The fore-wings are of a dark reddish fulvous colour, tinged with 

 red-brown between the middle and the apex. Near the base is a very- 

 irregular, rather indistinct, ashy-purplish striga, and in the middle of 

 the wing is an oval moderate-sized ocellus, the basal half being brown, 

 and the apical half vitreous, the latter surrounded by a slender brown 

 line ; halfway between this ocellus and the apical margin of the v/ing 

 is a straight, slender, brown line, running from near the apex of the 

 wing towards the middle of the inner margin. The hind-wings are 

 of a much redder hue, especially on the anterior portion, with a slight 

 appearance of the sub-basal ashy striga of the fore-wings near the 

 base ; the middle of the wing occupied by a large ocellus, with a 

 vitreous centre, ha\ing a rather broad greyish-black iris surrounded 

 by a white ring, the outer extremity of which rests on a slender dusky 

 striga running from near the outer angle of the wing towards the 

 middle of the anal margin. The body is rich brownish fulvous, with 

 an ashy -brown collar and legs. The antennae black and very slightly 

 pectinated in the female, consisting of about thirty-five joints, the 

 first twenty-five emitting a pair of short slender branches from the 

 base, the tip of the joints being also slightly serrated ; the ten terminal 

 joints are shorter, each emitting a single branch set on in front of each 

 joint, the branches of the preceding joints being set on the upper and 

 lower edges. 



The wings beneath are paler bufP-brown, with a broad, subapical, 

 dusky bar, undulated externally ; the eye of the fore-wings less di- 

 stinct, and that of the hind-wings replaced by two brown spots and a 

 vitreous patch. Near the base of the wings is also a round brown dot.
