Genus Argynnis 
Early Stages .— Not yet ascertained. 
The type specimens upon which the foregoing description is 
founded came from Mendocino, in California. 
(24) Argynnis halcyone, Edwards, Plate XIII, Fig. 5, & ; 
Fig. 6, $ , under side (Halcyone). 
Butterfly , $.— The primaries are produced and relatively 
narrower than in the preceding species, fulvous on the upper 
side, with the black markings distinct, the mesial band of the 
secondaries confluent. The fore wings on the under side are 
pale fulvous, reddish at the base, pale buff at the end of the cell 
and on the costal margin before the apex. The subapical spots 
and the pale spots of the marginal series are very little silvered. 
The hind wings have the inner two thirds deep reddish-brown, 
slightly mottled with buff. The marginal band is buff, and all 
the spots are well silvered. 
$.—The female, which is considerably larger than the male, 
is marked much as in that sex; but all the black markings are 
heavier, and on the under side of the primaries the base and inner 
margin are laved with red. The marginal band on the hind 
wings is not as distinct in this sex as in the male, in many speci¬ 
mens being somewhat obscured by olive-brown. Expanse, $ 9 
2.50 inches; ? , 2.90-3.10 inches. 
Early Stages .— Not known. 
This species, which is still rare in collections, is found in 
southern Colorado and the adjacent parts of Utah and Arizona. 
(25) Argynnis chitone, Edwards, Plate XIV, Fig. 16, ? 
(Chitone). 
Butterfly , 6.—The wings on the upper side are dull fulvous, 
greatly obscured by brown at the base of the wings. The dark 
spots and markings are not heavy. The fore wings on the under 
side are yellowish-fulvous at the base and on the inner half of 
the wing; the apical patch and the nervules on the apical area 
are heavy ferruginous; the marginal spots are buff, with no 
silver. The hind wings on the under side are light ferruginous, 
mottled with buff; the belt is broad, clear buff; the outer margin 
is brown. All the spots are small and imperfectly silvered. 
$.—The female is nearly the same shade as the male, with 
the marginal spots on the under side always silvered, the re¬ 
mainder without silver, or only now and then with a few silvery 
scales. Expanse, 2.25-2.50 inches.
