Head with two supraorbital setigerous punctures dorsomedially to each eye; antennae inserted at sides of head, between eyes and base of mandibles; mandible without a setigerous puncture in scrobe; penultimate labial palpi have three or more setae anteriorly; mentum with median tooth; elytra with more or less angulate, usually dentate shoulders; elytral epipleura clearly crossed; last tarsal segment setose underneath. Amara is a large genus with considerable individual variability displayed by most species. The microsculpture and male genitalia are rather uniform throughout the genus.

Natural History

Over 100 species occur in North America. Most species are xerophilous, ocurring in open country with sparse vegetation. Adults are herbivorous and are often seen climbing vegetaton in search of fruits and seeds. At TESC examples of this genus have been collected in broadleaf forests and synanthropic habitats.
