  joint 
  of 
  all 
  the 
  tarsi 
  wholly 
  black, 
  the 
  other 
  three 
  clear 
  white. 
  The 
  apical 
  

   spur

  tibia 
  is

  Abdomen 
  : 
  first 
  tergite 
  occupying 
  half 
  the 
  surface, 
  with 
  a 
  dim 
  triangular 
  median 
  

   area, 
  the 
  apex 
  of 
  which 
  lies 
  behind 
  the 
  petiole, 
  while 
  the 
  base 
  (narrowly 
  separated 
  

   from 
  the 
  suture) 
  extends 
  across 
  the 
  median 
  two-thirds. 
  This 
  dimmer 
  area 
  is 
  caused 
  

   by 
  numerous 
  minute 
  punctures 
  giving 
  rise 
  to 
  microscopic 
  hairs 
  (cf. 
  P. 
  neavei, 
  where 
  

   the 
  surface 
  is 
  actually 
  dull 
  and 
  reticulate). 
  The 
  succeeding 
  segments 
  show, 
  

   (a) 
  a 
  basal 
  shining 
  belt, 
  (b) 
  a 
  minutely 
  punctate 
  or 
  roughened 
  median 
  band, 
  and 
  

   (c) 
  the 
  usual 
  gleaming 
  sutural 
  edging.
