The Lepidoptera collected by the Canadian Arctic 
Expedition, 1913-18.

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 Pyralidse, Pterophoridse, and Tortri- 
cidas 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 officials 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 speciahsts 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.

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.
