densely mixed with dark brown, cilia dark brown, terminal segment dark 
brown, tip pale ochreous. Antenna fulvous above, pale ochreous below. 
Abdomen light ochreous suffused with grey. Fore wing elongate, narrower 
than in male, costa gradually and obliquely curved anteriorly, projecting 
and with a brush of moderate cilia in middle, concave posteriorly, apex 
subacute, termen hardly concave, more oblique than in male. Light 
tawny-fulvous, partially pale ochreous, markings lilac-ferruginous. Basal 
patch large, edge very oblique, from 1 / 6 of costa to dorsum before middle; 
this patch lilac-ferruginous, darkest on dorsum, upper third obliterate, 
with a faint mark on costa indicating edge of patch, and with a dark 
ferruginous-brown dot below this mark just above cell; central fascia 
from 2 / 5 of costa to posterior half of dorsum : lilac-ferruginous, somewhat 
paler above middle of wing, curved and dilated below; anterior edge of 
fascia from before 1 / ;l of costa to middle of dorsum, slightly sinuate, 
excavate below fold; posterior edge of fascia suffused, from before 2 / 5 of 
costa to tornus, with upper third concave, lower 2 / 3 broadly obliquely 
rounded; space between basal patch and central fascia pale ochreous, 
irrorated with ferruginous-brown scales; costal patch large, rather dark 
lilac-ferruginous, from beyond 3 / 5 of costa to apex, finely transversely 
strigulated with deep brown ; anterior edge of patch slightly convex below' 
costa, becoming gradually concave, and tolerably parallel to posterior 
edge of central fascia below this edge, running to termen above tornus; 
posterior edge of patch indent, enclosing a triangular spot of more or less 
suffused ground colour on upper half of termen ; this spot reaching above 
as far as vein 7, finely transversely strigulated with dark brown. Cilia 
white, opposite apex and tornus suffused with dark grey, an antemedian 
row of dark brown quadrate dots. Hind wing pale whitish ochreous, apex
