Distribution.

The range of this species extends from the Aleutians Islands and the Gulf Coast of Alaska south to northern California, northern Arizona (Coconino County, Eric van den Berghe pers. comm. 2009), and northwestern Wyoming [see Gidaspow 1968: Fig. 4]. Gidaspow (1968: 149) considered the possibility that the species ranges further east toward the Hudson Bay because of the presence in collections of several specimens labeled from "Hudson Bay Territory."
