This paper contains notes affecting the classification of the Bruchidae of United States and Canada, a list of all species found north of Mexico, and a list of World genera and their type-species. The Mexican Merobruchus vacillator (Sharp) is added to the fauna of this area. Transferred from our list to that of Latin America are: Acanthoscelides californicus (Boheman), Megacerus eugenie new name for Bruchus ramicornis Boheman nee Erichson, and Mimosestes innotatus (Pic.). The following are synonymized: Spermophagus (Zabrotes) semicinctus Horn (1894) with Zabrotes subfasciatus (Boheman 1833); Bruchus subserripes Fall (1910) with Acanthoscelides compressicornis (Schaeffer 1907); Lithraeus electus Bridwell (1952) with Lithraeus elegans (Blanchard 1851); Bruchus alboguttatus Motschoulsky (1874) with Meibomeus musculus (Say 1831); Bruchus bivulneratus Horn (1873) with Bruchus abbreviatus, inadvertently validated by Say = Sennius abbreviatus (Say 1824); Bruchus nigrinus Horn (1873), B. nictitans Motschoulsky (1874), and B. depressus Fall (1912) with Sennius cruentatus (Horn 1873); Bruchus pythonicus Pic (1913) with Stator pygidialis (Schaeffer 1907); and Bruchus biguttatus Fabricius (1801) = Bruchus biguttellus Schoenherr (1833) with Callosobruchus chinensis (Linnaeus 1758). Original spellings of the specific names of two species are revived: Megacerus pygidalis (Motschoulsky) nee pygidialis Pic, and Megacerus discoidus (Say) nec discoideus: authors. Bruchus lividus J. E. LeConte 1824 is placed in our list as an unrecognized species. Thirty-five new combinations are proposed.
