  Male 
  : 
  Black, 
  with 
  the 
  elytra 
  brownish 
  red 
  ; 
  clothed 
  on 
  the 
  

   prothorax, 
  under 
  side 
  and 
  legs 
  with 
  a 
  very 
  dense 
  ashy-grey 
  pubes- 
  

   cence. 
  Similar 
  in 
  shape 
  and 
  sculpture 
  to 
  the 
  preceding 
  species, 
  

   but 
  the 
  head 
  is 
  a 
  little 
  more 
  coarsely 
  granulose, 
  and 
  the 
  clypeus, 
  

   instead 
  of 
  being 
  parabolic, 
  is 
  straight 
  at 
  the 
  apex 
  with 
  the 
  angles 
  

   sharp 
  ; 
  the 
  prothorax 
  is 
  plainly 
  grooved 
  longitudinally 
  ; 
  the 
  elytra 
  

   have 
  a 
  short 
  but 
  deep, 
  basal, 
  supra-humeral 
  impression, 
  and 
  are 
  

   slightly 
  impressed 
  longitudinally 
  along 
  the 
  median 
  part 
  of 
  the 
  

   suture, 
  they 
  are 
  moderately 
  closely 
  punctured, 
  each 
  puncture 
  

   bearing 
  an 
  appressed 
  short 
  blackish 
  hair; 
  the 
  anterior 
  tibiae 
  are 
  

   bi-dentate 
  outwardly, 
  the 
  hind 
  femora 
  are 
  robust, 
  and 
  the 
  tibiae 
  

   dilated 
  triangularly 
  towards 
  the 
  apex 
  the 
  two 
  angles 
  of 
  which 
  are 
  

   greatly 
  developed, 
  the 
  inner 
  one 
  being 
  plainly 
  mucronate, 
  there 
  is 
  a 
  

   long 
  apical 
  spur. 
  

  

  Female 
  unknown. 
  Eesembles 
  somewhat 
  P. 
  excentrus, 
  but 
  is 
  

   distinguished 
  by 
  the 
  straight 
  clypeus, 
  the 
  much 
  less 
  densely 
  punc- 
  

   tured 
  elytra 
  ; 
  the 
  hind 
  tibiae 
  are 
  not 
  quite 
  as 
  plainly 
  mucronate 
  as 
  

   Burmeister 
  states, 
  and 
  resemble 
  those 
  of 
  P. 
  glabratus, 
  hoplioides, 
  

   and 
  excentrus.
