REVISION OF GENUS ZAMARADA 129 



ilaria being 13 x , those of erato being 14 x the diameter of the shaft, the pectinations 

 of erato are appreciably longer, its shaft being broader. 



In the male genitalia ilaria is readily distinguished by the broader apex of the 

 valve and the stouter thorn-like lateral projection from the aedeagus. The female 

 genitalia of the two species do not appear to differ. 



Distribution. Guinea, Sierra Leone, Liberia, Nigeria, Cameroun.

(BMNH), here designated [examined]. 

 Zamarada erato Oberthur; Gaede, 1915 : 116. 



$ 9 (PI- io 7- n S s 958' 959)- Differs externally from ilaria in the longer pectinations of the 

 male antennae, in the paler, brighter, greyish orange colour of the non-hyaline area of the 

 upperside of the wings and in the less extensive dark suffusion of the corresponding areas of 

 the underside. 



O* genitalia (Text-figs 217, 218). Differ from those of ilaria in the narrowly rounded apex 

 of the valve and in the reduced size of the thorn-like lateral projection from the aedeagus. 



The female genitalia do not appear to differ from those of ilaria. 



Measurements. Fore wing: $ $ 14-16 mm. Antennal pectinations: $ 14 X [10 : 0-7], 

 $ 8 X diameter of shaft. 



Distribution. Cameroun.
