<jats:title>Abstract</jats:title><jats:p>Species of<jats:italic>Braggia</jats:italic>Gillette and Palmer (Hemiptera: Aphididae: Aphidinae: Aphidini) feed on various buckwheat,<jats:italic>Eriogonum</jats:italic>Michx. (Polygonaceae), species in western North America. Two new species,<jats:italic>Braggia columbiana</jats:italic>Pike<jats:bold>n. sp</jats:bold>. from Washington and Oregon and<jats:italic>Braggia longicauda</jats:italic>Pike<jats:bold>n. sp</jats:bold>. from Washington, Oregon, and northern California, are proposed. Descriptions, diagnoses, illustrations, mitochondrial cytochrome<jats:italic>c</jats:italic>oxidase subunit 1 “barcode” sequences, a key to the species of<jats:italic>Braggia</jats:italic>, and notes on biology, distribution, and parasitoid associations are provided.</jats:p>
