culis, viriclibiis, crebre pimctatis (fortiter versus basin, levitcr 

 versus apiceni), alboque breviter setosis, apice recte trun- 

 catis et externe et ad suturam dcntatis • pectore cum abdo- 

 mine dense cinereo-villosis. 

 Long. 11-15 lin., lat. 3-4 lin. 



Opaque, black. Head keeled between the eyes, witli very 

 fine transverse folds behind. Palpi ferruginous. Antenna 

 longer and more slender tlian in tlie preceding species, ferru- 

 ginous, with the first article red and punctate, second and 

 third nodulated at the tip, fifth to tenth elongated, depressed, 

 somewhat dilated and angulated at the exterior tip, and ter- 

 minal article elongate and obliquely emarginate at the apex. 

 Thorax rather longer than broad, with transverse folds and 

 oblique channels from the base on each side of the disk, which 

 turn in and unite about the middle, and then proceed in the 

 dorsal line to the front, the whole producing a somewhat crown- 

 shaped discal island ; a strong tubercle on each side in front, 

 followed by a larger one in the middle, terminating in a rather 

 stout short spine. Scutellum triangular, without perceptible 

 punctures, but bearing a whitish velvety pile. Elytra broader 

 than the thorax, convex, rounded subrectangularly on the out- 

 side of the shoulder, parallel on the sides, becoming oblique 

 towards the apex, and truncated at the extremity, witli the 

 sutural and external angle sharp or toothed ; they are broadly 

 depressed at the base, bluish green, and, under the lens, very 

 closely punctured (the punctures of diftercnt sizes, and some- 

 times running into each other, forming rugose punctation) at 

 the base, and very finely and sparsely punctured towards the 

 apex, and from the punctures proceed a short silky pile. Legs 

 ferruginous, obscure at the knees. Breast and abdomen 

 brownish black, clothed witli a tolerably thick ashy pile. 



I have a variety of larger size, coarser punctation, much 

 larger and darker-coloured antenna;, elytra darker and not so 

 blue, longer pile on the underside, and darker legs, but with- 

 out any other distinction than an enlargement of all the 

 details. 



In describing this species, M. Chevrolat drew attention 1o 

 its resemblance to the nammaticlicras viridi2)e)iius of Hope, 

 but remarked that it differed by its smaller size and by its 

 elytra bjing convex instead of flattened. Specimens sub- 

 sequently received, more particularly the large variety above 

 mentioned, show that no distinction can be drawn from the 

 size ; Mr. Hope gives 12 lines as the size of his species, and 

 that of my specimens ranges from 10 to 15 : and the other 

 point of difterence, that the elytra are flattened, is founded on
