3 t?. — Body and wings uniformly pearly-ash. Front dark chocolate- 

 brown. Fore wings with two dark lines, which arise wide apart on the costa, 

 curve outward, and unite just behind the third median vein, and then form a

 a dark, triangular inclosure, limited by a distinct brown line, the apex obtuse 

 and directed toward the base of the wing. Fringe slightly checkered with 

 brown, otherwise concolorous with the wing. Both wings with scattered 

 brown striga\ Hind wings with two subparallel dark lines, the inner quite 

 regularly curved, the outer with a large, sharp angle in the middle of the 

 wing. A few marginal dark dots on the outer edge near the last point. 

 Beneath, dull pearl-brown ash, with no markings, but a few fine, scattered, 

 dark strigse. Legs a little more dusky than the wings.

This beautiful and singular species may be recognized by ils three- 

 toothed hind wings, the anterior pair being entire, by its delicate pearl-ash 

 tint, and the meeting and separating of the two lines forming a large triangle 

 on the inner edge of the hind wings: also by the large acute angle made by 

 the outer line on the hind wings.
