GENERA OF AFRICAN LYCAENIDAE 



165 



hair ; legs short, rather robust ; <J fore leg with femur clothed with white hairs, tibia shorter 

 than femur, tarsus rather long, unsegmented, bearing long spines below. 



Wing shape. Fore wing with apex angular ; hind wing with a small filiform tail at the end 

 of vein ib. 



Wing venation (Text-fig. 305). Fore wing with 11 veins ; 11 free, but very close to the 

 costal vein and sometimes in contact with it. As in Chloroselas, variations in the venation are 

 not rare. Riley cited examples in his original description of rogersi. 



Male genitalia (Text-fig. 147). The o* genitalia of D. mazoensis are very similar to those of 

 Chloroselas esmeralda, except that the lateral margins of the uncus are not serrate and the apical 

 depression is rounded instead of triangular ; the subunci are a little shorter and the vesica 

 has no cornuti. 



The male genitalia of D. arabica are almost identical with those of D. mazoensis. 

 On the other hand, those of D. rogersi (Text-fig. 148) differ' considerably ; the 

 dorsum is rectangular instead of oval and the subunci are reduced to two rudiments ; 

 the inferior fultura, valves and penis are as in D. mazoensis. By the structure of the 

 genitalia as well as by the markings of the wings, the species of the genus Desmoly- 

 caena are closelv allied to those of Chloroselas.
