are known to me. The prevalent color of the fore wing is black; at the base there are 

 some bluish fuscous scales of the same color as the vestiture of the thorax and ab- 

 doinen on the upper side, these bluish scales being most noticeable where they over- 

 lay the inner area of the subbasal white triangular spot, which extends from near the 

 middle of the cell to the inner margin to a little before the middle of the wing; there is a 

 diagonal moderately broad white subapical band, which does not reach either the 

 costa or the outer margin. The hind wing on the upper side is white, bordered from a 

 little before the middle of the costa with black which sweeps around the wing to the 

 base, but on the inner margin is heavily clothed with bluish fuscous hairs. On the 

 imder side the wings are much as on the upper side, but there is a small orange spot 

 at the very base of the hind wing. Expanse, 37 mm. 



The type, which is unique, was taken at Medje in the early part 

 of August 1910 and is deposited in The American Museum of Natural 

 History.

 d^. Antennae pectinate; tibia of hind legs not dilated, having two pairs of spurs; 

 fore wing truncate at apex; hind wings truncate and straight from anal angle to 

 extremity of vein 4, twice denticulate between vein 4 and the upper angle; frons 

 white ; vertex ochraceous ; upper side of thorax and abdomen very pale gray ; under 

 side of thorax and abdomen whitish; legs concolorous; fore wing on the upper side 

 prevalently pale gray tinged with pink, irrorated with pale brown stria;; an anti- 

 median greenish band marked at the costa with a brown spot, runs from the costa to 

 the hind margin; this is succeeded by a postmedian irregular band made up of small 

 sagittate points, their apices pointing basad, the spot on the costa most conspicuous. 

 This band is folloAved by a pale greenish shade, most noticeable in the subapical 

 region. There is an irregular submarginal band, composed of brown sagittate spots, 

 beyond which, between veins 4 and 5, is a whitish patch, and behind which, near the 

 inner angle, there is a similar whitish lunular patch accentuated externally by dark 

 brown. There are traces near the lower angle of a fine dark marginal line. The fringes 

 are dark brown, checkered with lighter between the apex and vein 4. The hind wing 

 on the upper side is marked like the fore wing, the transverse bands of the fore wing 

 being continued across it, but narrower and less distinct. There is a minute black 

 point at the end of the cell. The hind margin of the wing, from the anal angle to the
