Genus Argynnis 
and some authors are inclined to regard it as being a mere vari¬ 
ety, which is a belief that can only be verified by careful breed¬ 
ing from the egg. 
(22) Argynnis rhodope, Edwards, Plate XI, Fig. 6 , $, under 
side (Rhodope). 
Butterfly .-— In the male sex the upper side is bright fulvous, 
with both wings on the inner half heavily clouded with dark fus¬ 
cous. The black markings are very heavy and confluent. The outer 
border is solid black, very slightly, if at all, interrupted by a nar¬ 
row marginal brown line, in this respect resembling A. atlantis . 
On the under side the fore wings are dark ferruginous, on the 
outer margin rich dark brown. Between the spots at the end 
of the cell and the nervules below the apex are some clear, bright 
straw-yellow spots. The upper spots of the marginal series are 
silvered. The hind wings are dark reddish-brown, very slightly 
paler on the line of the marginal band. The spots are pale straw- 
yellow, except those of the marginal series, which are distinctly 
silvered. The female on the upper side is of a lighter and 
brighter red, with the markings dark and heavy as in the male 
seXo On the under side the markings in the female do not differ 
from those in the male, except that the primaries on the inner 
half and at the base are bright pinkish-red. Expanse, £, 2.20 
inches; $, 2.40 inches. 
Early Stages .— Unknown. 
This striking species has been heretofore only found in British 
Columbia. 
(23) Argynnis behrensi, Edwards, Plate XIV, Fig. 10, S, 
under side (Behrens’ Fritillary). 
Butterfly .— The male on the upper side is dull fulvous, 
clouded with fuscous at the base, the black markings much nar¬ 
rower and lighter than in the preceding species. The primaries 
on the under side are pale fulvous, clouded with dark brown at 
the apex. The subapical spots and the upper spots of the mar¬ 
ginal series on this wing are well silvered. The hind wings on 
the under side are deep reddish-brown, with the marginal band 
only faintly indicated. All the spots are distinctly well silvered. 
The female does not differ materially from the male, except in the 
larger size and the somewhat paler ground-color of the upper side 
of the wings. On the under side the wings are exactly as in the 
male, with the marginal band even less distinct than in that sex.
