One day during the summer of 1873, five ardent entomologists resident in the city of Montreal were separately engaged in collecting specimens of their favourite orders on the woody slopes of Mount Royal, in those days far removed from the city itself. Meeting in the course of their rambles, these amateurs joined together to pursue their hobby, and in this way the formation of a Montreal branch of the Entomological Society of Ontario was discussed and finally arranged.

The Entomological Society of British Columbia was founded January 8th, 1902, by a small but ardent group of entomologists living in the environs of Vancouver and Victoria. The original document of organization came to the writer's hand only a year ago from Mr. W. Downes of Victoria, who in turn received it from Mr. Francis Kermode, Director of the Provincial Museum. It was found among some old papers of the museum.
