i°5 



slender, with an elongate fusiform club ; o" fore leg, femur clothed with long white hairs, tibia 

 shorter than the femur, tarsus unsegmented, clothed below with stiff hair. 



Wing shape. Fore wing inner margin slightly lobed in its basal portion. Male secondary 

 sexual characters : on underside of fore wing in the basal half a silkv, shining patch which is 

 silvery between veins 1 and 2 and violet-black between veins 2 and 3 ; on the inner margin a 

 tuft of long black hairs directed towards this patch ; on upperside of hind wing a small whitish 

 spot near the origin of vein 8 and, along vein 2, a tuft of very long black hairs directed towards 

 the anal margin. 



Wing venation (Text-fig. 280). l r ore wing with 11 veins ; veins 10 and 11 free. 



Male genitalia (Text-fig. 97). Uncus composed of two lobes separated by the rounded depres- 

 sion of the posterior edge of the tegumen ; subunci long and bent about mid-length ; tegumen 

 very large, hood-shaped ; vinculum narrow ; no lower fultura ; valves oblong, fused at the 

 base, distal half digitate, upper edges folded in and connected by a membrane which surrounds the 

 penis ; penis elongate, subcylindrical, the external portion much shorter than the internal 

 portion ; vesica enclosing an enormous cuneus ; uncus and apices of valves pilose. 



The male genitalia of all the species of Pilodeudorix that I have examined are very 

 similar to those of camerona, described above. 



The caterpillars of P. camerona and P. diyllus live among ants on flowers of 

 Pterocarpus escidentus Schumach (Leguminosae), see Farquharson, 1922, Trans, 

 ent. Soc. Lond. 1921 : 381.
