  Head 
  (fig. 
  7, 
  b) 
  : 
  sculpture 
  of 
  the 
  vertex 
  distinct, 
  though 
  not 
  so 
  pronounced 
  

   or 
  raised 
  as 
  on 
  the 
  thorax, 
  agreeing 
  in 
  this 
  respect 
  with 
  P. 
  clinognathus. 
  The 
  

   hollows 
  behind 
  the 
  posterior 
  ocelli 
  distinct, 
  smooth 
  extensively 
  towards 
  the 
  eye 
  

   margins 
  ; 
  reticulation 
  most 
  distinct 
  within 
  the 
  ocellar 
  triangle. 
  Eyes 
  almost 
  bare, 
  the 
  

   pubescence 
  short 
  and 
  sparse. 
  Mandibles 
  nofc 
  deeply 
  bidentate 
  (fig. 
  5,/), 
  inner 
  tooth 
  

   broader, 
  with 
  its 
  inner 
  edge 
  shortly 
  serrate 
  at 
  the 
  apex. 
  Antennae 
  entirely 
  dark 
  and 
  

   metallic, 
  pedicel 
  short, 
  first 
  joint 
  of 
  funicle 
  longest 
  and 
  broadest.

  Thorax 
  : 
  pronotum 
  smooth 
  and 
  shining, 
  but 
  behind 
  the 
  anterior 
  ridged 
  edge 
  are 
  

   numerous 
  very 
  short 
  subparallel 
  ridges 
  not 
  reaching 
  beyond 
  one-third 
  backwards 
  ; 
  

   they 
  are 
  imperceptible 
  separately 
  save 
  in 
  a 
  good 
  light, 
  but 
  their 
  effect 
  is 
  to 
  make 
  the 
  

   anterior 
  edge 
  duller. 
  Mesonotum 
  with 
  the 
  mid 
  lobe 
  rather 
  coarsely 
  reticulate 
  to 
  the 
  

   level 
  of 
  the 
  posterior 
  (apical) 
  pair 
  of 
  bristles, 
  the 
  pattern 
  being 
  raised. 
  From 
  the 
  

   bristles 
  to 
  the 
  scutellum 
  the 
  apex 
  of 
  the 
  mid 
  lobe 
  is 
  striate, 
  only 
  the 
  longitudinal 
  

   lines 
  of 
  the 
  reticulate 
  pattern 
  being 
  raised. 
  Before 
  the 
  scutellum 
  the 
  furrows 
  are 
  

   rather 
  deeply 
  marked 
  for 
  a 
  short 
  distance. 
  Lateral 
  lobes 
  and 
  axillae 
  mainly 
  

   striate-reticulate. 
  Scutellum 
  antero-medianly 
  smooth, 
  shining 
  and 
  impunctate, 
  

   as 
  in 
  P. 
  neavei, 
  but 
  less 
  broadly 
  so 
  (J 
  as 
  opposed 
  to 
  ^) 
  with 
  about 
  five 
  ridges 
  on 
  

   each 
  side. 
  The 
  smooth 
  median 
  area 
  continues 
  to 
  the 
  metanotum, 
  before 
  which 
  there 
  

   is 
  at 
  most 
  a 
  weak 
  striation 
  with 
  feeble 
  reticulation. 
  The 
  posterior 
  third 
  is 
  not, 
  as 
  

   in 
  P. 
  neavei, 
  raised 
  again 
  into 
  a 
  bold 
  pattern. 
  Propodaeum 
  narrower 
  than 
  in 
  

   P. 
  neavei, 
  the 
  posterior 
  knob 
  broad 
  ; 
  within 
  the 
  median 
  keels 
  is 
  a 
  secondary 
  central 
  

   keel 
  running 
  the 
  whole 
  length 
  of 
  the 
  enclosed 
  space 
  ; 
  distally 
  on 
  both 
  sides 
  the 
  

   preapical 
  hollows 
  are 
  shining. 
  

  

  Wings: 
  fore 
  wings 
  apically 
  rounded; 
  length 
  1-2 
  mm.; 
  breadth, 
  -55 
  mm. 
  

   hind 
  wings, 
  length, 
  *95 
  mm. 
  ; 
  breadth, 
  -25 
  mm.
