocular sinuation. Disc strongly convex from side to side, more gently from before backwards, set with small rather prominent separate tubercles, absent along median and sublateral lines. Elytra (9 x7 mm.) robust, apex moderately strongly rounded, base very gently arcuate, humeri marked by outwardly projecting tubercle; with rows of small punctures separated by small granules, the lines obscured and broken up by the interstitial tubercles; suture with row of small granules, larger and out-turned at base, the cther interstices with strong conical tubercles larger and more acutely pointed posteriorly, second with four to five, situated moderately close together about middle of interstice, third with a continuous row of ten to twelve from base to declivity (on one side with a small tubercle on declivity), fourth with one or two separate tubercles near middle, fifth with three to four moderately close together starting from shoulder and three or four others more unevenly spaced out, sixth with three near middle. Beneath convex; fifth seg- ment with a foveiform impression near apex. Dim.—Q2,15x7 mm. Hab.—Australia; no locality given. Type in South Australian Museum. South Austraha (National Museum, Victoria). Though represented by female specimens only, the insect appears so distinct that I have not hesitated to describe it. Its immediate affinities are not obvious, but it shows some points of resemblance to both 7. bubaroides and T. incanescens, probably when the ¢ is known its position will be more apparent. SCLERORINUS NEGLECTUS, 0. sp. 3. Hlongate-ovate. Biack, cpaque; densely clothed with grey and brown, trivittate with grey on head and prothorax, the median vitta subdivided on head and rostrum by median carina, elytra maculate; below last three segments maculate with yellow in middle and with sparse grey sete near sides. Sete dark-brown. Head continued on into rostrum without interruption, the lateral and median carinz continued up forehead, the median almost to vertex; rostrum not greatly excavate, sublateral sulci shallow with deeper foveiform pit at base. Prothorax (4x5 mm.) rather strongly rounded on sides, not greatly ampliate, ocular lobes moderately prominent; disc with well- defined subapical impression and deeply impressed median line, somewhat sparingly set with moderately large somewhat fo) 34 depressed granules, elongate in middle, more rounded towards sides. Sides granulate. Elytra (11 x6 mm.) gently rounded on sides, apex moderately strongly rounded, base gently arcuate, humeral angles rather feebly out-turned, noduli- form; disc with rows of small punctures obscured by the clothing, subtended by sete but no definite granules between the punctures; interstices broad and flat where tubercles are wanting, second with two or three subconical tubercles, spaced out between middle and apex, third with a more con- tinuous row of elongate rather large tubercles about ten in number, more spaced out and subconical posteriorly, fourth without tubercles, fifth with a row more closely placed, rather smaller and more rounded about fourteen in number, sixth with a similar row of about eleven. Sides with rather pro- nounced somewhat tortuous tubercles. Fifth ventral seg- ment with a narrow median channel not very deep, bordered on each side behind middle by a triangularly raised ridge or tubercle. Anterior femora not ridged beneath, inter- mediate tibie with a deep subapical notch. @. Similar but larger and more ovate, with the apex decidedly produced and obtusely mucronate; beneath convex, fifth segment with median channel not bounded by tubercles ; intermediate tibize with much feebler notch. Dim.—d,6x6mm.; 9, 20x8 mm. Hab.—South Australia: Port Lincoln (Macleay Museum, South Australian Museum). | All the specimens, with the exception of a pair in the Museum collection labelled Northern Territory (probably an erroneous locality), are from the Port Lincoln dis- trict, where the species appears to be common. The series shows great variation both in the _ prothoracic and elytral sculpture, in some specimens the prothoracic granules are much smaller, more elongate, and showing a distinct tendency to become obsolete in the middle; the tubercles on the elytra are often variable, in particular those on the more lateral interstices. Some specimens show a decided approach to S. regularis, and it is questionable whether that species should not be regarded as an extreme variation of S. neglectus. Though in most Australian col- lections the species appears to have been overlooked by pre- vious describers. : Type in author’s collection. SCLERORINUS REGULARIS, Nh. Sp. 3. Size moderately large, convex, subparallel. Black, densely covered with yellowish-brown clothing; sete light- 35 brown ; ventral segments maculate with lighter in middle and at sides. Head convex, upper-surface practically in same plane with that of rostrum, forehead with three ridges, the exten- sion backwards of the rostral carine. Rostrum broad, the carine on upper-surface distinct, transversely convex, the median carina narrowing slightly to base and widening some- what on head; sublateral sulci long, foveiform at base. Head ‘and rostrum remotely and subobsoletely punctate. Prothorax (5x6 mm.) moderately ampliate, widest in front of middle; ocular lobes rather prominent. Disc convex, median impres- sion rather ill-defined, apical impression only traceable at sides; closely set with smail regular rounded tubercles, not noticeably depressed; sides granulate. Elytra (11 x7 mm.) gradually but not greatly widened to behind middle; base arcuate, humeral angles marked by small tubercles. Disc with regular rows of shallow impressions, separated by small setigerous granules concealed by clothing; interstices tuber- culate; second with three isolated elongate tubercles near middle; third with a regular row of fifteen, closely set, ex- tending from base half-way down declivity, rounded basally, subconical on declivity; fourth without tubercles; fifth with a continuous row of twenty-two smaller rounded tubercles; sixth with nine intermediate in size and not extending to base. Sides with tubercles obsolete. Apical ventral segment with a strong median channel bordered on either side by a small tubercle. Anterior femora with a feeble indication of a ridge beneath; intermediate tibie with a strong subapical notch. ©. More robust and ovate in outline; beneath convex, the fifth segment with a feeble median impression; anterior femora not ridged; intermediate tibie wtih a feeble indica- tion of a subapical notch. Dim.—¢d,18x7mm.; 9, 20x9 mm. Hab.—Gawler Ranges (F. Andrews, South Australian Museum, type). The notch on the intermediate tibie will separate the species from all, except S. neglectus and S. dimidiatus, of the members of the first section of the genus. From S. neg- lectus its larger size and in general more robust form will, in addition to the ‘more marked differences in the prothoracic and elytral sculpture, help to distinguish it. To this species I refer with some slight doubt specimens from Port Lincoln ; these latter, however, show a decided tendency towards S. neglectus and lead me to question whether both forms do not belong to the one variable species. I do not think, however, that this is really the case. S. dimidiatus, Macl., is founded c2 36 on an isolated specimen from Flinders Range; it agrees with S. regularis in the rounded character of the prothoracic granules, but differs in having the third interstice subcostate. ScLERORINUS ALBOVITTATUS, Nl. Sp. ¢. Elongate-ovate, size moderate. Black; densely clothed with yellowish-brown subpubescence; head trivittate, the median vitta subdivided by a median bare line, prothorax trivittate with white, the median vitta narrow, elytra with white vittz along the third and fifth interstices; sides of head, prothorax, and lower border of elytra with white, the white clothing more squamose in character; under-surface with whitish macules on middle and sides of segments forming interrupted vittz, last segment with white clothing distributed over whole surface. Rostrum with median line bare, not definitely raised, extending up on to and along forehead, basal fovee moder- ately deep. Prothorax (4x5 mm.) transverse, moderately ampliate on sides, ocular lobes rather feeble. Disc convex, with transverse subapical impression and feebly impressed median line, set with round somewhat-depressed setigerous granules moderately close together, obsolescent along vitte; sides granulate. Elytra (10x 6 mm.) evenly rounded, not greatly widened on sides, base gently arcuate, humeral angles marked but not produced. Disc with punctures obscured by clothing but apparently small and shallow; interstices tuber- culate, the tubercles small, becoming somewhat larger pos- teriorly, feebly conical on declivity; second with five or six isolated tubercles, not extending down declivity, third inter- stices tending to approximate on declivity, with a row of about twelve from base nearly to apex, fourth with three anterior to middle varying in position, fifth with three at humeral angle only, sixth with a closely set row of twelve; sides with regular rows of rounded tubercles. Fifth ventral segment with small median impression at extreme apex, bordered on either side by a small tubercle obscured by clothing. Legs simple. 2. Similar to 3 but somewhat more ovate, and convex beneath. Din 6) xe bam O° a) c/a Hab.—Western Australia: Eucla (C. French and South Australian Museum). Though in general appearance close to species of the type of S. germari, and, lke that group, with the fifth interstice only tuberculate at shoulder, the structure of the fifth ventral segment points to a closer relationship to the adelaide group, though it is very distinct from any other described species of 37 the group. The median macules tend to form a distinct median vitta, but it has not the hirsute character of species in the vittate groups. Most of the Museum specimens are without. locality. Type in author’s collection. SCLERORINUS BLACKBURNI, 0. sp. 3. Elongate, subparallel, strongly tuberculate. Black; clothing dense. rich-brown, on head forming median and sub- lateral vittz: a brownish patch on either side between vitte; whitish on prothorax forming feeble sublateral vittz and faintly indicated in middle line; elytra with inner- surfaces of tubercles clothed with white; sides of prothorax and elytra with white. Beneath with a dense tomentose vitta of a rich ruddy-brown colour. Setz black. Head strongly convex, the upper rostral surface not in same plane as head, forehead flattened in front, external rostral ridges extending back with a slight change of direction on to the head. Rostrum broad, evenly though not deeply excavate, external ridges slightly divergent posteriorly, median carina narrow, distinctly raised, not extending upon head, sublateral sulci broad, shallow, with smaller deeper foveiform depressions at base. Eyes subrotundate. Prothorax (6 x 75 mm.) dilatate, subangulate on sides anterior’ to middle, post- ocular sinuation of apical margin moderately strong but lobes not marked ; disc with evident transverse subapical impression, median line free from tubercles, sublateral lines irregularly impressed, free from tubercles; elsewhere with strong irregular somewhat depressed tubercles, rounded or slightly transverse. Sides with granules decreasing in size from above down and not continued to coxe. Elytra (15 x8 mm.) elongate, little widened, apex almost subtruncate, with a strong granulate flange; base feebly arcuate, humeri with single, outwardly ‘directed, tubercle. Disc with rows of small shallow foveiform punctures obscured by clothing, each subtended by a small, setigerous granule; interstices tuberculate, sutural with a row of fine granules larger at base ; second with four large spinose tubercles, black, spaced out and uniformly placed on the two sides; third with a continuous row of strong spinose tubercles, upwardly, backwardly somewhat outwardly directed, nine on left, twelve on right in type; fourth without tubercles; fifth with humeral tubercle only, followed by a small granule, thence interstice only traceable by a row of setz; sixth with a continuous row of large outwardly-directed tubercles, ten in number. Sides with rows of rounded granules or tubercles diminishing in size in successive rows. Under-surface with deep groove on either side of vitta on first and second segments, the 38 others somewhat irregular, hardly rugulose, non-granulate, with a few sete. Anterior femora ridged beneath. Middle tibiz simple. Dim.—6d3, 24x 8 mm. Hab.—Northern Territory; South Australia: Cleve (Blackburn). } Type in South Australian Museum. Two specimens, both males, from the late Rev. T. Black- burn’s collection, in memory of whom I have named it. I regard it as probably the finest species yet described in this genus. Itis most nearly related to S. biordinatus, but differs decidedly in clothing, and in the much larger tubercles both on thorax and elytra; the strong dark tubercles contrasted against the rich almost reddish-brown clothing should render it easy of identification. Although the type is labelled Northern Territory, it seems improbable to me that this species should range from Cleve in Yorke Peninsula, South Australia, to the Northern Territory, particularly as the other members: of the genus are almost all restricted in their habitat. Fur- thermore, the only other species of Sclerorimus in the present collection labelled as coming from Northern Australia are species whose known habitats are in the south of South Aus- tralia. The possibility suggests itself, therefore, that all these species have through some error been wrongly labelled. SCLERORINUS ALPICOLA, 0. sp. or var. 3. General facies that of S. inconstans, Lea, but slightly smaller and somewhat narrower. Black, legs sometimes diluted with red; clothing much as in S. inconstans, but rather lighter, brownish with whitish vitte, head trivittate, median vitta subdivided into two, prothorax trivittate, elytra with rather feeble vittze traceable along the two inner and two outer striz ; with median black hirsute vitta along under- surface. | Head with external rostral ridges continued for some dis- tance along each side of forehead, median rostral carina dis- tinctly elevated, continued on to head but interrupted at junction of head and rostrum, sublateral fovez moderately deep. Prothorax (4x 4°5 mm.) widest anterior to middle, ocular lobes rather feeble; set with fine scattered granules, larger in apical third, generally smaller than in S. enconstans. Elytra (10x 6 mm.) less dilatate than in S. wnconstans, rows of punctures similar but tubercles on interstices smaller and fewer in number; second with two or three, third with five or six unevenly spaced over whole length of interstice, fourth without any, fifth variable in number and position of the tubercles, these not forming a closely-set row but spaced out 39 over length of interstice, sixth with tubercles somewhat smaller but more regular and closer together. Apical ventral segment with a concave depression slightly shallower than in S. meonstans. Legs simple. QO. Somew hat more ovate than the male ; beneath convex, with a much feebler brownish vitta. Dim.—é,16x6mm.; 9,17x7 mm. Hah.—Victoria: Mount Baldy (H. J. Carter), Victorian Alps (Rev. T. Blackburn). Close to S. inconstans, Lea, of which it might well be regarded as a variety; as, however, a fairly extensive series shows little variation in the size of the tubercles and in other points, I think it justifiable to propose a distinct name for the southern form. The prothoracic granules are not noticeably smaller than in the type of S. wconstans, but they are decidedly smaller than the majority of specimens from Mount Kosciusko; the elytral tubercles are also smaller, and as a general rule are fewer in number. The clothing is described from a specimen in good preservation, but the majority of specimens are abraded or discoloured and the vitte obscured. Type in author’s collection. SCLERORINUS MUCRONIPENNIS, N. sp. Q. Size small, ovate, moderately robust, general facies that of S. germari. Black, densely clothed with dark-brown subsquamose clothing, vittate with white, head trivittate, the median vitta bifurcate on the rostrum, prothorax trivittate, elytra with two longitudinal vitte on each side, one internal to third interstice, the other along lateral border, sides of pro- thorax and elytra with white along lower edge. Beneath with a feeble median greyish vitta. Setz brownish. Head continued into rostrum without interruption, the external ridges running on to forehead, forehead not carinate in middle; rostrum not excavate, median carina not greatly raised, subtriangular in front, narrowed at base, a small fovea present on head at base of median carina; sublateral basal foveze rather deep. Eyes rotundate. Prothorax (4x5 mm.) rather strongly ampliate on sides, ocular lobes some- what feeble, disc with well-defined subapical transverse impression, median line hardly impressed; set with small rounded granules, depressed and obsolescent towards centre, becoming larger and more evident towards sides; sides granu- late. Hlytra (9x 6 mm.) ovate, apex rounded, with a small emargination at suture bounded on either side by a short mucro situated at end of third interstice; base subtruncate, humeri marked by a small tubercle, not at all advanced. Sculp- ture of disc confused, punctures small, shallow, intervening 40 ridges setigerous, not definitely granulate; interstices with small tubercles, their apices pointing backwards, suture with only a few elongate granules at base, second with four or five separate tubercles not reaching base nor extending down declivity, third with a more or less continuous row of thirteen from base extending half-way down declivity, the basal tubercles somewhat elongate, the apical ones more subconical, fourth with two or three in middle, fifth with a few at humeral angle rapidly diminishing till only traceable by a row of sete, sixth with a continuous row of twelve more rounded tubercles ; sides with rows of round rather flattened tubercles. Beneath convex. Intermediate tibize with feeble indications of a sub- apical notch. Dim.—Q,13x6 mm. Hab.—Victoria: Nelson (Rev. T. Blackburn). Contrary to my usual custom, I have selected a female as the type of this species, partly because the chief specific dis- tinction hes in the mucronate elytra of this sex, partly because I have seen no male from the same locality as a female. In the Museum collection, however, there is a male from Kingston, a neighbouring town in South Australia, which, I believe, belongs to the same species. It is narrower and more elongate (135x5 mm.), and has the prothcracic granules less obso- lescent in the centre, the elytral tubercles are more elongate, below there is a golden-brown median hirsute vitta, the anterior femora are ridged beneath and the middle tabie have a strong subapical notch, also the elytra are not mucronate. The specimen is greatly abraded, but has sete of a light- yellowish colour ; this, however, appears to be a variable char- acter, as the colour differs in the females also. Apart from the mucronation there is little to distinguish this species from S. germari or S. parvulus; as, however, I have five females before me, all exhibiting the same mucronation, I can only regard this as constant and of specific value. A female from the Howitt collection, National Museum, Melbourne, belongs to this species; it is labelled S. mucronatus, Macl.

[Read April 2, 1914.] Typical examples of the principal rock formations observed in the Central Australian region to the present time are as follows, viz.:—(1) Tertiary to Recent: gypsum beds of Lake Eyre, Burt Plain shale, tops of hills around Lake Eyre ( 2) ; (2) Lower Cretaceous: Lake Eyre blue shales; (3) Jurassic ( 2) : Finke River sandstones; (4) Post Ordovician: Ellery Creek conglomerate ; (5) Ordovician: South MacDonnell Ranges (in part); (6) Cambrian: South MacDonnell Ranges (in part) and MacDonnell Ranges (in part); (7) Pre-Cambrian: crystalline schists, granite, etc., of the central plateau. TERTIARY. The township of Oodnadatta stands upon gypseous sand- stone beds which were deposited after the Cretaceous shale beds had been eroded well down towards their present level of erosion. Its total thickness may have been 100 to 200 ft. Before erosion started on these gypsum beds only the higher levels of the valleys remained unfilled. The remnants show that the formation was laid down upon the uneven bottom and sides of the valley of the Neales River, in a continuous sheet, that stretched horizontally for many miles. The Neales River has since cut its way right through the gypsum beds and down into the former floor of the valley, perhaps another 50 ft. It would be interesting to know whether the quartzite capping to the Cretaceous beds was in existence or not when the gypsum beds were laid down. If so, fragments of the porcelainized sandstone should be found at the base of, and also in, the gypsum beds where they impinge on the Cretaceous shale, unless they were dissolved. On the Burt Plain, a few miles south of Burt Well on the central plateau, are low-lying beds of shale and ferru- ginous sandstone, calcareous grit, indurated clay, etc. These beds occupy the bottoms of the valleys and represent the older wash as the watercourses gradually filled to the present level of the sand plains. Similar deposits occur in nearly all the valleys over the plateau, in which many successful wells have been sunk. These deposits may be of Tertiary age. 42 Around Lake Eyre the tops of some of the higher hills may be composed of sandstones, etc., of Tertiary age. Reasons for not extending these Tertiary cappings far in a northerly direction are given later. LOWER CRETACEOUS. Mr. Brown regards the blue shale of the Lake Eyre artesian basin as Lower Cretaceous. Tate and Watt refer the same to Upper Cretaceous. The delimitation of the northern boundary is discussed in the following section. The writer includes in this section many of the tops of the hills lying north of Oodnadatta hitherto regarded as Tertiary. JURASSIC ( ?). The valleys of the Finke and Hale rivers, so far as at present known, furnish more evidence regarding the geological history of Central Australia than any other part. In 1897 Mr. H. Y. L. Brown, then Government Geologist in South Australia, published in a Parliamentary paper his revised reading of the several rock systems occurring there, viz. :— (1) Archean gneiss, granite, etc.; (2) Cambrian; (3) Lower Silurian; (4) Jurassic(?); (5) Lower Cretaceous; (6) Upper Cretaceous or Tertiary; (7) Recent and Tertiary. Their several equatorial extensions are delimitated in a section that accompanies the report. The report, and also the section, show clearly that Mr. Brown had altered his position in regard to one of the important rock formations, v7z., the Deep Well and Ooraminna sandstones. Formerly he classed these as Devonian (?), but herein they are, together with the Finke River sandstones, as seen between Horseshoe Bend and Goyder River, set down as Jurassic(?). To Mr. Brown belongs the credit of first noting that the Finke River sandstones dip south under the Cretaceous shales, and that they are ‘“‘intake’’ beds for the Lake Eyre artesian water supplies. The writer agrees with the extension of the Finke River sandstones northwards to Francis Well, but disagrees with the including | of the Deep Well and Ooraminna sandstones in that forma- tion for reasons set out hereafter. The Cretaceous shale for- mation is lithologically similar, from Lake Eyre to its northern boundary, a few miles north of Charlotte Waters Telegraph Station. As all observers are agreed on that point, further comment is unnecessary as to its northern margin. As to the age of the Finke River sandstones, Tate and Watt held that the Upper Cretaceous persisted as far north as Engoordina (Horseshoe Bend), and they mention _ Chambers Pillar as the most conspicuous outlier. The writer rejects Tate and Watt’s reading of this formation. They 43 appear not to have erasped the fact that the Finke River sandstones formation underlies the Cretaceous shales. Between Horseshoe Bend and Idracowra the Finke River sandstones lie conformably upon reddish and pale-coloured micaceous sandstone and shale beds. Near the contact the white and red bands alternate and show that the one passes into the other gradually, as belonging to the same formation. Good sections in evidence of this are plentiful, and the writer holds that both belong to one and the same formation. Mr. Brown separates the pink from the white, classing the former as Lower Silurian and the latter as Jurassic ( ?). - The writer’s reading of the Finke River sandstone, etc., is as follows:—In travelling from Oodnadatta north it is first seen on the slope to the Goyder River, from Mount Daniel. It is seen all the way to Horseshoe Bend except where hidden beneath the recent sand and alluvial deposits. At the latter place it reposes on the shale beds mentioned above. In follow- ing the Alice Springs road northward from Horseshoe Bend it is seen to continue to, and to form, the hills known as Percy Hills, even to the cappings. Thus far the formation is con- tinuous. Francis Well, which lies a couple of miles north of these hills, is sunk in red sandstone. A well on the south side of the hills is sunk in similar rock. Near Depot Well, and in other places along the Hugh River, bands of calcareous sandstone are seen in the cliffs. The sandstones are also seen to carry a large percentage of pebbles and boulders (mostly quartzite), e.g., between Depot Well and Alice Well. These pebbles belong to the Finke River sandstones formation and not to the wash of the Hugh River. Between Horseshoe Bend and Old Crown Point the pebbles are much in evidence ; they are seen at Yellow Cliff and all the way to the Goyder, and for a mile or two south of the Goyder Well. The sand- stone beds carrying them then pass under the Cretaceous shales, and they are not seen to the south of Mount Daniel. The Finke River sandstone, etc., it will thus be seen, is a continuous formation from Goyder Well to Francis Well; but north of Francis Well al! that remain are isolated flat-topped, or gently-inclined topped, hills scattered through the ranges. Examples of such occur a little north of Francis Well, as cappings on Ordovician (?) limestone; and again a little north of Breadens Dam. Three miles north of Ooraminna Water- hole, to the right of the road to Arltunga, a white sand- stone formation with siliceous limestone capping, horizontally bedded, runs for two or three miles, and perhaps for a greater distance, in a north-easterly direction. Also between Mount Undoolya and Emily Gap low hills of similar description are seen, and in and about the ranges in many places similar 44 hills are met with. They probably belong to the same forma- tion. The low hills of Ordovician age are readily distinguished from these. In travelling up the Finke River, from Horseshoe Bend, the Finke River sandstones are continuous to a spot a little north of Idracowra Station. One mile north-west of the homestead red sandstone flagstones form the north bank of the River Finke for half a mile or so. These flags probably represent an earher rock formation. A few miles farther north-west, again, similar flagstones are seen near the southern edge of the Ordovicians. It is here the Finke River sand- stones, etc., as a continuous formation, find their northern boundary on the Finke, but they occur as sporadic hills in the valleys, in and about the ranges, for many miles further to the north and north-west. These are of the same description as those already mentioned as occurring along the Alice Springs track.. Near Henbury Station a nest of these hills occurs. Between Horseshoe Bend and Idracowra the purple-shale beds belonging to this formation are much in evidence; their prominence is due to a low anticline having elevated the purple beds, the hills in places showing only a thin capping of white sandstone upon the purple shale, but they sink again near Idracowra. ‘These purple shales are the lowest visible beds in this formation. White sandstone beds follow in ascending order, then calcareous sandstone bands and pebble-bearing sandstones and thin bands of ironstone; then yellow and purple sandstones. These latter appear to mark the line between the Cretaceous shales and the Finke River sandstone series. About this horizon green glauconitic sandstones and shale bands succeed, in which J. J. East found Lingula subovalis. The included boulders and pebbles in the sandstone beds are very numerous and well-rounded, and principally com- posed of quartz and quartzite. They represent the harder rocks in the ranges to the north. The post-Ordovician con- glomerate beds, noted later, that flank the South MacDonnell probably furnished a large proportion of the pebbles. At Crown Point these pebbles and boulders form conglomerate beds in the sandstone varying from a few inches to several feet in thickness, and they occur on inclined planes and at varying angles of dip. The sandstone shows false-bedding, in a marked degree, also. The boulders occasionally are up to a couple of tons in weight. All are well waterworn. A good example of the way the conglomerate occurs in the sand- stone may be seen in the cliff and banks of a small creek where: the telegraph line drops on to Paddy’s Well plain, six miles north of Old.Crown Point Station. There the conglomerate 45 occurs running in a slanting band right up the cliff from bottom to top. Where these conglomerate bands form the tops of the hills, the tops and sides are covered with water- worn stones. Other observers have mentioned the occur- rence, but failed to note that the conglomerate bands in this Finke River sandstone were the source of the boulders and pebbles. They have nothing to do with the modern Finke River, as we now know it. The Finke River was not in existence when these conglomerate beds were formed, for they do not extend in that direction, so far as the writer is aware. They appear to have been brought by a swiftly-running river of pre-Cretaceous age, for these sandstone beds underlie the Cretaceous shale beds. Turbulent bedding characterizes the sandstone beds in which the conglomerate occurs. Tate and Watt came to the conclusion that these stones surrounded an imaginary lake that was held back by the table-topped hills at Cunningham Gorge, and that the lake-waters ultimately burst through the gorge and scattered the stones about. The absurdity of such an explanation makes one wonder whether they were serious in propounding such a theory. Later on Professor Tate set out the probability of the stones having been brought there through ice action. In the writer’s opinion the only thing not quite in accord with the ‘‘river’’ explana- tion is the presence of very large and intensely hard quartzite boulders, which, as before stated, are up to two tons in weight. But seeing that they may have been derived from the post- Ordovician conglomerate beds, a swiftly-running stream, such as the sandstones and conglomerate indicate, would meet the case. The writer has failed to find any grooves and scratch- ing on the boulders to suggest ice action, and the mode of occurrence does not suggest morainic material. From the comparative absence of conglomerate in these beds along the Finke route (contrasted with the abundance of the same along the Hugh route), one is led to the conclusion that the main drainage from the MacDonnell Ranges formerly came by way of the latter, viz., in pre-Cretaceous times, and that the course of the Finke River and Ellery Creek through the Krichauff (James) Ranges is of more recent development. The comparatively narrow Glen of Palms, Todd Glen, and others, ¢.g., lend some weight also to this supposition. Immense erosion, of course, has taken place since the Finke assumed the present course, for at its inception it flowed over the top of the Krichauff Ranges, gradually cutting its way down through the sandstones, quartzites, limestones, and shales of which that range is composed. Great erosion trans- pired in all the older series of rocks before the Finke River sandstones, etc., hereafter mentioned (following Brown) as 46 Jurassic (?), were laid down, for that formation is seen to occupy the eroded spaces. Subsequent erosion has almost completely removed the Jurassic (?) rocks from the highlands, sporadic remnants only remaining, affording evidence of the former dimensions of the formation. The remnants owe their existence, in the majority of cases, to hard cappings of quartzite, etc. When the Jurassic (?) strata were laid down the orographic features of the present Central Australian region, in a general way, were much the same as we find them to-day, subject, of course, to subsequent denudation. Erosion has now laid bare the older rocks on which the Jurassic (?) reposed, and to some extent cut deeper into them. The writer is of opinion that the Jurassic (?) formation was the last continuous formation laid down in that part of the continent. Many of the hills hitherto classed as Tertiary, and most of the so-called Tertiary cappings and outliers in and around the Central Australian ranges and north of Mount Daniel, have no existence as such. They belong to this Jurassic (?) formation. Chambers Pillar is a typical example. The last submergence beneath the sea was in Cretaceous times, and for this reason Tertiary strata, as a continuous formation, never existed there. A little rearranged material may form the tops of some of the flat-topped hills within the area under notice, which is often permeated with secondary silica, oxide of iron, etc., forming an enduring crust. No fossils have yet been found in this formation. Like the Cretaceous, this formation is seen to have undergone considerable erosion. Before erosion set in the formation was continuous through- out the ranges; it about half filled the valleys, and the older rocks stood out from it like islands above the sea. What movement has taken place in the ranges since the Jurassic (?) was laid down is impossible to say, but the slightly-inclined strata in the low hills occurring on the south side of the MacDonnell, east of Emily Gap, may or may not have been due to earth movements. Probably the old anta- clinal and synclinal folds have gradually yielded to pressure since the Jurassic (?) strata were formed. Between Idracowra and Horseshoe Bend is a long, low anticline; and six miles north of Crown Point evidences of earth movements are clearly apparent. At Horseshoe Bend, right where the station stands, the rocks are faulted. From these features it is evi- dent some earth movement has transpired since the beds were laid down. They are unconformable to the rocks on which they repose, but whether discordance occurs between them and the Cretaceous shales is unknown. The evidence afforded by the artesian bores south of Goyder Well leans in that direction. | 4 4 Post-Orpovicran. [DEvoNIAN (?).] In descending order, the next known rock formation is the post-Ordovician conglomerate and sandstones with pebble- beds that flank the Ordovicians on the south, as seen on the northern edge of the Missionaries Plain, in Rudall Creek, Finke Gorge, Ellery Creek Gorge, and in the ranges east of the latter. Tate and Watt found these beds to be not less than 7,000 ft. thick at Ellery Creek Gorge. Temple Bar Well, situated 12 miles south of Alice Springs, was sunk wholly in conglomerate identical in character with the above. Five miles south of Temple Bar Well, low hills of conglomerate occur along the road to Ooraminna. These hills extend for miles in a westerly direction. The writer regards these as belonging to the same formation. Sandhills and sandplains then cover the surface until at 20 miles from Alice Springs the red-and-white sandstone hills of the Ooraminna Range are crossed. These sandstones in places are lithologically similar to the Jurassic(?), but are seen to have been faulted and disturbed to a considerable extent, and moreover, as pre- viously mentioned, three miles north of Ooraminna Waterhole stands a hill of Jurassic(?) sandstone, reposing on this Ooraminna sandstone unconformably, and surrounding it as well. The strata of the latter is much disturbed, whereas in the former it is horizontally disposed and undisturbed. The unconformity is unmistakeable, and lithologically the two series are very distinct. At 32 miles south of Alice Springs is Indembo Well. This well was sunk 200 ft. deep wholly in conglomerate, identical in appearance with that at Temple Bar. Indembo Well outcrop of conglomerate is seen to ex- tend both east and west of the well; its thickness is unknown. The writer is of opinion that this conglomerate belongs to the same series of beds as seen at Temple Bar, Ellery Creek Gorge, and elsewhere, and it will thus be seen that it occurs both north and south of Ooraminna Range, but the intervening sandhills preclude the possibility of ascertaining its strati- graphical relationship to the Ooraminna sandstones with cer- tainty. The difficulty is increased by the extensive faulting that has taken place in the Ooraminna sandstones on both sides of the range. However, the writer’s opinion is that the conglomerate beds overlie the Ooraminna sandstone, and that, formerly, the conglomerate was continuous from well to well, its absence in places being due to erosion. The post-Ordovician conglomerate beds and the Oora- minna sandstone beds are both of some antiquity. Each par- ticipated in the disturbances that threw all the older sedimentary rock systems into anticlinal and synclinal folds. Tate and Watt observed that the post-Ordovician conglomerate 48 beds reposed upon conglomeratic sandstone beds. They, and others, have noted the occurrence of pebbles, sometimes in layers, in the ‘‘upper’’ red sandstone beds of the Krichauff and other similar ranges. The same beds, with included pebbles, form the bed of Ellery Creek between the Krichauff and MacDonnell Ranges. Tate and Watt failed to discover unconformity between this red sandstone series and the Ordovician sandstones, limestones, and quartzites on which the red sandstone reposes. They discovered Ordovician fossils in the boulders of the post-Ordovician conglomerate, and rightly deduced that they must be younger than Ordovician, but they included the upper red sandstone beds in their Ordovician, as they also did the Cambrian. Mr. Brown’s former reading of the Ooraminna sandstone—which is litho- logically very similar to Krichauff Range and Ellery Creek sandstone—was ‘“probably Devonian,” but in 1897 he included it in his Jurassic (?). The author’s reasons for separating the two are already stated. Where, then, are we to place the Missionary red sandstone beds? The post-Ordovician con- glomerate reposes upon them and gradually merges into them without any apparent unconformity. Probably they belong to one and the same formation, and pending further informa- tion the author suggests they be included in post-Ordovician. The discovery of a supposed cast of Zsoarca in the sandstone from Deep Well by Tate and Watt lends some little weight towards their classification, but the sandstones there do not resemble the Ellery Creek sandstone in any marked degree; its mode of weathering resembles the Ordovician sandstone. The discovery of annelide burrows in the Deep Well sand- stones, and also in the Ooraminna sandstones, by the author proves little one way or the other. These worm tracks are very common in the Ordovician quartzites. It is also possible that either the Ooraminna or Deep Well (or both) sandstones are older than the Missionary sandstones, notwithstanding any lithological similarity they may possess. Good sections of the Ordovician and Missionary (post-Ordovician) series are seen between Parkes Pass and Hermannsburg, on the Finke. The Ordovicians are there thrown into sharp folds; the post- Ordovicians are more gently inclined. The upper series, which le within the folds of the lower, are unfortunately worn back, and the actual contact is covered with sand and loam. ORDOVICIAN. The Ordovician system is well represented. in the MacDonnell and other ranges to the south. The rocks are composed of quartzites, sandstones, shales, limestones, etc., as seen in the South MacDonnell, in Gardiner Range, on the 49 Petermann Creek, and elsewhere. The limestones and quartzites in many places have furnished ample fossiliferous evidence to set the age of these beds at rest. The limestones, etc., forming the core of the Ooraminna Range are similar to those in the James Range, but in the latter brittle hard shales and conglomerate-quartzite and slaty bands are also much in evidence. Possibly, Cambrian strata may be repre- sented there as well, but until proven the whole may well be included in Ordovician. The Ordovician rocks are well developed in the South MacDonnell, where they form flanking ranges to the Cambrians and the granitic rocks of the central plateau. They dip off the Cambrians in a southerly direction at high angles, also vertically, and in one spot they are over- folded. The strike of the strata is east-west, and the post- Ordovicians repose upon them without any appreciable uncon- formity. Tate and Watt found 1° only of difference in their angles of dip. They form the core of what is locally known as the South MacDonnell, and also the ranges to the south, where, frequently, they are seen to stand vertically. They also dip north and south of the anticlinals at varying angles, and in places form gently-undulating beds which cover ex- tensive areas. They dip under the Jurassic (?) sandstones at Francis Well, on the Hugh, and also near Idracowra, on the Finke. They extend west and south-west of George Gill Range, and run well on towards Lake Amadeus. In short, this formation has a wide distribution throughout Central Australia, the extent of which is still undetermined. The author has not yet been able to satisfy himself that the red sandstone in which the Francis Well is sunk, and the sandstone composing Mount Charlotte—which is visible from the well—belong to the Jurassic(?) formation. The same difficulty presents itself a few miles north of Idracowra, on the Finke. There the red sandstone range to the west of the road also looks older than the Jurassic ( ?). The eruptive rocks have not intruded the Ordovicians so far as yet observed. In all probability many of the quartzite and shale cappings of the granitic hills, scattered over the plateau, north and also south-west of the MacDonnells, are Ordovician, and much of the so-called desert sandstone (e.g., at Glen Edith) belongs here as well. CAMBRIAN. The Cambrian quartzites, quartz-conglomerates, dolomitic limestones, sandstones, micaceous clay slates, shales, etc., so well represented in the MacDonnell Ranges, follow next in sequence, on which the Ordovicians repose unconformably. The Cambrians, in turn, rest upon the granitic rocks of the 50 Central Australian plateau. Quartzite-conglomerate fre- quently forms the lowest bed of the series, followed by quartzites, sandstones, dolomitic limestones, micaceous slates, shales, etc. The post-Ordovician, Ordovician, and the Cam- brian, together, form the flanking ranges on the south to the central plateau. The author has always held that these “anner’’ beds are Cambrian. Mr. Brown was of like opinion. Messrs. Tate and Watt, on the other hand, failed to separate them from, and included them in, their Ordovician group. They eliminated Cambrian strata altogether from the region, ‘“‘Oodnadatta to MacDonnell Ranges,’’ and claimed that the Ordovician succeeded the crystalline pre-Cambrians uncon- formably. The South MacDonnell forms one of the most conspicuous ranges in Central Australia. Looking north from the Hermannsburg Mission Station it presents a bold and striking appearance—bare masses of rock, rising in tiers to the north, culminating in dome-shaped hills and bluffs. Viewed from east or west a succession of sharp, high peaks and serrated ridges are seen. To the westward the ranges come to an end a few miles west of Mount Tate. They run eastward, also, in similar form as far as Alice Springs, a total of 150 miles, with an average breadth of eight to ten miles. The rocks dip south, between 15° and 90°, but the average is a steep dip throughout that distance. The higher ridges are quartzite and quartzose sandstone. The limestone and shaly beds, interstratified with the quartzites, have weathered away, and now form valleys through which we may travel, with high walls of rock on either side, almost the entire length of the ranges. The age of the beds making up this mountain mass is trifold, viz., on the south, post-Ordovician; the central portion, Ordovician; and the northern, Cambrian. From Alice Springs (Heavitree Gap), eastward, for 20 or 25 miles, the post-Ordovician and Ordovician strata are apparently absent—or, more probably, covered by alluvium— but beyond that distance they appear again and run on in un- diminished strength for many miles. The Cambrian strata, on the other hand, suffer no break, being continuous through- out. East of Alice Springs the ranges extend for 150 miles. The South MacDonnell Ranges are therefore not less than 300 miles long. The high quartzite ridge at Heavitree Gap runs east for 20 miles to Mount Undoolya; it then takes on a north-easterly course to and beyond Mount Benstead. It forms the most conspicuous and at the same time the highest part of the ranges, standing up 800 and 1,000 ft. above the plain—a bare wall of rock well above everything else. The dip is south, varying from 45° to 70°, and even steeper, in 51 places. On the north side are the granitic rocks of the plateau, on which the quartzite reposes. On the south this quartzite—which is sometimes conglomeratic—is backed up, apparently quite conformably, by massive dolomitic limestones, micaceous clay slates, shales, and thinner bands of limestone. Farther out (south) other quartzites, limestones, sandstones, shales, etc., occur. The former are seen to be much fractured, jointed, contorted, and displaced, and this is a feature of the Cambrians in contradistinction to ail other strata. Eastward from Mount Undoolya the dolomitic limestones spread them- selves out more than elsewhere, and continue so to Love Creek station. Earth movements and pressure have rendered it somewhat difficult to determine the actual contact line between the Cambrian and Ordovician; the greater dynamic and chemical effects upon the former, however, render a discrim- ination possible. The same causes have obliterated all trace of organic life except in most favourably-situated localities. Diligent search through many years failed to discover fossils in this formation, but in September, 1912, the author was fortunate enough to discover fossils in the dolomitic limestone which have since been determined by Mr. Walter Howchin, of the Adelaide University, to belong to the genus Cryptozoén. The spot where the discovery was first made is situated about half a mile west of the old Acacia Well, on the north side of the mail road from Alice Springs to Arltunga. Acacia Well lies about ten miles south-east from Mount Ben- stead and midway between that mount and Love Creek station. It is also about ten miles west of Bitter Springs. The fossiliferous strata form the northern boundary of one of those long narrow valleys of erosion, so characteristic of the South MacDonnell Ranges. The valley is about a mile wide. On the south it is bounded by a steep-sided massive reddish- coloured range composed of limestone, shale, sandstone, quartzite, etc., rising 600 to 800 ft. above the valley. The strike of all the rocks hereabouts is, roughly, east and west, and the (estimated) dip varies between 35° and 75° to the south. The valley here, and also for several miles both east and west, is bounded on the north by a dolomitic limestone range, 500 to 800 ft. high. The well is close to the range, and the road runs under the range quite close to the fossiliferous beds, which form the outer layers that run down and meet the alluvium that covers the floor of the valley. Some of the fossiliferous layers are only 2 and 3 inches thick, while others are massive, being yards through. The aggregated thickness is considerable—as seen where small creeks break across the strata—and there is no lack of material, though good speci- mens have to be searched for. The fossiliferous strata 52 maintain the same position in regard to the range and the alluvium for four miles in an easterly direction, and one mile westerly, from Acacia Well. All the fossils seen belonged to the same genus. Owing to the well having fallen in no water was obtainable within ten miles, hence the search was a rather hurried one. Eroded specimens occur on the slope. On bare patches of rock the fossils are plainly visible, and where the strata are broken across they are seen to penetrate the rock at right angles to the bedding planes, in much the same way that annelid burrows frequently do. The range is composed of hard blue and grey dolomitic crystalline lime. stone, in which the fossils occur, and the strata are less disturbed and less altered than elsewhere. The same dolomitic lmestone persists to the westward for over 150 miles; it also runs in an easterly direction for many miles. The east and west quartzite range, that forms the northern boundary of this dolomitic limestone, also forms the southern boundary of the granitic plateau and, as before stated, is the most striking physical feature in the MacDonnell Ranges. It supplies a number of the highest peaks, and many of the romantic-looking gorges, and, as a wall of rock, is probably unique. Mount Benstead is one of the peaks. The view from Acacia Well is one of steep-sided and rugged mountains in all directions. The ranges to the south are probably Ordovician. PRE-CAMBRIAN. The central plateau is, for the most part, composed of eneiss, schist, and granitic rocks, and hes north of Alice Springs. It is a ‘‘central boss’’ of wholly crystalline rocks, both igneous and sedimentary—principally the former. A feature is that, in places, the rocks have a definite and deter- minable dip, but the planes may be either those of stratification, cleavage, or foliation. 53 ON AN HEMIPTEROUS INSECT FROM AN AUSTRALIAN OPOSSUM’S NEST. By E. Bercrotu, M.D. (Communicated by A. M. Lea.) [Read April 2, 1914.]| Specimens of the species dealt with in this paper were- kindly communicated to me for determination by Professor K. C. Stirling, Director of the South Australian Public Museum. They were found under so interesting circumstances that the following report referring to their occurrence may be quoted from The Adelaide Observer of March 8, 1913 :— “In preparing opossums in as life-like surroundings as pos- sible for the new gallery, the Museum taxidermists found it desirable to procure a hollow limb, and obtained one near Adelaide. On sawing it off the limb was found to contain an opossum’s nest, with the opossum (Trichosurus vulpecula, Kerr) at home in it. On further examination the nest was found to be swarming with insect hfe. Among these were noted thousands of larve of a small moth; thousands of Acaride, or. mites, and Psocide, or book-lice; two kinds of tick, one a very peculiar sort; several interesting beetles, one of which is new to Science; and hundreds of a bug in all its stages. This last-named insect smells exactly like the bed- bug, but when matured is winged. It appears, however, to have the same unpleasant habits, as most of the larve and some of the mature specimens appeared to be gorged with blood. Seven pupz of two kinds of flies were obtained, and many unidentified larve; of these latter two are very curious, and they probably belong to one of the lace-winged flies, of which some extremely beautiful species are known in South Australia. It is hoped, therefore, to rear some of the larve. to the mature forms.” The bugs mentioned in the above notice proved to belong to a new species of the genus Clerada, Sign., of the family W/yodochide. Although the type of this genus is widely distributed both in the Old and the New World, nothing is known of the habits of it or of any other species of the genus, and only solitary specimens of them seem to have been taken. On the whole, very little is known of the food of the I/yodochide, and although most of them are supposed to be phytophagous, exceptions from this rule doubtless occur. It is quite possible that the new Clerada is a regular inhabitant of opossums’ nests, but, if so, I think this must be regarded as an acquired habit. The Clerada,. 54 no doubt, finds plenty of food in the opossum’s nest, but it is very unlikely that a member of this family draws blood from a warm-blooded animal. It is much more probable that it sucks out the Tineid and other soft-skinned larve so common in its haunt, unless it simply feeds on decaying vegetable matters in the nest. From the fact that the soft swollen abdomen of the larve is red in colour (like that of so many other Myodochid larve) and that the middle of the venter is often reddish in the imagines, it was hastily inferred that they were “gorged with blood.” CLERADA NIDICOLA, 0. sp. Black, above glabrous, both above and beneath very finely and thickly punctured ; basal border of pronotum and posterior angles of proplure tawny; the commissure, suture, and scutellar margin of the clavus also tawny, but very nar- rowly so; membrane greyish-fuscous; rostrum, orificia, middle of venter, and legs yellowish-ferruginous; trochanters black at tip; apex of femora and the whole tibiz somewhat infuscated ; antennz black or fuscous, last joint, except a narrow sub- basal ring, very pale testaceous. Head as long as pronotum and as broad as it is long, the postocular part rounded on the sides, ocelli almost touching the eyes, vertex more than twice broader than an eye; the eyes seen from above much longer than broad; rostrum reaching posterior margin of second ventral segment ; first joint of antenne scarcely passing apex of head, second joint three times longer than first, third a little longer than first, fourth half as long again as the third joint or somewhat longer. Pronotum at apex distinctly broader than the head and a little broader than its own median length, at base about one-half broader than at apex, transversely impressed before the middle, the impression more pronounced at the sides, lateral margins a little reflected, scarcely or very slightly sinuated. Scutellum in the basal half with a transverse impression, in the apical half with a longitudinal median keel. Hemelytra in the male very slightly passing apex of abdomen, in the female reaching base of dorsal genital segment, the claval commissure as long as the scu- tellum. Abdomen beneath with scattered hairs along the apical margin of the segments; male genital segment viewed from behind deeply arcuately sinuate, the apical margin somewhat angularly prominent in the middle, the claspers crossed, pale-ferruginous. First joint of hind tarsi distinctly longer than the two other joints together. Length: 3, 7 mame), 3 nam: South Australia (near Adelaide), in nest of Trichosurus vulpecula, Kerr. 55 This species is closely allied to C. laticollis, Horv., but is: distinguished from it by the much broader vertex. Dr. Horvath, who has kindly compared specimens of mdicola with the type of laticollis in the Budapest Museum, writes to me that /aticollis differs from the new species also in the following characters: —The upper side is still more finely and densely punctulate, the lateral margins of the pronotum are more distinctly reflexed, the orange-yellow basal border of the pro- notum is strongly dilated exteriorly and thereby the humeral angles are very broadly yellow, this colour being narrowly extended even along the lateral margins through three-fourths their length; and the legs are brownish, with only the coxe, trochanters (except their black tip), and tarsi yellow. There are also some minor differences in the mutual length of the antennal joints. Horvath also writes that the female specimen standing in the Vienna Museum under the name /aticollis may possibly, upon closer examination, prove to belong to nidicola. The colour of the larve of (. nidicola is fuscous-black, but the abdomen is red, with the two or three last dorsal segments in the middle greenish-testaceous in hue; only in the youngest larve the abdomen is, at least sometimes, en- tirely black. In the oldest larve the apical flaps of the hemelytral parts of the scuto-tegmen are testaceous. The antenne are brownish-testaceous, with the last joint (except a narrow basal ring) much paler. The legs are of a livid testaceous colour. The head is considerably longer than broad with much smaller eyes than in the imago and with no trace of ocelli even in the full-grown larve ; in the youngest larve the eyes scarcely project beyond the postocular margins of the head, and the distance between the eyes is eight times broader than an eye. Rostrum notably longer than in the imago, reaching or slightly passing the middle of the venter. Antennze constructed almost as in the imago, but in the youngest larve with the second joint comparatively shorter, being scarcely longer than the last joint. The larve before me belonging to the younger stages are in so poor condition that their other structural characters cannot be properly made out, but the two last stages show the following additional characters : — Fourth Stage.—Distance beween eyes six times broader than an eye. Pronotum three times broader than long in the middle, lateral margins narrowly reflexed, the transverse im- pression placed far behind the middle, anterior lobe more than three times longer than posterior lobe, with an impressed longitudinal median line not quite reaching the apical margin, and with a foveate impression on each side of the disk. Scutellum coalescent with the tegmina, but separated from 56 them by an obtuse impression, and with a more or less im- pressed, sometimes paler, longitudinal median line; tegmina divergent, reaching the first dorsal abdominal segment, rounded at apex, their exterior margin reflexed, the inner (apical) margin oblique, angularly sinuate somewhat outside the apex of the scutellum, clavus not separated from corium. Length, 4-4-4 mm. Fifth Stage.—Distance between eyes five times broader than an eye. Pronotum two times and a half broader than long in the middle, in other points as in the fourth stage. Scutellum as in the fourth stage; tegmina directed backwards, reaching a little beyond the base of the third dorsal abdominal segment, broadly rounded at apex, the inner (apical) margin parallel to the longitudinal axis of the body, arcuately sinuate somewhat outside apex of scutellum; structure of tegmina otherwise as in the fourth stage. Length, 5 mm. Of this genus eight species are now known, five of which occur in Australia. As Australian entomologists may find C’. ndicola or other species of the genus by examining opossum nests when opportunity arises, I think it useful to give a key to the Australian species with indications of the papers where complete descriptions of them can be found : — 1.

In this paper all the previously-described species from Australia are brought together, and two new genera and thirty-two new species are described, thus bringing the known ‘species of the subfamily in Australia to a total of forty-seven. Of the species described here, four were received from the South Australian Museum, the others being captured by Mr. A. A. Girault and myself in North Queensland. With one exception, I have not identified any male specimens. The magnification used throughout was 3-in. objective, l-in. optic, Bausch and Lomb. Table of Genera. Females.

Family CERAPHRONID A. The Ceraphronide have never been worked in Australia, and hitherto not one species has been recorded. In working up this family I was greatly surprised at the small number 86 of species found in all the genera except one, namely, the genus Ceraphron. The genus Ceraphron will now contain over forty Australian species, that number being nearly three-fourths of the total number of Australian species in the whole family. Of the species described herewith, twelve were received from the South Australian Museum, the remainder being taken by Mr. A. A. Girault and myself in North Queensland. Only one species, Aphanogmus braconis, Dodd, has been bred. The types are all in the collection of the South Australian Museum. The magnification used was 2-in. objective, 1-in. optic, Bausch and Lomb. Table of Genera of the family Ceraphromde. (1) Wings fully developed .

This genus is proposed to contain the species Humegas- pilus erythrothorax, Ashmead. In 1888 Ashmead erected the genus Humegaspilus to contain two species, 1’. canadensis, Ashmead, and H#. ottawensis, Ashmead. ‘These two species: were nothing but wingless species of the genus Conostigmus, Dahlbom, as Ashmead himself points out in 1893. Since the two mentioned species were the only ones in the genus, the genus must necessarily become a synonym of Conostigmus, Dahlbom. But in 1893 Ashmead gives another description of the genus, and places another species, /’. erythrothorax, Ash- mead, in it, at the same time eliminating the two previously described species from the genus. The genus, therefore, can- not hold, since it has already become a synonym of Cono- stigmus. The genus Conostigmoides is, therefore, erected with the type species, Conostigmoides (Humegaspilus ) erythrothorax, Ashmead. LAGYNODES FLAVUS, sp. nov. Q.

Lea, F.E.S., Museum Entomologist. [Contribution from the South Australian Museum. | [Read May 14, 1914.] PLATES Vi ro XT. The acquisition by the South Australian Museum of two fine new species of Dilochrosis rather forcibly directed my attention to the Cetonides, a subfamily of beetles considered by many entomologists to be the finest of all. I was pre- viously well aware of the chaotic condition of the Australian genera, which have never been considered as a whole, except by Kraatz; and his revision but added to the confusion. In 1880 Dr. Kraatz gave what purported to be a generic revision of the Australasian Cetonides. No doubt our species needed a certain amount of revision, but Kraatz used colour and markings to an unjustifiable extent, with the result that, if his characters were strictly adhered to, new genera would be required for varieties of well-known species. As an example, the diagnosis of his supposedly new genus Pheopharis ) contains the following particulars :—‘‘Antennze castanee. Thorax supra castaneus, disco macula magna lobata; ) basi apiceque nigris. Scutellum nigrum. LElytra castanea, basi humeris suturaque nigris. Pedes nigri, tibiis castaneis, apice nigris.’’ Speaking of the genera proposed by Kraatz, Blackburn said: 4) ‘‘Some of these latter are, I think, very unsatisfactorily characterized, and founded on slight characters, even colour being treated as generic.’’ Janson also ©) speaks of “‘the other numerous so-called genera as characterized”’ by Kraatz. . In preparing my notes on the subfamily I have probably had under examination much greater numbers of species and of specimens from Australia than have ever previously been gathered together. For this several Museums and private (1) Deutsche Ent. Zeit, pp. 177-214. (2) Founded on Dilochrosis brown. (3) This spot is sometimes absent. (4) Proc. Linn. Soc., N.S.W., 1898, p. 246. Gy Koe., 1889, parse: 133 collectors have to be thanked, in particular the National Museum, Melbourne, and Mr. C. French. I do not purpose giving here, however, a complete generic revision of our species, but where some are obviously out. of place to refer them to genera in which they would seem to be more at home. The list, therefore, simply gives particulars of the species that have been described or recorded from Aus- tralia, with an attempt at a better grouping than that by Kraatz, many of his genera of necessity being retained. References to species described or commented upon since the date of Masters’ Catalogue are given; but where noted in that catalogue, and not since referred to, the numbers there given are regarded as sufficient, and are noted in _ brackets. Where the species are unknown to me they have been left in the genera in which they appear in Masters’ Catalogue, unless specially commented upon. In his ‘‘Australian Insects,’’ pp. 160-162, Froggatt gives some notes on various members of the subfamily, but the species he refers to as Trichaulax marginipennis is evidently T. trichopyga. On pl. xvii. four species are figured. He also has given life histories of several species, references to these being noted in the list. Figures of the markings of many species are herewith given, mostly from South Australian collections, but often from specimens in the National Museum or in Mr. French’s collection. In Kraatz’s revision considerable attention was nearly always given to the pronotum; but, as a matter of fact, if Lomaptera (with its subgenera), Glycyphana, and Muicro- valgus are excluded, the sides and base are so similar in all the genera that they cannot be usefully employed. The sides are incurved near the apex, and again near the base, more noticeably on some forms than on others, but the differences are only of degree. Similarly with the base, the median sinus is sometimes deeper on some species than on others, and its proportion to the lateral ones varies; but the differences are only of degree. The scutellum also can seldom be use- fully employed. _ The dentition of the tibie is nearly always sexually vari- able, the female as a rule having more teeth than the male, this being especially the case with the front pair. To adopt many of Kraatz’s diagnoses would often mean referring the sexes or varieties of one species to two different genera. On the majority of species the pygidium is marked with concentric scratches or strige, usually leading up to a small median space. But on some specimens the scratches, whilst of the usual type, leave two small spaces, which then appear 134 like small granules. This appears to be due to individual variation; it is more common in Diaphonia and the alhed genera than in others. In the heavily-timbered parts of Australia many of our finest species appear to occur in abundance, but they are very seldom seen, as they frequent the tops of tall trees. Such collectors as the Dodd Brothers, H. Hacker, and the late H. Elgner, who have climbed trees and there waited, net in hand, have obtained many fine insects that the ordinary col- lector never sees. In this way they have obtained Lomapitera macrosticta and hackert, Chlorobapta tibialis, Dilochrosis: frenchi and balteata, Calodema plebejus, Metaxymorpha gloriosa and hauserz, and other magnificent day-flying beetles. The travelling collector, as a rule, obtains only the com- moner species that occur on flowering shrubs and dwarf trees; with an occasional good straggler. By felling trees in full bloom in fairly open country some of the rarer species may be taken occasionally. More than half the species known to occur in the vicinity of Sydney are to be taken on the flowers of Angopheora cordifolia. Whether, when collecting cn tall trees is easier than it is at present, many species will be taken in Tasmania is a question for the future; at present only one representative of the subfamily, a small J/ierovalqus, is known from there. In a group in which great variability is common, and often combined with rarity of specimens, it is only natural that extensive synonymy should result. Wallace’s remarks on the Malayan Cetonides are equally applicable to the Australian: ‘““The phenomena of variation are well exhibited here. . . . We have insects of wide range, and with such an amount of variation, that few would consider it possible that the extremes, considered alone, could be the same species ; but these extremes are united by a series of intermediate forms, many of which occur together in the same locality.” Probably all, or most, of our species will eventually be found to have varietal forms; but the three following lists of species normally, or occasionally, entirely black, may be of interest. Black species, sometimes with a metallic gloss. No varieties, differing in colour of upper-surface, as yet described : — Cacochroa pullata. Diaphonia frenchi (Schoch, not Lea). Metallesthes metallescens. Microvalgus mucronatus. M. mgrinus. (6) Trans. Ent. Soc., Wendoesvad cere iv. 135 M. squamiventris. Pseudoclithria fossor. P. maura. Tapinoschema lacunosa. Black species, with described colour varieties :— A blacopus ater. Cacochroa gymnopleura. Diaphona carolr. Pseudoclithria ruficorms.

D. «xanthopyga. Lomaptera hackert. Micropecila cincta. Microvalgus vagans. Pseudoclithria harticeps. Trichaulax philipsi. The Australian Cetonides are readily divisable into three main groups :— 1. Prothorax with a large medio-basal lobe covering, or almost covering, the scutellum. Lomaptera and subgenera of same. (7) 2. Prothorax without such a lobe, but base more or less distinctly trisinuate.(8) Mesosternum with a produced process of variable shape. All genera, except in 1 and 3.(9) 3. Prothorax with base rounded.

Lomaptera, and the other genera that have been proposed at its expense, are readily distinguished from all other Aus- tralian Cetonides by the median prothoracic lobe being pro- duced backwards so as to almost or entirely conceal the (7) Several genera, not all Australian, have been proposed at the expense of Lomaptera, and usually upon very slight grounds.

To the latter subgenus yorkiana and pulchripes are referred in the table, but they are not otherwise mentioned. At p. 151 Lomapteroides was proposed for duboulayt. Uh ACANTHOPYGA, Lea, n. sp. 2.

The type of Lyraphora was given as obliquata; the type of Platedelosis as bassu. The two supposed genera were widely separated by Kraatz, the firstnamed being placed in his first group having the ‘“‘mesosternal process narrow, greatly elongated and acuminate’’; the other in his second group having ‘‘mesosternal process wide, subdilated, apex acuminate or rounded:’’ As a matter of fact, in the female of obliquata the process (fig. 185) is much the same as in bassvw (fig. 186) ; in the male it is somewhat narrower, but it is quite distinctly wider than long, and to place the species in the first group is absurd. Both species have the clypeus of the same shape, club of antennz sexually variable in size, scapule large and pro- jected inwards between prothorax and elytra, abdomen of male somewhat flattened along middle but not grooved, and front tibiz of male armed at apex only. In the female of obliquata the front tibie of the male are tridentate, in the female of bassi they are bidentate; but this alone is not suffi- ‘clent to warrant their generic separation. 44. passi1, White (2585).

DiapHonta, Newman (including Chondropyga, Dysdiatheta, Dysectoda, Hemichnoodes, Melobastes, and Pocilocephata). I have been unable to see the original reference “2) to this - genus, but Burmeister 5) gives the typical species as the common dorsalis. Kraatz (4) also quotes dorsalis as the typical species. Kraatz and Thomson proposed many genera at its expense, and the majority of these on such trivial char- acters that they should not be maintained. Chondropyga. Noted under D. gulosa. Dysdiatheta. Noted under D. vicina. Hemichnoodes. Noted under D. mmiszechi. Melobastes. Noted under D. xanthopyga. Pecilocephala. There is absolutely nothing in the diagnosis of this genus by which it could be distinguished from Diaphonia. The antennal club of succinea is certainly smaller than in the males of dorsalis and some other species of the genus, and is practically alike in both sexes; but this also is the case with some other species of Diaphonia. Dysectoda. Kraatz proposed this genus for dispar, and doubtfully associated digglesi with it. But the latter is cer- tainly congeneric with impar, which was made the type of Tapinoschema by Thomson. As regards dispar, if this species was really from Queensland, as noted in Masters’ Cata- logue,“5) I probably have not seen it; but, if not, it. seems. (12) Loudon’s Mag. of Nat. Hist., n. ser., iv., 1840, p. 366. (13) Handb. der Ent., i1i., p. 586. (14) Deutsche Ent. Zeit., 1880, p. 199. (15) Burmeister, Kraatz, and Gemminger and Harold all give New Holland as the locality. 14] extremely probable that the species was the one subsequently described as satelles. The short descriptions of the sexes, as given by Burmeister, agree in every detail with many speci- mens of that species, and if satelles is a synonym of dispar, then the species is certainly congeneric with dorsalis. In any case, the genus Dysectoda does not appear to be required. Kraatz placed it in his first group of genera having the ‘‘meso- sternal process narrow, greatly elongated and acuminate.’’ Digglest certainly has the mesosternal process obtusely pointed, but it is neither narrow nor greatly elongated ; impar has the process a little shorter and more rounded, but it cer- tainly is congeneric with digglesi, and Kraatz left the former in Diaphonia. Micropecila. The tibie tridentate in both sexes and longer than the tarsi are the only features in the generic diagnosis that, in conjunction, seem divergent from Diaphoma. The mesosternal process is obtusely pointed in cincta, but then it is scarcely alike on any two species of Diaphoma. It is certainly a very weak genus, but OEE eT on the whole, may be allowed to remain. Tapinoschema. Noted under genus. * 58. CAROLI, Lea, new name. Q. wrencne. lea, a. pr., Proc. Linn.

By Kraatz that species was referred to Diaphonia. It. certainly has but slight grounds for generic rank apart from Diaphonia, but may be associated with Diaphona digglest (Dysectoda of Kraatz) and Diaphoma lacunosa (Metallesthes of Kraatz). These three species agree in having a short robust form with coarse elytral punctures in numerous irregular series. The head and mesosternal process are similar, but the tibiz are somewhat variable. That they belong to but one genus seems certain, and for the present, at any rate, they may be left in Tapinoschema. 81. pIGGLEsI, Janson (2551). Q. 82. impaR, Macl. (2600). Q. 83.

This species is a common one about Cairns and elsewhere in Northern Queensland, and may be readily distinguished from the other Australian green species by two characters in combination, v2z. :-— 1. A strong transverse ridge (almost a carina) across the pygidium. 2. Elytra with transverse strigz on the sides from near the middle to near the apex, then directed across, by way of the preapical callosities, to near the suture; but the apical slopes and the discs entirely without strige. The teeth of the front tibie are somewhat variable, the hind one being sometimes very feeble. The black tubercle on the shoulder, mentioned by Janson, appears to be due more to handling of the specimens than to any other cause, and on good specimens the black is either altogether absent or is just traceable. An occasional specimen in certain lights appears almost purplish, or something like shot-silk. The male is rather narrower than the female, and has the four 145 median segments of abdomen conspicuously impressed along the middle. There are in the South Australian Museum the type female and a co-type male of bourkez,(2) and these agree per- fectly with Janson’s description of yorkiana; the latter name has precedence. LoOMAPTERA PYGMHA, Kraatz. A few years ago Mr. Hacker took numerous specimens of a small species of Lomaptera at the Coen River. Some of these were compared and agreed with specimens in the Macleay Museum from New Guinea, standing under the name of pygmea. Recently Mr. W. D. Dodd took six specimens of the species at the Coen River, and these agree with the original description, except that the size is smaller (155-19 mm. as against 19-21 mm.) and that the entire legs, instead of appar- ently the femora only, are of metallic-red. In general appearance it is like pulchripes, except that it is smaller and more metallic, but the clypeus is more deeply cleft and the scutellar lobe is rounded at the tip, concealing the scutellum. LOMAPTERA WALLISIANA, Thoms. This species was originally recorded as from Wallis Island, but Wallace records it from Cape York from a speci- men in Major Parry’s collection. Janson compared it with yorkiana, from which he stated it differs in the prothorax regularly rounded at the sides from the base. I have seen several species labelled as wallsiana and wallisiana, but they usually belonged to yorkiana. LOMAPTERA PULCHRIPES, Thoms. A common insect in Northern Queensland, although in Masters’ Catalogue only recorded from Fitzroy Island. The male has a rather wide depression along the middle of the second and third abdominal segments, but traceable on to the preceding and following ones. A male in the National Museum is larger (25 mm.) and rather broader than usual, and has the pygidium of a beautiful golden-red. Another male in the National Museum (from the Endeavour River) is of a most beautiful golden-green, both above and below, with the legs and pygidium of a beautiful purplish- bronze. Each of its front tibie has the two terminal teeth of normal length, but the following one (in the middle of the outer edge) is greatly reduced in size, appearing little more than a slight swelling. (20) It 1s from these that the figures of the tibize were drawn. 146 LOMAPTERA DUBOULAYI, Thoms. ava nti. 19: In this species the prothorax and elytra usually have a complete flavous border, narrower at apex of prothorax, and wider at apex of elytra than elsewhere. Frequently near the apex of prothorax a small spot extends inwards on each side, and occasionally a vague spot may be traced on each shoulder. In the National Museum there are two females, from Cape York and Endeavour River, that have no flavous border to the prothorax. The elytra also at first appear to be without such a border, but on a close examination the sides are seen to be obscurely diluted with red. LOMAPTERA CINNAMOMEA, Thoms. BY yallay cise a0 adele This species varies from a form with the prothorax immaculate to one with a wide M in the middle of same, but the common form has three disconnected spots, of which the middle one is longer than the others (as on the type). Sometimes there is also a vague spot towards each side at the apical third. The female differs from the male in being wider, elytra less narrowed posteriorly, pygidium more pointed, abdomen evenly convex along middle, and front tibiz with an obtuse tooth near apex, in addition to the terminal tooth. LOMAPTERA DEYROLLEI, Thoms. This species was described as being entirely of a clear olivaceous-green; but Schoch, in redescribing it, says it resembles lucovoraz \21) in the blackened anterior edging of the elytra, and, again, ‘‘elytra darker and duller-green with blackened anterior edge, but not so wide and intense as in lucivoraz.’’'22) Thomson did not mention the tibial dentition, but Schoch described the front tibiz of the male as bidentate. The shape of the pygidium was mentioned by neither. It appears possible that Thomson really had two species before him. At the time he described deyrolle:, he men- tioned having four specimens,:and quite possibly the type belonged to australis, and the specimen described by Schoch to a form of yorkiana with elytra darker at the base than usual. Thomson described the elytra as ‘“‘basi levia deinde punctato-striolata, striolis transversis,’’ characters which (21) A Papuan species. (22) Translation by Mr. F. R. Zietz. 147 would appear to exclude it from yorkiana, but which agree with australis, as, in fact, does the whole of his description. On the other hand, Schoch described the elytra as being trans- versely scratched at the sides and posteriorly, and the anterior tibiz of the male as bidentate, characters which exclude it from australis, but render it probable that the specimen he described really belongs to yorkiana. There is, of course, the possibility that the type of deyrolle: really belongs to neither australis nor yorkiana; but the quoted extracts render it quite evident that the specimens described as deyrollet by Thomson and oe belong to two distinct species. LOMAPTERA AUSTRALIS, Wallace. Ply sont ties 161, 162. The description of this species, of which only the male was known to Wallace, is rather short and somewhat unsatis- factory. I have seen the name attached to several green species, but am fairly confident that five males (from Cape York, Coen River, Cairns, and Darnley Island) and a female (from the Coen River) belong to the species.'23) These speci- mens are much the same in size and colour as yorkiana, but differ in having the pygidium subconical, instead of trans- versely keeled, and the elytra with transverse scratches over most of their surface only, agreeing well with ‘‘elytra finely transversely striate, the base smooth.’’ They range in length from 114-133 lines (the types were 13-15 lines). The front tibiz were described as ‘‘inermibus,’’ and, again, as having the “‘outer edge quite smooth.’’ But probably the apical tooth was regarded as a spur. The female differs from the male in having the elytra less narrowed posteriorly, the pygidium compressed on each side (so that it appears almost keeled longitudinally), abdomen strongly convex along middle, and front tibie obtusely dentate near apex. The species appears to be the same as the one subsequently named prasina, from Aru, and still later as wnitatriz, from Darnley Island; the latter has already been noted as a synonym of the former. LOMAPTERA HACKERI, Lea. Plo vais fie: 14: In a long series of this species recently taken at the Coen River by Mr. W. D. Dodd, about one-fourth of the (23) Mr. W. D. Dodd has recently taken it in abundance at the Coen River. 148 specimens have the elytra entirely dark, and in many others the red markings are just traceable. LOMAPTERA MACROSTICTA, Lea, Pi vii), fos! 12) 93. Twelve specimens recently taken by Mr. W. D. Dodd at the Coen River all have the large spot entire, as in fig. 13, but I have seen several resembling fig. 12. LOMAPTERA ACANTHOPYGA, Nl. Sp. Pl. vi., fig. 1. @. Metallic coppery-green, portion of clypeus, lateral and basal margins of prothorax (narrowly), about cne-third of elytra at apex, pygidium, tibie, tarsi, antenne, and palpi more or less castaneous, with a faint greenish gloss. Head with small, scattered punctures, becoming denser on clypeus ; the latter deeply cleft. Prothorazx feebly decreas- ing in width from base to beyond the middle, and then strongly narrowed to apex; disc with small, scattered punctures, becoming denser towards and strigose on sides; scutellar lobe somewhat obtuse at tip, just leaving the tip of scutellum exposed. Hlytra not much wider than prothorax, post- humeral incurvature rather strong, sides diminishing in width to apex; rather densely transversely strigose, except at basal fourth, where there are a few small punctures only. Pygidiwm acutely produced in middle, longitudinally foveate on each side of base, densely concentrically strigose. Front tibie sinuous on external edge, the apex strongly dentate. Length, 22 mm. Hab.—Queensland: Johnstone River. Type in C. French’s collection. Readily distinguished from all previously described Aus- tralian species by the partly castaneous elytra and appendages and acutely pointed pygidium. Its nearest Australian ally is duboulayi, but the pygidium is very different to that of the female of that species. The two shades of colour on the elytra gradually merge into each other. HEMIPHARIS INSULARIS, Gory et Perch. Described originally as from Melville Island, but a com- mon species in the Northern Territory and Queensland. Specimens vary in size from 17 to 26 mm.,(@4) and in colour (24) The only specimen I have ever seen less than 20 mm. is ne 17 mm., and is in the National Museum from the Endeavour iver. . ay 149 from olivaceous-green to bright golden-green. In the Black- burn collection there were two specimens from North-West. Australia placed as belonging to the species without comment, and they agree with the description of speciosa, which ap- pears to be simply a variety. All the rather numerous speci- mens that I have seen from North-West Australia have a brighter colour than those from the other parts of Australia. Numerous specimens from Tennant Creek (taken by Mr. J. F. Field) are intermediate in appearance. /roggatt: appears: to have been described from a male of speciosa. The form described as olivacea is quite the common Northern Territory form of the species. A specimen from Darwin has the elytra (except the suture, which is green) and abdomen of a distinct bluish- purple, strongly at variance in colour with all the other specimens that are before me. A second specimen, however, has the elytra slightly tinged with purple, although when viewed from behind the purple tinge is more evident. The punctures and lateral scratches vary to a certain extent. The male is considerably narrower than the female, consequently more strongly convex, and its pygidium is much less trans- verse, with its lower edge slightly more produced. DILOCHROSIS BROUNI, Kirby. Pl, wit.; figs. 15; 16,, 17. This species should never have been generically separated from Dilochrosis atripennis, and to make it the type of a new genus (Pheopharis) largely on account of colours (even using a prothoracic spot that is not always present) is reducing generic distinctions to an absurdity. Only that Australian species have been catalogued in accordance with Kraatz’s. ideas, it would be better to regard his treatise as non-existent. The prothoracic spot, when present, is generally fairly large, but I have never seen it of exactly the same shape on any two specimens. Sometimes it is split up into two, some- times it is represented by two small vague spots, and not in- frequently it is entirely absent. Generally there are two or three small lateral spots slightly in advance of the middle. A female in the National Museum, evidently belonging to this species, is of a very dark brown, so dark that the black markings are very ill-defined. It is covered all over (except on the black parts) with minute granular elevations, giving the surface an appearance as if covered with very fine dew. To the naked eye the granules are not distinct, but, when present, they cause the surface to appear less polished than the other parts. This curious appearance was probably due 150 - to the specimen having been in some way injured before maturity. In all other structural details it agrees absolutely with normal females. DILOCHROSIS ATRIPENNIS, Macl. var. castanea, Janson. The typical form of this species has the elytra of a very dark-brown, almost black; but the species varies to a form in which the only dark parts are some faint infuscations at the base of prothorax and elytra, and a vague spot on each side of the former. The commonest form is one in which the head and scutellum are blackish, and there is a distinct spot on each shoulder. This form has been named castanea. (25) Mr. Janson stated that castanea could be distinguished from atripennis by “‘the four posterior tibize of the female being armed externally with an acute tooth in the middle.”’ But all the females of atrzpennis now before me are so armed, and the males have these tibize unarmed in the middle. The Species varies from 30 to 40 mm. in length, and is widely distributed in the tropical parts of Australia, although apparently nowhere common. DILOCHROSIS TORRIDA, Janson. There are before me two specimens from Western Aus- tralia (Beverley and King Sound) that I have long had under the name of torrida. They are entirely castaneous on the upper-surface, with the exception of a slight infuscation at the base of the prothorax and the elytral suture. The upper- surface has not the high polish that is usual in Delochrosis ; but there are many other specimens of the subfamily in which the degree of polish varies very considerably, and is probably due to a certain extent to immersion in spirits or other liquids, or to other causes. These specimens have the four hind tibiz each armed at the middle with a sharp spine, and as the abdomen is evenly convex along the middle they are certainly females. But the type was described as having the four hind tibie simple externally and the sign “‘Q”’ was used for it; possibly, however, in error. The two specimens under examination vary somewhat in comparative widths, in the colour of the under-surface and punctures of the abdomen, but I believe them to represent an extreme form of aétrz- pennis, and think it probable that the name torrida should be regarded as a varietal one. (25) Reference to the figure of castanea (Cist. Ent., i., pl. vi., fig. 1) was omitted from Masters’ Catalogue. 151 DILOCHROSIS BALTEATA, Vollenh. Pl. xii., fig. 115. Fair numbers of this handsome insect have recently beem taken from Cairns to the Coen River, in North Queensland. DILOCHROSIS BAKEWELLI, White. Pl. vii., fig. 18. This species, a very rare one in collections, extends from Melbourne to Brisbane. DILOCHROSIS SUBFOVEATA, Thoms. The description of this insect is a rather curious one, as the head and prothorax are described as being ‘‘subsurdus’’ (somewhat deaf), and the elytra as being ‘‘foveis 4 vagis ornata,’’ apparently spots being meant, as in comparing the species with brownz “‘quatre taches noires’’ are mentioned. DILOCHROSIS FRENCHI, Blackb. The type of this species is in the National Museum, and by the courtesy of Mr. Kershaw I have been able to examine it. It is certainly a male, as presumed by the late Rev. T. Blackburn. On its eyltra across the middle there is a dis- tinct depression, and there is a less distinct one a short dis- tance behind the middle. These depressions were not men- tioned in the original description, and may have been con- sidered accidental, but they are alike on four other specimens. under examination. The female differs from the male in having the sides of the clypeus rounded instead of parallel-sided, and less turned up at the apex; the elytra less narrowed posteriorly ; abdomen evenly convex along middle; front tibiz strongly and acutely. tridentate, and the other tibie each with an acute median tooth. In the female the apex of the clypeus is very feebly incuryed to the middle, and in the male it is straight. All other species of the genus have the clypeus deeply cleft. Specimens have been taken on tops of tall trees at Kuranda on several occasions by the sons of Mr. F. P. Dodd. DILOCHROSIS RUFOLATERA, 0. Sp. PEs) fie. 2. @.

Clypeus with punctures as on head, widely depressed towards apex, the sides not separately elevated, apex moderately notched, with the tips rounded, sides rounded. Prothorax with sides narrowly margined, 152 median sinus deep, about two-thirds the width of each of the lateral ones; with dense and very minute punctures, and with fairly numerous large ones, but still small, becoming larger towards the sides.

Allied to bakewelli, but differs from female of that species in being somewhat narrower, with the elytra and pygidium entirely black, the former with more conspicuous rows of punctures and apex less acutely bimucronate, prothorax with a much smaller portion of the sides red (the red much the colour of the elytral fascia of balteata), and front tibiz more obtusely tridentate. The greatest width of the red margins is slightly in advance of the middle, where it is almost the width of the scutellum, but it is narrowed to apex, and does not quite extend to the base. The hind coxe are vaguely diluted with red. The type was obtained floating on a tub of water at Malanda. DILOCHROSIS WALTERI, 0. sp. Le Nie EI ASS TONE atte enateay chY). 3. Flavous, shining; sides of base of head, tips of ‘clypeus, prothorax narrowly at base and narrowly at middle of apex, two longitudinal vitte, elytra at sides of scutellum, suture, a spot on the shoulder, and an elongated one near the apex of each elytron, most of the sutures of under-surface, knees, tibial spurs, and teeth, and the tarsi black or blackish ; antennz and palpi more or less reddish. Head with rather dense, small punctures, except on a transverse shining line near base. Clypeus with somewhat coarser punctures than on head; apex deeply notched, with the tips acute, with a sublateral ridge from base to apex.

Hab.—North-West Australia. Fortescue River, near Hammersley Range (Walter D. Dodd). Type, I. 1495, in South Australian Museum. : Very distinct from all previously described species. In its spotted elytra it apparently resembles swbfoveata, but. that species is described as having the head and scutellum black, and prothorax with a single narrow fascia. The pro- thoracic vittze are sometimes feebly interrupted in the middle, and may extend to the base or may not touch it. There are generally two infuscate spots on the clypeus, and there is: occasionally one on the pygidium. P@CILOPHARIS EMILIA, White. This species was described originally as from the New Hebrides and as a Schizorrhina, but it seems to be fairly common about Cairns and elsewhere in Northern Queensland. The markings on the elytra are subject to considerable: variation. The scutellum may be entirely yellowish, or with a median line occupying half or more of the surface. The- pygidium may have two or four spots. EUPGCILA AUSTRALASIZ, Don. Pl, var, fies: 20, 21. This species is abundant in many of the coastal districts of New South Wales and Queensland,(25) but is rare in Vic- toria, South Australia, and the Northern Territory. When specimens are alive their markings are of a vivid green, but after being placed in alcohol these become yellow or (26) Queensland specimens are usually smaller than those from. New South Wales. 154 greenish-yellow. Even if killed in other ways the green usually changes, unless the internal parts are quickly removed. The species is commonly called the ‘‘Horseshoe Beetle’’ or ‘‘Fiddler Beetle,’’ on account of the markings. These are singularly constant; slight variations of detail as regards the vitte occur, but I have seen no specimens of the species that could not be confidently identified at a glance. But the only specimen that I have seen from the Northern Territory has the median prothoracic vitta reduced to a small indistinct spot, and the transverse basal mark to two small disconnected spots. On the female there is an angular black spot in the middle of the pygidium, connected with the base by a short black line. On the male there are two spots connected with the lower edge of the pygidium; but separated internally, with a median black vitta extending from the base to about the middle. ; var: intricata; nN. var. Pl. vii., fig. 22. A female in Mr. French’s collection, from North Queens- land, is labelled ‘‘Schiz. panzert, Swartz, or sp. nov.,’’ in the late Rev. T. Blackburn’s writing. This was, no doubt, a guess on his part, as he had not seen the description of panzert. In Masters’ Catalogue panzerz is given as a synonym of australasie, and the description, except for the base of the prothorax, agrees quite well with ordinary specimens of the ‘species, whose markings have faded from green to flavous. Of the basal markings Swartz says “‘‘ante basin linea trans- versa sinuata flava (subinde interrupta)’’; whereas on normal specimens the basal marking is usually continuous and con- nects with the lateral ones. On Mr. French’s specimen, however, there is a discon- nected curved mark on each side of the base, and on each elytron there is a narrow vitta on each side of the suture, commencing just before the tip of the scutellum, and ter- minating some distance before the postmedian fascia. In all structural details, however, it agrees with normal females, so it does not appear desirable to give it more than a varietal name. EUPG@CILA EVANESCENS, Nn. sp. Pl. vi., fig. 4; pl. xiii., fig. 183. Q@. Black; pale markings as follows:—Clypeus (except for the tips and a short line connected with each of same) ; sides (the extreme outer base black) and apex (but not the extreme apex) of prothorax (but with a small dark spot on each side) ; a median line on scutellum; a curved line on each elytron from the base to basal third, a small spot half-way 155 from near apex of same and suture, an interrupted post- median fascia (or transverse row of spots); a large transverse spot on each side of pygidium, and the tip of same; a fascia across each abdominal segment (on the second and third interrupted in middle) except the apical one, which has a small spot on each side; metasternum except the middle and sutures, parts of meso- and of prosternum; parts of front and of hind cox, lower edge of femora, upper edge of the hind pair, and a subapical spot on the upper edge of each of the others. Head with rather small irregularly distributed punc- tures. Clypeus rather strongly notched in front, tips and sides rounded; punctures rather denser and coarser than on head. Club somewhat shorter than clypeus. Prothorax with the margins lightly sinuous and rather strongly decreas- ing in width from base to apex ; medio-basal sinus fairly deep, about half the width of each of the others; sides and apex with a few small punctures, elsewhere almost impunctate. Scutellum with a few small punctures. Hlytra not much wider than prothorax, but shoulders rather strongly bent downwards, posthumeral incurvature strong, suture raised posteriorly but flat near base, with a few small scattered punctures, but some fairly coarse ones on the margins near apex. Pygidiwm strongly transverse, transversely or obliquely strigose. Mesosternal process strongly produced and acute. Front tibce@ strongly tridentate, the hind ones with a sub- median transverse ridge. Length, 21 mm. Hab.—Queensland: Bowen. Type in National Museum from F. H. duBoulay. Rather larger than the female of australasie, prothorax without median and basal markings, elytra without apical markings, the postmedian fascia and the basal vitte different, the mesosternal process longer and more acute, and the tibiz- somewhat different. The pale markings of the type are now of a rather dingy-flavous, but in places with remnants of green; on the living specimen, however, they were probably of a bright-green. EUP@CILA MISKINI, Janson. Janson’s figure (27 of this species shows an insect some- what like australasie, but with markings certainly different. The elytral markings approach those of Chlorobapta besti and tibialis, but as the mesosternal process 1s described as: “long, pointed, and slightly incurved at its apex,’’ it is quite: certainly not a Chlorobapta. (27) Cist. Ent., ii., pl. i., fig. 5 (not 4, as quoted in Masters’ Catalogue). 156 EUPG@CILA INSCRIPTA, Janson. Pitwia.. figs, 23 and) 24! Living specimens of this species are of a beautiful pale- green colour, but after immersion in alcohol the green changes to yellowish-green (as the type was described to be), and finally to brownish-yellow. The markings are variable, but the reversed W (28) on the prothorax appears to be always ‘conspicuous. The pygidium usually has three black spots on the male, but sometimes the median one is absent. On the female only the median spot is present. CHLOROBAPTA FRONTALIS, Don. Pl. viii., figs: 29 to 40. This common and widely distributed species is the most variable of all the Australian Cetonides. In length it ranges from 17 to 26 mm. The markings are indifferently green, greenish-yellow, or yellow, but probably on living specimens they are nearly always green. Many specimens have mark- ings somewhat like those of Hupecila australasie, but that ‘species has the mesosternal process acute. The description of viridisignata would indicate that it is ‘quite an ordinary variety of the species. It is true that Macleay made no mention of prothoracic markings, but these are often so small and obscure that they could be easily over- looked. The form described as jansont appears to represent almost, but not quite, the extreme end on the dark side. A ‘specimen, labelled by the late Rev. T. Blackburn as jansoni, agrees well with the description, except that it has no spots on the pygidium; but these are frequently absent, even on ‘Specimens with quite extended markings. The spots were described as bright-yellow, and they are bright-yellow on the specimen under examination. There are two specimens of this variety in the National Museum, also without spots on the pygidium. One has been in Mr. French’s collection, and is labelled as from the Salt River in the late Mr. A. S. Olliff’s writing. The pale markings attain their maximum on a specimen (fig. 30) in the National Museum, on whose right elytron all are connected, with the exception of the posthumeral spot. ‘On the variety jansoni (fig. 40) all the markings on the upper- ‘surface have disappeared, with the exception of a small spot on each elytron. And on two specimens before me the upper- ‘surface is entirely dark; one of these was labelled as frontalis (28) In North-Western Australia the species is QED) referred to as the W-beetle. 157 by the late Rev. T. Blackburn. Not all the varieties before me are here figured; indeed, to do this would mean that almost every specimen would have to be done, but the selection given sufficiently indicates the great variability of the species. The markings are sometimes different on the different sides of an individual. The markings on the head, pygidium, under-surface, and legs are also extremely variable. The markings on the female are usually less in area than on the male, and her head, scutellum, pygidium, and abdomen are not uncommonly entirely black. CHLOROBAPTA BESTI, Westw. Pl. ix., figs. 52 and 53. A species apparently confined to Victoria and _ the southern parts of New South Wales. The markings are some- times almost identical with those of tzbzalis, but the hind tibiz of the male are utterly different to those of that species. CHLOROBAPTA TIBIALIS, Lea. tibialis, Moser. This species was described by myself in 1911. In the following year it was described under the same name by Herr J. Moser. The female differs from the male in being somewhat stouter, less of the head and under-surface green, each of the spots on the pygidium without a median black spot, abdomen evenly convex along middle, front tibia more acutely tridentate, middle tibie thinner, with an acute median tooth, claws of middle tarsi of even size and shape, hind tibie thinner, much less hairy, not dentate on lower-surface, but with an acute median outer tooth, and apex acutely dentate and bispinose. The female is rather wider than the female of bestz, the prothorax more transverse with somewhat smaller punctures, the markings of a much brighter shade of green, and the mesosternal process considerably larger. & CHLOROBAPTA HIRTIPES, Nn. sp. Pi: V1., fig: 5. 3d. Black, with dark-green markings. Under-surface in parts with moderately long hair; hind tibie with a con- spicuous fringe of long black hair on one side, and on the other a fascicle at base and another at apex. — Head constricted behind eyes, with dense and fairly coarse punctures between eyes, becoming smaller on neck. Clypeus about as long as wide, a depression towards each 158 side, the sides themselves and the apex somewhat raised and thickened, apex feebly incurved to middle; punctures sparser than between eyes. Club as long as clypeus is wide. Pro- thorax not much wider than long, basal half almost parallel- sided, thence oblique to apex; medio-basal sinus fairly deep, about two-thirds the width of each of the others; with small scattered punctures, becoming larger on sides. Scwtellum with a few punctures about base. Hlytra considerably wider than prothorax, posthumeral incurvature strong, sutural stria. deep; each elytron with four irregular rows of punctures and some irregular ones on sides, the second and third rows within a shallow depression. Pygidium very obtusely pointed, rather lightly concentrically strigose. Abdomen feebly depressed along middle. Front tzbie tridentate; middle ones stout, apex bidentate and unispinose; hind ones stout, some- what curved, apex produced on one side, but neither dentate nor spinose, claws of middle tarsi of unequal shapes. Length,. 24 mm. Hab.—New South Wales: Richmond River. Type in National Museum from F. H. duBoulay. Allied to trbzalis and bestz, and with middle tarsi much as in those species, but readily distinguished by the apex of the hind tibiz. In the male of besti, as also of frontalis, the hind tibia is scarcely continued beyond the insertion of the tarsus, and is armed with two strong spurs; in tzbialis there are no spurs, but the apex is much more acutely produced, near the base also the tibia is much stouter and is strongly armed. In the present species there are no spurs at the in- sertion of the tarsus, but the apex is continued as a flange beyond the same; from some directions it appears as if the tibia had been split down the middle to the tarsus, and then one-half snapped off. With the tarsus continuing the line of the tibia, however, this appearance would be partially concealed. The mesosternal process is not quite as obtuse at the apex as in best: or tibzalis, but much less sharp than in EBupecila australasie. On the type there is a fairly wide green space across the base of the clypeus; the greater por- tion of the elytra is green, with the suture and sides, a dilated portion of the sutural marking close to the scutellum, a postmedian quadrangular space attached to the suture, an irregular preapical fascia, and the shoulders black; the pygidium is green with a spot on each side, the apex and a median line black, the lateral edges of the hind coxe and part of the sides of the mesosternum are green; as is also a: line across the penultimate segment of abdomen.

This species is very variable both sexually and individu- ally ; and Victorian specimens, as a rule, are larger than those from Queensland. The male has very peculiar hind legs (fig. 158), utterly different to those of any other Australian Cetonid. His front tarsi also have a fringe of long and curious hairs, but it is much more pronounced on some specimens than on others. The hind tibie have a tooth at the base, but it varies con- siderably in size and acuteness. The clothing of the upper- surface is also denser on the male than on the female. One female has the upper-surface almost glabrous, but this may be due to abrasion. The prothorax of the type had two black vitte, and several such specimens are before me, in others the vittze are con- joined, and on others the pale markings are represented by small, pale, isolated spots. On the elytra there are usually six black spots, usually connected with the suture, which itself is black; there is also a spot on each shoulder, but these are sometimes conjoined to the subbasal ones. The pygidium is dark on each side, and sometimes along part of the middle as well. The female is usually larger than the male and frequently has the prothorax entirely black, but. that segment is also sometimes bivittate, or with disconnected pale spots. The scutellum is sometimes entirely black, but often has a pale spot. The elytral spots are usually considerably larger than on the male, and are sometimes so extended that they cover much more of the surface than the pale portions; these, on one Victorian specimen, consisting of four disconnected spots only. The pygidium sometimes is entirely black, or varies as in the male. 160 The type of albers: (from North Australia) was described as having the humeral and median spots smaller than the others. This is occasionally the case, but usually the median spot is the largest of all. In the figure it is also shown as isolated. This is also sometimes the case with the typical form, but it is usually joined to the suture. The pygidium was described as brown with the sides testaceous, but in the figures of both sexes the pygidium is shown as being dark in the middle, and on each side of same pale, with outer parts again dark. I cannot regard it as more than a variety of ewenemis. Nigricollis was described as a variety, but evidently from a common form of the female of ewcenemis. No locality for it was given. | Burmeister (29) stated that Schizorrhina obliquata, Westw., was the female of euwenems; but in this he was in error. NEOCLITHRIA EBURNEOGUTTATA, Blanch. encana, Macl. . PI aes stron aii, A damaged female from Dalby has spots somewhat darker than as described, but in the correct positions. This specimen agrees well with Macleay’s description of Cetonia incana, ex- cept that it is slightly smaller. POLYSTIGMA OCTOPUNCTATA, Burm. ochracea, Westw. Pl. vii., figs. 25 to 28. This species has a small black spot on each side of the prothorax, but on the elytra the markings are somewhat variable. There is, however, always present on each elytron a transverse spot just beyond the middle, and a rounded one close to apex ; adjoining the scutellum there is a narrow streak sometimes appearing to be part of the scutellum itself; close to this there is usually a small oval spot, occasionally con- nected with the black streak, but occasionally absent alto- gether. The shoulders are usually immaculate, but some- times there are two (or one) minute blackish spots on each; on one specimen before me (fig. 26) there are two spots on the right shoulder, and none on the left. On the pygidium there is always a conspicuous black spot. On the abdomen and sterna the black or infuscate parts are also variable. Burmeister recorded the name octopunctata as a manu- script one of Hope’s. Westwood in describing ochracea said, “Whether this be a variety of octopunctata, Hope, M.S., I have not at present means of clearly determining ; it seems, (29) Handbuch der Entomologie, iii., p. 799. ¢ 161 however, to agree in general with Burmeister’s short descrip- . tion, except in the maculation of the prothorax and elytra.”’ Burmeister, however, described the prothorax as having a black spot on each side, so that practically the only difference in the markings of the types of ochracea and octopwnctata was on the shoulders, and as noted above these are very variable. Although Burmeister in the Latin portion of his description mentioned but eight spots, in the German portion he mentioned eleven (including the one on the pygidium). He referred the species to Hupecila and Kraatz transferred it to Polystigma. Ochracea was referred to Schizorrhina and transferred by Thomson to Weorrhina. Apparently it was known by the description and figure only to Kraatz. Froggatt in his “Australian Insects” (p. 161) says “a second species, described under the name of octopunctata, is, I think, only a variety” of punctata. This is an error, the species is abundantly distinct from punctata, apart altogether from the markings. The type of ochracea was a male, as the front tibiz were figured as being armed at the apex only. The female differs in having the legs shorter, front tibie strongly tridentate, the other tibie each with a more pronounced postmedian tooth, and the abdomen wider and evenly convex along middle. PoLysTIGMA PUNCTATA, Don. Pe vixe, fies. 54 to 5/5 pl.-xii.; figs. 151,152,153: This species occurs in abundance in the coastal districts of New South Wales, and extends to the far north of Queens- land. In Victoria it appears to be rare. The size ranges from 10 to 16 mm.; and Queensland specimens are usually smaller than those from New South Wales. Perhaps the most typical form is that shown as fig. 56. On the prothorax there are frequently seven disconnected black spots, but often two of these on each side are connected together, sometimes three on each side are so connected, and on a specimen (fig. 57) in the National Museum, Melbourne they are all connected ; this specimen also has the black markings of the elytra greatly extended. On an occasional specimen there are nine prothoracic spots. On each elytron there are usually five disconnected spots, with an additional transverse one connected with the suture towards the apex; but often two or more of the spots are joined together. The spots on the pygidium vary in number from three to seven. The trisinuation of the base of the prothorax is less pro- nounced than in many other Cetonides, but Kraatz was cer- tainly incorrect in describing the base as “fere rectilinea”’ in ’ his generic diagnosis of Polystigma. G 162 POLYSTIGMA CALOPYGA, Nl. Sp. PIs varies (63 pl. xii. ge 184. 3. Head black; clypeus flavous, with two conspicuous black stripes; prothorax black, the margins (but neither the extreme base nor apex) rather narrowly flavous; scutellum flavous, the base partly black ; elytra flavous, suture and sides, a large spot on each side of scutellum, a submedian fascia (connected with suture and sides), a large subapical angular spot on each (narrowly connected with suture), and the shoulders black; pygidium flavous, base and apex red, and three or five spots black, but red where joined to the basal and apical red.

Scutellum with a few small basal punctures. Elytra with prominent shoulders, posthumeral incurvature strong, base with several narrow striz, one of which on each side is continued past the scutellum, and becomes the sutural stria; with small punctures in feeble rows, apex and sides from about the middle transversely or obliquely strigose. Pygidiwm densely, concentrically strigose. Abdomen gently incurved to middle from base and apex, vaguely depressed along middle. Mesosternal process rather acutely produced and curved in front. Legs long, front tibiz strongly dentate at apex only, hind pair with a transverse ridge slightly nearer apex than base. Length, 13-134 mm. Hab.—Australia (National Museum, Melbourne, from C. French) ; Queensland: Cooktown (Blackburn’s collection). Type, I. 1482, in South Australian Museum. The type bore a label in the late Rev. T. Blackburn’s writing, ‘““Hupecila?” Its mesosternal process, abdomen, and legs, however, are more in agreement with those of Polystigma, from all the described species of which it is very different in its markings. These are all connected together on the elytra, but the suture and shoulders in places appear to be diluted with red. When viewed obliquely from above the pygidium appears to have a conspicuous flavous V, the black median 163 spot is strongly narrowed to its apex, the lateral ones on one specimen are connected together, so as to appear like a very irregular vitta, but on the other they are disconnected externally. TRICHAULAX PHILIPSII, Schreib. This species is variable in size, in clothing, and in colour of prothorax. The smallest specimen now before me measures 19 mm., the largest 37 mm. The prothorax in the typical form is of a dingy-red, with the margins black, but the two colours are usually not sharply limited. Most specimens, however, have the prothorax en- tirely black. The clothing varies from almost white, to a conspicuous rusty-red or ochreous. On small specimens the prothorax, whether red or black, is often rather densely clothed, except in the middle; but the sides are sometimes sparsely clothed, even on large specimens. Mostly, however, the prothorax is glabrous. The clothing to a certain extent appears to be deciduous, or at least specimens that have been in spirits for some time are generally less densely clothed that those that have not been so preserved. The extremely active lives led by specimens also probably causes much of the clothing on the prothorax and other unprotected parts to be quickly abraded. Counting from the suture, the first and second hairy grooves are generally conspicuously separated at the base, but on some specimens (particularly on small and very hairy ones) the two appear to be conjoined at the extreme base. This appearance is due to the hair being continued to the base itself, the grooves themselves not being so continued. The size and density of the punctures are also variable. Seen from behind the elytra appear to be supplied with five shining ridges, wide at the base and gradually narrow- ing posteriorly. In addition a less distinct and shorter ridge is present towards each side, but is frequently partly or en- tirely concealed by the clothing. Of the ridges the three outer ones on each elytron are conjoined to form the pre- apical callus; the seventh ridge is the suture, and posteriorly is usually concealed. At the base the two outer hairy grooves (frequently appearing as but one) on each side, are deflected obliquely downwards, so as almost, or quite, to touch the side near the base. The male differs from the female in having a wide de- pression along the abdomen (the female is regularly convex there) ; the prothorax is less transverse, the elytra are some- what narrower posteriorly, and the front tibie are less con- spicuously dentate, the teeth (except the apical one) being G2 164 very feeble or altogether absent. The clothing also is gene- rally denser on the hind tibiz, than on those of the female. The type was described as having the prothorax ‘“‘piceo marginibus atris’’ and the elytral grooves as filled with fulvous hairs. The exact length was not stated, but the figure, ap- parently life-size, measures 34 mm. The figure also has the prothorax coloured a dingy-red. Carinata. I have not referred to the original description of carinata (noted as a variety in Masters’ Catalogue), but in one of the late Rev. T. Blackburn’s note-books, reference is made to the fact that carinata was “deliberately founded upon the type of philips.” Schreibersu. A specimen, sent to me as schreibersi by Mr. Arrow, agrees very well with the typical form, and agrees well with Thomson’s description. It does not appear to be worthy of even a varietal name. Thomson gave its length as 29-31 mm., and stated that it was larger than philipsi, evidently having a small specimen of the latter before him. In Masters’ Catalogue the name appears under Schizorrhina. Kirbyi. This is the commonest form of the species. It has the derm entirely black, and clothing pale-flavous. Donovam. This variety was named from a small specimen with the prothorax red and hairy. A specimen that agrees very well with Thomson’s description is in the South Austra- lian Museum, labelled as carinata in the late Rev. T. Black- burn’s writing ; it measures 23 mm. A still smaller (19 mm.) specimen is in the National Museum, Melbourne. Macleayi. This form appears to be common in the Cairns district and elsewhere in Northern Queensland. Specimens are usually large, with the clothing conspicuously reddish- ochreous, and usually concealing the outer ridge on each side of the elytra. It is a glorious variety. A female of it from the late Rev. T. Blackburn’s collection was marked as having been named by Kraatz. It was recorded as from Western Australia, but probably in error. So far as I am aware no specimen of the species or any of its varieties have been taken elsewhere than in Queensland, New South Wales, Victoria, or South Australia. As regards the latter State, there is a specimen of eine variety kirby: labelled as from Hahndorf. TRICHAULAX CONCINNA, Janson. LA specimen from Carnot Bay, of this beautiful species, is in the National Museum, Melbourne. It has a wide, shallow depression along the middle of the abdomen, and so is a male. Janson noted certain parts as having a coppery tinge; but all parts of the Carnot Bay specimen have a coppery tinge in cer- tain lights. 165 TRICHAULAX MARGINIPENNIS, Macl. Of this species Macleay says “not very shining’; but specimens in good condition are quite highly polished. Mac- leay also described the elytra as having a broad margin of yellow pubescence, and the under-surface as having greenish- yellow clothing. On specimens in good condition, however, the clothing is quite white. SCHIZORRHINA ATROPUNCTATA, Kirby. Bb, fes:o8, 09, 60; pl. xiai., fig. 188. This species usually has three round spots on each elytron, two postmedian and one subapical; sometimes there is an ad- ditional spot close to the scutellum, and sometimes only the two postmedian ones are present. A specimen in the National Museum, Melbourne (fig. 58) has three spots on the right elytron, and four on the left. Mr. W. D. Dodd has recently taken two specimens at the Coen River, each of which has five spots on each elytron, the extra one being on the shoulder. In the female the middle of the metasternum is produced to in front of the middle coxe, then there is a bisinuate suture with the mesosternal process projecting forwards to between the front coxe; the whole of the produced parts being glabrous. In the male the process is distinctly shorter, and is clothed to the bisinuate suture. var. IMMACULATA, Nn. Var. From Northern Queensland.there are now before me five specimens (and I have seen others) that differ from the typical form in being of a dingy greenish-yellow and with the elytra immaculate. Part of the metasternum is blackish and part of the abdomen reddish. The sexes differ as in the typical form. Hab.—Kuranda (National Museum, Melbourne, and H. H. iD. Griffith from F. P.

The males vary in length from 13 to 18 mm., the females from 17 to 20 mm. On the male there is usually an irregular black M on the prothorax, usually connected with the base at two places. but sometimes at three, and occasionally completely divided down the middle. On each elytron there is an oblique vitta from the shoulder to beyond the middle, strongly narrowed — at its middle, and then dilated till it touches the suture and 166 margin. Beyond this there is a disconnected spot with an angular frontal projection. On the female the prothoracic markings are generally smaller than on the male. On the elytra they are sometimes similar, but the oblique vitta on each elytron is frequently broken up into two spots, of which the postmedian one appears (with its fellow on the other elytron) as a more or less zig-zag fascia, but sometimes the apical portion appears as a small disconnected spot of irregular shape. The markings on the pygidium also vary considerably in size. LYRAPHORA BASSII, White. [ee oMentier, Ne) coll, oti. ie elo All the specimens that I have seen of this species have two black spots on the prothorax and three on each elytron ; as on the type. The spots are always in the same positions and vary but slightly in size. LyRAPHORA VELUTINA, Macl. Pl. ix., figs. 65 to 68. On this species there is a more or less M-shaped blotch on the prothorax, that is but seldom broken up into spots. On each elytron there are usually four spots: one on shoulder, one touching the hind margin of the scutellum, one (usually transverse) just beyond the middle, and the fourth close to apex. The third spot is sometimes joined to the suture, but is usually free. On a specimen in the National Museum, Melbourne (fig. 65), it is joined to the second spot. One small male (fig. 68) is without the humeral spot. Three of the specimens before me have the derm shining ; but this was probably caused by improper treatment. LYRAPHORA VITTIVARIA, 0. sp. LE Wits Ae YS olla Scom mens 710), o. Flavous; head (except for a subtriangular space in front of the clypeus), a large irregular somewhat M-shaped blotch on prothorax (connected in two places with the base), margins of scutellum, suture, sides, and some markings on elytra, base, apex, and some spots on pygidium and under- surface (except some spots at the sides and the mesosternal process) black. Head with rather small, irregularly-distributed punc- tures. Clypeus ridged towards each side, but the sides them- selves rounded, apex moderately notched; punctures more distinct than on head; club about as long as the space bhe- tween eyes.

Hab.—Queensland: Coen River (H. Hacker). Toe in National Museum, Melbourne, from C. French. It is with some hesitation that I describe the two speci- mens before me as representing a new species, rather than a variety of the very variable obliquata. They differ, how- ever, from males of that species in having the upper-surface opaque instead of shining (but one specimen has parts of the upper-surface shining), the abdcmen entirely black except for some marginal spots, and the legs paler. The pale portions of each elytron also are all connected together, instead of being isolated from each other into two or three parts. On the type the prothoracic blotch has a triangular notch at its apex, on the other the notch is continued almost to a trans- verse subbasal pale space. On each elytron of the type there is a somewhat dumb-bell-shaped oblique vitta from the shoulder to beyond the middle, almost connected with the side but distinctly separated from the suture; near the apex there is a large spot, rounded behind and with a pointed projection in front; adjoining the scutellum there is a large spot, and there is a narrow black mark on the hind portion of the suture. On the second specimen the discal markings on each elytron are connected together, and a'so connected with each other by way of the postmedian sutural mark which is larger than on the type. On the type there are four dis- connected spots on the pygidium, on the other there are but two. The upper-surface is covered with an opaque indumen- tum, which partially or entirely conceals the punctures. On the elytra there appear to be feeble rows of shallow punctures, but where the indumentum has been rubbed away these be- come much more distinct. ABLACOPUS TRAPEZIFER, Thoms. Pin, wo, (1. plexi ees. 126 to 13) > plex. fives. 154, 155, 156, 165, 166, 167. This species is fairly common in Northern Queensland, and varies in length from 17 to 25 mm. The prothoracic 168 blotch varies from entire and more or less subtriangular im shape, to somewhat M- (or reversed W-) shaped, with the parts sometimes disconnected. The scutellum varies from pale with very narrow black margins to entirely black. The abdomen is sometimes of a very dark red without side spots, but is usually black, with conspicuous flavous spots at the sides. The pygidium is immaculate, or with a conspicuous: somewhat elongated black spot on each side (on some speci- mens the spot on each side is not black, but has a vague watery appearance, although of the usual shape, size, and position). On two females the lateral spots are absent, but there is a minute black spot on each side of a faint medio- basal extension. The femora and tibiz are usually pale with dark tips; but the tibiz are sometimes entirely dark. A female in the National Museum, Melbourne, has the elytra. (except for the sutural marking) entirely of a deep chestnut-red. Another female (fig. 71) in that Museum has the prothoracic blotch connected along the middle with the base, each shoulder and the subapical callesities black; the sterna (except for a minute spot on each side of the mesosternum), abdomen, and pygidium black (the latter with the conspicuous subapical carina of the females of the species), and the legs black except for a narrow border in front of the hind femora, and the lateral margins of the hind coxz. The clypeus has a pale spot on each side, with a minute black spot in the middle of each. A male, in the same Museum, has a vague dark cloud on the suture from just beyond the middle to near the apex. Another male, in the same Museum, was labelled Chondropyga notabilis and as from Western Australia. But the locality and identification are almost certainly incorrect. It differs in many respects from the description of notabilis- On its prothorax there is a well-defined M (fig. 128). ABLACOPUS, Sp. PS xa ee tio. Lode There are three specimens before me that I hesitate to associate with either teniatus or trapezifer, although they pro- bably belong to the latter species. ‘They all have the inter- coxal process of the mesosternum decidedly wider than is usual in those species. Fig. 131 will give a general idea of the prothoracic blotch, which is very similar on all three. A male (17 mm.) from Cairns, from Mr. Cox’s collection, has the front tibiz tridentate, as on the female of trapezifer,. the middle femora moderately fringed behind and feebly in front, the legs dark-red, with tibie darker than femora, and the tarsi black. Its pygidium has the usual two black spots. A female (19 mm.) in the National Museum, Melbourne, 169 has the clypeus entirely dark; the pygidium (fig. 157) widely black at base and apex, leaving a transverse pale portion with- out spots, and its apex is non-carinate. The under-surface and legs are dark-red and immaculate. A female (21 mm.) from Stannery Hills, New South Wales, ‘5° in Mr. French’s collection has the head, prothorax, pygidium, under-surface, and legs much as in the preceding specimen, but the scutellum is not entirely black, and the elytra are paler on the apical third than on the basal two- thirds. ABLACOPUS THNIATUS, Schoch. Bix ties: (2 to ./5;, pl. xiii, figs. 163, 164. The typical form of this species is sufficiently distinct from the typical form of trapezifer. But both species vary considerably in size and markings, and it is not always easy to separate them. But as a rule the males may be distin- guished by the middle femora, and the females by the pygidium. On the male of trapezfer the middle femora each have two fringes of long hairs on the under-surface, the space between the fringes being quite glabrous, sometimes but one fringe is distinct, the second being represented by a few short setz only, but the space between is always glabrous. On tanmiatus, on the contrary, the interspace is very densely clothed, so that the whole of the under-surface of the femur appears like an elongated pad. On the female of trapezfer the lower portion of the pygidium has a distinct median carina, of which there is no trace on the female of teniatus. The specimen doubtfully figured by Janson (Cist. Ent., 1.) as Diaphomia notabilis almost certainly belongs to teniata. I have seen three females agreeing perfectly with the figure. ‘One of these has the two apical segments of abdomen partly yellow (although not yellow margined with black), but the others have those segments entirely black. The prothorax on the type of teniatus (but not of notabi- lis) had a stripe on each side pale, with the black blotch con- nected with base and apex. Three such specimens (all males) are before me, on another male there are three small pale spots along the middle (fig. 73), but the blotch is connected also with both base and apex. On all the females () the blotch is disconnected with the margins and has a pale stripe or elongated spot down the middle (as figured by Janson). (30) It is the only specimen of the genus that I have seen from that State. (31) Except the specimen from the late Mr. Elgner. 170 The scutellum varies from pale, with very narrow black margins, to entirely black. The elytra vary from a form with the suture narrowly black, and shoulders not spotted, to forms with a fairly wide sutural stripe, and a distinct spot on each shoulder. One male, in the National Museum, Melbourne, has the humeral spot black, with the sides thence to the apex irregularly mottled with brown, of a sufficiently dark shade to cause the space between it, and the sutural patch to appear conspicuously striped (fig. 74). The pygidium in the female is pale, with very narrow black margins, and sometimes with a medio-basal spot con- nected with the base. On the male there is a distinct black spot on each side, and the medio-basal spot is more distinct than is usual in the female. The sterna and abdomen are black with pale spots on the sides. The hind femora are usually black with the front margin pale; but on one male they are entirely pale (although darker on the lower than on the upper parts). On this specimen also the four front femora and four hind tibiz are obscurely diluted with red in places. The clypeus varies from almost entirely pale, to about three- fourths black. The front tibize of the female are tridentate, but on one specimen the subapical tooth is very feeble, and on others they are apparently identical with the front tibie of the male. The size varies from 17 to 19 mm. A female from Northern Queensland (from Mr. Elgner). seems greatly aberrant, as the only parts that are pale are an irregular patch on each side of the clypeus, a narrow flavous border on each side of the prothorax, the pygidium (except at base and apex), some spots at the sides from mesosternum to apex of abdomen, a spot on the mesosternal process, and an irregular mottling of the hind femora. But as I cannot distinguish it structurally from other females, presumably it is a variety of the species, despite its entirely black elytra and scutellum. ABLACOPUS ATER, Schoch. Pl. xii., figs. 117, 118, 119. This species was made the type of a new genus (Anthra- copharis) by Schoch, who stated that it would not fit into any previously known one. It is, however, absolutely con- generic with Albacopus trapezifer, originally referred by Thomson to Diaphonia, but subsequently made the type of his new genus Ablacopus. In fact, I am unable to define a single structural feature by which a specimen, sex for sex, may be distinguished from trapezifer. There are now before me seven males and two females (the latter sex was unknown to Schoch), ranging in length from 20 to 25 mm. Of these three males agree with the type 171 in being entirely black; one is black except for a spot on the clypeus; another is black except-for a similar spot, and some vague spaces on the elytra near the suture about base and apex ; another has a spot on the head, a fairly large irregular space on each side of the prothorax, and a vague oblique space on each elytron from the shoulder to near apex obscurely diluted with red; the seventh has a fairly large spot on the head (the spot itself with a black circular spot on each side), a minute spot on each side of the prothorax, and much of the elytra pale; the pale portion on each elytron is almost flavous, but clouded in places, it extends from near the base to near the apex, starting at a short distance from the suture, and extending to about one-third from the margins, but with an infuscate line for about ‘two-thirds of its length down the middle. Of the females one has an almost equal amount of the elytra pale to that of the seventh male, but the infuscate line is wanting, and there is an infuscate cloud extending into the pale portion from the posterior half of the suture. On this specimen there is a scarcely traceable spot on each side of the prothorax, and the clypeus has a fairly large pale space, with a distinct black spot on each side, and a vague median line. The other female has a fairly large pale spot on the clypeus, with a distinct black spot in the middle, and an obscure one on each side, its prothorax at first appears to be immaculate, but on close examination a vague spot may be seen on each side. Each elytron has a fairly large space diluted with red along the middle, the markings distinct, but not sharply defined. Structurally the female differs from the male in being rather stouter, tarsi shorter, front tibize tridentate 2) and each of the middle ones as well as the hind ones with a median tooth, its abdomen is strongly convex along the middle, and its pygidium is acutely carinated posteriorly.)

The male has a wide shallow depression along the middle of the abdomen, and is generally somewhat smaller than the female, with the large black blotch of the upper-surface more sharply defined. I cannot regard breweri (whose larve also occurs in rot- ting cores of species of Xanthorrhea) as more than a variety. Specimens from Western Australia (one of which was iden- tified by Mr. Arrow as breweri) have the punctures of the clypeus, prothorax, and elytra much as on some Sydney specimens. But Western Australian specimens sometimes have the prothorax and elytra almost entirely reddish- castaneous, the only distinctly dark part of the upper-surface being the scutellum. var. MELANCHOLICA, nN. Var. A female (in the National Museum, Melbourne) labelled as from Queensland and F. H. duBoulay, apparently belongs - to this species, but is entirely black, except for a minute red- dish spot near the top of the pygidium, and two where the hind coxe almost touch. In all structural details it agrees abso- lutely with normal females. CACOCHROA GYMNOPLEURA, Fisch. A specimen (from New South Wales) in Mr. French’s collection may be an immature female of this species; it differs from the typical form in having the head in front of the eyes red, the prothorax black with the sides and base of an obscure deep-red; the elytra of a dingy flavous with the suture and shoulders black, narrowly bordered with dingy-red; the pygidium entirely and the abdomen partly red; and the legs more or less obscurely reddish. In all structural details it agrees with normal females. A male labelled as from Roebourne, 4 also in Mr. French’s collection, appears to be an unusually small (13$ mm.) form of the variety concolor, with the head and pro- thorax much hairier than is usual. CACOCHROA DECORTICATA, Macl. var. assimilis, Macl. var. neva, Gestro. Pl. x., figs. 76, 77, 78. The female of this species is much rarer than the male, and has no white clothing on the sides of the prothorax. The (34) North-western Australia; probably an incorrect locality. 173 spot on the disc of each elytron is greatly reduced in size (compared with that of the male) or altogether absent, and the white spots on the pygidium are also reduced in size. Such specimens in colour agree well with obscura, but have much more defined punctures. On the male the white cloth- ing on the sides of the prothorax is usually continuous, but is sometimes partly or completely divided in the middle. The elytral spots also vary in size and shape. The species was referred by Kraatz to Lyraphora, but was made the type of a new genus (Camilla) by Thomson. I cannot regard Schizorrhina neva as more than a slight variety of the species. CACOCHROA VARIABILIS, Macl. Pi x, fess 79 iho / 84. There are before me numerous specimens that appear to belong to this species; but they vary considerably in size (14-19 mm.) and colour ; and to a certain extent in the elytral punctures; these being much finer on some specimens than on others. Three colour varieties were described by Macleay. But the sculpture and size were apparently alike on all three; or at least there is no indication in the description to the con- trary. Of the supposititious non-variable details in the original description the following may be mentioned: ‘“Femoribus tibiisque posticis subtus villosus,’’ and again, “the inferior margin of the hind thighs and tibie are clothed with a uniform thick brush of cinereous hair.’”’ Of the elytra, “lineis duabus longitudinalibus suturaque subelevatis glabris.’’ The size of the elytral punctures is nowhere mentioned, but on the head and prothorax they were mentioned as finer than on gymnopleura. Macleay did not describe one form as typical and the others as varieties, but described the species as being com- posed of three varieties. It would perhaps have been better had he described one form as typical, and the others as varieties, but as he numbered them respectively 1, 2, and 3, it appears desirable with additional varieties to continue his arithmetic. Var. 1.—A rather small (14 mm.) male from Rockhamp- ton evidently belongs to this variety. Its hind legs are as described, and its elytral punctures are fairly coarse and in somewhat irregular rows, extending neither to base nor apex. Two females, from Cairns, of the variety, differ in being larger, with much finer and scarcely-seriate elytral punctures, and only the hind tibiz densely fringed, although about the base of each of the four front femora there is a fairly conspicuous ’ fringe. 174 Var. 2.—A specimen (fig. 79) labelled as variabilis by the late Rev. T. Blackburn, evidently belongs to this variety. It is of a deep-red, with the base of the head, two large pro- thoracic spots, the scutellum, and a sutural vitta black; the vitta is wide at the base and is regularly narrowed till it disappears at the apex. It is a male and has the femora and hind tibiz fringed as noted under var. 3. Three specimens, two of which are from Cairns, are females of this variety, and one (fig. 80) is labelled variabilis by the late Rev. R. L. King, but without locality other than Queensland. They are of a still deeper red than the male, one being so dark that the black prothoracic spots (which on it are of greater size than usual) are very ill-defined. The scutellum is obscurely diluted with red, and the suture is very narrowly black. Two have the pygidium mostly red, but on the other it is black. The elytra are without elevated lines of any kind, except the hind portion of the suture, but they are feebly undulated in places ; their punctures are also noticeably smaller than on the male, being, in fact, very small. The femora are feebly fringed, but the hind tibiz are almost as densely fringed as in the male. Two other females have the hind tibie feebly fringed, but otherwise they agree with the two having the pygidium red. Var. 3.—Two other specimens evidently belong to Tee variety. One (fig. 81) bears a label by the late Rev. R. L. King, ““Hupecila variabilis, McL., Port Deniston’’ ©); the other was labelled, “2076, variabtlis, Macl.,’’ by the late ‘Rev. T. Blackburn. They are males and have the hind tibie and femora densely fringed on the lower-surface; their four front femora are also fringed, but less conspicuously so. The front tibiz have a strong apical tooth and a feeble subapical one. Their legs are mostly red, the tarsi and hind tibie being black or blackish. The amount of dingy-red at the sides of the prothorax and elytra varies. One has the pygidium black, and the other only partly so. The suture is distinctly elevated posteriorly, but the other longitudinal elevations are very feeble. I have seen no females of this variety. Var. 4.—A female (fig. 82) from Northern Queensland, in the National Museum, Melbourne,evidently represents another variety. It is black with the apical half of head, sides and apex of prothorax, elytra (except for a wide sutural vitta), and most of pygidium and of legs of a deep-red. Only its hind tibie are densely fringed. A specimen, from Kuranda, in Mr. Griffith’s collection, is very similar in general appearance, but has the elytra entirely of a deep-red, and the pygidium black but obscurely diluted with red in the middle. (35) Port Denison was the type locality. 175 Var. 5.—Another variety (figs. 83, 84) is common in the Cairns district. It is of a rather pale-castaneous, with each side of base of head, two prothoracic spots of variable size, scutellum (wholly or in part), sterna (except the sides and the mesosternal process), and abdomen black. On each side of the prothorax also there is sometimes a small infuscate spot. The male has the hind femora and tibiz densely fringed on the lower-surface, and ‘the other femora moderately fringed. The female has the femoral fringes much less conspicuous, and the fringe on the hind tibie very feeble. Both sexes have the punctures of the upper-surface rather more con- spicuous than usual, although much smaller than on gymno- pleura. One of the females, in Mr. French’s collection, is labelled as from York (in Western Australia), but this is certainly an error, probably Cape York in Queensland was meant. Disregarding colour the females of the species differ from the males in being larger, elytra distinctly wider, less nar- rowed posteriorly and with decidedly finer punctures; abdo- men evenly convex instead of depressed along middle and hind legs with their femora much less conspicuously fringed than their tibie, or sometimes with both femora and tibize feebly fringed. The differences in the dentition of the front tibiz are slight and apparently somewhat variable. CACOCHROA PULLATA, Janson. There are five specimens from the Endeavour River, under examination, that agree with the description of this
