The collection of lepidoptera made by members of the Southern Party 

 of the Canadian Arctic Expedition during the years 1913 to 1916, is composed 

 largely of butterflies. The material was collected chiefly by Mr. Frits Johansen, 

 although a number of specimens were taken by Mr. D. Jenness and Mr. J. J. 

 O'Neill, other members of the expedition. The localities where the lepidoptera 

 were collected are in some instances the same as those visited by Mr. David T. 

 Hanbury, whose collections were reported upon by Elwes and Hampson^. A 

 small number of specimens of the families Pyrahdse, Pterophoridse, and Tortri- 

 cidse were brought back, but these are in such poor condition that it is impossible 

 to determine them. In addition to the collection made by the Southern Party, 

 I have also examined a small collection brought back by the Northern Party 

 made on Victoria island and Melville island. 



In the National Collection of Insects at Ottawa there are a number of 

 species which were collected in Arctic regions by oSicials of the Geological 

 Survey of Canada and which were not obtained by members of the Canadian 

 Arctic Expedition. It has been thought advisable to include the records of 

 such captures in this report. 



In the spring of 1917, I had an opportunity of studying portions of the 

 Barnes' collection of lepidoptera, at Decatur, 111., which is undoubtedly one 

 of the most complete collections of North American lepidoptera in existence. 

 On this occasion I compared some doubtful material with specimens in the 

 collection. I received many favours while in Decatur, not only from Dr. Barnes 

 himself but from Dr. J. McDunnough. To both of these gentlemen I am much 

 indebted. A few other specialists were consulted with regard to doubtful 

 species and such assistance as was received is acknowledged in the text. 



In the following pages nine species are described as new, in addition to 

 which two new varieties are recognized. The majority of these new species 

 and new varieties were collected by members of the Canadian Arctic Expedition. 



The photographs from which Plates I to III, inclusive, were made, were 

 taken by Mr. A. E. Kellett, Artist Assistant, Entomological Branch, Department 

 of Agriculture, Ottawa. 



The arrangement of the species follows Barnes and McDunnough's recently 

 issued Check List of the Lepidoptera of Boreal America. 



FAMILY PAPILIONIDAE.

No specimens of this butterfly were met with by members of the Canadian 

 Arctic Expedition. In the National Collection of Insects at Ottawa there are 

 specimens from: Valley of Mayo river, Yukon Territory, July, 1904 (J. Keele); 

 Gravel river, near Twitya river. Northwest Territories, June 28, 1908 (J. Keele) ; 

 three miles below summit of Chilkoot pass, July 15, 1886 (McDougall) ; between 

 latitudes 67° 25' and 66° 30', long. 141°, June 12-27, 1912 (D. D. Cairnes). 



Mr. Keele reported that this butterfly was quite common along the shores 

 of Mayo lake and valley of Mayo river, Yukon, during July and August, 1904.
