revision of the genus Argynnis. 575 



represents the facts shown by my collection, including 

 about fifty specimens from all the States where the 

 species occurs, and from many of the collections which 

 supplied his own materials. If it should eventually 

 prove that the Pacific coast form is not separable from 

 the Eocky Mountain form montivaga, it may be better to 

 use the name eurynome in preference to montivaga or 

 egleis, because both Behr's and Boisduval's descriptions, 

 which have priority over Edwards's, can only be 

 identified with doubt. My specimens of montivaga and 

 egleis all come from the Sierra Nevada, and not from the 

 Mt. Shasta district, where monticola and its vars. are so 

 abundant ; but local information as to their distribution 

 in this, as in other cases, is very deficient.
