Interpretive Summary: Most bees are active pollinators, but some make their living by parasitizing other bees, appropriating the pollen and nectar provisions for their own use. Among these is the genus Stelis that parasitizes carder, resin, and mason bees. Ten Stelis species new to science from the United States are named and illustrated. Since the bee hosts of these parasites are often quite specific, information on the hosts is provided.
Technical Abstract: Descriptions and diagnoses of ten new Nearctic species of Stelis are presented: S. alta, S. anasazi, S. anthocopae, S. broemelingi, S. imperialis, S. joanae, S. lamelliterga, S. occidentalis, S. paiute, and S. shoshone. Six of these species have been reared from trapnests. Host associations, all within the tribe Osmiini (Megachilidae), are provided.
