GENERA OF AFRICAN LYCAENIDAE 



149 



II nig shape. (J fore wing inner margin lobed ; hind wing hind margin angled at vein 3, a 

 delicate tail at vein 2, another much longer at vein ib, anal angle lobed. Male secondary 

 sexual characters : a hair tuft on the inner margin of the fore wing below, an androconial patch 

 surrounded by a wide glossv area, at the base of the hind wing above. 



W ing venation. Fore wing with 11 veins in both sexes. 



Male genitalia (Text-fig. 133). Very different from all the other Iolaus, justifying separation 

 as a distinct subgenus. Uncus composed of two small lobes roughly subtriangular in shape 

 and distally strongly serrate ; tegumen very big, but with its distal margin deeply indented, 

 centrally reduced to a narrow band ; vinculum broad, with a short round saccus ; lower 

 fultura carried on a short stalk ; valves small in relation to the dorsal structures, deeply incised 

 the two processes separate almost to the base, upper process with serrate apical edge ; the 

 distal part of the lower process cut to form sharp teeth of which the longest is bent back like a 

 sickle ; penis small, almost straight, the outer part tapering evenly ; uncus and upper process 

 of valves lightly pilose.

This species is very seldom represented in collections. It was described on the 

 basis of the unique male now in the British Museum (Natural History) the provenance 

 of which could be Gaboon or even the East Indies 1 . I am indebted to the late 



1 While the present work was already in page proof, I was informed by Ft. Col. C. F. Cowan that 

 /. (S.) mores had recently been collected in N. E. Borneo, thus confirming that its distribution is Indo- 

 Malayan, not African.
