along posterior margin, and finely edged distally with black and silvery grey; discal spots 

 grey, that on fore wing heavily outlined with a darker shade. Non-hyaline terminal area 

 light brown (pi. 5, D5, clay), greyer proximad of the darker brown, dentate subterminal fascia, 

 which is edged distally with light buff; darker brown also in apical area of each wing and in 

 tornal area of hind wing. In some examples the non-hyaline terminal area is suffused with 

 greyish brown and the subterminal fascia marked in a darker grey. 



2. The paler part of the non-hyaline terminal area, that is between veins M 3 and C« lb 

 on the fore wing and posterior of vein M 3 on the hind wing, is usually greyish orange, contrasting 

 more markedly with the darker areas, and the subterminal fascia is usually poorly defined. 



Underside of non-hyaline terminal area and discal spots in both sexes dark brown. 



<J genitalia (Text-figs 349, 350). Uncus almost square, truncate apex equal in width to 

 base; apical margin sometimes slightly crenulate. Ventral plate of gnathus similar to that 

 of principis but broader, posterior margin sometimes shallowly excavate medially. Valves 

 symmetrical; ventral and dorsal margins produced and tapered, apex of dorsal margin acicular 

 and curved towards uncus. 



2 genitalia (PL 74, figs 747, 750, 751; PI. 75, fig. 756). Sterigma usually conspicuously 

 crenulate laterally. Posterior margin of lamella postvaginalis shallowly and broadly excavate, 

 laterally straight or convex. Lamella antevaginalis variable in form. 



Measurements. Fore wing: $ 15-18 mm; 2 13-17 mm. Antennal pectinations: £ 13 X, 



2 2 X diameter of shaft. 



Structurally closely akin to principis; distinguished in the male genitalia by the 

 form of the uncus, ventral plate of the gnathus and by the form of the valve, the 

 dorsal margin of which is tapered apicad to a single spine incurved towards the 

 uncus. The female genitalia are closely similar to those of principis, differing in 

 the grosser lamellae; the lamella postvaginalis extends almost as far posteriorly 

 as the crenulate lateral margins of the sterigma and its posterior margin is more 

 deeply recessed.

Zamarada tricuspida sp. n. 



(Text-figs 351, 352; PI. 117, fig. 1055) 



<§ (PI. 117, fig. 1055). Externally similar in colour and pattern to female specimens of 

 platycephala with well contrasted paler, orange-grey areas in the otherwise dark non-hyaline 

 terminal area on the fore wing distad of the subterminal fascia between veins M 3 and Cu lb 

 and on the hind wing posterior of the fold representing vein M 2 and at the anal angle.
