256 Di'. Sharp's Revision of the 



punctuation, and less developed antennae ; from H. aterri- 

 TTia by its larger size, stouter antennae, coarser punctua- 

 tion, and differently coloured elytra. The antennae are 

 of moderate length and stoutness, but little thickened 

 towards the apex, black, with the basal joint pitchy, dis- 

 tinctly pilose ; joints one and two stout, three longer and 

 more slender than two, four to six each about as long as 

 broad, seven to ten each a little shorter than broad; 

 eleventh joint as long as the two preceding together. 

 The head is broad and short, moderately closely and dis- 

 tinctly punctured. The thorax is ample, as broad as, or 

 broader than the elytra, nearly half as broad again as long, 

 transversely convex, the sides rounded, distinctly nar- 

 rower at the anterior than at the posterior angles, with- 

 out exserted setae at the sides, shining, closely and 

 distinctly punctured. The elytra are but little longer 

 than the thorax, of a livid yellow colour, with a large 

 triangular common black patch, and with the sides also 

 darker, rather strongly and closely, somewhat rugulosely 

 punctured. The abdomen is strongly narrowed towards 

 the apex, closely and distinctly punctured, the sixth seg- 

 ment more sparingly than the basal ones, the pubescence 

 is depressed and pretty dense, the outstanding black 

 setae of the sides, apex, and margins of the segments 

 long and numerous. The legs are pitchy- testaceous, the 

 middle and posterior tibias each with a distinct exserted 

 seta. 



In the male, the ventral plate of the seventh abdominal 

 segment is narrow at the apex and rounded. 



In the female, it is broader, furnished with distinct 

 short, black, parallel cilia, and rather broadly and not 

 deeply emarginate in the middle. 



In dung, not very abundant. I have never found it in 

 Scotland.
