AMERICAN LEPIDOPTERA. 15 



From several males taken at Lake Labaclie, British Columbia, by 

 O. R. Crotch, Esq., in 1873. 



This species is of the size of small JVrpheJp, and is plainer colored 

 and with fewer spots. In same vicinity were taken specimens of 

 •S*. Boopis^ Behr. Also of Colias Phihdice. and Art/ynnis^ Aphrodite, 

 neither of which have been known by me hitherto from the Northwest 

 coast. Also one specimen of Vanmsa J (t/l/um, and three females of a 

 Collar, probably Scudderii, Reakirt ; specimens of Arg. CharUlea, or 

 Boisdavallt, considered by some to be a dark var. of Charidea. On 

 Bald Mountain near Lake Labache were taken diminutive specimens 

 of Argi/nnis Bischoffit, Edw., hitherto reported only from KodiaL 

 Near Lake Labache also were taken Arg. Brem»en\ Edw., as well as 

 at Victoria, Vancouver's Island. On this Island a fine specimen of 

 Chionohas Gigast, Butler, was taken, and specimens of Cf)lias Interior^ 

 Scudder. Among the Pleridx, taken by Mr. Crotch, were Pallida., 

 Scudder (Syn. Castoria., Reakirt), and Venom., Scudder, probably 

 syn. with Yreka., Reakirt. Also Okracea; all these from Lake La- 

 bache. 



Argynnis Nitocris, n. sp. 



Male. — Expands 3 inches. Upper side bright fulvous, much ob- 

 scured by brown from base to middle of disk, except upon a portion of 

 cell of primaries; both wings edged by two parallel, fine, black lines, 

 which on secondaries enclose a rather broad fulvous space, on prinia- 

 ries a narrower space, divided by the black nervules; anterior to 

 these lines on primaries a series of black lanceolate spots, the three or 

 four next apex connected and resting upon the inner line, the others 

 separated and not touching the line; on secondaries a series of lunu- 

 lar separated spots; the rounded extra-discal spots as in Nokomis; 

 small on secondaries, rather large on primaries; the markings on disk 

 and to base as in Nokomis, heavy on primaries, light on secondaries, 

 the discal band on the latter broken into small, separate lunules; the 

 spot on the arc like the letter S; fringe of secondaries light fulvous, 

 of primaries deep fulvous, black at tips of nervules. 



Under sider of primaries cinnamon-red from base to hind margin 

 and over entire wing except a small sub-apical space across the sub- 

 costal nervules, which is bright ochraceous-yellow, and a brown patch 

 just anterior to this on costal margin; the black markings repeated; 

 the five lanceolate spots next apex enclosing silver lunules; three 

 silver spots on the brown costal patch, one of them minute.
