Four species of the Genus Grammotaulius, one of which is now considered a synonym, have been recognized in North America. These have been recorded only from Greenland, Canada, and northwestern United States. In August, 1940, Dr. C. E. Mickel and Mr. H. E. Milliron collected a series including both sexes of a new species in Colorado.
