  (fig.

  eyes 
  distinctly 
  but 
  not 
  densely 
  hairy 
  (almost 
  bare 
  in 
  P. 
  nigripes 
  

   and 
  homoea). 
  Vertex 
  and 
  frons 
  to 
  the 
  suture 
  smooth 
  and 
  gleaming, 
  the 
  surface 
  hardly 
  

   disturbed,

  along 
  the 
  edge 
  of 
  the 
  occiput,

  space 
  between 
  the

  the

  only 
  a 
  little 
  less

  Antennae 
  short, 
  compact, 
  shining 
  dark 
  blue 
  ; 
  funicular 
  joints 
  thick,

  Mid

   with 
  moderately 
  fine 
  reticulation, 
  hardly 
  at 
  all 
  raised 
  (coarse 
  and 
  raised

  nigripes), 
  

   and 
  drawn 
  out 
  towards 
  the 
  apex, 
  at 
  the 
  side 
  of 
  which 
  are 
  two 
  setigerous 
  foveolae, 
  

   the 
  setae 
  being 
  on

  slightly 
  raised 
  base. 
  Over
