Above brassy black, sometimes greenish black, shining; 

 antenna pitchy black, with the base testaceous. Thorax trans- 

 verse, rounded at the sides, not strictly speaking narrowed be- 

 hind, but so rounded as to give it in a great measure that 

 appearance, the posterior margin distinctly emarginate behind 

 the angles which are somewhat rounded (PL II. f. 7), disk 

 moderately convex, the dorsal furrow intersected by numerous 

 fine transverse wrinkles and terminated before and behind in 

 distinct impressions, the anterior one minutely strigose, the 

 posterior one more distinct and somewhat rugose, the base also 

 with an oblique deeply impressed fovea on each side. Elytra 

 oblong-ovate, deeply striated near the suture, less deeply on the 

 sides, all the strise punctured, but the apex smooth, and with a 

 round testaceous red spot near the outer margin more or less 

 distinct; underside black, legs reddish testaceous. Length 

 2 lines. 



This species may be distinguished from both teneum and 

 guttula, by the more rotundate hinder part of the thorax, though 

 some examples scarcely exceed the latter in size. It varies also 

 in depth of colour ; some examples have a more decided greenish 

 tinge, and purplish varieties occasionally occur. 



It is generally distributed and abundant.
