During 1954, I had the opportunity of examining a large collection, circa 3,500 of unidentified Corixidae which had been accumulated in the Canadian Department of Agriculture over a period of years. These notes consist of a list of species identified, with observations where pertinent when these records are new state or country records compared with the full lists of localities given in H. B. Hungerford's ‘The Corixidae of the Western Hemisphere’ 1948, Univ. Kansas Sci. Bull. Vol. XXXII, pp. 1-827.
