Bembidium stephensii Crotch, 1866: 110. Replacement name for Bembidium affine (Stephens, 1835). Etymology. The specific name honors the British entomologist James Francis Stephens [1792-1852] who worked as a clerk in the admiralty at Somerset House in London and later at the British Museum. Stephens devoted a large part of his life to study British insects. His collection was purchased by the British Museum and his fine library was acquired by Henry Tibbats Stainton who continued Stephens’ practice of allowing fellow entomologists to use his library on Wednesday evenings. Stainton produced a catalogue of Stephens’ books in 1853, under the title Bibliotheca Stephensiana .

Bembidium canadense Hayward, 1897: 77. Type locality: "near Ottawa [Ontario], Canada" (original citation). One syntype [2 originally cited] in MCZ [# 16286]. Synonymy established by Lindroth (1954b: 125).

Distribution.

This Palaearctic species is adventive in North America where it is known from Newfoundland (Lindroth 1955a: 58) to northeastern Wisconsin (Forest County, CMNH; Messer 2010: 36), south to northern Ohio (Lee 1994: 58) and Massachusetts (Lindroth 1955a: 58). The records from "Rhode Island" and “Virginia” (Bousquet and Larochelle 1993: 136) need confirmation. The first inventoried specimen collected on this continent was found in Ottawa, Ontario in 1891 (Lindroth 1963b: 323).
