tion of subcostal and median nervules. Secondaries wholly pale 

 chocolate brown, with no indication of band. Underside pale 

 brown with a reddish tinge, and with very faint trace of median 

 band on both wings. Thorax and abdomen somewhat paler than 

 the base of the primaries. Antennse, dark chocolate brown. 

 Exp. wings, 0.80 inch. 



? Lighter in color, and less opaque than the $ . Head, 

 thorax, legs and abdomen pale whitish brown ; abdomen palest ; 

 prothorax and tegulae darkest. Anterior wings pale, lustrous 

 whitish brown, crossed by a broad dark band of the same color, 

 but of a deeper shade. The inner edge of this band originates on 

 the inner edge near the base, and curves round to the costa, which 

 is reached at the basal two-fifths. The outer edge of the band is 

 parallel with the outer edge of the wing, and curves outward as it 

 reaches the costa, being followed outwardly by a narrow pale line. 

 The band is palest centrally, and broader than the terminal space, 

 and both its margins are toothed inwardly on the nervules. 



Posterior wings concolorous with the band on the primaries, 

 crossed by a pale median band. 



Beneath, the wings are concolorous with the band on the 

 primaries above, and the only markings are the pale whitish line 

 outside the band on the primaries, and the median line on the 

 secondaries, which are both more prominent than above.

Expanse of tvings, i.io to 1.40 inches. Length of body, 0.40 

 to 0.50 inches. 



Habitat, Virginia City, Nevada (Henry Edwards). 



This species is very strongly marked, and readily distinguish- 

 able from all its congeners by its delicate, fragile appearance, and 

 the thin lustrous squamation of the wings. 



Taken by Mr. Henry Edwards in the early part of July, Mr. 

 Edwards found, during the same visit to the locality mentioned, 

 a single larva belonging to this genus feeding on a large species of 



sunflower {HeliantJms ), which I have little doubt belongs to 



this species. It was smaller than those of C. californica, and more 

 like that of C. constricta, but abundantly distinct from either. It 

 came to my hands through the mail in such a condition as not to 

 admit of a careful description. The only trees growing in the 

 region from which this species was received, are various species 

 of willows or conifers. 



C. CONSTRICTA, n. sp. 



Larva. Head blueish, mottled with black. Body with a 

 moderately broad, irregular, but continuous bright ochreous dor- 

 sal stripe bordered with black. Sides blueish white, faintly mot- 

 tled with black, this color being concentrated into a diffuse lateral 

 stripe just above the lateral bunches of hairs. From the dorsal 

 stripe spring dark tawny hairs, directed upwards, with a few black
