, Erich., Nat. der Ins. Deutsch. iii. 338 (1848), 
S. elongate, narrow and parallel, depressed, ferruginous, slightly 
pubescent, and opake. Head and prothorax deeply and closely 
rugulose and punctate: the former with the sides nearly straight 
(though oblique) and slightly raised; and armed with a small 
denticle, or projection, immediately below (and touching) either 
eye: the latter elongated, and gradually narrowed posteriorly ; 
free from ridges and grooves, and with its anterior angles pro- 
duced into a long and spiniform process; minutely scooped-out 
(on the wpper surface, or pronotum) at its posterior angles,—the 
space between the front end of this excavation and the anterior 
angles (amounting to nearly the entire length of the sides) being 
most obscurely crenulated. Hlytra generally a little paler than 
the head and prothorax; punctate-striated, the alternate inter- 
stices being scarcely perceptibly raised. Limbs as pale as (and 
perhaps a little more rufescent than) the elytra. 


The above addition to our fauna was detected by Mr. Bewicke (by 
whom the specimens in the British Museum were presented) beneath
