\ REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 47 



medially directed reddish brown fringe ; rest of leg pale buff. Colour of remaining legs doubtful, 

 but probably similar to fore leg. 



Venation as for species-group erosa. Ground-colour of upper surface of fore wing yellowish 

 brown ; speckled with highly lustrous scales, most densely at base at costal area ; very pale 

 brown medial area bordered proximally with dark reddish brown, and with reddish brown streak 

 extending from it distally between anterior angle of cell and apex ; small brown discocellular 

 spot ; postmedial fascia narrow, pale. Upper surface of hind wing yellowish brown (much paler 

 anteriorly in area overlapped by lore wing) lightly speckled with highly lustrous scales post- 

 eriorly ; discocellular spot small, brown ; pale postmedial fascia strongly concave ; weakly 

 marked brown subterminal spot between .1/., and C;* ia . (Plate 17, fig. 342.) 



Under surface of both fore and hind wings pale buff, lightly speckled with dull pink scales (most 

 conspicuous along veins) ; speckled with dark grey at apex, outer margin and proximal half of 

 costal area in fore wing, and over whole of hind wing except along anal margin. Both wings 

 with conspicuous dark grey discocellular spot and postmedial fascia. 



Colour of abdomen doubtful. 



o* genitalia (Text-figs. 71-73) '. vinculum strongly developed, the two sides closely apposed 

 along mid-dorsal line, produced posteriorly on either side into heavily sclerotized, trifurcate, 

 i law-like structure ; diaphragma almost completely sclerotized, membraneous only along medial 

 line where it is weakly sulcate ; uncus absent ; aedeagus sharply recurved apicallv, vesii a 

 without ornamentation ; posterior margin oi eighth sternite strongly concave ; apodemes 

 moderately long. 



?. Not known. 



Mkasurements. A.P.k. : <£. 9. Wing : q*. 24-0 mm. (1). 



Discussion. Without knowledge of the female it is difficult to assess the 

 taxonomic position of this species. The venation of the fore wing is similar to that 

 of the species-groups erosa and seydeli but the male genitalia are so different from 

 those of erosa or seydeli that it is impossible to place efalena in either of them. It is 

 difficult to see how the curious, paired, clawed structures of the male genitalia of this 

 species could have been derived from the uncus or valves of any known species of 

 Epicampoptera. 



Distribution. Known only from the type locality. 



Material examined. Type. Holotype <J, Cameroun, Efulen, 13.xi.1912 

 (Weber) ; Drepanidae genitalia slide No. 1529 ; in the Carnegie Museum, Pittsburgh.
