$ 17.5 mm. Head and thorax snow-white, the latter with a narrow 
angulate dark grey transverse streak. Palpus dark fuscous at base and 
below, upper half of median segment and terminal segment throughout 
snow-white. Abdomen whitish-ochreous. Legs dark fuscous, white-ringed, 
posterior leg white above. Fore wing with veins 3 and 4 remote; narrowly-

glossy; a rather large basal patch, brownish-black on costa and along both 
vertical edges, turning olive-greenish in middle and on dorsum; its outer 
edge sharply defined, running from costa beyond J / 6 obliquely to dorsum 
before base, edged in middle by raised white scales; a large brownish-black 
invert-trapezoid patch along middle half of costa reaching halfway across 
wing, with edges very oblique, anterior edge ending below in a large 
rounded spot of raised scales reaching to fold ; posterior margin ends below 
in a short transverse streak, and is edged posteriorly throughout by a ridge 
of raised white scales; a small triangular dorsal patch before end of fold 
opposite this ridge, somewhat lighter olive-brownish, with bronze gloss 
along lower half, except along vertical edges; a moderate subquadrate 
blotch on costa at 4 / 6 , followed by a smaller blotch, both connected with 
tornus by a furcate transverse little oblique suffused fascia, which is 
dilated above and furcate below costa; apical and terminal edge with a 
series of brownish- black streaks; a round patch of raised white scales 
below 2 / 5 of fold. Cilia leaden-grey, dark grey at apex, basal half suffused
