taken in California Gulch, which showed no trace of the usual silvering on

ARGYNNIS MYRINA, Cramer. 



Argynnis Myrina, Harris, Insects Injurious to Vegetation.

 Argynnis Bellona, Harris, Insects Injurious to Vegetation. 



A single specimen, fresh from chrysalis, was taken near the Hot Springs, 

 Middle Park, August 14. 



The larva of Bellona resembles more closely that of Cybcle than that of 

 Myrina, thus affording additional evidence of the artificial character of the 

 genus BrentMs erected to contain these smaller Argynnides. 



ARGYNNIS EP1THORE, Boisd. 



Argynnis Epithorc, Edw., Proc. Eut. Soc. Pbila., 1804. 



Specimens from Colorado differ from Pacific coast individuals in having 

 the dark markings of the upper side coalescent toward the base ; below, the 

 secondaries are darker purple, and show slight differences in the arrange- 

 ment of the median band of spots. In Colorado, the species frequents the 

 same localities as A. Freya, and has similar habits, but appears from one to 

 two weeks later in the season, disappearing about the last of June. Both 

 were found on Beaver Creek, near Fairplay, and near the Kenosha House, 

 four miles from the South Park ; elevation, 0,000 feet, 



ARGYNNIS FREYA, Tbunberg. 



Argynnis Freya, Godart, Eucyc. Metb. IX.,

 first to appear of the small species of Argynnis. In May, or early in June, 

 it may be found in some numbers near the Smith Park.
