mixed with black in middle. Antenna whitish ringed with black, black 
towards base, scape white. Thorax grey in male, white with black apex 
in female. Abdomen pale greyish-ochreous, anal tuft in male whitish. Legs 
whitish, anterior tibia and tarsus black above, white-ringed, median knee 
black, median tarsus dark-ringed. Fore wing elongate, narrow, little 
dilated; costa little curved anteriorly, straight posteriorly; apex rather 
pointed, termen slightly concave, oblique. White, spotted and slightly 
irrorated, especially along markings, with pale ochreous, markings black. 
A narrow transverse streak at base of costa to below fold, a little dilated 
triangularly on costa, angulate and strongly extended posteriorly so as to 
form an equilateral triangular spot: base of this spot along vein lb, top 
of spot to upper edge of cell beyond l / 5 , in male with lower half ferruginous- 
brownish; edge of dorsum, lower edge of triangular spot, and a streak of 
irrorat.ion along dorsum light ochreous; and interrupted irregular light 
ochreous streak from base to 4 / s , less distinct in female ; a curved undulate 
streak from beyond '/ 4 to 3 / 4 of costa, preceded by two black costal points ; 
this streak reaching to lower edge of cell before middle of wing, slightly 
gradually dilated posteriorly, with a small projection below, reaching 
middle of fold, and with a wedge-shaped projection posteriorly just above 
end of cell, running horizontally, in male thicker, less acute; this undulate 
streak is edged below with irregular patches of light ochreous colour, 
largest in middle of streak and at 3 / 4 ; streak ends in an erect-diamond- 
shaped spot on costa, and in male is marbled with dull ferruginous-brownish, 
forming a patch below costa; a small semiovate spot on costa before 
middle, followed by two costal points; a slightly undulate slender preter- 
minal streak, from middle of vein 2, to costa just before apex; on costa 
this streak adorned with a black point, and edged anteriorly with a light 
ochreous suffused spot; this preterminal streak gradually narrowed, lower 
extremity clavate, rounded; termen beyond streak light ochreous; three 
black points on dorsum: at 1 / 3 , at 3 / 5 and at 4 / 5 ; ultimate point somewhat 
erect, sometimes forming an oblique line to lower end of preterminal 
streak; a row of minute black points on veins along terminal edge. Cilia 
white, sometimes tiny black bars on basal half opposite terminal points. 
Hind wing glossy white, faintly tinged greyish posteriorly, short cloudy 
longitudinal grey marks along ends of veins, cilia white. 
Tegumen rather broad, little narrowed above. Uncus small, with a short 
narrow, simple hook. Socius, a minute round knob with two long bristles. 
Hamus, a slender porrect projection, with apex curved laterad. Gnathos 
weak: a pending gradually curved structure, articulations to tegumen 
weak. Transtilla absent. Valva narrow, costa distinct, ending in a bristled 
knob, cucullus very oblique, sacculus over 4 / 2 , terminal knob large, rounded, 
densely covered with modified, short, flattened, bifid bristles. Aedoeagus 
very long, narrow, strongly curved, sinuate towards top. Cornutus, a 
single long spine. Anellus strongly dilated above, encircling aedoeagus.
