Genus Argynnis 
a colony, as CEneis semidea is isolated upon the summit of Mount 
Washington. Specimens of cybele much like those of this New 
Mexican variety are found in eastern Maine and Nova Scotia, and 
on the high mountains of North Carolina. 
(7) Argynnis aphrodite, Fabricius, Plate XIV, Fig. 11, $, 
under side; Plate V, Fig. 5, chrysalis (Aphrodite). 
Butterfly. —This species closely resembles cybele, but is gen¬ 
erally smaller, and the yellow submarginal band on the hind 
wings is narrower than in cybele, and often wholly wanting, the 
hind wings being broadly brown, particularly in the female sex. 
The under side of the fore wings at the base and on the inner 
margin is also brighter red. 
The caterpillar, chrysalis, and egg of this species closely re¬ 
semble those of cybele . The caterpillar has, however, a velvety- 
black spot at the base of each spine, the chrysalis has the 
tubercles on the back shorter than in cybele, and the basal seg¬ 
ments are party-colored, and not uniformly colored as in cybele. 
(8) Argynnis cipris, Edwards, Plate XII, Fig. 3, <3 ; Fig. 4, 
$ (The New Mexican Silver-spot). 
Butterfly. — This species, which belongs to the Aphrodite- 
group, may be distinguished by the fact that the fore wings are 
relatively longer and narrower than in aphrodite. The black 
markings on the upper side of the wings in both sexes are nar¬ 
rower, the dusky clouding at the base of the wings is less pro¬ 
nounced, and the ground-color is brighter reddish-fulvous than 
in aphrodite. On the under side the fore wings lack in the 
male the pinkish shade at the base and on the inner margin 
which appears in aphrodite, and both the male and the female 
have the inner two thirds of the hind wings deep cinnamon-red, 
with only a very narrow buff submarginal band, deeply invaded 
on the side of the base by rays of the deeper brown color of the 
inner portion of the wing. Expanse, 2.75-3.15 inches. The 
insect flies from late June to the end of August. 
Caterpillar, etc. — We know nothing of the larval stages of 
this insect. The specimens contained in the Edwards collection 
came from Colorado, Utah, and New Mexico, and these localities 
approximately represent the range of the species.
