8 CARABID^E. DROMIUS. 



rounded at the shoulders, widest behind the middle, sides almost 

 linear, much elongated, obsoletely striated, pale testaceous, with 

 the suture fuscous, the obscure colour gradually widening 

 towards the apex till it joins a large and often roundish spot of 

 the same colour just before the extremity ; legs pale testaceous. 

 Length 2| lines. 



This rare species may readily be recognized by its very elon- 

 gate form and its oblong head. It was first captured in this 

 country at Madingley Wood, near Cambridge, in 1831, and has 

 been occasionally found since in the sedge-boats on the river 

 Cam. In July 1847 I secured three specimens, and in Sep- 

 tember 1850 a fourth among herbage in Holme Fen, not far 

 from Whittlesea Mere.
