Lepidoptera 9 1 
Eurymus eurytheme kootenai Cockle. 
Colias kootenai Cockle: Can. Ent. XLII, 203, 1910. 
Barnes and McDunnough^ have recently separated the forms which they 
considered should be arranged under eurytheme. Regarding kootenai which they 
refer to as being evidently the spring form of British Columbia, it is of interest 
to include here the following records: Felly river, at mouth of Campbell creek, 
Yukon Territory, male, July 8, 1907 (J. Keele); Felly river, near Hoole river, 
Yukon Territory, male, July 5, 1907 (J. Keele); Klotassin river area, Yukon 
Territory, 62° 31' to 63° 06'- long. 137° 30' to 139° 30', summer, 1916, male and 
female (D. D. Cairnes). 
The above authors, in the publication referred to figure two males and one 
female, one of the former being of a specimen from Atlin, B.C., which is adjacent 
to the Alaskan border. 
Eurymus Christina Edw. 
Colias Christina Edw.: Proc. Ent. Soc. Fhil., 11, 79, 1863. 
Mr. Jos. Keele, of the Department of Mines, Ottawa, has on several occasions 
collected interesting specimens of lepidoptera in northern regions. In 1908 he 
met with this species on the Mackenzie river opposite Gravel river. Northwest 
Territories, July 17, 18, 1908, 6 males, 5 females. A single female was also 
collected by Dr. D. D. Cairnes on the west side of Lake Kluane, near Jacquot's 
road house, Yukon Territory, Aug. 2, 1914. These specimens are similar to 
others taken in more southern regions in the provinces of Alberta and Saskatche- 
wan. One of the specimens is apparently the form gigantea Stkr. The species 
was described from material collected '' at the portage of Slave river." 
In 1888, Mr. F. Bell collected a cohid at Fort Simpson, Northwest Terri- 
tories, and this was determined by W. H. Edwards as occidentalis, and recorded 
as such by Fletcher-. Barnes and McDunnough^ state that possibly the Fort 
Simpson specimens mentioned by Scudder in his description of occidentalis really 
belonged to a yellow form of Christina, and for this reason they would restrict 
the name occidentalis to the Vancouver island form which, while close, they 
mention can at once be distinguished by the much greater suffusion of black at 
the base of both wings on the upper side, approaching in this respect chrysomelas 
Hy. Edw. 
The specimen collected by Mr. Bell and named occidentalis for Fletcher by 
Edwards certainly lacks the suffusion of black at the base of both wings on the 
upper side and is thus similar to christina as we know the latter. 
Eurymus pelidne Bdv. 
Colias pelidne Bdv.: Icones, pi. VIII, 1832. 
In the Canadian National collection there are twelve specimens which we 
have determined as this species. These specimens were taken as follows: 
Limestone harbour, opposite northern part of Big island, Hudson strait, July 
24, 1897, male (R. Bell); head of Kaliktookduog inlet, north side of Hudson 
strait, July 26, 1897, male (R. Bell) ; Sore-head river, east coast of Hudson bay, 
August 15, 1898, male (A. P. Low); Hannah bay, Hudson bay, female; Koong- 
neow inlet, Hudson strait, July 29, 1897, female (R. Bell); Labrador, July 9, 27, 
5 males (A. P. Low); Little Charlton island, James bay, July 14, 1884, male 
(J. M. Macoun).
