126" Dr. Sharp's Revision of the 



fifth ; the following joints differ but Kttle in length, each 

 is a little broader than its predecessor ; the penultimate 

 joints each a little broader than long ; the eleventh joint 

 is rather stout, about half as long again as the tenth. 

 The head is a little narrower than the thorax j the disc 

 flattened, and somewhat depressed in the male ; in the 

 female convex and with a small fovea, sparingly and 

 indistinctly punctured. The thorax is about as broad 

 as the elytra, about a fourth broader than long ; the sides 

 nearly straight, very slightly narrowed behind, very finely 

 and not closely punctured, moderately shiuing, with an 

 indistinct impression in front of the scutellum. The 

 elytra are about as long as the thorax, black or pitchy- 

 black, rather sparingly punctured, but more distinctly 

 than the thorax, pubescence fine and scanty. The abdo- 

 men is black and shining, segments two to four sparingly 

 punctured, fifth still more sparingly punctured, sixth 

 nearly impunctate. Legs pitchy, or pitchy-yellow, tarsi 

 rather stout. 



In the male, the under plate of the seventh segment 

 of the abdomen is considerably produced and narrowed 

 towards the apex ; iu the female, the apex of this plate 

 is broad, not produced, a little emarginate in the middle, 

 and furnished with short parallel black cilia. 



Common on the hills of Scotland, Wales, and the 

 north of England. 



Obs. — It is remarkable that no one of the three species 

 restricted in this country to the hills (viz., tibialis, ere- 

 mita, and clavipes,) appears to have yet been found in 

 Sweden.
