Recently, while studying the habits of this beetle in the peach orchards of Catawba Island, on the south shore of Lake Erie, I was surprised to observe that the fall attack had invariably been made on the east or southeast side—which is here the land side of the trees—and old trees, where the bark of the trunks was very rough, were more seriously affected. On mentioning the fact of this apparent discrimination in point of attack to my friend Dr. D. S. Kellicott, he recalled that the same phenomenon occured about Buffalo, New York.
