Three specimens of a species of leafhopper new to the Niagara Peninsula were collected during 1956 along the wooded bank of Niagara River below Queenston, Ontario; they were identified by Mrs. C. J. Williams, Entomology Division, Ottawa, as Orientus ishidae (Mat.) and are in the Canadian National Collection. According to Oman (1949), this is an introduced Japanese species which lives on willow and is widely distributed. Presumably Oman's statement is based on collections made in the United States as Mrs. Williams stated (in litt.) that this was the first record from Canada.
