[examined] . 

 Zamarada ascaphes Prout; Prout, 1935 : 12. 



$ $ (PI. 98, fig. 873). Hyaline area of each wing irrorate with grey and black, densely at one- 

 third posterior margin of fore wing; postmedial fascia, forming distal margin of hyaline area, 

 black-edged distally with silvery grey, sharply defined and only slightly bowed between veins 

 M 3 and Cu lb ; discal spots silvery grey, that on fore wing ringed with black. Non-hyaline 

 terminal area of each wing greyish yellow densely irrorate with grey and black; subterminal 

 fascia broad and black, ill-defined proximally, dentate distally and edged with silvery grey; 

 termen finely black; cilia chequered greyish yellow and dark grey. Underside of non-hyaline 

 terminal area uniformly grey. 



<$ genitalia (Text-fig. 58). Closely similar to those of pulverosa, differing slightly in the form 

 of the sclerotized projection from the dorsal process of the valve, which is rather more slender 

 and more finely serrate, the tip curved ventrad. 



$ genitalia (PL 13, figs 501, 502). Differs from those of pulverosa in the form of the sterigma, 

 which is longer, being almost as long as broad, and having a concave anterior margin. 



Measurements. Fore wing: $ 10-5-12-5 mm; $ 11-14 mm. Antennal pectinations: <J 10 x, 

 $ 2 X diameter of shaft. 



Distinguished externally from pulverosa by the form of the postmedial fascia, 

 which is markedly less bowed between veins M z and Cu lb and by the shorter antennal 

 pectinations in the female, the longest being twice as long as the diameter of the 

 shaft ; in the female of pulverosa the pectinations are 4-6 times as long as the diameter 

 of the shaft. 



Distribution. South West Africa; Cape Province, Botswana, Rhodesia.
