Schf. This insect, like that last described, belongs to the order of true bugs (Hemiptera); it is commonly known as the red- bug, or cotton-stainer, and is one of the worst pests with which the cotton-planters of Florida and the West Indies have to contend. It injures the cotton by piercing the stems and bolls and sucking the sap; but the principal injury to the crop is occasioned by its staining the cotton in the opening bolls with its excrement. It also attacks the fruit of the orange, puncturing the rind, sucking the juice, and causing the fruit to decay and fall to the ground. When full grown, it is from six to seven tenths of an inch long, and appears as shown in Fig. 397, the thorax triangular, with its anterior part red, posterior por- Tig. 397. tion black, all margined with whitish yellow. The scutellum is triangular, red, margined with pale yellow; the wing-cases are flat, with two distinct whitish lines crossing them, which intersect each other near the centre; they are also partly margined with a yel- lowish line. The under side is bright red, with yellowish- white markings on the edge of each segment. Each female produces about one hundred oval, amber- colored eggs, which are attached in clusters to the under side of the leaves. The young bugs are bright red, with black legs and antennae. These bugs are usually found in immense numbers, and where cotton has been planted between the rows of orange-trees instances are recorded where a large propor- tion of the oranges have been destroyed.
