In the course of working on new species of North American Phyllophaga Harris, 1827 (Coleoptera: Scarabaeidae: Melolonthinae) some synonyms have been found and are proposed here. New synonymies: Phyllophaga knausii (Schaeffer, 1907) is synonymized with Phyllophaga sociata (Horn, 1878); Phyllophaga chippewa Saylor, 1939 is synonymized with Phyllophaga rugosa (Melsheimer, 1845); and Phyllophaga falta Sanderson, 1950 is synonymized with Phyllophaga bipartita (Horn, 1887). Lectotypes are here designated for the following species: Listrochelus knausii Schaeffer, Listrochelus sociatus Horn, and Lachnosterna bipartita Horn. A neotype for Ancylonycha rugosa Melsheimer is here designated from the Horn Collection.
