Distribution.

This species ranges from central Alaska to eastern Alberta, including western Northwest Territories, south to west-central Montana, northern Idaho, and northern Oregon [see Ball 1963: Fig. 2]. The records from northern Colorado (Packard 1877: 811; Wickham 1902: 236; Armin 1963: 218; Elias 1987: 632, as Pterostichus fatuus ) need confirmation. Fossil remnants from a Plio-Pleistocene sequence have been unearthed in northwestern Greenland ( Böcher 1995: 28).
