The following reports the activities of the Montreal Branch of the Entomological Society of Ontario for the 73rd year.

Eight meetings were held during the 1945-46 season, six in the Lyman Room, Redpath Museum, McGill University and two in the Entomological Laboratory, University of Montreal. The average number present at the meetings was eleven, a reduction of four when compared with the figure for last year. This falling off in attendance can be accounted for in part, we believe, by the very severe weather experienced on the occasion of three of our meetings.
