108 COLEOPTERA. 



§ B. (abdomen cylindrical, not margined). Its small size, 

 scarcely exceeding one line, will suffice to distinguish it from 

 the species belonging to the same group and section hitherto 

 ascertained to be indigenous. 



I have seen a single native specimen only of this species, 

 which was captured by Mr. H. Squire in Homing Fen, in 

 the autumn of 1858 $ it is in the collection of Mr. Jeakes.

 From the above references it might be deduced that the 

 specific title of proboscideus should be adopted for the pre- 

 sent species ; but no authentic type of Olivier's insect being 

 now extant, it is impossible to determine the species he had 

 in view, his description and figure apply equally well to 

 several pale-legged species ; moreover, he describes, and the
