Head rather square, depressed above; dusky in front, grey behind. Eyes round and prominent. Antennæ black. The thorax dusky green, margined. Scutellum large, triangular, and green. Elytra dusky green, the sides and suture margined, having two swellings near the extremities, and two short thick spines at the end of the suture. The abdomen covered above with a fine brown pile like velvet. Hind part of the abdomen green, with two silvery white spots of a squarish form. All the under side of the insect green, and of a more lively or shining colour than the upper. Legs strong and thick, the tibiæ furnished with thick spines, both in the middle and at the tips, the hinder ones being hairy.
This splendid and exceedingly rare insect flew on board a ship at Sierra Leone, and was taken on the awning on the following morning. It seems to be unknown to the French Entomologists, and is omitted in the "Monographie des Cétoines" of Messrs. Gory and Perchéron.
