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 {59}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.
