Euscelis ohausi Wagner, a Palearctic deltocephaline leafhopper found mainly on Scotch broom (Cytisus scoparius; Fabaceae), was reported new to North America in 1971 based solely on late-instar nymphs from one locale in Oregon. We now confirm its establishment in North America based on collections from nine localities in Oregon, three in Washington, and four in British Columbia (first Canadian record). United States records are listed and mapped, and the adult is briefly described and illustrated. Characters are provided to distinguish E. ohausi from other species of the genus occurring in North America.
