GENERA OF AFRICAN LYCAENIDAE 



255 



Eyes glabrous, palpi long, ascending, second segment laterally compressed, clothed below 

 with white scales and long black stiff hair, third segment long, slender ; antennae slender, 

 half the length of the costa, club oval, well differentiated ; (J fore leg, tibia with a spur and 

 almost as long as femur, tarsus unsegmented, finely spinose below. 



Wing shape. Fore wing subtriangular, costa evenly convex, apex rounded, outer margin 

 convex, hind wing oval, no tail. 



Wing venation (Text-fig. 343). Bethune Baker (1914 : 330) described the venation of the 

 fore wing of barberae in these words, " Veins 6 and 7 arise from the upper apex of the cell and 

 7 is not stalked, 8 and 9 are absent, 1 1 is bent up to almost or quite touch 12 ". The venation 

 of barberae is probably not stable and Bethune Baker must have examined an aberrant specimen. 

 In the five specimens that I have examined the venation is as follows : — Lore wing with 10 

 veins ; the cell short ; 3 from before the lower angle of the cell ; 4 from this angle ; 5 equi- 

 distant from 6 and 4 ; 6 from the upper angle of the cell ; 7 from rather far before this angle, 

 ending in the apex ; 8 and 9 absent ; 10 from the upper edge of the cell ; 1 1 reduced to a short 

 cross-vein between 10 and 12. 



Male genitalia (Text-fig. 220, side view ; parts in situ Text-fig. 221) posteri-ventral view 

 of the dorsal structures under higher magnification with the parts spread out and flattened 

 (see also Bethune Baker, 1914, fig. 41). In general plant the structure is similar to that of the 

 o* genitalia of B. exilis. Directly fused to the vinculum there is a broad grooved blade stretching 

 horizontally to the rear ; above and parallel to this blade there is a process resembling a long- 

 handled fork with two sharp-pointed prongs ; lobes of tegumen very large, convex, each with a 

 deep depression in its posterior edge, and a long digitate process on its inner surface which, 

 instead of surrounding the external edge as in Brephidiutn, is directed to the rear so that its 

 apex protrudes considerably beyond the posterior edge of the tegumen ; vinculum narrow, 

 lower fultura formed of two long slender arms which are fused to the valves, not at their base 

 but at one-third from the base ; valves small, oval, their lower margins fused throughout the 

 first third from origin ; penis very specialized, internal portion massive, saddle-shaped, external 

 portion divided into two slender processes which diverge slightly apical ly where both the upper 

 and lower edges are slightly serrate ; posterior margin of tegumen clothed in long hair, especially 

 in the middle, the digitate processes are also clothed with hair along the whole of their length 

 and bear a pencil of long stiff hair at their apices, the lobes only sparsely clothed with short 

 hair, distal portion of valves clothed with finer and shorter hair than that on the posterior 

 edge and processes of the tegumen.
