  somewhat 
  metallic 
  green, 
  but 
  the 
  elytra 
  have 
  not 
  only 
  along 
  the 
  

   suture 
  a 
  broad 
  band 
  of 
  very 
  dense 
  and 
  somewhat 
  long, 
  lanceolate 
  

   appressed 
  white 
  hairs, 
  but 
  the 
  long 
  impression 
  along 
  the 
  humeral 
  

   callus 
  is 
  filled 
  with 
  a 
  band 
  of 
  similar 
  hairs 
  ; 
  the 
  scutellum 
  is 
  densely 
  

   hairy, 
  and 
  the 
  hairs 
  white 
  ; 
  the 
  appressed 
  hairs 
  on 
  the 
  pygidium 
  are 
  

   white 
  in 
  both 
  sexes 
  ; 
  the 
  anterior 
  tibiae 
  are 
  strongly 
  and 
  sharply 
  

   tri-dentate, 
  the 
  apical 
  tooth 
  is 
  also 
  broadly 
  separated 
  from 
  the 
  inter- 
  

   mediate 
  one, 
  and 
  the 
  hind 
  claws 
  are 
  double 
  and 
  both 
  parts 
  cleft, 
  but 
  

   the 
  longer 
  one 
  is 
  only 
  cleft 
  laterally, 
  and 
  the 
  lateral 
  part 
  is 
  slender 
  

   and 
  shorter.

  A 
  close 
  ally 
  to 
  P. 
  hottcntotus, 
  but 
  much 
  smaller 
  ; 
  the 
  elytra 
  are 
  

   darker 
  brown 
  ; 
  the 
  head 
  and 
  prothorax 
  are 
  similar, 
  the 
  latter 
  being 
  

   more 
  distinctly 
  dark 
  green, 
  but 
  the 
  pubescence 
  which 
  covers 
  it 
  is 
  

   much 
  shorter 
  ; 
  the 
  scutellum 
  is 
  also 
  hairy, 
  but 
  the 
  hairs 
  are 
  greyish, 
  

   and 
  the 
  elytra 
  have 
  no 
  longitudinal 
  impression 
  along 
  the 
  suture 
  or 
  

   the 
  humeral 
  callus, 
  and 
  are 
  covered 
  equally 
  with 
  greyish 
  appressed 
  

   hairs 
  not 
  as 
  dense 
  as 
  on 
  the 
  pygidial 
  area, 
  abdomen, 
  or 
  pectus, 
  

   where 
  they 
  are 
  flavescent 
  ; 
  anterior 
  tibiae 
  tri-dentate, 
  the 
  teeth 
  are 
  

   sharp 
  and 
  shaped 
  as 
  in 
  P. 
  hottcntotus, 
  and 
  the 
  hind 
  claws 
  are 
  cleft 
  

   in 
  the 
  same 
  manner, 
  but 
  the 
  lateral 
  cleft 
  part 
  of 
  the 
  outer 
  one 
  is 
  

   very 
  slender.
