  weakly 
  sinuate 
  and 
  thickened 
  in 
  basal 
  two-tliirds; 
  abdomen

   umbo 
  absent; 
  spiracles 
  of 
  second

  The 
  genus 
  probably 
  belongs 
  in 
  the 
  EnicospiliLS 
  group, 
  because 
  of 
  

   the 
  present, 
  though 
  interrupted, 
  jostpectoral 
  carina; 
  very 
  narrow 
  and 
  

   elongate 
  stigma; 
  smuatc 
  and 
  basally 
  thickened 
  basal 
  abscissa 
  of 
  radius; 
  

   the 
  possession 
  of 
  the 
  fenestra,. 
  though 
  this 
  apparently 
  is 
  unusually 
  

   small 
  and 
  narrow; 
  and 
  the 
  lack 
  of 
  the 
  umbo 
  on 
  the 
  second 
  tergite. 
  

  

  Nearly 
  as 
  convincing 
  reason 
  for 
  placing 
  it 
  in 
  the 
  Ophion 
  group 
  is 
  

   found 
  in 
  the 
  broad 
  pronotal 
  sinus; 
  the 
  unmargined 
  scutcllum; 
  the 
  

   sharply 
  defined 
  speculum 
  ; 
  the 
  divided 
  basal 
  constriction 
  of 
  propodeum 
  ; 
  

   the 
  curved 
  abscissula; 
  and 
  the 
  location 
  of 
  the 
  second 
  tergal 
  spiracles 
  

   at 
  the 
  middle 
  of 
  the 
  tergite. 
  In 
  addition 
  to 
  the 
  characters 
  that 
  it 
  

   shares 
  with 
  the 
  Ophion 
  group 
  it 
  dillers 
  further 
  from 
  the 
  Enicospilus 
  

   group 
  by 
  the 
  peculiar 
  form 
  of 
  the 
  mandible. 
  

  

  According 
  to 
  Mr. 
  Perkins 
  the 
  American 
  species 
  described 
  in 
  Eitry- 
  

   camptus 
  Morley 
  do 
  not 
  belong 
  there, 
  E. 
  novascotine 
  being 
  an 
  Ophion. 
  

   He 
  did 
  not 
  indicate 
  in 
  liis 
  notes 
  to 
  what 
  genus 
  E.jiavipennis 
  belongs, 
  

   merely 
  stating 
  that 
  it 
  is 
  not 
  E^irycamptus 
  and 
  "differs 
  from 
  Enico- 
  

   spilus 
  as 
  follows: 
  Occipital 
  carina 
  narrowly 
  interrupted 
  centrally; 
  

   pronotal 
  sinus 
  open; 
  speculum 
  set 
  off 
  below 
  by 
  an 
  oblique 
  furrow; 
  

   postpectoral 
  carina 
  narrowly 
  interrupted 
  centrally; 
  second 
  tergite 
  

   with 
  spiracle 
  a 
  little 
  beyond 
  middle, 
  as 
  far 
  removed 
  from 
  lateral 
  margin 
  

   as 
  half 
  the 
  distance 
  between 
  the 
  spiracle 
  and 
  the 
  hind 
  margin, 
  thc^ 
  

   epipleura, 
  however, 
  narrow; 
  abdomen 
  not 
  strongly 
  compressed, 
  petiole 
  

   broader 
  than 
  deep, 
  postpetiolc 
  about 
  twice 
  as 
  broad 
  as 
  deep; 
  scutcllum 
  

   unmargined." 
  Except 
  that 
  the 
  occipital 
  and 
  postpectoral 
  carinae 
  

   are 
  present, 
  though 
  interrupted, 
  and 
  that 
  Mr. 
  Perkins 
  did 
  not 
  mention 
  

   the 
  trochanteral 
  tooth, 
  I 
  would 
  suspect 
  that 
  JI 
  a 
  vipennia 
  is 
  a 
  species 
  

   of 
  ^{ii 
  I 
  ophion.

  Dcsf'ribed 
  as 
  a 
  subgenus 
  of 
  0])hion 
  and 
  also 
  so 
  treated 
  by 
  Schmiede- 
  

   knecht, 
  this 
  wa.s 
  dilferentiated 
  from 
  the 
  typical 
  subgenus 
  only 
  by 
  the 
  

   medially 
  interrupted 
  occipital 
  carina 
  and 
  by 
  the 
  large, 
  su])quadrate 
  

   scutcllum. 
  According 
  to 
  notes 
  by 
  J. 
  F. 
  Perkins 
  the 
  genus 
  entirely 
  

   lacks 
  the 
  occipital 
  carina; 
  the 
  basal 
  constriction 
  of 
  the 
  propodeum 
  is 
  

   weakly 
  though 
  evidently 
  tlivided; 
  the 
  speculum 
  is 
  strongly 
  convex, 
  

   but 
  not 
  margined 
  anteriorly 
  by 
  a 
  disfinci 
  groove; 
  the 
  first 
  recurrent 
  

   vein 
  is 
  strongly 
  converg(!nt 
  with 
  the 
  basal; 
  and 
  the 
  ncrvellus 
  is 
  very 
  

   long. 
  

  

  These 
  characters 
  seem 
  to 
  indicate 
  a 
  relationship 
  to 
  Stanropodonus 
  

   and 
  Aulophion, 
  and 
  1 
  should 
  not 
  be 
  surprised 
  if 
  it 
  is 
  reully 
  a 
  synonym
