 Rocky Mountains, from Colorado northward. 



The description of Arnica Edic. is insufficient to refer it positively to this 

 species ; but it will probably be found to be the same. It may perhaps be 

 long to Aquilo.

 Food-plant; Lxipinns. 



Minnehaha was improperly compared by me with Reakirt's Maricopa, to 

 which it is not closely allied. It differs slightly from specimens I have seen 

 of Boisduval's lupini, but it is probably not distinct.

The only difficulty in referring to Shasta the species of Felder, Behr and 

 Boisduval (which are undoubtedly the same) is that Edwards describes his 

 female as " clear brown" above, with no reference to any basal suffusion with 

 blue.
