Species recognition. This species is easily distinguished from all other northeastern Eumenes by the ferruginous markings on the scape and mesosoma. The extralimital E. smithii (known from North Carolina, Tennessee, Missouri) is similar but has a fine transverse pronotal carina and has only very short hair on segment 1 of the metasoma.

Variation. Fore wing length not studied (♂♂), 11–13 mm (♀♀). Variation otherwise not studied.

Distribution. Canada: AB, newly recorded for BC. Western half of U.S. east to MN, IA, MO (Krombein 1979). Mexico: Tamaulipas, Baja California (Rodríguez-Palafox 1996). The western ssp. oregonensis Bequaert, 1938 occurs in ID, WA, OR and NV.

Biology. Builds mud nests that are attached to vegetation (Isely 1914).
