Abstract
The type specimens of five species of Eleodes described by Francis Walker from British Columbia, Canada, were studied in order to establish their true identity. The synonymy of Eleodes convexicollis Walker and E. conjunctus Walker with E. obscurus (Say); that of Eleodes latiusculus Walker with E. humeralis LeConte; and that of Eleodes binotatus Walker with Eleodes hispilabris (Say) is confirmed. Eleodes subtuberculatus Walker = Eleodes parvulus Blaisdell, new synonymy, and not a synonym of E. granulatus LeConte. Only in the latter case is a Walker name senior to the name currently in use.
