GENERA OF AFRICAN LYCAENIDAE 139 



Male genitalia (Text-fig. 124). Uncus composed of two triangular lobes with rounded 

 apices ; subunci long, obtuse angled, robust at the base and tapering gradually to the apex ; 

 tegumen large ; in their normal position uncus and tegumen together are hood-shaped ; 

 vinculum wide above, narrow below, no saccus ; lower fultura consists of a ring, which closely 

 encircles the penis, and is borne on a long peduncle fused to the point of origin of the valves ; 

 valves oblong, slightly falcate at the apices, the upper process bearing distally a lobe folded 

 back on the valve ; penis long, robust, internally widely open dorsally, external portion tapering 

 gradually to the apex ; vesica enclosing two large cunei, (exserted in the figure) ; uncus densely 

 hairy, only a few hairs on the apices of the valves. 



The genitalia of bolissus and carina only differ from those of eurisus in certain 

 details of the shape of the valves.

IOLAUS (EPAMERA) H. H. Druce 



Epamera H. H. Druce, 1891, Ann. Mag. nat. Hist. (6) 8 : 139. Type-species : Iolaus sidus 



Trimen, by original designation. 

 Iolaus Hiibner (partim) ; Aurivillius, 1898 : 325, 326 ; 1923 : 394 ; 1924 : 397 ; Murray, 



1935 : 7 6 I Swanepoel, 1953 : 173. 



In his description H. H. Druce gave the following generic characters : " Allied to 

 Iolaus, smaller. Venation the same. Fore-wing below without the thick patch of 

 scales above the tuft of hairs on the inner margin. Head broader, antennae shorter, 

 stouter and less distinctly clavate ". However, with the exception of the venation, 

 it is necessary to state that none of the other generic characters given is to be found 

 in every one of the species generally placed in Epamera. In size the species of the 

 laon group are at least as large as those of typical Iolaus ; but it is true that most of 

 the species of Epamera are small. The length and the shape of the antennae seem 

 to vary from species to species, though only slightly. In no case do they show any 

 striking peculiarities. As in all species of the large genus Iolaus the fore tarsi of 

 the <J are unsegmented.
