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 : Pelly river, at mouth of Campbell creek, 

 Yukon Territory, male, July 8, 1907 (J. Keele); Pelly 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. Phil., II, 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 coliid 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 KaUktookduog 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).
