Abstract

Four species of Orius Wolff, a Holarctic genus, are known from the Nearctic region. Orius insidiosus (Say) is known from midwestern and eastern United States and eastern Canada, while O. tristicolor (White), shown here to be a valid species, is transcontinental in North America. O. minutus (L.), a common species in the Palaearctic region, is known from western North America. O. pumilio (Champ.) occurs in Florida. The distinguishing characteristics of the species are given, and a key is provided.
