Cychrus tuberculatus Harris, 1839

Cychrus tuberculatus T.W. Harris, 1839: 200. Type locality: «Oregon» (original citation, see page 199), restricted to "Portland [Multnomah County]" by Lindroth (1961a: 25). Syntype(s) apparently lost (Lindroth 1969a: 1108).

Cychrus pustulosus Casey, 1905: 160. Type locality: "Washington State" (original citation). Holotype [by monotypy] (♀) in USNM [# 46001]. Synonymy established by Roeschke (1907a: 228), confirmed by Lindroth (1961a: 25).

Distribution.

This species ranges from British Columbia, including the Queen Charlotte Islands and Vancouver Island, south at least to southern Oregon [see Gidaspow 1973: Fig. 7], possibly even Mendocino County in northern California (Roeschke 1907a: 229). The record from “Alaska” (Roeschke 1907a: 229) is likely in error.
