Cj genitalia (PI. 85, figs 794, 795). Lateral and posterior margins of lamella antevaginalis 

 crenulate and coarsely scobinate, posterior margin incised medially at operculum. 



Measurements. Fore wing: <§ 9 17mm. Antennal pectinations: J $ 11 x diameter of 

 shaft. 



Externally distinct in both colour and pattern. In the male genitalia the form 

 of the apical extensions of the bifurcate valve are diagnostic; in the female genitalia 

 the crenulate and coarsely scobinate sterigma is strikingly formed and, when 

 those of the other species in the group are known, may prove to be specifically 

 diagnostic.

Zamarada erosa sp. n. 



(Text-figs 411, 412; PI. 85, figs 796, 797; PI. 120, fig. 1077) 



(J$ (PI. 120, fig. 1077). Hyaline area of wings tinged with greenish yellow and sparsely striate 

 with grey; distal margin of area broadly excurved between veins M 3 and Cu lb and finely edged 

 with black; discocellulars grey, slender on hind wing, ringed with dark grey on fore wing. 

 Non-hyaline terminal area of fore wing and anterior half of that area on hind wing greyish 

 brown to light brown (pi. 6, D3-D4) ; posterior half of non-hyaline terminal area on hind 

 wing greyish buff; subterminal fascia light brown (pi. 6, D6, cinnamon) edged distally with 

 black, heavily marked between costa and vein M 2 on fore wing, and finely with silvery grey, 

 the silvery grey suffusing to termen on fore wing between veins M 3 and Cw la . Underside 

 of non-hyaline terminal area greyish brown, posterior half of hind wing a little paler. 



The male hind tibia is dilate enclosing a tuft of hair-scales little longer than the width of 

 the tibia; similar to those found in the metrioscaphes-gToup. 



$ genitalia (Text-figs 411, 412). Closely similar to those of crenulata, differing in the longer 

 extension of the dorsal margin of the valve, being equal in length to that from the ventral 

 margin, in the larger setose projection from near the base of the dorsal process of the valve 

 and in the differently shaped fulcrum. 



9 genitalia (PI. 85, figs 796, 797). Lamella antevaginalis ridged laterally and minutely 

 scobinate along posterior margin. 



Measurements. Fore wing: $ i8-5-2i-o mm; $ 18-19 mm. Antennal pectinations: (Jiox, 

 $ 9 X diameter of shaft. 



Distinguished externally from triangularis, amymone and crenulata by wing 

 pattern, which is reminiscent of collarti in the perlepidata-gvonp and of reflexaria 

 apsis in the reflexaria-group, with which it occurs in western Kenya. Distinguished 

 from both by the greater wing-span and lack of dark striation of the hyaline area; 

 from collarti further by the presence of a pocket of hair-scales on the male hind 

 tibia and from reflexaria apsis by the shorter hair-tuft on the male hind tibia and 

 by the presence of a well-developed discal spot on the hind wing. In the male 

 genitalia the form of the valve and of the fulcrum are diagnostic; in the female 

 genitalia the form of the sterigma appears to be distinctive. 



Three examples from Uganda, Cameroun and Nigeria have a shorter wing-span
