Whetherthis is to be attributed to the extreme severity of the winter, or to the very dry summerwhich preceded it, we are unable to determine ; possibly both may have liad somethingto do with the result. Our usually common butterflies were seldom seen during thesummer, and those nocturnal visitors, the moths, as compared with the abundance ofaverage years, were few and far between. The same scarcity has been noted amongour insect pests—the plagues of the gardener and fruit-grower. Some, which haye beenabundant for many years past, were notably scarce, viz. : The Tent Caterpillar (Clisiocampa Americana), Harris. Fig- 7.
