We report 39 ground beetles new to five states in the upper midwestern United States. These species records include 19 new to Illinois (all but one from Lake County), 11 from Iowa, three from South Dakota, eight from Wisconsin, and two from Michigan. (Three species are new to more than one state). Enigmatically disjunct collections include the myrmecophile, Helluomorphoides nigripennis from western Illinois, known previously only from the Atlantic and Gulf coastal plain and piedmont, and Chlaenius amoenus, reported only from southeastern states and now from northeast Iowa.
