before the lower end of cell, 2 from near the base ; sub-median nervure straight, 

 internal nervure short. Costa arched before its middle, then gently curved to the 

 apex, which is somewhat rounded, outer margin slightly convex ; hinder angle rounded, 

 but well pronounced, hinder margin straight. Hindwing, vein 8 evenly curved, 

 7 emitted about one-sixth before upper end of cell, upper discocellular short, strongly 

 concave, outwardly oblique, the lower three times as long as the upper, in the same 

 line, slightly concave, vein 5 well developed, from the junction of the two disco- 

 cellulars, 3 from a very little before lower end of cell, 2 from about one-fourth before 

 the end ; sub-median and internal veins sinuous, wing somewhat elongated, longer 

 than broad. Costa arched, apex rounded, outer margin straight from the apex to the 

 end of vein 4, then well rounded hindwards ; anal angle dilated, folded over beneath 

 the cilia, being there developed into two or three strong and thick tufts of hair, 

 abdominal margin nearly straight. Antennae half the length of the costa, with a 

 well-formed, curved club ; palpi with the third joint minute, pointed, first and second 

 densely pilose, thorax rather robust ; hind legs with a dense bunch of hairs from the 

 base of the tibia and lying along that joint ; abdomen short, robust. The female 

 broader than the male, otherwise similar.

Imago. — Male. Upperside dark blackish-brown. Forewing with five sub-apical 

 ochreous-white dots in an outwardly curved series, a silvery lustrous band from near 

 the middle of the costa to near the hinder angle, commencing in almost a point 

 above the sub-costal vein rapidly broadening and then gradually narrowing hind- 

 wards, its margins irregular, with a detached dot below its lower end. Hindwing 

 without markings. Underside with the ground colour a little paler and duller, the 

 spots and bands as above ; but the band is white, not lustrous ; palpi dark ochreous, 

 with blackish-brown sides, and a white patch beneath below each eye ; head and body 

 above and below and the legs concolorous with the wings. 



Female, like the male on both sides, but in the forewing the band is broader 

 and extends a little further anteriorly and posteriorly, and the sub-apical spots are 

 somewhat larger, and the hindwing has a discal series of five rather elongated spots, a 

 little darker than the ground colour, one in each interspace from vein 8 to vein 2. 



Expanse of wings, ^ $ 2^ to 2^ inches.
