  in 
  the 
  sixth, 
  nearly 
  opposite 
  that 
  in 
  the 
  third 
  ; 
  and 
  two 
  (one 
  

   behind 
  the 
  other) 
  at 
  the 
  shoulder. 
  The 
  colouring 
  of 
  the 
  scales 
  

   vary 
  somewhat 
  in 
  different 
  individuals, 
  and 
  the 
  markings 
  are 
  

   often 
  very 
  indistinct 
  ; 
  usually 
  the 
  scales 
  are 
  brown, 
  but 
  on 
  the 
  

   sides 
  and 
  fore 
  part 
  of 
  the 
  thorax 
  of 
  a 
  very 
  pale 
  ash 
  colour, 
  in- 
  

   clining 
  to 
  white, 
  and 
  sometimes 
  with 
  a 
  faint 
  greenish 
  tint 
  : 
  a 
  pale 
  

   undefined 
  band 
  crosses 
  the 
  elytra, 
  running 
  obliquely 
  inwards 
  from 
  

   the 
  shoulder 
  almost 
  to 
  the 
  suture 
  near 
  the 
  middle 
  ; 
  below 
  and 
  

   external 
  to 
  this 
  is 
  a 
  small 
  patch, 
  which 
  is 
  sometimes 
  connected 
  

   with 
  a 
  patch 
  at 
  the 
  apex 
  ; 
  these 
  markings 
  are 
  of 
  the 
  same 
  pale 
  

   colour 
  as 
  the 
  sides 
  of 
  the 
  thorax. 
  The 
  legs 
  are 
  moderate 
  as 
  to 
  

   length, 
  and 
  clothed 
  with 
  scales 
  and 
  short 
  setae: 
  the 
  femora 
  are 
  

   nearly 
  linear 
  and 
  without 
  teeth.

  Proportionably 
  shorter 
  and 
  broader 
  than 
  P. 
  Chevrolatii, 
  the 
  

   thorax 
  less 
  convex, 
  less 
  produced 
  in 
  front 
  ; 
  elytra 
  with 
  the 
  tu- 
  

   bercles 
  larger, 
  and 
  the 
  two 
  conical 
  processes 
  with 
  which 
  they 
  are 
  

   terminated 
  also 
  larger 
  ; 
  the 
  antennae 
  more 
  slender. 
  

  

  Head 
  and 
  rostrum 
  together 
  about 
  equal 
  to 
  the 
  thorax 
  in 
  length; 
  

   rostrum 
  somewhat 
  rugosely 
  punctured, 
  the 
  punctures 
  more 
  nu- 
  

   merous 
  on 
  the 
  apical 
  portion, 
  where 
  there 
  are 
  some 
  delicate 
  longi- 
  

   tudinal 
  ridges 
  on 
  either 
  side 
  ; 
  head 
  nearly 
  flat 
  in 
  front, 
  with 
  a 
  

   faint 
  longitudinal 
  depression 
  in 
  the 
  middle, 
  and 
  a 
  somewhat 
  indis- 
  

   tinct 
  angular 
  depression 
  at 
  the 
  base 
  of 
  the 
  rostrum 
  ; 
  the 
  surface 
  

   impunctate, 
  but 
  with 
  large 
  and 
  small 
  scales 
  in 
  tolerable 
  abun- 
  

   dance. 
  Thorax 
  with 
  the 
  length 
  and 
  width 
  equal, 
  the 
  upper 
  sur- 
  

   face 
  nearly 
  flat 
  in 
  front 
  and 
  near 
  the 
  sides, 
  the 
  mesial 
  portion 
  

   slightly 
  convex, 
  with 
  a 
  short 
  keel, 
  and 
  a 
  rounded 
  tubercle 
  on 
  either 
  

   side 
  at 
  a 
  short 
  distance 
  from 
  the 
  keel. 
  From 
  these 
  tubercles 
  a 
  ridge, 
  

   which 
  is 
  obtuse 
  and 
  but 
  little 
  raised, 
  and 
  runs 
  forwards 
  towards 
  

   the 
  apex 
  of 
  the 
  thorax, 
  and 
  a 
  third 
  ridge, 
  or, 
  it 
  may 
  almost 
  be 
  

   termed, 
  a 
  denuded 
  line, 
  runs
