Abstract
The following notes are based on material in the Canadian National Collection at Ottawa. A large proportion of the reared material was obtained by Dr. J. McDunnough at Bobcaygeon, Ont. in the course of his studies on the Lepidoptera of that region. His rearings of several species of Haploptilia yielded a number of parasites the habits of which have heretofore been little known in Canada. Other material mentioned below was reared by the writer and by various economic officers of the Entomological Branch staff. The determinations of the lepidopterous hosts of the Bobcaygeon material are by Dr. McDunnough.
