S$. FLETCHER t ot the British Museum 7, Noctuidae By D. S. FLETCHER British Museum (Natural History) The Noctuidae collected during the British Museum expedition to East Africa in 1934-5 and during the expedition to Ruwenzori in 1952 together consist of 1139 specimens representing 252 species, of which 104 proved to be new to science. Two species, Saltia edwardsi Tams and Sesamia oriqula Tams & Bowden, have already been described elsewhere; 76 species and two subspecies are described in the following pages and 26 species have been referred to genera only, to await further material. Of the 252 species collected, 161 are from Ruwenzori and 91 from various localities in Kenya and Uganda visited by the two expeditions. Certain additional material from the unnamed accessions in the British Museum and specimens collected by A. Holm during the Swedish expedition to the mountains of East Africa in 1948 and kindly loaned by Dr. René Malaise of the Riksmuseum in Stockholm have also been included in this paper. The majority of the species of Noctuidae collected from the lower elevations of Ruwenzori, from the savannah and the partially cultivated elephant grass belts and from the lower levels of the montane rain forest belt, between 6000 and 8000 ft., have a wide distribution in Africa and no doubt the species from these belts, described as new in this paper, will eventually be shown to have a similar distribution. Above 8000 ft., from the upper levels of the montane rain forest belt to the limits of vegetation n the alpine belt, most species of Noctuidae have a more restricted distribution. Of the twelve jpreviously described species recorded from the upper levels of the montane rain forest belt and ibove, only four are known to have a wide distribution in Africa. Of the thirteen species now mown from the ericaceous and alpine belts, only Elaeodes barnsi A. E. Prout, described from \Sivu material, is known in the typical form from a locality other than Ruwenzori. The species known to occur at 8000 ft. and over on Ruwenzori are listed below, arranged in he vegetation zones with which they are associated. The known distribution of previously _jlescribed species is given in brackets. In the absence of a more modern and complete classification of the Noctuidae, that used by Jampson in Cat. Lep. Phalaenae B.M. has been followed, with minor modifications. | Below each previously described species is given its known distribution at the time this paper H vas prepared. All specimens, unless otherwise indicated, are in the British Museum. | The colour names used in the descriptions of new species are taken from Ridgway’s Color \tandards and Color Nomenclature. us i7y7 Ruwenzori Expedition, 1952.

Hind wing as in the preceding species. Genitalia of both sexes as illustrated. The eighth sternum of the male bears a dense tuft of hair-scales. These scales are deciduous and may fae been lost from examples of the other species, either before or pune preparation of the genitalia. Related to E. callima, differing in its smaller size and in pattern. Differs structurally in the male genitalia, in the shape of the valve and its shorter processes and in the additional cornutus on the vesica. In the female genitalia the sclerotization of the ductus bursae and the bursa copulatrix is reduced and both parts differ in shape from those of callima.

RUWENZORI: Nyinabitaba, 8650 ft. (Fletcher), 1 3. Distribution: Nyasaland. Rather larger (34 mm.) than the type (29 mm.) and with slightly modified genitalia; adequate material may show the Ruwenzori population to represent a distinct subspecies. Two specimens from Mt. Kenya, with genitalia closely similar to those of the holotype (Figures 172, 173), measure 38-40 mm. in wing-span. Dicerogastra gen.n. Frons smoothly rounded. Wing pattern of fore wing similar to that of an Orthosia, especially in the smooth, sharply defined subterminal fascia. The structure of the genitalia indicates an affinity to Xylomyges, from which it differs in the male in the short, rounded saccus, the well developed cucullus and the dense cluster of spines on the valve; differs in the female in the more strongly developed ovipositor, the less specialized eighth sternum and the absence of signa on the bursa copulatrix. Male genitalia. Uncus simple, tapered and densely scaled dorsally.

Examination of the holotype of Xylomania nigricincta Gaede (1916), kindly loaned by Dr. H. J. Hannemann of the Zoological Museum in Berlin, has shown it to be a synonym of geraea Hampson (Syn.n.). Agrotis mesomelaena Hampson (1902) and Craterestra semifusca Hampson (1905) have genitalia closely similar to those of Omphalestra, but cach species lacks the tufts on the first abdominal segment, so they are only provisionally referred to this genus: semifusca differs further in having a slightly protuberant frons and may eventually require a separate genus.

Distribution: Sudan; Uganda; Kenya; Nyasaland. Apospasta dipterigidia fulvida subsp.n. (Figures 179, 181) Differs from A. d. dipterigidia (Hampson, 1902) externally in the less contrasted colouring of the fore wing; the cinnamon ground colour is more evenly suffused with vinaceous brown and the fuscous irroration is confined to the veins. In the male genitalia, the anterior of the two processes on the basal third of the valve is evenly digitate; in the nominate subspecies it is comma-shaped with a very slender base; the posterior process is triangular with a very broad base; in the nominate subspecies this process is evenly digitate. The vesica bears a straight, stout, tapered cornutus, one-half as long as the aedeagus; in the nominate subspecies (Figure 180) the cornutus is two-thirds as long as the aedeagus and is curved through 90° at base. In the female genitalia the operculum is broadly bilobate posteriorly and is incised to less than _ one-half medially; in the nominate subspecies (Figure 178) the lobes are long and slender and the - medial incision extends to three-fourths. The following notes on the larva have been recorded by Mr. A. L. H. Townsend of Nakuru, Kenya Colony: ‘First bred in 1937.

In the structure of the male genitalia, jacksoni is more closely similar to fuscirufa than to venata. The costal process on the dorsal margin of the valve, just anterior of the cucullus, is disc-like and projects dorsad in fuscirufa; in venata this costal process is wanting.

The underside differs in the weak development of the cell spot on the fore wing (wanting in kennedyi) and in the larger cell spot on the hind wing, extending along nearly the whole length of the discocellulars. In the male genitalia the posterior of the two processes on the basal part of the valve is more slender than the corresponding one in kennedyi and the anterior one is smaller and sharply tapered apicad; the cucullus is also smaller. In the vesica, the medial scobinate area of kennedyi is wanting; a much more finely scobinate area is situate apicad; the basal cluster of spines is shorter than in kennedyi.

Uncus simple and tapered, densely scaled dorsally. Valves free, shaped as illustrated, with two short, digitate processes arising near base of dorsal margin. Aedeagus short, stout and sinuous; vesica minutely and densely scobinate, bearing one or two clusters of short, stout spines. First abdominal segment with a pair of long, dense hair-tufts. Female genitalia. Ductus bursae with two sclerotized folds, one at each side; ductus seminalis dilate, forming an additional sack, closely wrinkled and sometimes sclerotized at junction with bursa copulatrix, which bears four longitudinal signa and is sometimes partially sclerotized. The gender of the generic name is masculine. Types species: Apamea inferior Guenée (1852) (Figures 94, 98, 175).

Re-examination of the types of Dianthaecia praetermissa Walker (1857) and its synonym Hadena depulsa Walker (1857), included by Hampson in the synonymy of Miselia renisigna Walker (=inferior Guenée), has shown them to represent a distinct species, distinguishable externally by the clear white or buff reniform and orbicular spots on the fore wing, the latter spot usually extending to the costa, and by the paler proximal part of the hind wing. In the male genitalia, the vesica of inferior bears a single cluster of spines; in praetermissa there are two such clusters. In the female genitalia, the bursa copulatrix of inferior is sclerotized posteriorly; in _ praetermissa it is membranous. Tycomarptes tortirena (A. E. Prout) _ Graphania tortirena A. E.

In describing P. ragusanoides, Berio (1954, Mem. Inst. Sci. Madagascar, (E) 5:134) has shown that the Madagascan representative of ragusana differs structurally from the nominate form. The genitalia of the type of Hypena quinquelinealis Moore (1877), hitherto regarded as a synonym of ragusana, show similar differences from both ragusana and ragusanoides. Specimens from Kenya and Uganda also differ from the three taxa already mentioned, but a revision of the species group should be undertaken before further names are added to the literature.

Antennae in both sexes minutely ciliate. Palpi equal in length to twice — diameter of eye, second and third segments long and of equal length. Abdomen drab grey; _ remainder of vestiture and fore wing white irrorate, densely in holotype and allotype, with mouse grey and black. Fore wing: a black basal streak in subcostal fold; basal fascia black, toothed sharply distad on subcostal fold; antemedial fascia black and dentate, toothed sharply distad on discal | and submedial folds and proximad on radius, cubitus and anal vein; postmedial fascia black, — bulged distad in discal area with a slender beak-like projection proximad along discal fold; terminal interneural dots black; some tawny scaling on discocellulars; cilia black proximally, mouse grey distally. Hind wing tilleul buff suffused with drab; termen slenderly light buff; cilia drab proximally, white distally. Fore wing in female paratype less densely suffused and pattern, as a consequence, more clearly defined. ie Male genitalia. Uncus short and simple. Saccus produced and broadly rounded. Valve bifid, ventral arm membranous, dorsal arm slender and arcuate with apical third densely covered with hair scales. Aedeagus slender and straight. Vesica without cornuti.

Noctuidae 225 Slightly larger (wing-span 22 mm.) than P. atripuncta Hampson (1912) and differing from it in colour and pattern, but apparently identical in structure of genitalia. The genitalia of P. melano- sticta Hampson (1912) are also closely similar to those of atripuncta. As only four specimens alto- gether are known, it is not possible to reach any firm conclusion. P. punctata Hampson (1902) may prove to be the female of atripuncta. Pardasena virgulana (Mabille) Sarrothripa virgulana Mabille, 1880, C.R. Soc. ent. Belg., 23: xvii.
