GENERA 01 AFRICAN LYCAENIDAE 163 



The caterpillar of C. pseudozeritis tytleri Riley has been described by Jackson 

 (1937, Trans. R. ent. Soc. Lond. 86 : 218). It lives on Acacia stenocarpa Hochst. 

 (ex. A. Rich) (Leguminosae), in symbiosis with ants of the genus Crematogaster.

Genus ZERITIS Boisduval 



Zends Boisduval, 1836, Spec. Gen. Lcp. 1, pi. 22, fig. 6 ; Aurivillius (as a " gen. nov."), 1898 : 

 333 ; 1924 : 417. Type-species : Zeritis neriene Boisduval, by monotypy. Aurivillius, 

 believing Boisduval's Zeritis invalid, re-introduced the name as new. 



Eyes glabrous ; palpi rather short but extending beyond the frons, second segment clothed 

 with long white scales, third segment cylindrical with rounded apex ; antennae about half the 

 length of the costa, club elongated, not well differentiated ; 5* f° re l e f? with tibia shorter than 

 the femur, tarsus unsegmented, finely spinose below. 



Wing shape. Fore wing apex angular, outer margin very convex ; hind wing with two short, 

 delicate tails, at the ends of vein 2 and ib, a small lobe at the anal angle. 



Wing venation (Text-fig. 304). Fore wing with only 10 veins. 



Male genitalia (Text-fig. 146). Uncus composed of two subtriangular rounded lobes ; 

 subunci long, curved, with robust bases, tapering gradually to the apices with, on the inner 

 margin of the basal half, a long apophysis ; tegumen with convex anterior edge ; in situ uncus 

 and tegumen together are hood-shaped ; vinculum rather narrow, prolonged to form a short 

 triangular saccus ; lower fultura fused to the base of the valves, asymmetrical, one branch 

 having a spatulate apex bearing short spines, the other distinctlv longer branch having a slightly 

 serrate edge and tapering gradually to the pointed apex ; valves oblong, their upper processes 

 connected by a membrane as in the preceding genera ; penis long, robust, weakly curved, 

 with an obliquely truncated apex ; vesica containing numerous small cornuti ; uncus and 

 distal portions of the valves pilose. 



The male genitalia of Z. pulcherima resembles so closely those of Z. neriene that 

 one wonders whether these are two species or just two forms of one species, differing 

 only by the markings on the underside of the wings. The male genitalia of Z. 

 sorhageni and fontainei, whilst being of the same type as those of Z. neriene, differ
