Genus CHLOROSELAS Butler 



Chloroselas Butler, 1886, Proc. zool. Soc. Lond. 1885 : 765 ; Aurivillius, 1898 : 323 ; 1923 : 416 ; 

 Murray, 1935 : 90 ; Swanepoel, 1953 : 168. Type-species : Chloroselas esmeralda Butler, 

 1886, by original designation. 



Eyes glabrous ; palpi long, reaching beyond the irons, second segment ascending, wider 

 and more curved than in Spindasis, clothed below with large erect scales, third segment hori- 

 zontal, shorter than in Spindasis, clothed with adpressed scales ; antennae more slender than 

 those of Spindasis, with a better differentiated, fusiform club ; thorax clothed below with 

 white hair ; abdomen white-annulated ; <J fore leg more slender than in Spindasis, tibia shorter 

 than the femur, tarsus long, unsegmented, spinose below. 



Wing shape. Hind wing produced at the anal angle, a delicate tail at the end of ib (in 

 pseudozeritis, overlaeti, azurea and taposana there is also a short delicate tail at the extremity 

 of vein 2), an indistinct lobe at the anal angle. 



Wing venation (Text-fig. 303). Fore wing with 10 or 11 veins ; vein 11 is sometimes absent 

 entirely ; when present, it is reduced to a short stalk joining the upper margin of the cell to 

 the costal vein ; veins 6 and 7 are also sometimes slightly stalked. Individual variations of 

 this kind are frequent. 



Male genitalia (Text-fig. 145). Dorsally similar to Lipaphnaeus, except that the apex of the 

 uncus is less deeply divided and the lateral margins are serrate ; subunci long, evenly curved 

 and tapering ; tegumen reduced, intimately fused to the uncus but not with the vinculum ; 

 vinculum narrow with a subtriangular saccus ; lower fultura shield-shaped, with deeply 

 notched apex ; valves oblong with blunt apices, their basal thirds fused together, the upper 

 processes connected midway by a membranous band which surrounds the penis as in the 

 preceding genera ; internal portion of penis ovoid, the external portion cylindrical with an 

 obliquely truncate apex ; vesica with large cornuti ; uncus and distal extremity of valves 

 pilose. 



The male genitalia of pseudozeritis, overlaeti, argentea and azurea closely resemble 

 those of C. esmeralda, and in the first three the vesica encloses a sheaf of long, fine 

 spines ; in azurea the external portion of the penis is slightly shorter and the vesica 

 and devoid of cornuti.
