The Palearctic staphylinid beetles of the subfamily Aleocharinae occuring in North America are discussed. The record of Meotica exilis (Knoch) is regarded doubtful. The records of seven species doubtfully reported from North America are confirmed: Atheta amicula (Stephens), A. coriaria (Kraatz), A. fungi (Gravenhorst), A. islandica (Kraatz), A. pallidicornis (Thomson), A. palustris (Kiesenwetter) and Dinaraea angustula (Gyllenhal). Nine Palearctic species are recorded for the first time from North America: Atheta botanicarum Muona, A. dilutipennis (Motschulsky), A. harwoodi Williams, A. longicornis (Gravenhorst), A. nigricornis (Thomson), Geostiba circellaris (Gravenhorst), Gnypeta caerulea (C. R. Sahlberg), Dochmonota rudiventris (Eppelsheim) and Meotica apicalis G. Benick. The genera Homia Blackwelder and Schistoglossa Kraatz are occuring in North America. Pragensiella Machulka, 1941 is regarded a junior subjective synonym of Thecturota Casey, 1893. By the 16 species added here the number of Holarctic species of Aleocharinae amounts to 32.
