REVISION OF AFRICAN SPECIES OF CLEORA 69 



melanic form appeared to me to have considerable cryptic advantage. I would say 

 that the melanic form was between 4 and 10 per cent, of the population over the 

 the period I collected ." 



The species is closely related to thyris, nigrisparsalis and to the following species, 

 munda ; in the male genitalia the shapes and sizes of the medial plate of the gnathus 

 and of the process on the sacculus and the shape of the broadly spatulate cornutus 

 on the vesica are diagnostic ; in the female genitalia the shape of the sclerotized 

 parts of the sterigma, the colliculum and the bursa copulatrix are diagnostic. 



Distribution (Map 4). Kenya ; Zambia ; Mozambique ; Transvaal ; Natal ;
