This species a good deal resembles P. Depurator at first ibt 
but a very slight examination will evince the characteristic di- 
stinctions.. The surface is minutely granulated, the shell is nar- 
rower behind, the eyes smaller, and the antennz shorter.

the hinder feet of the same colour. Other feet greenish-livid in- 
clining to blueish. Fingers obscure with white tips.
