as if from the large punctures having pierced through the 

 edge and left circular breaks in its continuity. This raised 

 margin is distinct and well marked on the sides, and extends 

 along the base, but is wanting in front. The basal raised 

 margin is virescent ; there is the trace of a dorsal smooth 

 ridge most distinct in front. The scutellum is dull metallic 

 red, with virescent margins ; it is triangular, with the apex 

 rounded, and is distinctly punctate, though not so coarsely or 

 deeply as the head and thorax ; a faint irregular impunctate 

 raised line passes down the middle. The elytra are smoother, 

 particularly on the disk ; but are so closely covered with minute 

 punctures as to have something of an opaque appearance. Be- 

 sides these minute punctures, there are others of various larger 

 sizes scattered among them ; and a third class of still larger 

 punctures is also to be seen, which have a tendency to run in 

 striae. The whole of these punctures, however, are very shallow, 

 and have no resemblance to the deep punctures on the head 

 and thorax. They are most deeply impressed about the base 

 of the elytra. The disk is flattish, the shoulders are promi- 

 nent, and a sort of ridge connects them with an apicul promi- 

 nence, the sides falling rapidly down on each side, and ex- 

 panding somewhat behind ; the wings are long and brownish. 

 Pygidium finely punctate — most closely and finely at base. 

 The under side is of the same colour as the upper ; the abdo- 

 men and thighs are smoother and more shining. Prosternum, 

 and especially mesosternum, clothed with longish fulvous pu- 

 bescence ; mesosternum coarsely punctate ; segments of abdo- 

 men more faintly and sparingly punctate ; punctures deepest 

 along the margin of the segment ; legs coppery, dark reddish 

 brown, with faint metallic lustre ; anterior tibiae with three 

 teeth ; tarsa moderate in length, and slightly thickened. In 

 the only specimen I have received the middle tarsi have the 

 outer claw bifid, and the posterior tarsi the claws simple ; — 

 the anterior claws have been broken off.
