H. STEMPFFER 



Wing venation (Text-fig. 287, Hypolycaena sipylus). Fore wing with only 10 veins. 



Male genitalia (Text-fig. 105). Uncus formed of two roughly oval lobes ; subunci long and 

 slender, evenly curved ; tegumen formed by a simple enlargement of the vinculum ; in the 

 natural position the tegumen and uncus form a hood-like structure ; vinculum very wide, with 

 a short rounded saccus ; inferior fultura absent ; valves small in relation to the dorsal elements, 

 elongate with a slightly recurved tip, tapering, the upper margin bearing a rounded expansion, 

 which represents the second point of attachment, and joined to the vinculum by a membrane ; 

 penis elongate, basally swollen, dilated distally, vesica enclosing very small cornuti which give 

 it a shagreened appearance ; uncus and distal portion of valves pilose. 



The male genitalia of the African species of Hypolycaena are of the same pattern 

 as those of H. sipylus, which is an Indo-Malayan species. The valves are always 

 rather small in relation to the dorsal elements, but they are generally less elongate 

 and more massive than in sipylus ; the lobes of the uncus are oval, with rounded 

 apices ; the subunci are of the sipylus type in pachalica, antif annus, lebona and 

 liara ; in naara they bear a small apophysis at the point of maximum curvature, and 

 the apophysis is much more developed in hatita, buxtoni, amanica, jacksoni, nigra, 

 kadiskos, philippus, and auricostalis. However, I do not attach any considerable 

 taxonomic importance to the presence or absence of this apophysis, which also 

 occurs in certain species of Deudorix. I figure it only in antifaunus (Text-fig. 106) 

 and nigra (Text-fig. 107). 



As I have pointed out in my original description, ogadenensis has male genitalia 

 of a type very different from those of the other species of this genus. I have only 

 placed this species in the genus Hypolycaena temporarily, on the basis of its wing 

 venation, until I can study further material. 



The larvae of nigra, philippus and lebona have been described by Lamborn (1911, 

 Proc. ent.Soc. Lond. (C), and 1913, Trans, ent. Soc. Lond. 1913 : 473), by Jackson 

 (1937, Trans. R. ent. Soc. Lond. 86 : 213) and by Pinhey (1949 : 101). They are 

 onisciform and are tended by ants of the genera Pheidole and Camponotus.
