as the outer margin ; costal nervure ending on tbe margin a little 

 before the apex of the discoidal cell ; subcostal nervules arising at 

 decreasing distances apart ; discoidal cell narrow, less than two-thirds 

 the length of the costa ; upper disco-cellular nervule stout, straight, 

 short, strongly outwardly oblique ; middle disco-cellular thin, long, 

 nearly twice as long as the lower disco-cellular, strongly inwardly 

 oblique, at first straight, the posterior portion curved outwardly ; 

 lower disco-cellular short, straight, in the same straight line as the 

 middle disco-cellular ; second median nervule arising far before the 

 lower end of the cell ; first median arising nearer to the lower 

 end of the cell than to the base of the wing, rising in fact about 

 twice as far from the second median as that vein does from the 

 third ; subrnedian nervure bowed, the curvature beiag in the 

 direction of the costa ; a long and thick tuft of hairs (in the type 

 species only) attached to the wing-membrane on the underside towards 

 the base of the wing between the subrnedian nervure and the inner 

 margin, the tuft turned forwards. Hindwing, much longer than 

 broad ; costa strongly arched at base, thence straight to apex ; apex 

 well rounded ; outer margin convex on the whole, but between the 

 second median nervule and the subrnedian nervure it is emarginate ; 

 anal angle well rounded ; abdominal margin convex ; costal nervure end- 

 ing at the apex of the wing, well curved throughout its length ; first 

 subcostal nervule arising well before the apex of the cell ; discoidal cell 

 short, not reaching to the middle of the wing, broad ; disco-cellular 

 nervules thin, nearly straight, outwardly oblique ; discoidal nervule 

 wanting ; second median nervule arising well before the lower end 

 of the cell ; first median arising about as far (perhaps a little 

 farther) from the second as the second does from the third, all three 

 median nervules crowded together near the lower end of the cell ; 

 subrnedian and internal nervures straight. Female differs from the 

 male in lacking the tuft of hairs on the forewing, the hindwing is 

 rather broader, and the disco-cellular nervules are strongly concave 

 instead of nearly straight. Antenna almost exactly half the length of 

 the costa of the forewing, with a long well-formed club ending in a 

 short whip-like terminal crook. Palpi broad, second joint densely 

 hairy, third joint very short. Thokax robust. Abdomen not quite 

 reaching to the anal angle of the hindwing when the butterfly is at rest
