This Colias is quite distinct from any known American species, ex- 

 cepting Hecla^ to which it is allied. 

 Argynnis Helena, n. sp. 



Male. — Expands 1.6 inch. 



Upper side bright fulvous, but little obscured at base ; marked 

 more nearly like Chariclea, than any other of our species. Under side 

 of primaries pale cinnamon or brown, except apically where the color is 

 ochraceous, with a deep ferruginous patch on costa curving around to 

 hind margin, interrupted partially in the lower sub-costal interspace; 

 the spots on the disk of upper side faintly repeated, the black 

 rounded spots nearly wanting, represented only by two or three dots on 

 the disk ; the marginal lunules obsolete. 



Secondaries deep ferruginous from base to middle of wing, enclos- 

 ing a transverse band formed of yellow spots separated by the ferru- 

 ginous nervures; in the basal space a yellow patch at origin of sub- 

 median and of sub-costal nervures and a round spot much covered 

 with black scales in the cell; shoulder yellow; outside the ferruginous 

 space a narrow band of whitish lunules interrupted in middle of disk ; 

 beyond to hind margin the space is brown ferruginous at the extrem- 

 ities, ochraceous in the discoidal and partly so in the upper sub- 

 costal interspaces; a row of ferruginous points crosses the limb; mar- 

 gin edged by a series of elongated white spots forming an interrup- 

 ted band, on the anterior side of which, at the extremes, are ferrugi- 

 nous lunules. 



Body above fuscous with fulvous hairs, beneath grey fulvous; palpi 

 fulvous; antennae annulated fuscous and ochraceous, club black, ful- 

 vous at tip. 



Female. — Same size and similar. 



Taken by Mr. Mead in Colorado. In addition to the present spe- 

 cies, Mr. Mead, also found Arg. Frei/a, Chariclea and Eplthore, the 

 two former of which were not before known as belonging to the 

 United States. 



Phyciodes Camillus, n. sp. 



Male. — Expands 1.3 inch. 



Upper side black, spotted with fulvous ; both wings have an imper- 

 fect submarginal series of fulvous crescents, the middle one on primar- 

 ies much the largest, and usually the only one distinctly visible ; a 

 second row of small fulvous spots, enlarged on secondaries and there 

 enclosing black points ; a discal row, paler, large, sub-quadrate, tor- 

 tuous on primaries, nearly parallel with hind margin on secondaries;
