this specimen are also darker than in the other examples and the yellowish-green 
submarginal spots are only faintly represented by a few scales of that colour. 
This specimen in the width of the band approaches rneadi 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 
chrysothernoides. 
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, July 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', 141st 
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 hoothi in the Entomological Record for 1905^ 
Ladue river, Yukon Territory, July 4, 1905, 1 male (J. Keele). Previously 
recorded with specimen from Lansing river as E. hoothi. 
Mayo valley, Yukon Territory, 1904 (J. Keele). In the Entomological 
Record for 1904- Fletcher recorded this specimen as E. hoothi, stating that it 
corresponded exactly with Elwes' fig. 5^. 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 hoothi. 
Kluane road, 135 miles from Whitehorse, 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 hoothii 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'* 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 1904 and 1905 which were 
recorded in the Entomological Record^ for 1904 and 1905. I have studied these 
specimens and am satisfied that they are not hoothi but similar to other specimens 
which we have determined as hecla glacialis McLach.
