punctulate ; the former black ; the oral parts piceous or rufo- 

 piceous, the left mandible large and prominent ; thorax consider- 

 ably convex, narrowish, not broader than the widest part of the 

 elytra, the hinder and lateral margins nearly forming a semi- 

 circle; the fore angles in a smaller arch; sometimes piceous; the 

 lateral and hinder margin rufo-brunneous, which tint is broadest 

 at the posterior angles ; sometimes also the fore-margin is narrowly 

 of this hue; scutellum triangulate, smooth, of considerable size; 

 the elytra very convex, somewhat gibbous, in breadth nearly in 

 proportion with the thorax; truncate obliquely at the shoulders; 

 slightly narrowed behind; the suture prominent; very thickly 

 and distinctly punctate; no sutural stria; either entirely black, 

 or, with the apex, and the suture, particularly posteriorly, 

 brunneous; legs rufous. 



Occasionally under bark of trees, but more frequently among 

 moss, or beneath stones and rubbish; Carr's Hill, Ravensworth, 

 North Sunderland, Hartlepool. In Scotland, it has occurred in 

 Berwickshire and Aberdeenshire. — J. H.
