| abstract | A new species, Ereynetes (Ereynetes) boharti, from Wyoming is described and illustrated. This species was common in artificial nesting blocks containing numerous dead prepupae of the alkali bee, Nomia melanderi Ckll. The latter were being consumed by large numbers of an undescribed Caloglyphus. Nine species of Ereynetinae are now known from North America. A key to these species is given. |
