British Species of Homalota. 125 



broad as the elytra, its length about equal to it breadth, 

 scarcely visibly narrowed behind, finely but not densely 

 punctured, with an indistinct impression in front of the 

 scutellum, from which proceeds a short channel, varying 

 in distinctness, and sometimes absent. Elytra pitchy- 

 black, not longer than, or scarcely so long as, the thorax, 

 finely and pretty densely punctured. Segments two to 

 four of the abdomen are finely, evenly, and densely punc- 

 tured ; the punctuation of the fifth and sixth segments 

 is more sparing, but distinct ; the extremity of the abdo- 

 men is obscurely paler. The legs are pitchy- testaceous. 



In the male, the ventral plate of the seventh segment 

 of the abdomen is narrower than in the female, and pro- 

 jects considerably beyond the upper plate ; its hind mar- 

 gin is flattened, and sometimes appears emarginate in 

 the middle. 



This species can only be confounded with H. elonga- 

 tula, but it is a little larger, darker, and more shining ; 

 the elytra are shorter, and the punctuation of the abdo- 

 men is throughout denser and more even than in H. 

 elongatula. 



Found hitherto only on the higher mountains of Scot- 

 land, Ben Lomond, Mamsoul, &c.

This species is readily distinguished by its deep black 

 colour, its rather narrow elongate form, and its short 

 elytra, only the length of the thorax. The antennae are 

 pitchy, or pitchy-black, with the basal joint obscurely 

 paler ; they are a little thickened towards the apex ; 

 joints two and three of about equal length ; four and five 

 each about as long as broad, the fourth smaller than the
