segment greyish-white, with a blackish median ring. Thorax whitish-grey 
suffused with light bronze-fuscous. Abdomen dark grey, anal tuft pale 
greyish-ochreous. Legs grey, articulations of segments and a median band 
on tibia whitish, posterior tibia greyish-white above, spurs glossy white. 
Fore wing lanceolate, moderate, costa gently curved, a small projection 
of cilia before middle, a larger one at 3 / 4 of costa, apex pointed, termen 
very oblique. Greyish-white, densely irrorated throughout and towards 
base suffused with bronze-grey-fuscous. A very ill-defined broad direct 
transverse band of coarse greyish-white irroration, dilated towards dorsum 
and extended anteriorly along edges of wing to before its middle. Other 
markings blackish: a narrow moderate strigula along fold from beyond 
base, sometimes absent ; a cloudy dot below costa before middle of wing, 
another well defined, somewhat smaller dot in fold below and beyond 
preceding, sometimes reduced to a small longitudinal streak; one or two 
short horizontal streaks in middle of disc posteriorly; a longitudinal 
blotch of coarse black irroration along posterior fifth of costa, reaching 
halfway across wing and emitting a rather irregular curved line across 
middle of cilia, reaching as far as tornus; otherwise cilia before median 
fine whitish, speckled with black, beyond it greyish-fuscous; a basal patch 
of black irroration opposite tornus, dorsal cilia fuscous-grey. Hind wing 
and cilia fuscous-grev. 
Uncus with claw-like lobes. Socius, a series of three minute bristles. 
Gnathos, a moderate round bristly knob with a transverse sclerotized 
fold at base. Valva elongate, rather slender, costa with a moderate blunt 
projection beyond middle. Cucullus with a rather stout, subacute spike. 
Sacculus with a short process at base, weakly bristled apically. Anellus 
broad below, apical lobes rather broad and long. Saccus erect-triangular, 
long. Aedoeagus long, slender, base bulbate. (Slide no. 1053 D, holotype.)
