A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 77 



upper surface of both wings, slightly yellowish brown with greyish brown markings. Under 

 surface of both wings dull pinkish grey, speckled and striate with darker grey ; oblique, dark 

 grey, postmedial fascia on fore wing and trace at anterior margin of hind wing, bent away from 

 apex just before costa on fore wing. 



Coloration of abdomen doubtful. 



$ genitalia as in Text-figs. 118-120. 



?. Not known. 



Measurements. A.P.R. : <J. 9. Wing : <$. 18-7, 18-5-19-0 mm. (2). 



Discussion. The phylogenetic position of this species is doubtful, although the 

 shape of the aedeagus and eighth abdominal sternum suggest affinities with subtilis 

 Bryk. The colour-pattern readily distinguishes it from subtilis, and from gonioptera 

 which is similar to albiapex in coloration. 



Distribution (Map 4). Only two specimens are known : one from the Congo 

 and one from Uganda. A male from the Usambara Mountains, Tanganyika (in 

 the collection of the National Museum of Southern Rhodesia), which differs in minor 

 respects in the male genitalia, will probably prove to represent a new subspecies 

 of albiapex when further material becomes available for comparison. 



Material examined. Type. Holotype <$, Uganda, Ankole, Kalinzu Forest, 

 xi.1961 (Carcasson) ; Drepanidae genitalia slide No. 1365 ; in the British Museum 

 (Natural History).

Lomadontophana gonioptera (Hampson) ; Gaede, 1931 : 51. 



Diagnosis. <$. Wing shape and colour pattern as in Plate 7, fig. 298. Ground-colour of 

 upper surface of wings dull yellowish brown ; under surface dull greyish scarlet distally, reddish 

 buff at base, fore wings more greyish distally than hind wings. Legs scarlet on front surface, 

 buff on rear surface, fore legs most intensely coloured. Aedeagus arcuate apically ; eighth 

 abdominal sternum with characteristic antler-like posterior processes (Text-figs. 1 21-123). 



Similar in coloration to albiapex but with distinctive genitalia. 



$. Not known. 



Measurements. A.P.R. : <J. 9. Wing : £. 19-5 mm. (2). 



Discussion. The affinities of this species are uncertain until female material 

 can be examined. 



Distribution (Map 4). Known only from Nigeria and Cameroun. 



Material examined. Type. Holotype J (not $ as stated by Hampson), 

 S. Nigeria, Ilesha (Humfrey) ; Drepanidae genitalia slide No. 621 ; in the British 

 Museum (Natural History).
