62 COLEOPTERA. 



and is merged in the aliitaceous space hereafter mentioned ; 

 each of these lateral foveolae is also connected on its inner 

 side by an oblique, narrow and obsolete channel, with the 

 dorsal fovea nearest to it ; the thorax is delicately margined, 

 the margins rather strongest and a little reflected at the sides, 

 and there is a narrow space parallel to and almost touching 

 the base, but not quite reaching the posterior angles, free 

 from punctures, and a little elevated ; the raised part of the 

 disc terminates rather suddenly and obliquely at the hinder 

 angles, leaving a flat, alutaceous space, enclosed by the mar- 

 gins of each posterior angle, and bearing the faintest possible 

 trace of punctuation. 



The scutellum is alutaceous. 



The elytra are more than twice the length of the thorax, 

 with their sides straight, but getting slightly wider until 

 about the middle of their lower third, thence obliquely sloped 

 to the posterior margin, the angles being rounded; rather 

 thickly and coarsely punctured, the punctuation being con- 

 fluent, whereby irregular, longitudinal, rngulose and shining 

 elevations are formed, which are somewhat finer towards the 

 apex; delicately margined, the sides strongly deflexed; the 

 suture is shining, and but little elevated. 



The abdomen is alutaceous, and very indistinctly punctured, 

 rather convex in the middle, and strongly margined at the 

 sides. 



I have long had a single specimen (which is certainly 

 quite mature and symmetrical) of this distinct species, un- 

 named in my collection ; it was taken by myself in the Lon- 

 don district, but I cannot, unfortunately, specify any more 

 exact locality.
