British Species of Homalota. 153 



Thorax a little narrower than the elytra^ nearly as long 

 as broad, somewhat narrowed behind, quite dull, with 

 a broad central longitudinal impression in the middle, 

 with a fine channel, sometimes very indistinct ; sculpture 

 indistinct. The elytra are brownish, a little longer than 

 the thorax, and not quite so dull as it, punctuation fine 

 and dense. The abdomen is black, shining towards the 

 apex, the posterior edges of the segments obscurely 

 brown ; segments two to four closely and distinctly 

 punctured, fifth more sparingly punctured, sixth almost 

 impunctate. Legs yellow, posterior tarsi moderately 

 long. 



In the male, the front of the head has a distinct broad 

 impression, and the longitudinal impression on the thorax 

 is more distinct than in the female ; the fifth segment of 

 the abdomen has, on the upper side, two small raised 

 granulations ; the sixth segment has two transverse 

 rows of short raised longitudinal lines, four in each 

 row; those in the hind row closer to one another than 

 those in the front row. The sixth segment has the pos- 

 terior margin furnished with four small sharp projecting 

 teeth, the outside ones being indistinct. 



Not common ; found in the bark of oak stumps in 

 England. 



Ohs. — This species cannot easily be mistaken for any 

 other, if the very dull head and thorax, the brownish 

 elytra, and the yellow legs, be noted.
