  CAMERON, 
  Hymenoptera 
  Orientalia. 
  

  

  transversely 
  striated. 
  Legs 
  black, 
  the 
  apex 
  of 
  the 
  hinder 
  

   tibiae 
  and 
  the 
  hinder 
  tarsi 
  fulvo-testaceous. 
  Wings 
  hyaline, 
  

   the 
  apex 
  and 
  a 
  spot 
  below 
  the 
  basal 
  two-thirds 
  of 
  the 
  

   stigma, 
  extending 
  on 
  the 
  lower 
  side 
  slightly 
  beyond 
  the 
  

   cubital 
  nervure, 
  brownish 
  ; 
  the 
  nervures 
  blackish 
  ; 
  the 
  

   first 
  transverse 
  cubital 
  nervure 
  fuscous, 
  almost 
  obliterated 
  

   on 
  the 
  lower 
  side 
  ; 
  the 
  second 
  very 
  faint, 
  except 
  at 
  the 
  top. 
  

   Abdomen 
  smooth, 
  shining, 
  the 
  apex 
  of 
  the 
  last 
  segment 
  

   pale 
  ; 
  the 
  petiole 
  distinctly 
  separated, 
  three 
  times 
  as 
  long 
  

   as 
  broad. 
  

  

  This 
  species 
  belongs 
  to 
  the 
  small 
  group, 
  named 
  by 
  

   Westwood 
  Aulacinus, 
  distinguishing 
  by 
  having 
  three 
  

   complete 
  cubital 
  cellules. 
  The 
  first 
  cubital 
  cellule 
  at 
  the 
  

   top 
  is 
  about 
  one-third 
  of 
  the 
  length 
  of 
  the 
  top 
  of 
  the 
  

   second 
  ; 
  at 
  the 
  bottom 
  the 
  two 
  are 
  about 
  equal 
  in 
  length 
  ; 
  

   the 
  recurrent 
  nervure 
  is 
  received 
  somewhat 
  less 
  than 
  the 
  

   length 
  of 
  the 
  top 
  of 
  the 
  first 
  cubital 
  cellule 
  from 
  the 
  

   second 
  transverse 
  cubital 
  nervure. 
  The 
  form 
  of 
  the 
  

   discoidal 
  cellule 
  is 
  also 
  as 
  in 
  Aulacinus, 
  i.e., 
  the 
  first 
  

   recurrent 
  nervure 
  is 
  not 
  united 
  with 
  the 
  first 
  transverse 
  

   cubital 
  nervure, 
  but 
  received 
  considerably 
  in 
  front 
  of 
  it. 
  

  

  WROUGHTONIA, 
  gen. 
  nov. 
  

  

  Front 
  depressed, 
  in 
  the 
  centre 
  immediately 
  over 
  the 
  

   antennas 
  armed 
  with 
  a 
  large, 
  stout 
  tooth, 
  which 
  is 
  bluntly 
  

   rounded 
  at 
  the 
  apex. 
  Labrum 
  large, 
  rounded. 
  Mandibles 
  

   stout, 
  short, 
  with 
  one 
  blunt, 
  short 
  upper 
  tooth 
  on 
  the 
  apex 
  

   as 
  seen 
  from 
  the 
  inside. 
  Eyes 
  oval, 
  not 
  reaching 
  to 
  the 
  

   base 
  of 
  the 
  mandibles. 
  Scutellum 
  pryramidal. 
  Meta- 
  

   thorax 
  elongate. 
  Wings 
  with 
  two 
  transverse 
  cubital 
  

   nervures 
  and 
  consequently 
  two 
  cubital 
  cellules 
  ; 
  the 
  cubital 
  

   nervure 
  originates 
  near 
  the 
  top 
  of 
  the 
  transverse 
  basal 
  ; 
  

   the 
  first 
  recurrent 
  nervure 
  is 
  received 
  in 
  the 
  apical 
  third 
  of 
  

   the 
  first 
  cubital 
  nervure 
  ; 
  the 
  others 
  are 
  obliterated
