Male with the fore-wings very slightly emarginate along the outer 
margin; hind-wings produced into a strong angle in the middle of 
the hind-margin ; all on the upper side of a silky, pale brownish-grey, 
uniform colour, traversed by a slightly distinct, slender, brown striga 
‘beyond the middle. The hind-ones marked moreover in the middle with 
asmall, round, dusky spot, having an indistinct vitreous lunule in the 
middle, and surrounded by an indistinct whitish circle. The antennze 
are dark brown ; those of the male are moderately bipectinated, each 
having about thirty-six rays on each side, a few of the apical joints 
being destitute of rays, and some of the preceding having the second 
ray gradually becoming obsolete. The female antennez are only 
slightly serrated, the second spur on each side of each joint being 
obliterated. The veins are those of the typical Saturnia. 
The female has the body“and wings of a pale reddish buff, with the 
dusky striga beyond the middle almost obliterated, and the dusky 
spot in the middle semicircular. On the underside the hind-wings 
have also a small oval dark spot towards the base.

Isabelle-coloured or pale rufous brown, with an irregular pale 
greyish bar before the middle, followed by an oblique darker fascia, 
on the outside of which is a small semi-oval tale-like spot ; beyond this, 
extending from near the tip of the wings towards the middle of the 
inner margin, is a nearly straight, slender, darker line, edged with 
greyish on each side; the apical margin of the wing beyond the dark 
line becoming grey, shaded off to the ground colour of the wmg. The 
hind-wings have a large ocellus, black in the centre, with a minute 
vitreous dot in the middle, with a red lead-coloured ring outside the 
black, followed by a fleshy-coloured one, and this by a purple-carmine 
one: the outside of the ocellus rests upon a dark, slender, curved line. 
The collar and underside of the body whitish ; head and legs darker 
olive-brown ; antenne black. 
Wings beneath pale reddish buff, of a redder brown near the tip, 
with the dusky subapical line as above, and the vitreous spot pre- 
ceded and followed by a dark claret-brown spot : hind-wings destitute 
of the ocellus, which is replaced’by an indistinct claret-brown spot, 
followed by a red-brown fascia, widest at the anal margin. Near the 
base is also a small brown spot. 
The antennee of the female are serrated, the two terminal rays of 
each joint nearly obliterated, with one-fourth at the apex simple.
