The males are not much more than half the size of the females; the former, when their wings are expanded, measure about an inch and a half across, the latter nearly two and a half inches. Like that last described, this is a rare insect, and one never likely to appear in sufficient numbers to be troublesome. No. 35.—The Oblique-banded Leaf-roller. Cacoecia rosaceana (Harris). This moth is a member of a very large family of small moths called Tortrices, or, popularly, leaf-rollers, because their larvae have the habit of rolling up the leaves, or por- tions of them, forming hollow cylinders, firmly fastened with silken threads, in which they live, and where they are partly protected from birds and other enemies. Most of these insects, when disturbed, slip quickly out of their enclosure and let themselves down to the ground by a fine silken thread, and thus frequently escape danger. • Soon after the buds of the apple-tree begin to open, the caterpillars of the oblique-banded leaf-roller commence their labors. They coil up and fasten together the small and tender leaves, which thus furnish them at once with shelter and food. When full grown, they are about three-quarters of an inch in length, of a pale-green or yellowish-green color, sometimes reddish or brownish, with the head and top of the first seg- ment brown ; there is usually a darker green stripe along the back, and a few smooth dots on each segment, from each of which there arises a short, fine hair.
