168 Dr. Sharp's Revision of the 



broad, five considerably broader than four, five to ten 

 transverse ; eleventh joint rather short. Head large, but 

 little narrower than the thorax, a little rounded behind 

 the eyes, which are large and rather prominent, dull, 

 closely and distinctly though not deeply punctured. 

 Thorax a little narrower than the elyti-a, about a fourth 

 broader than long, a little narrowed in front, and slightly 

 more so towards the base, with an indistinct longitudinal 

 channel along the middle, dull, obsoletely but closely 

 punctured. Elytra of a lurid brownish colour, fully one- 

 third longer than the thorax, densely but extremely finely 

 punctured. Abdomen black (sometimes with the ex- 

 tremity pale), segments two and three finely and not 

 densely punctured, four rather more sparingly punctured, 

 five and six almost impunctate. Thighs pitchy, tibias and 

 tarsi testaceous. 



In the male, the sixth segment of the abdomen is fur- 

 nished, on the upper side in the middle, before the pos- 

 terior margin, with a small raised tubercle ; the seventh 

 segment has two raised longitudinal lines on its surface, 

 the space between which is rather depressed, especially 

 just before the hind margin, and the lines project a little 

 beyond the margin in the form of two small indistinct 

 teeth. 



Rather common in England, under the bark of dead 

 elm trees. 



Ohs. — This species may be distinguished from all 

 others by its distinctly and thickly punctured head, 

 taken in conjunction with its flat broad form, and dull 

 appearance.
