  This 
  is 
  finothor 
  anomalous 
  Hawaiian 
  genus 
  allied 
  to 
  Enicospilufi 
  

   but 
  remarkably 
  difFerent 
  in 
  general 
  form, 
  in 
  its 
  lack 
  of 
  the 
  fenestra 
  

   and 
  in 
  the 
  strongly 
  exserted, 
  recurved 
  ovipositor 
  and 
  obsolete 
  post- 
  

   pectoral 
  carina. 
  The 
  wing 
  venation 
  is 
  nearly 
  the 
  same 
  as 
  in 
  Bancho- 
  

   gastra, 
  but 
  the 
  form 
  of 
  the 
  body 
  is 
  very 
  different. 
  

  

  Head: 
  Rather 
  thick, 
  temples 
  narrow, 
  weakly 
  convex 
  and 
  very 
  

   sharply 
  receding; 
  occiput 
  narrow 
  and 
  weakly 
  concave, 
  carina 
  complete; 
  

   eyes 
  large 
  and 
  bulging, 
  deeply 
  emarginate; 
  vertex 
  narrow; 
  stemma-

  not 
  elevated, 
  ocelli 
  small, 
  not 
  touching 
  eyes; 
  malar 
  space 
  dis- 
  

   tinct; 
  mandible 
  twisted, 
  strongly 
  narrowing 
  from 
  base 
  to 
  middle; 
  

   clypeus 
  roujided 
  at 
  apex, 
  in 
  profile 
  strongly 
  convex 
  apically, 
  labrum 
  

   narrowly 
  exposed; 
  anteima 
  very 
  slender, 
  filiform, 
  not 
  or 
  barely 
  as 
  

   long 
  as 
  body. 
  

  

  Thorax: 
  Stout; 
  pronotal 
  sinus 
  narrow, 
  spiracular 
  sclcritc 
  concealed; 
  

   mesoscutum 
  precipitous 
  anteriorly, 
  notaulices 
  obsolete; 
  scutellum 
  

   broad, 
  mnrgincd 
  nearly 
  or 
  quite 
  to 
  apex; 
  prepectornl 
  cnnna 
  distinct, 
  

   not 
  quite 
  reaching 
  anterior 
  miirgin 
  of 
  mesopleuron; 
  j)ostpectoral 
  

   carina 
  obsoletely 
  indicated 
  only 
  at 
  sides; 
  speculum 
  not 
  defined; 
  

   metapleuron 
  very 
  strongly 
  tumid; 
  propodeum 
  short, 
  prccijiitous 
  

   behind, 
  with 
  or 
  without 
  the 
  basal 
  carina, 
  basal 
  constriction 
  not 
  

   interrupted. 
  Wings 
  sparsely 
  hairy 
  except 
  apically, 
  with 
  a 
  hairless 
  

   area 
  below 
  base 
  of 
  stigma, 
  but 
  without 
  fenestra; 
  stigma 
  narrowly 
  

   triangular, 
  radius 
  at 
  about 
  basal 
  third; 
  basal 
  abscissa 
  of 
  radius 
  straight, 
  

   slender, 
  apical 
  abscissa 
  strongly 
  curved;

  narrow, 
  

   pointed 
  or
