The advent of another collecting season finds me with a very large proportion of my last year's captures still undetermined, and in many instances even unexamined. A few remarks, however, in regard to my success with the Hymenoptera may induce some of our younger members to pay more attention to this order. Probably 500 species were collected, a large proportion of which were of the smaller forms, and it seemed, indeed, that many of the larger species were much less numerous than in some seasons. Special attention was given to the collection of the microhymenoptera, for these are so poorly represented in canadian collections. In making a rough summary of the species, I find about 125 species belonging to the Aculeata, and 100 to the Phytophaga the remainder being distributed among the different families of parasitic forms. There are many interesting additions to my collection, and many gaps have been filled in. Mr. Ashmead's monograph of the Proctotrypids has made it abundantly evident that the knowledge of the Canadian species was very limited, and I made a special effort to obtain as many examples as possible. I took altogether about 350 specimens, and now find that over 50 species are represented. This will give any collector an idea of what he may expect to secure if he have the necessary patience to preserve and mount so much small and inconspicuous material.
