This species is a constant inhabitant of the Northwest Terri- 

 tories up to Lat. 58°. It seeks its food principally on the maple, 

 elm and ash, and north of Lat. 54°, where these trees do not

 {Ntlson.) This species ranges throughout the wooded districts of 

 Alaska. Along the Yukon River it is very common. (Turner.)
