14 I Canadian Arctic Expedition, 1913-18 
Oeneis simulans, n. sp. 
Palpi l)Iack, upper fringe mojstly white. Antennae brown, with conspicuous 
white scales on inner side, knob orange-brown. Body blackish. The upperside 
of the wings are immaculate, pale brown in colour, almost drab^, the maculation 
of the underside showing through particularly on the secondaries. Sex mark 
faintly indicated. Costa whitish, mottled with black. Underside: primaries 
dull grey-brown, costa and apex whitish with black mottlings; secondaries pale 
grey-brown inclining to whitish, particularly on outer half, and mottled and 
streaked with dark brown, blackish at base and along inner angle. Median band 
rather indistinct ])ut noticeably defined by blackish shading both on its inner 
and outer margin. Maculation in general similar to semidea but not so contrast- 
ing as in this latter species and without the conspicuous whitish areas. Fringes 
whitish, checkered with pale brown. 
Alar expanse, 43 mm. 
Type, a male, from Bernard harbour, Northwest Territories, July, 1915 
(F. Johansen). Two paratypes from the same locality and bearing the same data. 
In two of these latter the maculation on the underside of the secondaries is more 
diffused than in the type, the median band being defined on the outer margin 
only, the area between this and the base being almost wholly suffused with 
blackish-brown. A third specimen, which I also associate with the above, 
differs from the type on the underside of the secondaries in having the median 
band more heavily suffused with dark brown and more sharply defined with 
whitish scales on both its inner and outer margin. The outer margin is distinctly 
angled and in this respect differs from the type. These specimens have a wing 
expanse of 37-40 mm. The underside of the type specimen is shown on Plate 
II, fig. 5. All the types are in the Canadian National collection. 
With the above males are two females from the same locality which are 
being placed tentatively with this species. The underside of both of these 
specimens is much darker than that of the males being more heavily mottled 
and streaked with dark brown. In one of the females there is hardly, any 
indication of a median band but in the other female the band is noticeably 
present being rather heavily bordered on the outer margin with blackish-brown. 
The above specimens of 0. simulans were collected at the same locality as 
were the specimens of 0. semidea arctica, from which on superficial characters 
they cannot be separated. The genitalia, however, are quite distinct from any 
of those figured by Elwes and Edwards^ or Barnes and McDunnough^, as will be 
seen by comparing these with our figure on PI. 1, fig. 5. 
Oeneis peartiae Edw. 
ChionobaH peartid Edw.: Butterflies of North America, III, pl. 14, 1897, 
Five specimens as follows: Bernard harljour, Northwest Territories, July, 
1916, three males, 1 female (F. Johansen) ; Chantry island, near Bernard harbour, 
Northwest Territories, August 7, 1915, 1 male (F. Johansen). 
These specimens resemble fairly closely, Edwards' figs. 5, 6, 7, and 8, plate 
XIV, in his Butterflies of North America, Third Series, part XVII, 1897. In the 
female there is a faint yellowish spot between viens 5 and 6 on each primary 
towards the apex. This spot is also present on the underside. This specimen 
is shown on Plate \W fig. 5. Tlie underside of the same specimen is illustrated 
on PI. II, fig. 6. 
The male genitalia are shown on PI. I, fig. 7.
