Upon illuminated buildings, especially upon shop windows, they fluttered and crawled in myraids, and they dashed into every open window or doorway. The plague lasted for some days, during which an immense number perished in the arc- lamps and in other ways. The tent caterpillars are among those insects but little affected by climatic changes. The clusters of eggs (Fig. 19, c.) encircling the twigs are protected by a waterproof varnish-like secretion, and the caterpillars as soon as hatched proceed to spin the web which serves to protect the colony against the weather's vicissi- tudes, and to some extent from various enemies. Their parasitic enemies, however, are numerous and watchful and find opportunities to infest many of the caterpillars, so that the increase of the species is checked and eventually stopped, and an unusual abundance one year may be followed the next season by a comparative scarcity. Dr. Bethune, the Director for Division No. 2, was next called upon to report; NOTES ON THE SEASON OF 1897. By the Rev. C. J. S. Bethune, Port Hope. Collectors of insects throughout the Provinces of Ontario and Quebec have, with few exceptions, pronounced the season of 1897 an " oflyear " as far as the capoure of speci- mens was concerned. The scarcity of many common species may no doubt be largely attributed to the character of the preceding winter, which was remarkable for its sudden changes from mild weather to extreme cold and the frequent thaws which occurred. These great and rapid alternations of temperature are usually very fatal to any insects "whose winter quarters are ,exposed or near the surface of the ground. But not only was the winter a trying one for insect life, the spring was for the most part cold and wet, and summer, coming very late, brought little fine or hot weather ; with the exception of some ten da
