Third stage.—The third stage differs from the second principally inthe larger size of the body, which has assumed a pyriform shape, thedarker color of the body and bands on the legs, and in the greaterprominence of the tubercles at the sides of the body. The three tho-racic segments are also more prominent, prolonged posteriorly, andoverlapping at the sides. Its sides are reflexed, strongly dentate

Length, about stage is not illustrated. Fourth stage (fig. 6,/).—With this stage, as in tristis, the wing-padsbecome evident, the thorax widens, the abdomen increases in girth, andthe third joint of the antenme decreases in width. The reflexion anddenticulation is still more pronounced. Length, about 7miu. Fifth stage (fig. 6, g).—In the fifth or last stage this species moreclosely resembles the mature form than is the case with tristis. This.

THE HORNED SQUASH BUG. 33 effect is produced by the prominent angle of the prothorax and thesimilar markings of the legs. In addition to the increased length ofthe wing-pads and other observable characters, shown in the illustra-tion, the spines in front of the head which have now made their appear-ance are noticeable. The central portion of the abdominal tubercles areyellow, and yellow alternates with black on the lateral tubercles of theabdomen. The entire body, including the ventral surface, is darker incolor. The last antennal joint is black, at leas
