antennas, and the hinder angles of its thorax not being pro- 

 minent, or even slightly recurved, as in that species; and 

 from C. tristis by the obsolete club of its antennae, in which 

 all the joints are much narrower, the eighth being stouter, 

 and the apical more elongate : the club in C, tristis being 

 abrupt, with the 8th joint small, shallow, and very trans- 

 verse, and the apical joint short. 



\yithout detailing other characters it may suffice to say 

 that the oblon^-oval elytra, at least four times the length of 

 the thorax, will distinguish this species from all its British 

 congeners. 



I detected a single example among some Cholevce taken 

 near Newcastle by my friend, Mr. T. J. Bold ; who sub- 

 sequently found another specimen, which (with his usual 

 liberality) he gave to me.

I took a single example, of what I suppose to be this spe- 

 cies, at Coombe Wood, in the autumn of last year. 



'It resembles S. aguricina in size and shape, but differs 

 in having its elytra more thickly punctured and pitchy black, 

 with the apical half and lateral margins reddish-brown ; the 

 antennae, also, have the seventh, ninth, tenth, and eleventh 

 joints equal, and narrower, and more attenuate than in that 

 species, the eighth being scarcely shorter, and but a little 

 thinner, than any of these joints. 



From S. boleti it should be known by its narrower build, 

 longer thorax, darker colour, and much more thickly punc- 

 tured elytra, which have the sutural striae more distinct, and 

 the suture itself broadly keeled ; also by the seventh joint of 

 its antennae not beins wider than the rest.
