Read at the Annual Meeting of the Ent. Soc. Ont.

The earliest species which I noted during the past season, was the common and obnoxious currant saw-fly, Nematus ventricosus, which appeared on 15th May. Two days later I captured upon willow in bloom a specimen of Dolerus collaris, and on the 21st and 22nd found D. aprilis quite common on and about alders, with a few D. sericeus? and D. abdominalis. By the 24th May the strawberry saw-fly, Emphytus maculatus, and the raspberry saw-fly, Selandria rubi, were in considerable numbers, and at the same time appeared several less well known species in fields and woods, such as Hylotoma McCleayi. This species I found again on 2nd June and subsequent days, upon the flowers of choke-cherry. Later in the season specimens were found upon Spiræa. Selandria flavipes was captured on 10th June, and was abundant during the season. It could always be obtained by using a sweeping-net among the common fern. At the same time could be obtained in abundance upon the ferns greenish larvae which I have no doubt were those of that species.
