Keys are provided to the five genera and 12 species of Philaenini in North America. Philaenus (Stål) is redefined to include only two species, one of which, spumarius L., 1758 (= rubra Capanni, 1894, = aurata Capanni, 1894, new synonymies) is represented in North America by three introduced subspecies: quadrimaculatus (Sch.) in eastern and western continental America, spumarius s.s. in Newfoundland, and tesselatus (Mel.) from one locality in southern Ontario. Philaenus parallels Stearns is removed to Paraphilaenus Vilb. as its sole Nearctic representative (new combination) and Philaenus lineatus (L.) belongs to the distinctive genus Neophilaenus Hpt. Philaronia Ball is represented in North America by five species: abjecta (Uhl.), canadensis (Wal.), fuscovaria (Stål) new combination, pauca n. sp. and superba n. sp. Philaenarcys new genus includes three species: bilineata (Say), 1831, new combination (= Ptyelus basivitta Wlk., 1851, new synonymy), killa n. sp., and spartina n. sp.
