upper wings were absent. Many had none on lower wings, others showed 

 black points more or less minute. 



"• This variety, which Mr. Elwes has called E. Brucei I see, is prob- 

 ably peculiar to these high stations, where I have found it during three 

 seasons, for, in the valley below, there was a narrow, boggy tract, more 

 than a mile long, where Epipsodea was plentiful ; but I found none of the 

 variety spoken of The only variation there was marked by the absence 

 of the band on under side hind wings, and this was confined to few indi- 

 viduals. 



" Epipsodea has a rather quick, jerky flight. It is not very readily 

 captured, for, although it never appears to be in a great hurry, it flies close 

 to the ground, and is always just ahead, dodging under every bush, and 

 around every grassy hummock, as if in earnest search for something. It 

 takes long flights without going far away, and seldom alights on flowers. 

 Directly the sun is obscued, it dives in the grass, like almost all the 

 mountain diurnals. All the Erebias, as well as the alpine species of 

 Chionobas, ' play possum,' and pretend to be lifeless when captured, and 

 will lie in or under the net, or on one's hand, some moments in that con- 

 dition. I have found Epipsodea from June 9th to the end of August, in 

 the front Range, in Colorado ; at the latter date it was badly worn." 



Mr. Elwes says, Tr Ent. Soc, Lond., 1889, Part II, p. 334: " I have 

 a single specimen, and Mr. Godman has a similar one, collected by 

 Bruce in Cashier Valley, Summit County, Colorado, at 12,000 feet, which 

 are considered by Bruce and W. H. Edwards to be a variety of Epipsodea, 

 though it is so different from it that, had I more specimens, I should be 

 inclined to consider it a different species, more especially as Epipsodea 

 does not appear to extend to such great elevations, or to vary much ; 

 though its range of altitude is very great. I have taken it in Idaho at about 

 2,000 feet elevation, and in the Yellowstone Park at 5,000 to 6,000 feet, 

 and have it from Colorado, taken by Bruce, as high as 9,500 feet. The 

 specimens above mentioned are somewhat smaller, and with rounder 

 wings, than the average of Epipsodea, but are best marked by the entire 

 absence of ocelli on either wing or on either surface, and the partial dis- 

 appearance of the red band." In the Synopsis of same paper, page 326, 

 Mr. Elwes puts this under the species name as "" ? Var. Brucei." 



Mr. Bean writes : " At Laggan, Epipsodea is moderately common in 

 June and early J uly, frequenting open, grassy flats of the Bow River valley.
