The records in British Columbia are from Kaslo (Cockle) : Eossland (Danby) : Yavetiby 

 (Moilliet) ; and a rather worn specimen from Fort Steele (W. B. Anderson). The type series 

 was taken in California and it occurs in Arizona and Utah.

Described from Vancouver Island. I have not seen any specimens from the Island, although 

 extensive collecting has been done on the southern portion of the Island, neither are there any 

 specimens in the Bryant collection from Wellington. A short series was taken in August by 

 Messrs. Day and Hanham on Mount McLean, and three specimens sent to me by Mr. Cockle, of 

 Kaslo, as Pctrophorus brncci Fern, turn out to be this species. Mr. Day records a specimen 

 of this species taken by his son at Dawson, Yukon Territory, in 1010. It occurs in Southern 

 California, and Barnes and Lindsey refer to this specias specimens taken in Colorado and Maine 

 which differ from typical specimens, but a.sree in all essential features.

 heavily sprinkled with white, and with some scattered blackish scales. Ground colour of inner 

 half, brown: of costal half, apparently grey-brown, the scales tipped with white: but this area 

 of the wing is greyish-white because of the predominating white scales. Costa with a grey-brown

 small blackish spot curving forward to costal dash in a slender line. First lobe with a black
