Genus Argynnis 
side the wings are pale greenish-yellow, with the fore wings 
laved with bright pink at the base and on the inner margin. 
The spots of the upper side reappear on the under side as spots 
of silver bordered narrowly with black. The female has the 
ground-color of the upper side yellow, shaded outwardly with 
fulvous. All the dark markings of the male sex reappear in this 
sex, but are much broader, and tend to fuse and run into one 
another, so as to leave the yellow ground-color as small subquad¬ 
rate or circular spots, and wholly to obliterate them at the base 
of the wings. On the under side this sex is marked like the male, 
but with all the markings broader. Expanse, 3.40-3.60 inches. 
This species, the male of which resembles the male of A. leto, 
and the female the same sex of A. diana, is as yet quite rare in 
collections. It has been taken in Arizona and southern Utah. 
We have no knowledge of the life-history of the species.

Butterfly. —The male is bright reddish-fulvous, marked like A. 
nokomis. The under side of the fore wings is cinnamon-red, 
ochre-yellow at the tip. The hind wings are deep rusty-red, 
with a broad yellowish-red submarginal belt. The silver spots 
are as in A. nokomis. The female on the upper side is blackish- 
brown, darker than A. nokomis. The extradiscal spots in the 
transverse rows are pale yellow, and the submarginal spots 
whitish. The under side of the fore wings is bright red, with 
the tip yellow. The hind wings on this side are dark brown, with 
a submarginal yellow belt. Expanse, 3.25-3.75 inches. 
This species, like the preceding, is from Arizona, and nothing 
is known of its egg, caterpillar, or chrysalis.

Butterfly.— The male on the upper side is marked much as A. 
nokomis , but the ground-color is duller red, and the basal area is 
much darker. The under side of the fore wings is pale fulvous, 
upon which the markings of the upper side reappear; but there are 
no marginal silver crescents. Both wings on the under side are 
shaded with brown toward the base; the hind wings are trav¬ 
ersed by a submarginal band of light straw-yellow. The female 
is marked as the male, but the ground-color is pale straw-yellow, 
and all the darker markings are deep blackish-brown, those
