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 

 a small, round, dusky spot, having an indistinct vitreous lunule in the 

 middle, and surrounded by an indistinct whitish circle. The antennae 

 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 antennae are only 

 slightly serrated, the second spur on each side of each joint being 

 obliterated. The veins are those of the typical SaturnicB. 



The female has the body and wings of a pale reddish buif, 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 talc-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 wing. 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 ; antennae 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-browTi 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.
