REVISION OF GENUS ZAMARADA 217 



Distinguished externally from related species by size and combination of 

 yellowish hyaline area and over-all pinkish brown non-hyaline terminal area. 

 Structurally the form of the uncus, ventral plate of the gnathus, the bifurcate 

 valve and the aedeagus with its acicular projection are diagnostic.

Zamarada rupta sp. n. 



(Text-figs 364, 365; PI. 117, fig. 1056) 



(J (PI. 117, iig. 1056). Hyaline area of wings yellowish grey, moderately densely striate 

 with brownish grey, the striae having a purplish tinge in oblique light, and finely edged distally 

 with brown; costa yellowish orange striate with iron-grey; discocellulars brown, that on hind 

 wing slender, that on fore wing ovate and mixed with grey. Non-hyaline terminal area of 

 wings light brown to yellowish brown (pi. 5, D5, clay); dentate subterminal fascia weakly 

 denned in a more orange coloured or darker brown, finely edged distally with glossy buff. 

 Cilia chequered light and dark brown. Underside of non-hyaline terminal area and of disc al 

 spot on fore wing greyish brown. 



O* genitalia (Text-figs 364, 365). Uncus tapered to small, strongly sclerotized point. 

 Ventral plate of gnathus tapered to broadly rounded apex, plate extending to one-half length 

 of uncus. Apex of valve with fractured appearance; apex of dorsal margin curved abruptly 

 ventrad through 90 degrees towards ventral margin and minutely serrate; ventral margin 

 produced beyond level of apex of dorsal margin, strongly sclerotized, spatulate in form and 

 scobinate. Fulcrum similar to that of platycephala, but more extensively and more coarsely 

 scobinate. 



§ unknown. 



Measurements. Fore wing: £ 19mm. Antennal pectinations: rj 9 X diameter of shaft. 



Distinguished externally from platycephala by the more extensive striation of 

 the hyaline area and by the more uniformly coloured non-hyaline terminal area 

 of each wing; distinguished from subincoloris by the dense tuft of brownish grey 

 rather than buff hair-scales on the dilate hind tibia. Structurally the form of 

 the valve in the male genitalia is diagnostic.
