This insect, which is represented magnified in Fig. 153, is about one-fifth of an inch long, and varies in color from dull dark brown to a p-reenish or dirty „ yellowish brown, the males bemg gener- ally darker than the females. The head is yellowish, with three narrow, reddish stripes ; the beak or sucker is about one- third the length of the body, and when not in use is folded upon the breast. The thorax has a yellow margin and several yellowish lines running lengthwise; behind the thorax is a yellow V-like mark, some- times more or less indistinct. The wings are dusky brown, and the legs dull yellow. It passes the winter in the perfect state, taking shelter among rubbish, or in other convenient hiding-places, and early in May, as soon as vegetation starts, it begins its dep- redations. Concealing itself within the young leaves of the expanding buds of the pear, it punctures them about their base and along their edges, extracting their juices with its beak. The puncture of the insect seems to have a poisonous effect, and the result is to disfigure and sometimes entirely destroy the young leaves, causing them to blacken and wither. These insects are also partial to the unopened buds, piercing them from the outside, and sucking them nearly dry, when they also become withered and blackened. Sometimes a whole branch will be thus affected, being first stunted, then withering, and finally dying. Early in the morning these plant-bugs are in a sluggish condition, and may be found buried in the expanding leaves, but as the day advances and the temperature rises they become active, and when ap-.
