  This 
  paper 
  is 
  the 
  fifth 
  of 
  a 
  series 
  published 
  in 
  this 
  periodical 
  

   relating 
  to 
  the 
  Histeridse. 
  The 
  first 
  appeared 
  in 
  1884, 
  the 
  

   second 
  and 
  third 
  in 
  1885, 
  and 
  the 
  fourth 
  in 
  1888. 
  The 
  

   aggregate 
  number 
  of 
  species 
  treated 
  of 
  in 
  the 
  several 
  memoirs 
  

   is 
  181.

  This 
  species 
  is 
  nearly 
  as 
  broad 
  again 
  as 
  P. 
  mandibulars. 
  

   Mars, 
  (with 
  the 
  type 
  of 
  which 
  it 
  has 
  been 
  compared), 
  but 
  its 
  

   general 
  similarity 
  is 
  greater 
  to 
  that 
  than 
  to 
  any 
  other 
  known 
  

   species. 
  The 
  frontal 
  median 
  elevation 
  or 
  tubercle 
  is 
  not 
  con- 
  

   spicuous, 
  otherwise 
  it 
  might 
  be 
  said 
  to 
  correspond 
  with 
  P. 
  

   monodon, 
  Mars., 
  in 
  this 
  particular. 
  The 
  elevated 
  median 
  line 
  

   on 
  the 
  pygidium 
  is 
  very 
  distinct 
  between 
  the 
  two 
  foveas, 
  but 
  it 
  

   is 
  evanescent 
  at 
  the 
  centre. 
  The 
  pygidium 
  is 
  punctured 
  in 
  

   the 
  middle, 
  with 
  a 
  smooth 
  margin 
  somewhat 
  like 
  that 
  of
