This is the first major revision of North American Vespinae and Vespinae systematics in general. This review provides keys to the North American species as well as provides extensive distributional data and biological notes. Additions and corrections to this publication contaning distributional, biological, and nomenclatiorial information was added in two subsequent publications (1935 and 1941). Links are provided to those below.

Additionally provided below is Bequaert's divisions of the Vespinae which is a prequel to this review and deals with all known species of the Vespinae worldwide that were known at the time.
