The woodwasp, Xiphydria canadensis Provancher, is a rare insect restricted to northeastern North America. Provancher (1875) based his original description on a single female collected at St. Hyacinthe, Quebec. In his recent revision, Smith (1976) saw only five females. On 7 August 1977, I collected a specimen of this large and distinctive species on the north side of Hwy. 60, at Mile 12.7, just west of the Park Museum in Algonquin Provincial Park, Ontario. This collection constitutes the first record for this species in Ontario.
