Excerpt: This paper, based on the examination of 1,879 specimens, serves to resolve the taxonomic problems involving the three North American species of Phragmatobia. The genus Phragmatobia, the ruby tiger moths, has had a checkered history since it was described by Stephens in 1829 (type, by monotypy, Noctua j'uliginosa Linnaeus, 1758). Although many species have been described in or transferred to this genus, in both the Old and New Worlds, most of them have been removed to other genera. By 1902 Dyar recognized only two North American species, a status since then unchanged (McDunnough, 1938; Forbes, 1960). Despite the recent stability of the names, there has been much confusion as to which names to apply to particular specimens. This problem is resolved below, with the description of a third North American species, long confused with the two named species.
