EDWARDS ON LEPIDOPTERA OF MONTANA. 515 



7. Argynnis nevadensis, Edwards. 



This butterfly was taken near Three Buttes, August 8. It is allied to 

 edwardsi in shape, and forms a subgroup with it. It is brighter-colored, 

 smaller-sized, and beneath the ground-color is yellow or buff, mottled in 

 the male with pale olive-green, and in the female with darker buff. The 

 species ranges from Nevada northward, and is confined to the mountains. 



8. Argynnis clio, Edw., (new species). 



A female was taken at Chief Mountain, August 21. The male was 

 known to me from a specimen formerly taken by Dr. Hayden's Montana 

 Expedition. Both sexes expand two inches, and resemble eurynome, Edw., 

 in size and shape. The black markings of upper side are less sharply 

 defined, nearly all of them having a rough edging. On the under side, 

 the spots which in most species of Argynnis are silver are here buff, 

 with no trace of silver. 



9. Argynnis rhodope, Edwards. 



A single female was taken, August 8, near Three Buttes, and is the 

 first instance which has come to my knowledge of the appearance of 

 this species within the United States. The only examples hitherto taken 

 have come from Cariboo, British Columbia. 



' The Argynnides comprise a very large proportion of the species of 

 butterflies of the United States and British America, more than forty 

 having been described. Of these, the larger part inhabit the Eocky 

 Mountains and the districts beyond to the Pacific. They are mostly local 

 in their habits, and are confined to the valleys and lower slopes of the 

 mountains, alighting on flowers. The larvae so far as known feed upon 

 different species of violet, and the larger species are single-brooded, 

 hibernating in the larval state. 



10. Phyciodes marcia, Edwards. 



A single specimen, collected at Milk Eiver, July 25. This species is 

 allied to Tharos, and may yet be found dimorphic with it. The two 

 range over the whole of the region east of the Kocky Mountains, and have 

 been taken also in Colorado. To the westward they are replaced by 

 campestris, mylUtta, and other allied species, though to the northwest 

 Tharos has been taken quite at the Pacific — in British Columbia. It is 

 also found on the Mackenzie Eiver. These small butterflies are com- 

 mon on the Plains, and in cultivated districts frequent meadows.

11. Vanessa antiopa, Linnseus. 



12. Pyrameis cardui, Linnajus. 



These two species inhabit the entire continent, and the Old World 

 as well, the boreal regions excepted. I have received antiopa from the
