clothed with grey pubescence ; tlie Lead is more deeply hollowed in 

 front, with a distinct middle elevation ; the elytra are much shorter, 

 not so convex, with the interstices not so flat or wide ; the abdomen is 

 more distinctly margined, with the middle keels more distinct. The 

 metasternum is depressed in the middle. In the male the sixth segment 

 has a triangular notch, and the fifth has a middle depression, widest, 

 and polished, towards the hinder margin, which is widely and rather 

 deeply emarginated in a somewhat semi-circular form ; on each side of 

 the emargination is an obsolete tubercular elevation. 



This species cannot be confounded with small examples of ^S*. 

 cemulus, Avith which it is sometimes found, on account of its dull 

 appearance, shorter elytra, and want of a dorsal channel to the thorax. 



First taken by Mr. E. "W. Janson at Finchley ; subsequently by 

 Messrs. Crotch, Matthews, Power, Brewer, and Sharp, at Wickeu and 

 Horning Eens. Both this and the next species are not satisfactorily 

 placed in this section, owing to their dark legs.

 any middle elevation. Thorax even. Elytra longer than the thorax, 

 evenly and strongly punctured, rather convex. Abdomen sub-cylin-
