Genus Argynnis 
secondaries being heavily obscured by blackish, so as to conceal 
the markings. Both wings have moderately heavy black mar¬ 
ginal borders. The other markings are as in A. eurynome . On 
the under side the fore wings are buff, laved with reddish at the 
base. The hind wings are pale buff, with the basal and discal 
areas mottled with green. The marginal belt is clear buff. In 
some specimens the spots on the under side are not silvered; in 
others they are well silvered. 
$.—The female on the upper side is very pale buff, slightly 
laved with fulvous on the outer margin of both wings. All the 
markings are heavy; the margins of both wings are solid black, 
the spots within the lunules being pale and almost white. The 
fore wings at the base and the inner half of the hind wings are 
almost solid black. On the under side the wings are very much 
as in the male, and the same variation as to the silvering of the 
spots is found. Expanse, £, i.Soinch; $, 1.90 inch. 
Early Stages .-—Unknown. 
The types of this genus came from Sitka, in Alaska. It may 
be an extreme boreal variation of A. eurynome .

Butterfly , £ .-—The wings on the upper side are bright 
yellowish-fulvous, but little obscured at the base. The outer 
margins are edged by two fine lines which are occasionally con¬ 
fluent. The under side of the fore wings is pale buff, laved with 
cinnamon-brown at the base and along the nervules; the spots 
on the margin and in the apical area are well silvered. The 
hind wings on the under side are buff, with the basal and discal 
areas mottled with pale brown or pale olive-green. The marginal 
belt is broad and clear buff; all the spots are well silvered. 
$ .-—The female is like the male, but paler, with the dark 
markings, especially those of the margin, heavier. The marginal 
spots inclosed by the lunules are much paler than the ground- 
color, and in many specimens almost white. On the under side 
the wings in this sex are like those of the male, but the fore 
wings are more heavily laved with cinnamon-brown at the base. 
Expanse, £, 1.70-2.00 inches; $, 2.00 inches. 
Early Stages— Mr. Edwards, in “The Butterflies of North 
America,” vol. ii, has given us a beautiful figure of the egg of 
this species. Of the other stages we have no knowledge.
