262 Dr. Sharp's Revision of the 



eleventh joint rather stout^ gently pointed, scarcely so 

 long as the two preceding together. The head is con- 

 siderably narrower than the thorax, rather broad and 

 shorty black, closely and distinctly punctured, palpi 

 3^ellowish. The thorax is broad, at the base as broad as 

 the elytra, about twice as broad as long, the sides gently 

 rounded, a little narrower at the anterior than at the 

 posterior angles, of an obscure fuscous colour, a little 

 paler at the sides, closely and distinctly punctured, with 

 a central longitudinal channel, pubescence fine and short, 

 exserted setae at the sides almost none. The elytra are 

 about a third longer than the thorax, of a yellowish 

 colour, closely and pretty distinctly punctured. The 

 abdomen is distinctly narrowed towards the apex, and is 

 of a blackish colour with the extremity paler, segments 

 two to four closely and rather finely, five and six more 

 sparingly and finely, punctured; the outstanding setsa 

 at the sides not numerous. The legs are yellow, the 

 tibiae without exserted setse. 



In the male, the hind margin of the dorsal plate of the 

 seventh abdominal segment is furnished with four dis- 

 tinct teeth ; they are about equidistant from one another, 

 the external ones rather finer and longer than the inner 

 ones, but the notch between the two inner ones is a 

 little the deeper. 



In the female, the hind margin of the seventh seg- 

 ment is simple, both above and below. 



Common, both in England and Scotland. 



Obs. — It is stated, both by Kraatz and Thomson, that 

 the seventh ventral abdominal plate is emarginate in the 

 female of this species. This, however, I do not find to 

 be the case.
