Coelodasys biguttatus n. sp. 



Head gray, vertical tuft above black. Thorax reddish-brown, patagiu 

 blackish above. No distinct line on the prothorax. Primaries reddish 

 brown, nervules black. Base of the costa dark, beyond cinereous with 

 brown scales along the edge, which become indistinct waved lines con- 

 tinued across the wing and are more oblique beyond the discal dot. 

 The linear reddish discal dot is surrounded by gray, and below and 

 beyond is a dark rather broad discoloration curved around it. Beyond 

 this the black nervules are interrupted by gray scales. There are two 

 obscure series of reddish dots near the margin in the interspaces. Op- 

 posite the outer series of these spots the fringe, otherwise ferruginous, 

 is of a dirty white. 



Secondaries white, discolored with smoky at inner angle. The large 

 tuft beneath the head is lilac-ashen. 



Beneath, the fore-wings are white, smoky in the middle. Costo-api- 

 cal dots distinct. Fringe white, black at the ends of the nervules. at 

 the base are white dots in the interspace. Secondaries entirely white, 

 except the dusky spot on the inner angle. 



Legs ashen, ends of the scales dark, tarsi broadly annulated with 

 dark. Abdomen slender, whitish, a narrow mesial line beneath. 



In the female the markings are more distinct. The two series of 

 ferruo-inous waved lines on each side of the median region are more 

 distinct. The submarginal ferruginous region is more broken up by 

 ashen scales. The secondaries and abdomen above smoky. There are 

 faint traces of a slight mesial fascia across the wing. Beneath botli 

 wings are dark smoky. A light ferruginous line on the abdomen, 

 which is itself larger than in the other species. 



Length of body, S .90, 9 .95; exp. wings % 1.60, $ 1.80 inch.
