The ^^^-11^- wings are of a deep, rich, reddish, velvety brown, with a dark streak about the middle of the fore wings, extending from the body half-way !1\X*^^^^^^ across, and on this is a g;olden spot; there are also two golden spots near the apex of the wing. When the wings are spread they measure nearly an inch and a half across. In the larval state this insect is preyed on by a small Ich- neumon fly, and, never being abundant, other remedies are not needed to subdue it. No. 50.—The Apple-leaf Miner. Tischeria malifoliella Clemens. The larva of this insect lives within the leaf of the apple- tree, between the upper and the under skin, devouring the soft tissues, and burrowing an irregular channel, which begins as a slender white line, dilating as the larva increases in size, and ultimately becoming an irregular brownish patch, sometimes extending to, or over, the place of beginning. The caterpillar is of a pale-green color, with a brown head, and the next seg- ment brownish. When about to change to a pupa, the leaf is drawn into a fold, which is carpeted with silk, and in this enclosure the chrysalis is formed, the change occurring during September. When the leaf falls, its occupant falls with it, and remains on the ground within the folded leaf until the following May.
