These specimens are in general similar to examples collected in Alberta and 

 British Columbia. The two examples one from Dease lake, and the other from 

 near Dease lake, were submitted by Fletcher to W. H. Edwards, and the name 

 " freya " given. 



Three other specimens, males, all below average size, taken in northeastern 

 Alaska, collected with other species, the label covering all reading " hit . 59° 30' 

 and 141st meridian; lat. 69° 40' and 141st meridian; June-July, 1912, (J. M. 

 Jessup)" in the Canadian National collection, I also associate with freija.

Thirty-two specimens as follows: Barter island, north coast of Alaska,

In the National collection at Ottawa are two other specimens, one a female 

 collected at Kalik-took-duag inlet, north side of Hudson strait, July 27, 1897 

 (R. Bell), the other, a male, from cape Chidley, Hudson strait, 1885 (R. Bell). 



The males do not show any material variation. In size they have a wing 

 expanse of from 36 to 43 mm. The upperside of all specimens is similar. The 

 general colour of the underside of the secondaries of two of the specimens inclines 

 to a uniform reddish shade similar to the underside of the primaries. In the 

 females there is a difference in wing expanse, the variation being from 37 mm. 

 to 45 mm. The colour of the upper side of the primaries of this latter sex varies 

 in the specimens from a pale reddish-yellow to a dull bluish-white or dull purplish- 

 white. In a few of the specimens many of the scales particularly towards the 

 hind angle are, under a lens, seen to be decidedly bluish. The reddish bands on 

 the underside of the secondaries vary in colour from pale red similar to the 

 general colour of the primaries beneath, to dull brownish-red. 



Mr. Jenness who collected the specimens on Barter island states that they 

 were captured on the tundra early in the afternoons, in most instances between 

 1 and 2 p.m. in bright sunshine, the temperature varying from 34° F. to 56° F., 

 the majority being taken when the temperature was about 50° F. 



In addition to the above specimens, thirty-four examples were brought hack 

 by the Northern Party of the Canadian Arctic Expedition, from the following 

 localities: Armstrong point, Victoria island, Northwest Territories, June 20 to 

 July 11, 1916, 15 males, 11 females (J. Hadley); Walker bay, Victoria island, 

 Northwest Territories, July 6, 1917, 4 males,. 2 females (J. Hadley); Melville 

 island, main base, August 4 (?), 1916, one male ( Y. Stefansson); near cape Ross, 

 Melville island, Northwest Territories, about June 20, 1916, 1 male (Caste! and 

 Emiu). These specimens in general are similar to the examples collected by 

 members of the Southern Party. 



The underside of a female from Barter island, Alaska, is shown on PI. V, 

 fig. 2. On the same plate is also shown the upper side of a male and a female 

 from the same locality (figs. 3 ana 4).
