GENERA OF AFRICAN LYCAENIDAE 

 Genus COOKSONIA H. H. Druce 



13 



Cooksonia II. H. Druce, 1005. Trans, ent. Soc. Lond. 1905 : 256 ; Aunvilln.s. 1914-1925 : 302. 



Tvpe-species : Cooksonia trimeni H. II. Druce, 1905. by original designation. 

 Sheffieldia II H Druce, .-,12, Entomologists num. Mag. 48 : 128 ; Talbot, 1935. Entomologist's 



mm. Mag. 71 : 202, synonymy. Type-species : Sheffieldia neavei H. H. Druce, by monotypy. 



s smooth palpi of medium length, erect, clothed with adpressed black scales, third 

 segment very short ; antennae slender, half as long as costa ; club well differentiated, flattened, 

 spatulate. 



Wing venation (Text-fig. 231). 



The only known specimen of C. trimeni is a $, so I have been unable to examine the 

 <J genitalia of the type-species ; on the other hand, I have examined the $ genitalia 

 of C. neavei H. Druce and C. aliciae Talbot. 



In C. neavei the <J fore legs are short, almost glabrous, tibia a trifle shorter than the 

 femur, tarsus unsegmented and bearing fine spines below. The venation (Text-fig. 

 232) of C. neavei differs slightly from that of C. trimeni inasmuch as wins 5 and 6 of 

 the fore wing have a short common stem which arises from the upper angle oi the 

 cell, but this difference is not constant, for I have seen in the British Museum a £ 

 specimen of C. neavei in which the veins arise as in C. trimeni. The synonymy given 

 by Talbot, viz : Cooksonia = Sheffieldia, is undeniable.
