  CAMERON, 
  Hymenoptera 
  Orientalia. 
  

  

  mesopleurae 
  ; 
  the 
  spiracular 
  region 
  is 
  bounded 
  by 
  two 
  

   keels 
  and 
  is 
  strongly 
  transversely 
  punctured. 
  The 
  tibiae 
  

   and 
  tarsi 
  are 
  spinose, 
  the 
  coxae 
  thickly, 
  the 
  femora 
  more 
  

   sparsely 
  covered 
  with 
  shorter, 
  white 
  hair. 
  The 
  petiole 
  is 
  

   black, 
  except 
  at 
  the 
  apex 
  ; 
  the 
  second 
  segment 
  has 
  the 
  

   basal 
  third 
  black 
  ; 
  the 
  sheaths 
  of 
  the 
  ovipositor 
  black. 
  

   On 
  the 
  median 
  segment 
  there 
  are 
  five 
  clearly 
  defined 
  

   areae, 
  besides 
  a 
  small 
  central 
  one 
  at 
  the 
  base; 
  the 
  spiracular 
  

   region 
  has 
  two 
  complete 
  keels 
  ; 
  the 
  tibiae 
  and 
  tarsi 
  are 
  

   more 
  strongly 
  spinose 
  than 
  usual 
  ; 
  the 
  spines 
  on 
  the 
  claws 
  

   are 
  stout.

   segment 
  small,

  Wings 
  short 
  ; 
  the 
  recurrent 
  nervure 
  

   is 
  received 
  on 
  the 
  outer 
  side 
  of 
  the 
  first 
  transverse 
  cubital 
  ; 
  

   the 
  transverse 
  basal 
  nervure 
  is

  from 
  which 
  it 
  

   differs 
  in 
  the 
  absence 
  of 
  an 
  areolet, 
  in 
  the 
  transverse 
  

   basal 
  nervure 
  being 
  interstitial, 
  in 
  the 
  greatly 
  elongated 
  

   ovipositor,
