The eastern Palearctic bruchine seed beetle Bruchidius terrenus (Sharp) (Coleoptera: Chrysomelidae: Bruchinae), a specialist seed predator of mimosa or silk tree (Albizia julibrissin), is reported for the first time in North America based on collections from seven southeastern states. This is the third Asian insect species recently reported from A. julibrissin in the United States. A diagnosis, description, photographs of the adult, a summary of the known U.S. distribution, notes on seasonal history, and a revision to an existing key to North American Bruchidius are presented.
