(e-mail: SJS: [email protected]) Abstract. — We report new Minnesota records for 13 genera and 100 species of ground beetles (Coleoptera: Carabidae), reflecting 21% and 31% increases, respectively, over records in the literature. There are now 76 genera and 433 carabid species recorded from Minnesota. New material was collected from sub-boreal forest study sites in northeastern and central Minnesota. We also surveyed 16 museum collections and private collections in the United States with an emphasis on collections in the north central region and those likely to contain Minnesota records. New generic records for Minnesota from the museum collections include Paratachys Casey, Nomius Laporte, Platypatrobiis Darlington. Gas-trellarius Casey, Lophoglossus LeConte, Pseudamara Lindroth, Panagaeus Latreille, Dicheirotrichus Jacquelin du Val, Discoderus LeConte, Leptotrachelus Latreille. Tetra-gonoderus Dejean, Apenes LeConte, and Axinopcdpiis LeConte. New species records from the field surveys in northeastern and central Minnesota include Notiophilus aquaticiis (Linnaeus), Sphaerodenis nitidicollis brevoorti LeConte, Trechiis crassiscapiis Lindroth. Bembidion mutatiim Gemminger & Harold, Bembidion ningatei Bland. Patrobits foveo-collis (Eschscholtz), Patrobus septentrionis Dejean, Pterostichus lueUuuirius (lUiger), Amara coelebs Hay ward, Pseudamara arenaria (LeConte), Bradyccllus semipubescens Lindroth, Harpalus ventralis LeConte. Agonum affiiie Kirby. and Agomim trigemimim Lindroth. In addition, we highlight the special role off. inelanariiis as an invasive beetle. Since many of the new records were based on specimens stored in research entomological collections, we recognize the significance of instilulioiial holdings as a source of infor-mation for studies of native biodiversity.
