Head green and nearly square; the surface irregular and uneven. The corners are pointed, forming two black obtuse angles. From the front of the head issues a small black and thick protuberance, like a horn, that divides into two branches, each of which terminates in a sharp point. All the remaining parts, except the tarsi, are of a fine lively green, differing in shades according to the manner in which it is held to the light; and appearing to be so highly polished, that the colour seems reflected from a part beneath the surface. Scutellum large and triangular. Sternum small. Abdominal scales small and close. The fore legs are very long and slender, the tibiæ being dentated. Elytra having two small swellings near their extremities, and furnished at the suture with two short thick spines; the anus extending beyond them. Anterior tarsi having a small tuft of brown hair placed on the last joints, next the ungues. {63}HOPLIA COERULEA. Plate XXXII. fig. 4. ORDER: Coleoptera. SECTION: Lamellicornes.
