Report on the Rocky Mountain locust and other insects now injuring or likely to injure field and garden crops in the western states and territories . heir growth in fromsegment, enlarged; c, d, e, f, q, markings; /j, three tO four weeks. When cocoon; i, male moth.—(After Riley.) about to transform they for- sake the fruit in which they had burrowed, and drawing together portionsof some leaf that lies ou or near the ground, spin a slight cocoon of whitesilk. Within this cocoon they soon become slender, brown chrysalides,with the head parts prolonged, and with a very long ventral sheathwhich incloses the legs. If it is not too late in the season the moths issuein from eight to ten days afterward. The late individuals, however, passthe winter within their cocoons; though from the fact that some mothscome out as late as November, I infer that they may also winter overin the moth stiite. (Riley.) The m-oth is yellowish-browu, with golden,yellow spots on the fore wings, and the hind wings yellow, with a broad,dark border.
