Antennas moderately stout, thickened towards the 

 apex, pitchy in colour, paler at the base ; joint two 

 slightly longer than three, four to ten each slightly broader 

 than its predecessor, four about as long as broad, five a lit- 

 tle transverse, the following ones gradually more distinctly 

 so; eleventh joint nearly as long as the two preceding 

 together. The head is rather small, narrower than the 

 thorax, much narrower than the elytra, black and shining, 

 finely and indistinctly punctured. Thorax narrower than 

 the elytra, a third broader than long, rather narrower at 

 the anterior than at the posterior angles, its punctuation 

 neither fine nor close ; in front of the scutellum is a broad 

 obsolete impression, sometimes appearing double. The 

 elytra are about a third longer than the thorax, of a 

 brownish or blackish colour, densely and rather strongly 

 punctured and pubescent. The abdomen is black and 

 shining, segments two to four distinctly but not densely 

 punctured, five and six nearly impunctate. Legs red- 

 dish-yellow. 



The male has the hind margin of the upper plate of 

 the seventh abdominal segment distinctly excised, the 

 margin of the excision is scarcely visibly thickened ; the 

 ventral plate of the same segment is very narrow towards 

 the apex, but the apex itself is not pointed. 



Not uncommon in fungi in the summer. Abundant 

 near Edinburgh. 



Ohs. — This species varies in the colour of its antennee 

 and elytra. It is not very closely allied to any of our 

 other species, but H. hnmeralis, Kr., found in Germany 

 and Sweden, is very near it.
