the base more or less testaceous. Thorax subcordate, longer 

 and more quadrate than in ustulatum (PL II. f. 9), the sides 

 rounded and rather dilated about the middle, very gradually 

 narrowed behind till a. little before the angles, then straight, so 

 as to form with the posterior margin right angles, with the apex 

 a little prominent', the disk very much wrinkled, the dorsal 

 furrow strongly impressed and the anterior impression which 

 meets it well defined, base with a deep fovea on each side, the 

 space between which is depressed and very much striated longi- 

 tudinally. Elytra oblong-ovate, shoulders distinctly rounded, 

 much wider than the thorax, sides only slightly rounded, a little 

 narrowed at the apex, very strongly striated, especially near the 

 suture in front, the strise distinctly punctured till behind the 

 middle when the punctures disappear and the striaB become 

 smooth and less deep from thence to the extremity, between the 

 second and third striae are two deep impressions and a few 

 distinct punctures on the outer margin near the shoulders, the 

 colour is usually brassy brown, more or less dark, and there is 

 always a testaceous zigzag or wavy band extending transversely 

 from the outer margin to the suture at no great distance from 

 the apex, and a very obscure or obsolete one before the middle, 

 which, in immature examples, extends over the surface of the 

 anterior portion of the wing-cases; the apex of the abdomen 

 testaceous, legs pitchy testaceous, with a greenish metallic hue 

 on the upper side of the femora. Length 2-2f lines. 



Extremely abundant on the banks of rivers, in damp woods 

 and marshes throughout the kingdom.
