The following list of specimens is supplementary to two previously published articles (1944, Canad. Ent. 76:163 and 1945, Canad. Ent. 77:214) on Essex County material. Appended to the list are miscellaneous records of 17 species captured in Ontario locations other than Essex County. These have been added to this paper since they are thought to be of noteworthy interest. The species in each part follow as closely as possible C.W. Leng's Catalogue of the Coleoptera of America north of Mexico.
