This species, though narrower and more parallel than 

 its allies, is pretty near to H. trinotata and triangulum. 

 The antennae are moderately long and stout, very little 

 thickened towards the apex, the basal joint yellow, and 

 the two or three following ones more or less distinctly 

 so, the rest pitchy ; joints two and three of nearly the 

 same length, four small, about as long as broad, five 

 broader than four, five to ten differing but little from 

 one another, transverse but not strongly so, the last 

 joint moderately long and stout, about as long as the 

 two preceding together. The head is a little narrower 

 than the thorax, rounded behind the eyes, finely and in- 

 distinctly punctured. The thorax is but slightly narrower 

 than the elytra, a third or fourth broader than long, the 

 sides a little rounded at the anterior angles, then nearly 

 straight and scarcely narrowed behind, finely and not 

 closely punctured, with a very obsolete impression in 

 front of the scutellum, and sometimes with a fine indis- 

 tinct channel. The elytra are about a third longer than 

 the thorax, yellow, with three tolerably distinct darker 

 triangular patches, one at the scutellum, and one on each 

 side near the outer angle ; finely and pretty closely 

 punctured. The abdomen is black and shining, seg- 

 ments two to four rather sparingly punctured, fifth very 

 sparingly punctured, sixth nearly impunctate. Legs 

 yellow. 



In the male, the dorsal plate of the seventh abdominal 

 segment has the apex truncate and crenulate ; the ventral 

 plate of the same segment has also the posterior margin 

 more rounded than in the female. 



Generally distributed in England, and in the south of 

 Scotland, but rare. 



Ohs. — This species in colour bears a resemblance to 

 H. ceneicollis, but is smaller and narrower, and has shorter- 

 jointed antennae.
