During the past twenty-five years, the writer has made spasmodic collections of Ichneumonoidea in various parts of Alberta, although, in the earlier years, prospects for getting them authoritatively determined were somewhat remote. In addition, smaller collections, chiefly one made by Dr. G. Salt and determined by Mr. R. A. Cushman in 1927, duplicate specimens taken by Dr. R. Salt in later surveys of insects associated with alfalfa, and specimens taken by a few university students, have been donated to the university collection.
