spatulate apex, incurved through 90 degrees towards the uncus. The dorsal 

 process is dilate and setose in its basal fourth, the dilation smooth or irregular 

 in outline, but never digitate in form. The fulcrum is slender, never broader 

 than one-half of the greatest width of the aedeagus and, except in auratisquama, 

 about twice as long as the aedeagus. The uncus is long, slender and tapered. 

 The ventral plate of the gnathus is weakly sclerotized, broad, deep and minutely 

 scobinate. The aedeagus is short and stout, with or without coarse scobination 

 on one surface. Vesica without cornutus. 



The male hind tibia is dilate, enclosing a dense tuft of long hair-scales. 



In the female genitalia the posterior margin of the lamella antevaginalis is 

 irregularly serrate, as in the metrioscaphes-group, but usually more strongly 

 developed on the right side; lamella post vaginalis also similar to those of the 

 metrioscaphes-group, medially rugose with a series of closely adpressed, concentric 

 folds. 



Key to Species 



1 Aedeagus coarsely scobinate on one surface in apical third ... 2 

 - Aedeagus smooth ........... 3 



2 (1) Fulcrum subequal in length to aedeagus . . . auratisquama (p. 206) 



Fulcrum one and three-fourths as long as aedeagus . . acrochra (p. 205) 



3 (1) Non-hyaline terminal area uniformly fawn coloured, without subterminal 



fascia. Distal margin of hyaline area smoothly curved without marked 

 excavation of terminal area between veins M 3 and Cu lb (PI. 115, fig. 1044) 



clenchi (p. 204) 

 Non-hyaline terminal area not so coloured and deeply excavate between 



veins M s and Cu lb ; subterminal fascia present ..... 4 



4 (3) Hyaline area of wings without discal spots. Non-hyaline terminal area 



deeply excavate on each wing between veins M 3 and Cn lb , the hyaline 

 extending almost to termen on hind wing (PI. 115, fig. 1043). Greatest 

 width of dilate hind tibia equal to one-fifth of its length. Basal projection 

 from dorsal process of valve irregular in outline . . enippe (p. 203) 



Slender, grey discal spots present on each wing. Non-hyaline terminal area 

 excavate to one-half of its width between veins M 3 and Cw lb . Greatest 

 width of dilate hind tibia one-half of its length. Basal projection from 

 dorsal process of valve smooth in outline .... dilata (p. 202) 



Zamarada dilata sp. n. 



(Text-figs 333, 334; PI. 72, figs 739, 740; PI. 115, fig. 1042) 



<£$ (PI. 115, fig. 1042). Hyaline area of wings tinged with yellow and finely edged distally 

 with dark brown; costa of fore wing buff irrorate with dark grey medially, densely with pearly 

 grey at base; posterior margin of each wing irrorate with pearly grey; discocellulars slenderly 

 pearly grey. Non-hyaline terminal area of each wing brownish orange (pi. 7, C5) to light 

 brown (pi. 7, D5) sparsely irrorate with dark brown; dentate subterminal fascia broken, 

 dark brown edged distally with a few glossy buff scales; cilia chequered dull buff and grey. 

 Underside of non-hyaline terminal area of each wing dark brown proximally, markedly paler 

 terminally; apical area of fore wing light buff sparsely irrorate with brown; cilia chequered 

 brown and grey.
