n8 P. E. S. WHALLEY 



genus has not been recognized outside Africa south of Sahara and does not occur in 

 Madagascar. 



Generic description. Labial palps 3-segmented. Antennae shortly ciliate. Eyes with- 

 out interfacetal hairs. Proboscis present. Epiphysis on fore tibia. Hind tibia with two pairs 

 of spurs, proximal spur often slightly clavate. Tarsi without spines. Black and silver scales 

 forming patches under fore wing. Radial veins from cell (except K. kibala). Uncus of male 

 simple or modified. No signum in bursa in female. 



Biology. No information. Some evidence from localities suggest that the 

 species are primarily forest-dwelling. 



The two species-groups are separated on wing shape and genitalia. The 

 GEMMATA -group: Apex of fore wing pointed. Terminal margin sinuous. Uncus 

 with broad lateral expansions. 



The SQUAMIGERA -group: Apex of fore wing rounded. Uncus usually simple, 

 if slightly expanded laterally, termen never sinuous. 



The two species-groups are included together in the following key. 



Key to the African Species of KUJA

- Grey-brown median and basal areas. Subapical line narrowing at terminal 



margin. Genitalia as in PL 37, fig. 208 . . . . obliquifascia (p. 122) 



The GEMMATA -Group 



This contains the two closely related species, gemmata and catenula. Externally 

 they are very similar but catenula tends to be a lighter coloured species than 

 gemmata and there are differences in the genitalia. This group is separated from 

 the squamigera-gronp by the shape of the termen of the fore wing and the presence 

 of the strong lateral processes on the uncus of the male.
