The 24 described and two undescribed species of Laphria Meigen (Diptera: Asilidae) currently known from eastern Canada (defined here as Manitoba eastward) and the adjacent United States are reviewed and keyed, with an emphasis on the Ontario fauna. Species in the related genera Dasylechia Williston and Lampria Macquart found in the same region are also keyed. Laphria cinerea (Back) and Laphria canis disparella Banks are recorded from Ontario for the first time. The female of Laphria sicula McAtee is included in a key for the first time.
