12 i Canadian Arctic Expedition, 1913-18 



Oeneis jutta Hbn. 



Oeneis jutta Hbn.: Eur. Schmett, f. 614, 1800. 



In the Canadian National collection are specimens from the following Yukon 

 localities: North Fork Stewart river, Yukon Territory, June 22, 1905, 1 male 

 (J. Keele); Klotassin river area, Yukon Territory, lat. 62° 31' to 63° 06'; long. 

 137° 30' to 139° 60', summer 1916, 1 male (D. D. Cairnes); Ladue river, Yukon 

 Territory, July 4, 1905, 1 male, 2 females (J. Keele); Lansing river, Yukon 

 Territory, June 24, 1915, 1 female (J. Keele). 



In all of these specimens excepting the male, taken on the Ladue river, the 

 median band on the underside of the secondaries is present. In the exception 

 the band is not definitely marked and in general may be referred to the var. 

 alaskensis Holl. The specimens on the whole are smaller than jutta which occurs 

 commonly at the Mer Bleue, Carlsbad Springs, Ont., a favourite collecting 

 ground near Ottawa. 



Oeneis taygete Hbn. 

 Oeneis taygete Hbn.: Samml. Ex. Schmett, 1816-24. 



One specimen, a male, as follows: Bay southwest of cape Krusenstern, 

 Northwest Territories, July 3, 1916 (D. Jenness). 



In the Canadian National collection at Ottawa there are nine other 

 specimens bearing locality records as follows: Kluane road, 96 miles from 

 Whitehorse, near Marshall creek, Yukon Territory, June 15, 1914, 1 male 

 (D.X>. Cairnes); Sit Down creek, lat. 65° 40',long. 141°, July 9, 1912, 1 female 

 (D. D. Cairnes); Nation river, lat, 65° 31' (1700-2500 ft.), July 17, 1912, 1 

 female (D. D. Cairnes); Siwash creek, Yukon Territory, lat. 65° 57', long. 

 141°, June 30, 1912, 1 female (D. D. Cairnes); one other specimen evidently 

 from the Yukon Territory, but without definite data; Labrador, male; King 

 George sound, south side Hudson strait, July 16, 1897, 2 males, 1 female 

 (R. Bell). 



In the males the median band on the underside of the secondaries is very 

 distinct, in the females less so. The whitish spots near the margin on the hind 

 wings beneath, are conspicuous on most of the Yukon specimens and equally so 

 on the Labrador specimen. 



Holland has given a rather good figure of the specievs in his Butterfly Book 

 pi. XXVII, 6, the specimen illustrated being from Nain, Labrador. In none of 

 our specimens is the pale yellowish submarginal band on the upperside so marked 

 as indicated in Seitz's figure 50g, vol. v — The Macrolepidoptera of the American 

 Faunistic Region. The submarginal area of the specimens listed above is, in both 

 sexes, similar in colour to the general colour of the primaries. In some of the 

 examples the yellowish spots on the upperside of the secondaries near the margin 

 are very conspicuous. The general colour of the upper surface of the Labrador 

 example is of a golden-brown shade, while that of the Bernard harbour specimen 

 and other males, is of a darker shade of brown. The median band on the 

 underside of the secondaries while conspicuous in all the specimens indicates 

 considerable variation not only in width but also in shape. The number of 

 white scales on both sides of the median band also varies. In all the specimens 

 the veins are white-lined. 



The genitalia of the specimen taken on the Kluane road, 96 miles from 

 Whitehorse, Yukon Territory, are shown on Plate 1, fig. 1.
