I had recently the pleasure of receiving from Mr. J. I. Beaulne of Quebec City an interesting dipterous insect for identification. The locality label attached to the specimen read “Lachine, Que., 4, IX, 43, J. I. Beaulne.” The insect belonged to the genus Acrocera of the family Acroceridae and did not match any of the specimens in the collection of the University of Montreal. I sent it to Mr. G. E. Shewell of the Department of Agriculture, Ottawa, for identification. Mr. Shewell kindly replied, stating that the fly was Acrocern steyskali Sabr., a new record for Quebec. He further stated that the species was described quite recently from northeastern United States material and that he did not think it had been recorded from anywhere in Canada.
