Similar to the foregoing, but differs in the form of its thorax, and slightly in 

 punctation : head strongly punctate, with the nape and a central anterior 

 patch nearly smooth : thorax quadrate, very coarsely punctate ; the disc a 

 little convex, the dorsal line nearly obsolete, and the hinder angles with a 

 mere rudiment of fovese, but very thickly punctate : elytra rather flat, faintly 

 striated, the interstices punctate throughout ; the marginal one with an inter- 

 rupted series of impressions : body strongly and thickly punctate beneath : 

 legs, antennae, and palpi rufo-testaceous. 



Var. j3. With the abdominal segments rufescent on the margins. 



Not sufficiently distinct from the foregoing ; the chief distinction consisting in 

 the form of the thorax, and the more profound punctation: Duftschmid 

 expunges it from the Austrian Fauna. 



Taken occasionally near London, in Southend. " One specimen 

 at Winterbourne, Stoke, Wilts, in April." — Rev. G. T. Rudd.
