New adult host records of Agrilus langei Obenberger, A. pilosicollis Fisher, and Dicerca mutica LeConte (Coleoptera: Buprestidae) are reported. The known geographic range of A. pilosicollis is expanded from the type location in Kansas south to Texas and east to North Carolina. Images with key characters of each of the three species are included.

Among the nearly 800 species of buprestids in North America (north of Mexico) are those known from very few specimens. Distribution and plant host information for such species is understandably limited and, in many cases, completely unknown (Nelson et al. 2008). A knowledge of host utilization is often the first step in under­standing the life history of such buprestid species. Adult host records of rarely encountered buprestids can be useful starting points to determine larval hosts, as adults of non-anthrophilous genera are frequently found feed­ing on larval plant hosts. Herein we report distribution and adult plant host records that may prove useful in future study of Agrilus langei Obenberger, A. pilosicollis Fisher and Dicerca mutica LeConte.
