Extract
The species of Rhaphium Mg. (s.l.) may be divided, for convenience, into two group—those with white-faced males and those with black-faced males. Since the North American species of the genus were last revised (Curran, 1926, 1927), 13 species belonging to the former group have been described. In this paper one species with black-faced males is described as new, one is recorded from the Nearctic region and one from Canada for the first rime, and one species with white-faced males is also recorded from Canada for the first time.
