  Despite 
  the 
  stout 
  form, 
  especially 
  of 
  the 
  abdomen, 
  and 
  the 
  entire 
  

   lack 
  of 
  the 
  fenestra, 
  this 
  anomalous 
  Hawaiian 
  genus 
  is 
  more 
  closely 
  

   allied 
  to 
  Enicospilus 
  than 
  to 
  Ophion 
  in 
  most 
  of 
  the 
  important 
  char- 
  

   acters 
  distinguishing 
  those 
  two 
  genera. 
  It 
  is 
  perhaps 
  significant 
  that 
  

   neither 
  Ophion 
  nor 
  any 
  genus 
  closely 
  allied 
  to 
  it 
  occurs 
  in 
  the 
  endemic 
  

   fauna 
  of 
  the 
  Hawaiian 
  Islands, 
  whereas 
  Enicospilus 
  is 
  represented 
  by 
  

   numero'13 
  species. 
  

  

  Head: 
  Thick; 
  temples 
  strongly 
  convex 
  but 
  considerably 
  narrower 
  

   than 
  eyes; 
  occiput 
  rather 
  deeply 
  concave, 
  carina 
  complete; 
  eyes 
  and 
  

   ocelli 
  small, 
  malar 
  space 
  and 
  ocellocular 
  line 
  long; 
  eyes 
  broadly 
  emargi- 
  

   nate; 
  face 
  and 
  frons 
  broad, 
  about 
  equal 
  in 
  breadth; 
  stemmaticum 
  

   distinctly 
  set 
  off 
  and 
  somewhat 
  elevated; 
  clypeus 
  narrow, 
  apex 
  

   broadly 
  rounded, 
  labrum 
  narrowly 
  exposed; 
  mandible 
  much 
  twisted, 
  

   abruptly 
  narrowed 
  from 
  base; 
  antenna 
  slender, 
  filiform. 
  

  

  Thorax: 
  Short 
  and 
  stout; 
  pronotal 
  sinus 
  narrow, 
  spii-acular 
  sclerite 
  

   concealed; 
  mesoscutum 
  in 
  profile 
  moderately 
  convex, 
  notaulices 
  

   obsolete; 
  scutellum 
  margined 
  to 
  top 
  of 
  the 
  abrupt 
  apical 
  slope; 
  

   speculum 
  not 
  at 
  all 
  defined; 
  prepectoral 
  carina 
  incomplete 
  above; 
  

   postpectoral 
  carina 
  complete; 
  propodeum 
  very 
  short, 
  precipitous 
  

   behind, 
  not 
  at 
  all 
  overlapping 
  hind 
  coxae, 
  only 
  basal 
  carina 
  present, 
  

   basal 
  constriction 
  not 
  interrupted. 
  Wings 
  with 
  dense 
  setae 
  and 
  with- 
  

   out 
  fenestra 
  or 
  hairless 
  area; 
  stigma 
  narrowly 
  triangular, 
  radius 
  at 
  

   about 
  basal 
  third 
  ; 
  basal 
  abscissa 
  of 
  radius 
  straight 
  and 
  slender, 
  apical 
  

   abscissa 
  curving 
  strongly 
  from 
  base; 
  second 
  discoidal 
  cell 
  narrow, 
  

   nearly 
  or 
  quite 
  pointed

  Townes 
  has 
  synonymized 
  this 
  genus 
  with 
  Enicospilus. 
  I 
  exclude 
  from 
  Enicospilus 
  all 
  

   species 
  lacking 
  the 
  fenestra. 
  This 
  and 
  the 
  unusually 
  stout 
  habitus 
  are, 
  I 
  think, 
  sufficient 
  to 
  justify 
  the 
  reten- 
  

   tion 
  of 
  Banchogastra,
