 brown outer marginal band, and costal area somewhat broadly brown.

Described iram five males and eight females. One male from the 

 foothills, " Lineham'p lower log camp, south fork of Sheep Creek," about 

 thirty-five miles south-west of Calgary. Ail the rest from near the spruce 

 woods about ten or fifteen miles nearer Calgary, July 5th-2oth, all but 

 three of the males quite fresh, though one broken in the mail. Types, ^ 

 and 9 i'l U. S. National Museum, the rest co-types. Of these a pair are 

 in the collection of the Entomological Society of Ontario, another 

 pair in th;it of Dr. Henry Skinner, and the rest in that of the author. 

 Dr. Fletcher and Dr. Holland each have a few specimens. I know of no 

 others. 



This may be looked upon as the Rocky Mountain representative of 

 hypopklceas, from which it shows some striking differences, particularly in 

 the male sex. It is larger, has more acute apices, and straighter outer 

 margin. The shining bronze of the dark smoky suffusion, which generally 

 obliterates the margii al band, renders some of the males far more hand- 

 some than any of the long series of its allies that I have from this 

 continent, Europe or Asia. Beneath it differs in the strong tendency 

 towards obsolescence of the spots and orange submarginal line on 

 secondaries. In the absence of any widely-accepted definition of what a 

 " species " really is, from its well-marked form and apparently isolated 

 position on the entomologically-explored portion of North America, it is 

 at least as deserving of a specific name as a large number of well-known 

 forms on our lists. It has, however, some much nearer allies in some of 

 the so-called forms of phlceas that I have from the Himalayas and from 

 Syria under the names of eietts and stygianus, which, according to the 

 Staudinger Catalogue, refer to the same form, and occur throughout the 

 south palearctic region. And were I treating of the butterflies of the 

 world, in which a tendency to lump would be scarcely avoidable, I should 

 have left the Calgary form undescribed, and probably followed European 

 authors in treating our common eastern species as a varietal form oi phlceas.
