O. picipes is a dark brown insect, with yellowish scales. It is somewhat smaller than the first - named and exhibits not quite such diversified tastes. On Vines, Raspberries, and many outdoor fruits it is found alike as a perfect insect . y«<-, and a grub. O. tenebricosus is commonly know^n as the Apricot Weevil, but, like the other species named, it also lays several other plants under contribution— Nectarines, Plums, Peaches, and Rasp- berries. In size it is about ^in., black, covered with yellowish down. These three Beetles are all night feeders. They are very wary; so that the greatest care must be exercised to trap them. Sheets of tar-covered white paper should be laid down beneath the infested trees at dusk. As soon as it is dark the trees should be visited, and tapped. The Beetles will drop on to the sticky paper, from which they may be collected and destroyed. All holes in walls likely to afford shelter to the pests must be stopped up in winter. So far as the grubs are concerned, little can be done except to remove the soil to a depth of several inches, and char it, replacing with fresh. Anthonomus pomorum (Fig. 713) attacks both Apples and Pears : with the former, however, the insect is usually identified. The Beetles appear on the wing in early spring. They are about one fifth of an inch long, reddish-brown, with a somewhat irregular light band towards the base of the wing-cases. As will be seen in the illustration, there is the prolongation of the head into a beak-like organ. The females puncture the unexpanded flower- buds, and deposit therein an egg. The larvae, when hatched, feed upon the buds, causing them to prematurely fall. At this period the insects are
