304 AMERICAN LEPIDOPTERA. 



found two specimens with spots on the secondaries. The series of 

 specimens is as follows : 



Primaries. Secondaries.

30 "0 



The species varies in color above to a slight degree, some speci- 

 mens showing a different shade of light buff. There in considerable 

 difference on the underside. Some specimens almost fuscous; some 

 are immaculate on the under side of both wings. The species flics 

 in Vane, Wash., Oreg., Nev., Mont., Utah, Idaho. 



I have fresh specimens taken in May, June and September. 



C. elko Edw., Can. Ent. 13. 57, 1881. 



"Male: — Expands .95 to 1 inch. Upper side pale ochre-yellow, immaculate; 

 fringes concolored. Upper side of primaries nearly same ochre-yellow over basal 

 area and part of disk, limited without by a slightly sinuous and crenated edge of 

 deeper color, much as in the allied species; outside this, slightly ochraceous next 

 inner angle, hut yellow-huff over apical area. Secondaries have the basal area 

 uniform grey-brown, the outline distinct and in strong contrast with the re- 

 mainder of the wing, which is yellow-buff*. Very slightly grey; the outline is 

 irregularly crenated, with a deep sinus on upper subcostal interspace, and 

 another on low T er disco-cellular interspace. 



" Female: — Expands 1 inch to 1.02. Upper side like the male. Beneath, the 

 area just outside the the crenated edging on disk of primaries is yellow for a 

 little distance, then tinted ochraceous to margin, in one example a minute black 

 dot in the disco-cellular interspace with white centre, in another no dot; second- 

 aries as in the male, basal area one shade of grey, witli distinct crenated outline, 

 and beyond a yellow or buff-ground to margin, very little dusted grey." 



" From two $ $ and two 9 9 taken at Elko, Nevada, 1881, and 

 sent to me by Mr. J. Elwyn Bates, of South Abington, Mass. Mr. 

 Bates informed me that he had quite a number of examples. The 

 present species is nearly the same color with C. ampelos Edw., from 

 Oregon ; on upper side a little more yellow, and with less gloss. 

 The under side is much lighter, and on secondaries the contrast be- 

 tween the dark basal area, with its clear cut outline and the pale 

 yellow extra discal area, is great. Ampelos has the under side of 

 same general character as inornata Edw. (only different in coloring), 

 from Montana and Winnipeg. Elko resembles californica Bois., 

 rather, in which species, many examples have the basal area dark 

 and the entire outline of same distinctly defined." 



These spots are not exactly ocelli, but pin-point black dots sur- 

 rounded by a yellow ring.
