14 1 Canadian Arctic Expedition, 1913-18 



Oeneis simulans, n. sp. 



Palpi black, upper fringe mostly 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 pa;le 

 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 but 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 McDunnougy, as will be 

 seen by comparing these with our figure on PL 1, fig. 5. 



Oeneis peartiae Edw. 

 Chionobas peartice Edw. : Butterflies of North America, III, pi. 14, 1897. 



Five specimens as follows: Bernard harbour, 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 IV, fig. 5. The underside of the same specimen is illustrated 

 on PI. II, fig. 6. 



The male genitalia are shown on PL I, fig. 7.
