To the Members of the Entomological Society of Ontario.

Gentlemen,—While Entomology may be said to deal with small things, the abundance or scarcity of the tiny creatures called insects involves great issues. The truth of this statement has been illustrated forcibly in several directions this year, notably in the case of the Angoumois wheat moth, which has played sad havoc among the stores of corn and wheat in granaries in the South-western States.

Not long since I received a letter from a correspondent in Europe, asking what my experience was in regard to the life of butterflies, and this led to much thinking of the matter and reference to my note books, in which for more than fifteen years I have put down everything that has come under my observation relating to butterflies.

On Saturday morning the Entomological Sub-section was again in session, when the following papers were read :

The Egg Case of Hydrophilus triangularis, by C. V. Riley; on the Oviposition of Prodoxus decipiens, and also one on the Cocoon of Gyrinus by the same author. Following these a paper was presented by B. P. Mann, entitled, Suggestions of Co-operation in Furthering the Study of Entomology; and another by C. V. Riley, on New Insects Injurious to American Agriculture.
