  Cameron, 
  Hymenoptera 
  Orientalia. 
  

  

  the 
  third 
  ; 
  there 
  is 
  no 
  areolet 
  in 
  the 
  fore 
  wings 
  ; 
  the 
  

   scutellum 
  is 
  large, 
  pyramidal, 
  broadly 
  keeled 
  laterally 
  ; 
  

   the 
  median 
  area 
  has 
  only 
  the 
  basal 
  or 
  middle 
  areae 
  

   defined, 
  and 
  is 
  laterally 
  armed 
  with 
  large 
  teeth 
  or 
  with 
  a 
  

   plate. 
  Eyes 
  large, 
  widely 
  distant 
  from 
  the 
  base 
  of 
  the 
  

   mandibles 
  ; 
  behind 
  them, 
  at 
  the 
  top, 
  the 
  orbits 
  are 
  hardly 
  

   developed 
  and 
  they 
  are 
  distinctly 
  margined 
  next 
  to 
  the 
  

   eyes. 
  Antennae 
  dilated 
  and 
  compressed 
  towards 
  the 
  apex. 
  

   Clypeus 
  not 
  distinctly 
  separated 
  from 
  the 
  face 
  ; 
  foveate 
  

   on 
  the 
  sides 
  at 
  the 
  base 
  ; 
  its 
  apex 
  rounded. 
  Mandibles 
  

   triangular, 
  with 
  only 
  one 
  apical 
  tooth. 
  Thorax 
  large, 
  

   with 
  indistinct 
  parapsidal 
  furrows, 
  the 
  mesopleurae 
  with 
  a 
  

   longitudinal 
  furrow 
  on 
  the 
  lower 
  side. 
  Abdominal 
  petiole 
  

   large, 
  its 
  apical 
  half 
  dilated 
  ; 
  there 
  are 
  no 
  gastrocceli. 
  

   The 
  last 
  ventral 
  segment 
  is 
  large 
  ; 
  the 
  ovipositor 
  

   originates 
  from 
  its 
  base. 
  The 
  base 
  of 
  the 
  basal 
  joint 
  of 
  

   the 
  fore 
  tarsi 
  is 
  largely 
  curved, 
  almost 
  incised 
  ; 
  the 
  long 
  

   spur 
  of 
  the 
  tibiae 
  is 
  curved. 
  

  

  The 
  form 
  of 
  the 
  abdomen 
  — 
  in 
  having 
  only 
  three 
  

   dorsal 
  segments 
  visible 
  — 
  resembles 
  that 
  of 
  Rothneyia, 
  but 
  

   in 
  other 
  respects 
  it 
  is 
  very 
  different 
  from 
  that 
  genus.
