We have carefully compared our series of this and the following 

 species with types named by Dr. Sharp, and find that P. nigritulus is 

 apparently of much more frequent occurrence in Ireland. P. nigritulus 

 may be best recognised through its narrower head, longer elytra, and 

 by the fact that the thorax is slightly narrowed in front, instead of 

 being the same breadth throughout. The legs are usually darker in 

 colour. The species is of world-wide range.

Locally common under seaweed. This species ranges west in 

 Great Britain, being found on the coasts in the south and west of 

 England, Wales, Isle of Man, and Scotland (Forth district). On the 

 Continent it seems recorded only from the French coast.
