Epipsodea was first known to me by examples taken by Mr. T. L. Mead, in 

 Colorado, 1871. He says, in Report of the Wlieeler Expedition: " This species 

 inhal)its the mountains of Colorado below timber line. Specimens were brought 

 from Fairplay by the Expedition. It begins to appear about the first week in 

 June, is common by the middle of that month, and remains luitil the last of 

 July." 



Several examples were received in 1883, by Mr. William M. Courtis, from 

 Judith Mountains, Montana, at about 4,000 feet elevation, in Jul}-. From Mr. 

 Ernest Stevenson, at Walla- Walla, southeast Washington, came some unusually 

 large specimens, late in June, 1885 ; others from Spokane Falls, in east Wash- 

 ington, by Dr. W. J. Holland. I have also received this species from St. Michaels 

 and Nushagak, Alaska; and have received eggs from Mr. Thomas E. Bean, at 

 Laggan, Alberta. On the other hand, I have not seen Epipsodea from south 

 Colorado, or New Mexico, or Arizona, or Utah, nor from the Sierra Nevada range 

 anywhere. So far as appears, it is confined to the Rocky Mountains from middle 

 Colorado northward to the Arctic sea, but flies over the lowlands in its northern- 

 most range, and may there have a wide distribution. Many examples from 

 Colorado are small, the wings expanding less than any seen from Alaska ; and 

 the laro-est have come from Washintrton. Throuohout its territory the two 

 principal varieties seem to be found, the banded and not lianded. 



Mr. Butler described the species from two individuals ■• from Rocky Moun- 

 tains," but the locality was not stated. 



Mr. Bruce writes : " I first met with Ejvpsodea in Platte Canon, Colorado, at 

 about 9,000 feet elevation. It frequents damp and boggy places where the gra.ss 

 grows i-ank and coarse. In such situations, up to nearly 12,500 feet, I found it 

 rather common. In one place, at the highest altitude named, a small stream of 

 muddy water from a mine had been conveyed in wooden troughs which emptied 

 into a basin-like depression ; in this place, being always moist, the grass and 

 flowers grew luxuriantly, and many species of butterflies were in profusion. 

 Ep'qysodea was plenty, and in almost all the examples I captured here, the ocelli 

 on 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 probably pecul- 

 iar to these hiu-h stations, where T have found it during three seasons, for, in the
