CARABID.E. BEMBIDIUM. 185 



narrower, antennae longer, smoother at the base, the penultimate 

 joint of the palpi pitchy. Thorax very convex, narrow, oblong- 

 cordate, contracted behind, the dorsal furrow finer, the transverse 

 impression in front only slightly strigose, the basal fovese smaller 

 and the space between them more delicately punctured. Elytra 

 more elongate and convex, the punctured strise more distinct on 

 the sides, the exterior one being very evident, but the punctures 

 disappear from all the striae sooner as they approach the apex 

 which is quite smooth, the testaceous spots are similar and the 

 legs are also pale. Length 3 lines. 



This insect is for the first time introduced into the British 

 fauna from a fine series of specimens received from Mr. Hadfield, 

 of Newark, who captured them on the banks of the Trent at 

 Kelham.

This species is considerably broader than littorale. Thorax 

 wider and less convex, the sides more dilated and rounded, the 

 base broader and less strongly punctured and the basal fovese 

 less rugged. Elytra about twice the width of the thorax at the 

 base, depressed, profoundly punctate- striated, but the apex 

 smooth, obscure greenish bronze, with a large obliquely-formed 

 or semilunate testaceous spot common to both before the apex ; 

 legs also pale testaceous. Length 3 lines. 



P. ustus, Steph., is a mature example of this species. The 

 true C. ustus of Schonherr has not been taken in Britain. 



Abundant on the banks of the Irthing and other places in the 

 north of England; on the shores of the Humber; in Norfolk, &c. 



16. B. saxatile: obscure viridi-ceneum; thorace subcordato, postice 

 punctulato; elytris oblongis, subparallelis,/or/z/er punctato- 

 striatis, striis omnino integris, maculis duabus magnis rufo- 

 testaceis ; antennis basi pedibusque rufis.
