been found on all of the Commander Islands, the Aleutian Islands, 

 Kenai Peninsula, Sitka, Queen Charlotte Islands, and Vancouver

 other species of the same genus.

Not found by Dr. Hanna, though secured by Professor Kin- 

 caid on St. George Island. I have wing cases taken by myself 

 on Unalaska Island ; also specimens from Nome and Teller, 

 Alaska. It has also been taken at Bernard Harbor, Northwest 

 Territory (Can. Arctic Exped., 1919). These are the typical 

 palustris, agreeing perfectly with the typical form from Europe. 

 The subspecies canadensis Csy., which is found in the Hudsonian 

 and Canadian faunal regions more to the south, of which I have 

 specimens from Rampart, Tanana, and Dawson, is quite distinct, 

 as is also the subspecies geminatus Say, the common form in 

 the Eastern United States, and the subspecies perforatus Csy. of 

 British Columbia and Washington. The true palustris is also 

 found throughout Europe and Arctic Siberia.
