$ Deep-reel {inelining to carmine)^ ivith hlaek spots and horders. 
Fore-iuing : base suffused with black, ratber widely so towards inner 
margin ; costa rather narrowly edged with black ; whole of hind-margin 
with a narrow black border, which emits strongly- marked nervular rays ; ; 
apex also more or less clouded with blackish near the border ; two good- j > 
sized spots in discoidal cell, the outer one touching an oblique black 
mark on costa immediately above it ; a spot, variable in size, at ex- 
tremity of cell ; beyond it, but very close, a rather wide, irregularly- 
shaped, black stripe from costa to near middle of hind-margin, where 
its extremity touches, or almost touches, the first of a row of three spots 
parallel to hind-margin, between third median nervule and submedian 
nervure ; above first median nervule, close to its insertion, a rather 
large, rounded, black spot ; below the same nervule, a little beyond the 
latter spot, a similar, more kidney-shaped spot ; a more or less distinct 
small black spot beyond middle, on inner margin, which is very nar- 
Toiuly edged with black. Hind-iuing : base suffused with black on both 
sides of median nervure; about twelve rather small, round, black spots 
in hasal half of wing^ the outer seven or eight of which form a sinuated 
transverse row ; a curved black streak at upper portion of extremity 
of discoidal cell ; hind-margin with a moderately broad black border, 
unspotted, which radiates strongly upon nervules. Under side. — Paler 
and didler than upper side. Fore-wing : dull, creamy salmon-red ; a 
small black mark on costa at base, but no black suffusion ; two spots ^ 
nearest to base wanting ; the other spots similar in number and arrange^ I 
ment, but dull-blackish ; an additional small black spot just below . ■ 
median nervure, before middle; beyond the blackish stripe a small 1 
space clouded with whitish; no black border on hind-margin, but the 
nervules are clouded with dark-grey near it, and there are broad, reddish- | 
ochre rays between the nervules all along hind-marginal border. Hind- « 
iDing : reddish-white ; black spots as on upper side, but three or four 
more visible close to base, all very conspicuous ; interspersed among the 
spots several pale-reddish marks ; hind-marginal band blackish, radiat- 
ing in dark-grey on the nervules, and containing seven elongate, yel- 
lowish or yellowish-white spots, between nervules, along its outer 
portion ; immediately within band a row of elongate, wedge-shaped, 
reddish-ochre marks between nervules. 
$ Fer?/ different from ^, varying in ground-colour from dull-red to 
dull-greyish or ochreoics-hroiun, and even to hroiunish-fuscous. Fore-wing :
