BRENTHIS FRIGGA var. IMPROBA (Butler). 



The t>-pe came from Mackenzie River delta. 



Hanbury secured two pairs on the Barren Grounds, 114"^ W., 67° 

 40' N., and a male at Point Epworth in 1902, which Elwes considers 

 t^^pical of this form.'^' Butler Ixised his description of Argynnis 

 improba upon specimens taken l)y Richardson between latitude 67i° 

 and 68^, in the Mackenzie River delta. These specimens, much worn, 

 were presented to the British Museum by Richardson in 1851. 



PHYCIODES BATESII (Reakirt). 



A specimen of Plnjc)<Hle>< which 1 collected at Fort Providence early 

 in July, 1903, seems to be referable to P. hatesii, although greatly 

 extending the previously recorded range of that species. Compared 

 with specimens of P. tharos from New York, the Fort Providence 

 specimen differs in having a pale yellow or almost white band beyond 

 the cell of the fore wings. The l)lack bars in the cell of the primaries 

 also do not extend below the median vein. 



PHYCIODES THAROS (Drury). 



Represented in Mr. Preble's collection by a fresh female from Fort 

 McPherson, Juh^ 8, 1904, and a battered example from the mouth of 

 the North Nahanni River, Jul}" 25. 



Previousl}" recorded by Scudder, who gives the two following refer- 

 ences: "Mackenzie River (Edwards); Upper Liard River (Dawson).'"* 

 Doctor Fletcher records specimens collected by R. G. McConnell, of 

 the Canadian Geological Survey at the Devil's Portage, Liard River 

 (longitude, 120 " 10'), in 1888.^ Butler records two males and a female 

 of this species which were collected at the Rapids of the Drowned, 

 Slave River, June 29, 1892, by Miss Elizal)eth Taylor.''

 Drowned, Slave River, where it was collected July 1, 1892, bj^ Miss 

 Elizabeth Tajior.^'
