One new species, Acanthoscelides tridenticulatus, is described from Mimosa strigillosa Torr. and Gray in Texas, and from specimens collected in Louisiana and Texas.Erroneous records of Bruchidae having been reared from native Mimosa in the United States are corrected. These are: Merobruchus julianus (Horn) (Not synonym Bruchus ochreolineatus Fall) from Acacia greggii Gray, Not Mimosa fragrans; Acanthoscelides chiricahuae (Fall), Not Bruchus schrankiae Horn, from M. borealis Gray; and A. distinguendus (Horn) from Rhynchosia americana (Mill.) Metz, NOTM. strigillosa. All of these constitute new host records.The following new host records are reported: Acanthoscelides chiricahuae (Fall) from Mimosa biuncifera Benth. in Texas, New Mexico, Arizona, and Coahuilla, Mexico; and from M. dysocarpa Benth. and M. grahamii Gray in Arizona, A. quadridentatus (Schaeffer) from M. pigra var. berlandieri (Gray) Turner and M. strigillosa in Texas, and from M. pigra var. pigra L. in Nicaragua and Panama. A. speciosus (Schaeffer) from M. malacophylla Gray in Texas, from M. biuncifera in Arizona, and from M. galeottii Benth. in Morelos, Mexico. Stator pruininus (Horn) from M. biuncifera in Texas and Mexico; and from M. dysocarpa in Arizona.
