Insects injurious to fruits . smaller ones onthe thorax. The scutel, which is at thepoint of junction of the wing-cases withthe thorax, is yellowish. The beetle issaid to be more active at night than inthe day, and seems to show a preferencecv for the tender, succulent shoots of theapple, although it makes quite free withthose of the peach, pear, plum, andcherry. Sometimes it occurs in swarmsin nurseries, when it seriously injures theyoung trees. In the East it is seldompresent in sufficient numbers to proveinjurious, but it is very common in the valley of the Missis-sippi. The larva is found in the twigs and tender branchesof the bur-oak, and probably also in those of the pig-nuthickory. When the female is about to deposit an egg, she makes alongitudinal excavation with her jaws, as shown at a in , eating upwards under the bark, and afterwards turnsround and places an egg in the opening. The larva (6 in the figure) is a soft, footless grub, of apale-yellow color, with a tawny head; it is not known whether. ATTACKING THE LEAVES. 197 it undergoes its transformations within the twig, or enters theground to pass the pupa state. Remedies.—There seems to be none other than to catch andkill this mischief-maker. In common with almost all othercurculios, this beetle has the habit of falling to the groundwhen alarmed, and hence may be captured by jarring thetrees in the manner directed for the plum curculio, No. 94. ATTAOZING THE LEAVES. No. 101.—The Peaeh-tree Leaf-roller. Ptycholomapersicana (Fitch). Early in spring, when the young leaves are expanding, asmall worm sometimes attacks them, and, drawing them to-gether with fine silken threads, secretes itself within, andfeeds upon them. This larva is rather slender, of a pale-green color, with a pale, dull-yellowish head, and a whitishstreak along each side of its back. When full grown, itchanges to a chrysalis within its nest, where it remains abouttwo weeks, and then escapes as a moth. The fore wings of the moth
