(H. Marklini, GylL, Zett. Long. 3 J ; larg. 2. Head testaceous, 

 ferruginous on sides and behind ; thorax testaceous, with anterior 

 and posterior margins broadly black ; elytra black, with broad irregular 

 griseous fascia across the base, into which run five or six abbreviated 

 longitudinal lines of same colour; sides of elytra griseous. Sweden.)

 It lust. Dr. Schaum retains with propriety the name of H. pubescens 

 for this species (although H. melanocephalus, Marsh., has the claim of 

 priority), in order to avoid confusion with H. melanocephalus, GylL, 

 Aube, a very distinct species, which has not yet received any other 

 name. Long. 3 J ; larg. If. 



25. H. melanocephalus, GylL, Aube. Long. 3| ; larg. 1-| — 2. 

 Black, punctulate, hardly shining; sides of thorax very slightly 

 rounded, continued in same line with sides of elytra; elytra rounded 

 towards the apex ; legs ferruginous, feet black ; body beneath black. 

 I took this species on the hills behind Oban, September, 1854, in

 out Great Britain. 



27. H. nigrita, Fab., GylL, Aube. H. trivialis, Steph. Long. 3 — 3j ; 

 larg. If — 1-|. This species is, by some accident, omitted in Schaum's 

 valuable list of our British species (Zool. 1892). Southend; near 

 London, by Dr. Power ; Norfolk, Cambridge, Northampton. " Dollar, 

 Edinburgh, Paisley." — Murray's Catalogue. 



(H. brevis, Sahib. Long. 2f ; larg. lj. Closely resembles in form 

 H. nigrita, is half the size ; no trace of longitudinal lines on elytra. 

 Finland. Var. of II. nigrita. ?) 



(II. neuter, Fairmaire. Long. 3-J. Allied to H. nigrita, same 

 colour, slightly larger, more elongated ; head anteriorly reddish, 

 finely punctured; sides of thorax continuing in same line as those of 

 elytra, fully and distinctly punctured : elytra as in H. nigrita, more 

 pubescent. This species differs from II. melanarius by its form, not
