32 COLEOPTERA 



united in front by a transverse line, the forehead is more or less rugu- 

 lose, but the vertex is smooth. Protlwrax convex, margined, base and 

 apex somewhat emarginate ; it is rather broader than long, with rounded 

 sides, sinuated behind, and rectangular posterior angles ; its dorsal line 

 is not very distinct, and does not reach the base and apex, there is an 

 ill-defined frontal impression, the base is a little depressed, with two 

 large and deep foveae, and the rest of the surface is almost smooth. 

 Scutellum triangular, its base impressed with longitudinal lines. Elytra 

 transversely convex, rather broad, a little narrowed in front, sinuated 

 and narrowed towards the apex, with acute humeral angles ; each bears 

 a short scutellar, and seven discoidal, finely punctured striae, the sutural 

 feebly impressed ; the interstices are somewhat convex, especially near 

 the sides and apex ; there are four punctures and an apical transverse 

 impression on the third, a similar mark behind on the sixth, six punc- 

 tures near the eighth stria, and a row near the margin, the marginal 

 channel being more or less rugose and interrupted, particularly near the 

 extremity, and the sculpture near the apex is somewhat irregular. Palpi 

 stout. Thighs rather strongly inflated and almost dentate below. The 

 lower part of the body shining black. 

 Length, 12 lines ; breadth, 4f lines. 



This is the finest and most robust species of the group known to me. 

 The above description has been taken from a specimen which I received 

 from Mr. C. M. Wakefield.

 ZooL, 1841, /. i2i.j Obscure bronze-colour above, black beneath; 

 head smooth, with two feeble impressions in front between the antennae ; 

 palpi elongated, with the last joint quite cylindrical and somewhat 

 obliquely truncated at the end ; antenna with four first joints smooth 

 and black, the others hairy and brownish towards the end ; thorax

 and somewhat sinuated behind ; very slightly notched on the hind 

 margin, with a longitudinal groove in the middle and a large fossa on 

 each side behind ; scutellum triangular, much wider than long, with 

 longitudinal wrinkles at the base; elytra rather wider than the thorax; 

 at their base slightly widened; rounded on the sides towards the middle, 

 very feebly sinuated towards the end ; each has nine punctured striae, 

 the spaces between considerably raised ; two or three large impressed 

 points between the second and third, fourth and fifth and sixth and 

 seventh striae'; eighth and ninth are not distinct, and furnished with 

 large, deep points, which end at the outer border ; beneath smooth :

 copied from White's work (Voy. Er. Terr. Ins., p. 3).
