  Male 
  : 
  This 
  species 
  is 
  also 
  very 
  closely 
  allied 
  to 
  P. 
  dimidiatus, 
  so 
  

   much 
  so 
  that 
  it 
  is 
  difficult 
  to 
  differentiate 
  them 
  ; 
  it 
  is, 
  however, 
  a 
  little 
  

   smaller, 
  the 
  pubescence 
  on 
  the 
  prothorax 
  is 
  somewhat 
  denser 
  and 
  

   more 
  flavescent 
  ; 
  the 
  elytra 
  of 
  the 
  male 
  are 
  fuscous 
  in 
  the 
  posterior 
  

   part 
  only, 
  not 
  on 
  the 
  sides, 
  the 
  pygidium 
  is 
  much 
  more 
  densely 
  

   covered 
  with 
  flavescent 
  hairs 
  ; 
  the 
  hind 
  tarsi, 
  and 
  also 
  the 
  hind 
  

   tibiae, 
  but 
  the 
  former 
  especially, 
  are 
  very 
  densely 
  villose, 
  the 
  villose 
  

   hairs 
  on 
  the 
  tibiae 
  are 
  yellow, 
  and 
  on 
  the 
  tarsi 
  black. 
  

  

  The 
  female 
  cannot 
  be 
  distinguished 
  from 
  that 
  of 
  P. 
  dimidiatus.

  another 
  

   one,
