Abstract

Three new species are described; two European species, tringarius L. and lineola Fabr., are recorded for the first time; and the previously described species are redefined and new distribution records presented, with a key to the eastern species. Rhagio hirtus Loew is recognized as a good species, R. boscii Macquart and Xylophagus fasciatus Say are synonymized with albicornis Say, and R. intermedius Walker is synonymized with R. vertebratus Say. The three new species are R. dichromaticus from Louisiana, recognized by its extremely dark coloration; R. floridensis from Florida and Georgia, with yellow thorax and distinctively patterned wings; and R. orestes from Great Smoky Mountains National Park, which is close to hirtus but separable by the darker thorax and abdomen.
