Zamarada consummata (Prout MS) sp. n. 

 (Text -figs 360, 361; PI. 116, fig. 1045) 



^ (PI. 116, fig. 1045). Similar in colour and pattern to bicuspida, with which it flies in 

 Cameroun; distinguished by its larger size and broader intrusions of hyaline into the non- 

 hyaline terminal area of each wing, characters more marked in Congo and Uganda specimens 

 than in those from Cameroun. 



^ genitalia (Text-figs 360, 361). Closely similar to those of bicuspida, differing in the form 

 of the valve: the ventral margin is evenly curved towards the dorsal margin, the latter excavate 

 just below the apex, which is short and smoothly acicular.

Zamarada onycha sp. n. 



(Text-figs 362, 363; PL 117, fig. 1053) 



(J (PI. 117, fig. 1053). Hyaline area of wings tinged with yellow and finely edged distally 

 with dark brown; costa and posterior margin of fore wing yellow striate with brownish grey, 

 more densely on costa; discocellulars finely yellow, those on fore wing edged with brownish 

 grey. Non-hyaline terminal area brownish orange (pi. 5, C5-C6) tinged with reddish grey 

 proximad of the dentate subterminal fascia, which is weakly marked in a dark shade of brownish 

 orange and slenderly edged distally with glossy buff. Underside of discal spot on fore wing 

 and of non-hyaline terminal area brown, the latter becoming paler terminad and tinged with 

 yellow at anal angle of hind wing. 



$ genitalia (Text-figs 362, 363). Uncus tapered to rounded apex, from which a short, 

 blunt projection extends ventrad. Ventral plate of gnathus tapered to narrowly rounded 

 apex, extending almost to tip of uncus. Apex of valve bifurcate; apex of ventral margin 

 acutely angled or rounded, apex of dorsal margin produced in digitate form. Aedeagus finely 

 tapered and blade-like with an acicular projection at one-third, the projection one and one-half 

 times as long as greatest width of aedeagus. Fulcrum stout, apex curved and scobinate, 

 extending over and beyond tip of aedeagus. 



^ unknown. 



Measurements. Fore wing: <$ 20 mm. Antennal pectinations: $ 7*5 X diameter of shaft.
