Lepidoptera 7 i 



this specimen are also darker than in the other examples and the yellcywish-greeD 

 submarginal spots are only faintly represented by a few scales of that colour. 

 This specimen in the width of the band approaches meadi Edw. The females 

 vary in size from 42 to 51 mm. 



Specimens of both sexes have also been compared with Verity's figures of 

 hecla. One or two, possibly more, of our females may be the same as his 

 chrysothemcrides. 



Seven specimens, males, of the same species were brought back by the 

 Northern Party of the Canadian Arctic Expedition. These were collected at 

 Armstrong point, Victoria island, Northwest Territories, .Julv 1-10, 1916 

 (J. Hadley). 



In addition to the above specimens there are 21 other examples in the 

 Canadian National collection taken as follows: 



Klutlan glacier, international boundary, June 21, elevation 7,500 feet, 1 

 male (E. W. Nesham) ; Alaska, lat, 59° 30', 141st meridian— lat. 69° 40', 14 Ct 

 meridian, June-July, 1912, 2 males, 1 female (J. M. Jessup). This latter is a 

 white female, and is apparently pallida S. and M. 



Lansing river, Yukon Territory, June 24, 1905, 1 male (J. Keele). This 

 specimen was recorded as Eurymus booth! in the Entomological Record for 1905 1 . 



Ladue river, Yukon Territory, July 4, 1905, 1 male (J. Keele). Previously 

 recorded with specimen from Lansing river as E. booth i. 



Mayo valley, Yukon Territory, 1904 (J. Keele). In the Entomological 

 Record for 1904 2 Fletcher recorded this specimen as E. boothi, stating that it 

 corresponded exactly with Elwes' fig. 5 3 . Unfortunately this specimen is in very 

 poor condition. I have compared it with Elwes' figure referred to, and would 

 determine it as hecla glacialis not boothi. 



Kluane road, 135 miles from Whitehcrse, Yukon Territory, June 21, 1914, 

 1 male, 1 female (D. D. Cairnes). 



Near mouth of Nansen creek, head of Nisling river, Yukon Territory, July 

 4, 1914, 2 males, 1 female (D. D. Cairnes); White river district, Yukon 

 Territory, lat, 61° 55', long. 141°, July 16, 1913, 1 male (D. D. Cairnes); 

 Tatonduk river, international boundary, lat. 65° 02', August 3, 1912, 1 male 

 (D. D. Cairnes); Tinder creek, Yukon territory, July 25, 1912, 1 female (D. D. 

 Cairnes); west branch of the Thelon river, Northwest Territories, July 6, 1900, 

 1 male (J. Tyrrell); Sore-head river, east coast of Hudson bay, August 15, 

 1898, 3 males, 2 females (A. P. Low). 



Eurymus boothi Curtis. 



Colias boothii Curtis: Ross' Nar. Second Voyage N.-W. Pass., App., 65, 1835. 



Six specimens, all males, from the following localities: Bernard harbour, 

 Northwest Territories, July 14, 1916, 5 specimens (F. Johansen); Port Epworth, 

 Coronation gulf, July 15, 1915, one specimen (J. J. O'Neill). 



I have compared these six specimens with the original figures and description 

 of boothi and cannot associate them with any other species. The specimens have 

 also been compared with Elwes' figures 1 of specimens collected at Port Epworth, 

 Barren Grounds and Gray's bay. In the collection of the National Museum at 

 Ottawa are three specimens taken in the Yukon in L904 and 1905 which were 

 recorded in the Entomological Record'' for L904 and 1905. 1 have studied these 

 specimens and am satisfied that they are not boothi but similar to other specimens 

 which we have determined as hecla glacialis McLach.
