NEW BRITISH SPECIES, ETC., IN 1.864. 63 



obese and rather stout. The antennse are very short, tes- 

 taceous, with the club pitchy-black. The head and thorax 

 are very strongly and rather closely, and the elytra rather 

 closely and very deeply and coarsely, punctured ; the sutural 

 space is dark, and the suture itself blackish. 



It may be known from //. punctatusimuiiy it largest con- 

 gener, by being much larger, broader, flatter, lighter in 

 colour and more deeply punctured ; also by the seventh 

 joint of the antennae being pitchy black, instead of rufo- 

 testaceous.

 Mr. Crotch says he has about eight specimens of this and the 

 next species, collected in North Wales, Liverpool and Scot- 

 land, and has seen others in two or three Collections ; also 

 that he has sent his series to M. Thomson for his verdict on 

 the subject, as the two species seem to be closely allied. 



There are two specimens of H. punctatus (I beheve) in 

 Dr. Power's Collection; and Mr. F. Archer, jun., has re- 

 corded the capture of a specimen, in the month of September, 

 by sweeping, close to Hightoun, near Liverpool (Zool. 8973, 

 1864). 



From Thomson's description (loc. cit.) H. punctatus 

 appears to be larger than H. spimpes, with the elytra more 

 strongly punctate-striate, the interstices scarcely rugulose, but 

 with series of deep punctures, and the body light-coloured.
