A male of Diachlorus ferrugatus (Fabr.) was recently captured at London, Ontario, by Mr. F. J. Hudson, an inspector for the Plant Protection Division, Science Service, of the Dominion Department of Agriculture. The specimen was taken during inspection of a case of Peperomia imported from the John's Nurseries, Apopka, Florida. As this seems to be the first recorded capture of this sex of the species, the following description of the specimen is offered. The Canadian National Collection contains two females, in poor condition, from Ellis Lake, Havelock, N.C., and these specimens together with Stone's description of the female have been utilized for purposes of comparison.
