tending to the tip, so that the antennae are composed of about forty- 

 four or forty-six joints. The antennae of the female are setaceous, 

 and only slightly bipectinated, being gradually more slender from 

 about one-third of the distance from the base to the apex, each joint 

 emitting four rays, the joint at each point of emission being swollen. 

 The female has the wings rather shorter, and not at all emarginate 

 along the apical margin.

 The antennae of the male are 39-jointed, with fifty-eight rays on 

 each side (four from each of the twenty-nine or thirty basal joints), 

 the rays lyuig nearly flat. 



The antennae of the female are about 42-jointed, only slightly 

 serrated, each joint having two serratures on each side, the basal one 

 being most prominent, the antennae becoming gradually more slender 

 to the tips. The palpi are short, but distinct and deflexed.

Fore-wings brownish buff, with a pale pinkish white, nearly 

 straight fascia across the wings before the middle, edged towards the 

 base with a fine dark line, the other side shaded off to the ground 

 colour of the wings ; beyond the middle is a small triangidar vitre- 

 ous spot, bounded at the base by the transverse veinlet closing the 

 discoidal cell ; beyond the middle is a straight, slender, dark striga, 

 edged with pale pinkish white ; the outer margin of these wings 

 slightly emarginate ; hind- wings entire, somewhat oval, brownish buff, 

 the middle with a pale rosy tint, bearing an ill-defined whitish fascia 

 towards the base, and another, followed by a dusky line, beyond the 

 middle ; the middle of the wing occupied by an ocellus, with a small 

 glassy centre, surrounded by dirty buff, and this by a black circle and 

 a larger, pale pinkish white one ; thorax in front with a white trans- 

 verse fascia ; antennae dark brown. 



The antermae of the male are small, moderately short, the rays flat, 

 thirty-four rays on each side, one-fourth of the antennae at the tip 

 being destitute of rays. 



The palpi are distinct, but small.
