Short, black : clypeus with three tubercles, the middle one subcornute, and an 

 anterior bent carina : thorax convex, deeply punctulated, glossy : elytra rather 

 obscure, fuscous, with the suture black, punctate-striated, the interstices 

 punctulated ; legs black. 



This may possibly be a large variety of the foregoing species ; from which it 

 chiefly differs in bulk, in the paler hue of its elytra, and by having the 

 central tubercle of the clypeus considerably produced. 



Not uncommon near London. " Bottisham." — Rev. L. Jenyns.

 thorax thickly and somewhat finely punctulated : elytra brunneous or red-

 uncommon (near Swansea).'" — L. W. Dillwyn, Esq. " Bottisham."
