Abstract

Keys to adults and puparia of three Nearctic species are given, with an outline of distribution of each species. Melangyna tenuis (Osburn) and M. cincta, American authors not Fallén, are treated as synonyms of M. triangulifera (Zetterstedt). A lectotype is designated for M. guttata (Fallén). A new species is described from British Columbia.
