Type locality: Vancouver Island, British Columbia (inferred from title of the paper), herein restricted to Tofino (see Lindroth 1961a: 173). Holotype [by monotypy] (♀) in MCZ [# 5854]. Etymology. The specific name was proposed for Henry and Joseph Matthews, brothers of the British Coleopterist Reverend Andrew Matthews [1815-1897] who specialized in small beetles. Henry and Joseph Matthews collected in British Columbia, including Vancouver Island. Note. There is a clear evidence of an inadvertent error in the original publication of the name matthewsii . It should have been spelled matthewsiorum since the species was proposed for two men together (see ICZN 1999: Article 31.1.2). However, the spelling matthewsii has been in used since LeConte proposed the name and I believe it should be preserved. The case should be submitted to the Commission for a ruling.
