Habitat: "In Indiis" (Fabr.).
Head small, and margined in front; being furnished with a single horn that bends towards the thorax. Thorax margined, and dark brown (the general colour of the insect); being armed with three remarkable horns, whereof two are placed in front, one on each side; being very strong and broad one way, but thin the other, and branched at their extremities. The other horn is placed on the hinder part of the thorax, being short and thick at bottom, but sharp and pointed at top; springing from a protuberance that almost covers the escutcheon, which is small and triangular. All these horns are immoveable, and their situations occasion a most remarkable hollowness or cavity in the thorax, which is smooth and shining; but the protuberance, next the scutellum, is full of punctures, and the edge notched. Elytra shining, punctured, and slightly striated. Abdomen and legs red brown, and hairy; the hinder ones being remarkably thick and strong, with two broad tibial spurs. The middle and fore tibiæ are strongly dentated, each being furnished with a thick spur. Anterior tibiæ with the first joint long and slender, but in the middle and hinder tibiæ, exceeding thick and strong.
