GENEK \ OF AFRICAN LYCAENIDAE 127 



Wing shape. Fore wing inner margin with a large basal lobe ; hind wing outer margin with 

 a marked angle at the end of vein 3, two delicate tails 4-5 mm. long, at the ends of veins 2 and 

 ib, a small anal lobe. Male secondary sexual characters : on the upperside of the hind wing 

 there is an androconial patch, about 3 mm. wide, at the origin of vein 7, surrounded by a white 

 pearly zone which extends into the cell ; on the underside of the fore wing, level with the lobe 

 of the inner margin, there is a tuft of long hairs directed towards the androconial patch on the 

 hind wing. 



Wing venation (Text-fig. 291). Fore wing has only 10 veins. 



Male genitalia (Text-fig. 112). Uncus composed of two lateral strips separated by the 

 depression of the margin of the tegumen ; subunci strongly curved, very robust at the base 

 and then tapering uniformly ; tegumen large and hood-shaped ; vinculum rather broad above, 

 narrow below ; lower fultura pedunculate and bearing a complete ring which encircles the 

 penis ; valves oblong, apex divided into two sharp-pointed teeth ; penis elongate, robust, 

 slightly curved ; vesica enclosing two strong recurved spines ; uncus and distal portion of valves 

 densely hairy. 



The male genitalia of lulua are very similar to those of poultoni. 



The subgenus Pseudiolaus is easily distinguished from the subgenus Stugcta by the 

 more slender antennae, and in the male by the presence of secondary sexual charac- 

 ters ; the general appearance and wing markings of Pseudiolaus remind one of the 

 subgenus Epamera.

IOLA US (TRICHIOLA US) Aurivillius 



Trichiolaus Aurivillius, 1898 : 317 ; 1923 : 389. Type-species : Hypolycaena mermeros 

 Mabille, designated by Stempffer & Itennett, 1058 ; [276. 



Eyes densely hairy ; palpi extending considerably beyond the Irons, second segment very 

 long and clothed with adpressed scales, third segment very short, conical ; antennae with a 

 gradually swollen, fusiform club ; thorax clothed below with grey silky hairs ; <J fore leg, 

 femur clothed with long grey hairs, tibia as long as the femur, tarsus unsegmented, robust, 

 finely spinose below. 



Wing shape. Hind wing oval, somewhat produced at the anal angle, outer margin slightly 

 angular at the end of vein 4, a short pointed tail at the end of vein 3, a longer delicate tail at 

 the end of vein 2, a still longer tail at the end of vein ib, a lobe at the anal angle. Male 

 secondary sexual characters absent. 



Wing venation (Text-fig. 292, o"). Fore wing, <J with 12 veins, ? II. 



Male genitalia (Text-fig. 113). Uncus composed of two large semicircular lobes ; subunci 

 long and curving ; tegumen rather large, but narrow in the median area ; vinculum broad 

 dorsally, narrow ventrally ; inferior fultura like a furca with divergent arms ; valves oblong 

 with rounded apices ; penis elongate, widely open on the upper surface of almost the whole 

 of the internal portion, the external portion very short with bulbous apex ; vesica appearing 

 shagreened ; lobes of uncus and distal portion of valves hairy. 



The male genitalia of /. {Trichiolaus) argentarins are almost the same as those of 

 /. {Trichiolaus) mermeros, only the valves are a little narrower.
