  ONTSIRA, 
  gen. 
  nov. 
  

  

  Occiput 
  margined. 
  Mesonotum 
  trilobate, 
  the 
  middle 
  

   lobe 
  furrowed 
  in 
  the 
  centre. 
  Median 
  segment 
  with 
  ten 
  

   clearly 
  defined 
  areae. 
  Wings 
  with 
  three 
  cubital 
  cellules 
  ; 
  the 
  

   apical 
  abscissa 
  of 
  the 
  radius 
  curved 
  upwards; 
  the 
  transverse 
  

   probrachial 
  nervure 
  interstitial 
  ; 
  the 
  anal 
  nervure 
  inter- 
  

   stitial 
  ; 
  the 
  hind 
  wings 
  with 
  only 
  one 
  longitudinal 
  nervure. 
  

   Head 
  cubital 
  ; 
  largely 
  developed 
  behind 
  the 
  eyes, 
  but 
  not 
  

   projecting 
  beyond 
  them 
  laterally. 
  Oral 
  region 
  as 
  in 
  

   Bracon; 
  the 
  mandibles 
  with 
  a 
  sharp 
  apical 
  tooth. 
  Probra- 
  

   chial 
  areolet 
  as 
  long 
  as 
  praebrachial 
  ; 
  the 
  radial 
  nervure 
  

   in 
  hind 
  wings 
  obsolete 
  ; 
  the 
  probrachial 
  cellule 
  divided 
  

   into 
  two 
  by 
  a 
  nervure. 
  

  

  The 
  eyes 
  are 
  prominent 
  and 
  distinctly 
  distant 
  from 
  

   the 
  base 
  of 
  the 
  mandibles 
  ; 
  the 
  antennae 
  have 
  over 
  twenty 
  

   joints 
  ; 
  the 
  apical 
  ones 
  are 
  broken 
  off; 
  on 
  the 
  under 
  side 
  

   of 
  the 
  mesopleurse 
  is 
  a 
  wide 
  longitudinal 
  furrow 
  ; 
  the_ 
  

   petiole 
  is 
  widely 
  and 
  deeply 
  depressed 
  at 
  the 
  base 
  ; 
  the 
  

   abdominal 
  segments 
  are 
  smooth, 
  without 
  punctures 
  or 
  

   depressions 
  of 
  any 
  kind 
  ; 
  there 
  is 
  no 
  securiform 
  articu- 
  

   lation 
  ; 
  the 
  separation 
  of 
  the 
  segments 
  is 
  hardly 
  

  

  distinguishable 
  ; 
  the 
  hinder 
  coxae 
  at 
  the 
  base 
  have 
  a 
  

  

  perpendicular 
  slope 
  and 
  are 
  roundly 
  incised 
  there, 
  and 
  

   in 
  the 
  centre 
  beneath 
  project 
  into 
  a 
  short, 
  somewhat 
  

   conical, 
  tooth 
  ; 
  the 
  trochanters 
  are 
  rather 
  longer 
  than 
  

   usual 
  ; 
  the 
  four 
  anterior 
  tibiae 
  are 
  slightly 
  bent 
  at 
  the 
  

   base 
  ; 
  the 
  calcaria 
  are 
  very 
  short 
  ; 
  the 
  claws 
  simple. 
  In 
  

   the 
  hind 
  wings 
  the 
  costal 
  and 
  praebrachial 
  cellules 
  are 
  

   distinct 
  ; 
  the 
  probrachial 
  nervure 
  is 
  united 
  to 
  the 
  prae- 
  

   brachial 
  ; 
  and 
  in 
  the 
  middle 
  of 
  the 
  probrachial 
  cellule 
  is 
  an 
  

   oblique 
  nervure 
  dividing 
  it 
  into 
  two 
  ; 
  the 
  radius 
  is 
  

   obsolete; 
  the 
  cubitus 
  complete, 
  extending 
  to 
  the 
  apex 
  ; 
  the 
  

   probrachial 
  nervure 
  is 
  obsolete 
  ; 
  the 
  probrachial 
  and 
  the 
  

   anal 
  cellules 
  being 
  thus 
  united 
  into 
  one.
