Il8 FIFLD AND FOREST. 



Body above concolored, beneath brown, with gray hairs on thorax, 

 the abdomen gray ; legs brown ; collar broadly orange, and palpi 

 orange ; antennae black, the under side imperfectly annulated with 

 gray-white ; club black, on under side more or less whitish. 



From a single example taken by Mr. Morrison in Southern Colo- 

 rado, and the only one met with. The species is at once distin- 

 guished, by the orange collar and palpi, from any other at present 

 known to our fauna. The species belongs to sub-group of Osyka. 



Amblyscirtes Aenus. 



Male. — Expands i.i inch. 



Upper side brown, with a yellowish tint; primaries have a series of 

 small yellow spots, beginning on costa near apex and passing round 

 the end of the stigma and thence back of same to inner margin ; the 

 three next costa nearly perpendicular to it and bright ; the rest less 

 decided in color and less distinct in outline ; the stigma is represented 

 by a slight thickening and blackening of the median nervure, fringes 

 cinereous and brown, alternately. 



Under side of primaries brown, towards apex darker and dusted 

 with gray scales, at base yellowish. 



Secondaries umber dusted with gray ; across the disk is an indis- 

 tinct band of small gray spots, or clusters of scales, and two or three 

 others towards base. Another example has the three costal spots on 

 both sides distinct, but the rest are nearly obsolete. 



Body above brown; below, thorax gray, abdomen-gray brown ; legs 

 gray and brown ; palpi white at base, with many black and brown 

 hairs above ; antennae black with white rings ; club black, whitish 

 beneath. 



Female. — Same size. Both sides lighter colored, the marking sim- 

 ilar to male. The position of this species is between Eos and Textor. 



From two examples taken by Mr. Morrison in Southern Colorado. 



Amblyscirtes Nilus. 



Male. — Expands i.i inch. 



Upper side light brown, glossy ; primaries have three small, equal, 

 pure white spots in line from costa, near apex, and a still smaller one 

 in upper median interspace ; secondaries immaculate ; fringes of pri- 

 maries alternate brown and white, of secondaries white, cut with 

 brown at the end of the nervules on middle of the wing only. Under
