The head is hollowed out on the top, the under side of the body smooth, and the legs short and stout. It conceals itself during the day, but is active at night, feeding upon the sap which flows from the bark. Since the larva feeds chiefly on decaying wood, the injury inflicted, if any, can only be of a trifling ATTACKING THE BRANCHES. Fig No. 9.—The Woolly-louse of the Apple. Schizoneura lanigera (Hausm.). This is the same species as the apple-root plant-louse (No, 1),Out in this form the insects attack the trunk and limbs of theapple-tree, living in clusters, and secreting over themselvessmall patches of a cotton-like covering. (See Fig. 13, wherethe insects are represented magnified.)They are often found about the baseof twigs or suckers springing fromthe trunk, and also about the base ofthe trunk itself, and around recentwounds in the bark. In autumn theycommonly affect the axils of the leaf-stalks (Fig. 13), towards the ends oftwigs, and sometimes multiply to suchan extent as to cover the whole un-der surface of the limbs and also ofthe trunk, the tree looking as thoughwhitewashed. They are said to affect most those trees which
