and believe them to be all one species. As compared with the 

 plate of Nevadensis $ , in Vol. III. of Mr. Edwards's Butt. N. Am., 

 all the $ $ I have seen are larger and darker above. The silver 

 spots are generally more elongated, and the reddish area on 

 primaries beneath generally brighter, especially near the base, but 

 in some specimens almost lacking, or confined to the mere 

 bordering of the veins. In a few £ $ this reddish tinge is absent. 

 The shade and intensity of the green is extremely variable. One 

 of my specimens is labeled "Nevadensis 9 " by Mr. Edwards him- 

 self. The specimen has lost its abdomen, but I believe it to be a 

 £ . I have compared specimens from Lacombe, called Edwardsii 

 by Dr. Fletcher, with the south of Calgary form, and can see no 

 difference. Dr. Skinner has seen the species, and says : " The 

 specimens you send are certainly not Edwardsii, nor are they true 

 Nevadensis ; nor are they exactly like the Colorado Meadii, but 

 they come nearest to Meadii." It is worthy of note that the great 

 majority of my specimens of this species are ? $ • In every 

 other species of Argynnis occurring here, the proportion of $ $ 

 taken will exceed the $ $ by at least five to one. 



io. A. eurynome, Edw. Very common everywhere. July and August. 

 Var. clio, Edw. Not rare, and widely distributed south of Calgary. 

 Banff (Sanson). Mr. Gregson says it is extremely local at Lacombe. 

 I have a specimen, which Mr. Edwards called an " unsilvered " 

 Nevadensis, which I believe to be 9- clio, and Mr. Elwes supports 

 me in this view. 



ii. A. myrina, Cram. Locally common. Calgary and Lacombe, July 

 and August. Banff, June 17th (Sanson). 



12. A. triclaris, Hub. Not rape locally, on marshy ground near the 



spruce timber ; July. Banff, June 3rd (Sanson) ; Laggan (Bean) ; 

 Lacombe, very local (Gregson). 



13. A. chariclea, Schneid. Very common in the mountains and as far as 



the eastern limit of the spruce. I believe the form is referable to 

 Boisduvalii. Mr. Elwes has taken it himself at Laggan. and 

 considers Boisduvalii and chariclea to be synonymous. 



14. A. freija, Thunb. Common everywhere in the hills near Calgary, 



preferring hillsides amongst dwarf willow bushes ; May (earliest
