252 Dr. Sharp's Bevision of the 



Mas; abdomine segmento 7° ventrali margine pos- 

 teriore rotundato. 



Fern. ; abdomine segmento 7° ventrali apice medio ex- 

 ciso. 



Smaller than If . atramentaria, the anterior parts blacker 

 and more shining, the antennae shorter and more thick- 

 ened towards the apex. The antennae are black, the 

 basal joint pitchy; they are distinctly thickened towards 

 the apex, and furnished throughout with exserted hairs 

 much as in H. atramentaria; joints two and three mo- 

 derately long, three scarcely so long as two, four to ten 

 each a little broader than its predecessor, of four and 

 five the length differs little from the breadth, the fol- 

 lowing joints gradually more transverse, the penulti- 

 mate ones distinctly transverse ; the eleventh joint 

 is rather long, quite as long as the two preceding 

 together. The head is of moderate size, a little narrower 

 than the thorax, its punctuation moderately close, and 

 rather rough. The thorax is distinctly narrower than 

 the elytra, about one-third broader than long, the sides 

 gently rounded in front, then slightly narrowed behind, 

 not narrower at the anterior than at the posterior angles, 

 rather closely and strongly punctured, the sides with a 

 few exserted setse. The elytra are about a third longer 

 than the thorax, pitchy-black or pitchy, pretty closely 

 and strongly punctured. The abdomen is black and 

 shining*, moderately narrowed towards the apex, seg- 

 ments two to four distinctly but not closely punctured, 

 fifth segment more sparingly punctured, sixth nearly 

 impunctate, the sides and apex furnished distinctly with 

 outstanding setae. The legs are pitchy, the four posterior 

 tibiae with two fine, rather short, exserted setae. 



In the male, the upper plate of the seventh abdominal 

 segment is without any peculiar structure, and the hind 

 margin of the under plate is gently rounded ; while in 

 the female this plate is distinctly excised in the middle^ 

 and the hind margin ciliate. 



Generally distributed, in dung, but not very common. 



Obs. — This species is confounded in collections both 

 with H. atramentaria and S. parva. I have mentioned 

 above, characters which will distinguish it from the 

 former. From H. parva, its more thickened antennae, 

 broader head, less transverse thorax (which is also less 

 narrowed in front) , rather more sparing punctuation, and 

 the shorter lower setae of its tibiae, distinguish it.
