 Head black, smooth and shining, less wide than in the preceding 

 species and less produced in front. Thorax after the same 

 manner. Elytra narrower, finely striated, the striae obsoletely

This species is extremely abundant in the fens of Cambridge- 

 shire and Huntingdonshire both in spring and autumn, among 

 sedge and at the roots of herbage. I have found it also at 

 the roots of the tall wiry grass which grows on the sand-hills 

 at Sandwich, Kent. Mr. Stephens informs us that it is found 

 at Swansea and at South Creek, Norfolk.
