Locally distributed on the coast, occurring between tide-marks. 

 Mr. Haliday, in a note on this interesting species, writes as follows : — 

 ^'They prey upon sandhoppers (TaZ^Yr^<s Zocustra, Leach.), seizing 

 them by the soft parts of the underside, and, in this way, are able 

 singly to master game many times their own bulk. Sometimes three 

 or four beetles may be found in concert attacking a sandhopper of the 

 largest size. The tide retiring has scarcely uncovered the sand, when 

 these little depredators are abroad from their hiding-places and alert 

 in the chase." Distribution — local on the coasts of England (south 

 especially) and Wales, Scotland (south). Eeitter records it from the 

 coasts of west-central Europe.
