HEMIPTERA This order contains some of our most common and destruc- tive insects, as the chinch-bug, the grape phyllox'cra, the San Jos^ scale, the bed-bug (Fig. Ill), the louse, the squash hug, stink-bugs of various kinds, plant-lice {Aphid'id(r), and bark-lice iCoc'cidw), which furnish dyo-stuft's, as cochineal, stick-lac, from which we get shellac, and China wax. The Hemip'tera include some five thousand species in North America. All of these species agree in that the mouth parts arc modified into a piercing and sucking beak. Their food, con- sequently, is the blood of men or of other animals or the juices.
