The palpi are short and thin, but distinct. The antenne are 
short, each joint emitting four rays lying flat. 
The specimen in the British Museum collection is pale russet- 
coloured beneath with a pinkish bloom, the centre of each wing with 
a group of brown spots much larger im the hind- than in the fore- 
wings; a small brown spot also occurs at the base of the hind- 
wings.

The fore-wings are pale greyish-brown, sometimes with a reddish 
tinge ; they are acute at the tip in both sexes, but the outer margin - 
is considerably more emarginate than in the female; the base of the 
wing is red, and near the base is a red, very much angulated striga 
almost suffused into the ground colour of the wing, and outwardly 
edged with a slight dusky striga; across the middle of the wing is a 
waved but nearly obsolete striga, and in the middle of the wing to- 
wards the fore-margin is a small subtriangular vitreous spot without 
any appearance of ocellus: beyond the middle is a row of reddish 
arches inwardly slightly edged with a thin dusky line. 
The hind-wings are redaish, with a broad pale greyish-brown border ; 
in the middle of the wing is a large round black spot, with a very 
small vitreous lunar spot in the middle, preceded snd followed by a 
slight dusky waved striga. The body above is of the ground colour 
of the wings, with the hind part of the thorax marked with red. 
The underside of the body, collar, and spot at the base of the hind- 
wings are white. The head, antennz and legs dark brown. 
The wings beneath are very pale buff,with the centre of each 
marked by a large brown irregular spot, traversed by the pale veins. 
Antenne of the male with 32 rays on each side (four from each 
joint). One-third of the apical part of each antenna is destitute of 
rays. 
The antennee of the female are slightly pectinated for two-thirds of 
the base, the two apical rays of each joint being almost obsolete. The 
tips are serrated. 
The palpi are deflexed, and the tips appear just beyond the hairs 
of the lower part of the face. 
Var. Smaller, with the fore-wings and body destitute of the red 
colour, and the hind-wings fulvous with the outer margin purplish- 
grey, with the eye as in the others.
