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. n, $, 

 underside; 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, $ ; 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. 



(9) Argynnis alcestis, Edwards, Plate X, Fig. 6, 6 , under 

 side (The Ruddy Silver-spot). 



Butterfly. — Very much like aphrodite, from which it may be
