brown, and a distinct whitish band across the wing; otherwise like 

 male. 



From several specimens taken in Colorado by Mr. Mead. 



This species may be readily distinguished from Camillas by the 

 absence of the black patches so conspicuous in that species, as well as 

 by several characteristics noted in these descriptions. 

 Chrysophanus Sirius, n, sp. 



Male. — Expands 1.3 inch. 



Upper side brilliant copper-red, deepest on costal margin of primar- 

 ies and both hind margins and on all the nervures, the interspaces hav- 

 ing a brown shade when viewed directly, but fiery red otherwise ; on 

 the hind margin of secondaries the metallic border is broken into spots 

 towards anal angle, these spots enclosing black lunules that are pro- 

 duced by the expansion of the black line that edges both margins 

 discal spot of primaries a straight fuscous bar; a fuscous point in cell 

 discal spot of secondaries a streak, and three or four points on disk 

 fringes grey-white. 



Under side of primaries pale buff", of secondaries still paler; prima- 

 ries have a submargiual row of rounded fuscous spots only distinct nest 

 inner angle ; a bent row across the disk, rounded, nearly equal, a bar 

 on arc, a spot and a point in cell and a spot below in median inter-

 ner angle; secondaries have a marginal band of black spots over which 

 are fulvous serrations; all the spots of under »ide appear on upper. 



Taken in Colorado by Mr. Mead. 



The female in scarcely distinguishable from that of Lj/c. Heteronea.

Male. — Expands 1.1 inch. 



Upper side fuscous with a slaty-blue reflection at base and on disks ;
