Type locality: "Massachusetts and New York" (original citation), restricted to "Mass[achusetts]" by Lindroth (1961a: 157). Three syntypes in MCZ [# 696]. Dyschirius alternatus Hatch, 1949b: 117. Type locality: "Grand Coulee [Grant County], Washington" (original citation). Holotype in USNM. Synonymy established by Lindroth (1961a: 157). Distribution. This species is found from Prince Edward Island (Larochelle and Lariviere 1990a: 27) to south-central British Columbia (Lindroth 1961a: 157), south to eastern Washington (Hatch 1953: 68, as Dyschirius alternatus ), northern Utah (Utah County, USNM), Oklahoma (Custer and Latimer Counties, CMNH, UASM), and Long Island in New York (MCZ).
