GENERA OF AFRICAN LYCAENIDAE 173 



from 3 to the inner angle ; hind wing subtriangular, costa convex at the base, outer margin 

 scalloped at the ends of vein 5 to 3, a short, rounded tail at the end of vein 2 and another slightly 

 longer at the end of vein lb, a small, weak lobe at the anal angle. 



Wing venation (Text-fig, 309). lore wing with 12 veins. 



Male genitalia (Text-fig. 154). Incus subrectangular, the distal margin rounded at the sides 

 and with a slight median, obtuse protuberance ; subunci long and robust, strongly curved, 

 tapering evenly to the apices ; tegumen oval, its proximal edge jutting out towards segment 8 ; 

 in situ uncus and tegumen together are hood-shaped ; vinculum narrow, with a robust tri- 

 angular saccus ; lower fultura crescentic ; valves oblong, subtriangular, with rounded, serrated 

 apices, the edges of the upper processes folded over the inner surface and connected by a mem- 

 brane which sheathes the penis, as in species of Aphnaeus, Spindasis, Axiocerses, etc. ; penis 

 short and massive, swollen in its internal portion and with obliquely truncate apex ; vesica 

 enclosing numerous long delicate spines ; uncus and distal portions of the valves clothed in 

 fine, delicate hair. 



The male genitalia of sardonyx and argyraspis are of the same type as those of P. 

 thero although the saccus is less developed. The lower fultura is shield-shaped in 

 argyraspis ; but composed of two long digitate processes in sardonyx. 



The early stages of P. thero have been well studied by Gowan C. Clark, 1942,7. ent. 

 Soc. sth. Afr. 5 : 111-115, pi. 3 ; the caterpillar feeds on Rhus longisperma, in 

 association with the ants called " cocktailed ants ".
