  In

  Mr. 
  Perkins 
  did 
  not 
  have 
  the 
  

   genotype 
  before 
  him, 
  but 
  based 
  his 
  observations 
  on 
  the 
  tj'pes 
  of 
  

   Eunjophion 
  magnijicus 
  Morley 
  and 
  E. 
  superhus 
  Morley, 
  which 
  he 
  

   believed 
  properly 
  referred 
  to 
  the 
  genus.

  Orientospilus 
  Morley, 
  A 
  revision 
  of 
  tho 
  Iclineumonidae 
  based 
  on 
  the 
  collection 
  

   in 
  the 
  British 
  Museum 
  (Natural 
  History), 
  pt.

  This 
  genus 
  is 
  unkno\vn 
  to 
  me. 
  As 
  described, 
  it 
  presents 
  a 
  confusing 
  

   combination 
  of 
  characters. 
  The 
  short, 
  tumid 
  propodeum 
  overlying 
  

   the 
  hind 
  coxae 
  suggests 
  Thyreodon, 
  the 
  emarginate 
  third 
  tergite 
  

   Aglaophion, 
  and 
  the 
  fenestra 
  Enicospilus; 
  but 
  the 
  character 
  that 
  

   seems 
  to 
  ally 
  it 
  with 
  any 
  genus 
  distinguishes 
  it 
  from 
  each 
  of 
  the 
  others. 
  

  

  Mr. 
  Perkins 
  examined 
  the 
  genotype 
  and 
  sent 
  me 
  the 
  followhig 
  notes: 
  

  

  "Mandible 
  slightly 
  twisted, 
  but 
  very 
  strongly 
  tapering, 
  upper 
  

   tooth 
  much 
  longer 
  than 
  lower; 
  clypeus 
  broadly, 
  shallowly 
  emarginate 
  

   apically; 
  pronotal 
  sinus 
  broad; 
  speculum 
  not 
  set 
  off; 
  postpectoral 
  

   carina 
  absent; 
  sciitellum 
  margined; 
  basal 
  constrictioji 
  of 
  propodeum 
  

   deep 
  and 
  undivided, 
  intumescent 
  behind 
  this 
  (similar 
  to 
  Thyreodon, 
  

   ])ut 
  laterally 
  less 
  sharply 
  constricted 
  at 
  base); 
  umbo 
  present; 
  spiracles 
  

   of 
  second 
  tergite 
  (which 
  has 
  extremely 
  narrow 
  epipleura) 
  a 
  little 
  

   beyond 
  middle; 
  stigma 
  as 
  in 
  Enicospilus; 
  basal 
  abscissa 
  of 
  riidius 
  

   thickened 
  basally 
  and 
  sharply 
  curved; 
  apical 
  abscissa 
  weakly, 
  evenly 
  

   arched 
  towards 
  the 
  anterior 
  margin, 
  fenestra 
  absent; 
  abscissula 
  sharply 
  

   curved 
  at 
  base." 
  

  

  It 
  is 
  particularly 
  noteworthy 
  that 
  Perkins' 
  observation 
  on 
  the 
  lack 
  

   of 
  the 
  fenestra 
  is 
  diametrically 
  opposite 
  that 
  of 
  the 
  author 
  of 
  tho 
  

   genus, 
  who 
  described 
  the 
  fenestra 
  as 
  present 
  and 
  with 
  scleromes. 
  

  

  Enicospilvs 
  reticvlnfus 
  Cameron, 
  1899 
  (not 
  1902), 
  which 
  Morley 
  

   refers 
  to 
  this 
  genus 
  difTers 
  in 
  nearly 
  eveiy 
  chnrocter 
  from 
  the 
  original 
  

   description 
  of 
  tiie 
  gfinis. 
  As 
  I 
  liiive 
  identified 
  it 
  tiiis 
  species 
  is 
  an 
  

   Enicospilus, 
  anomalous 
  only 
  in 
  its 
  broad 
  and 
  weukly 
  twisted 
  mandibles. 
  

   It 
  is 
  closely 
  allied 
  to 
  E. 
  flavoplagiatus 
  Cusiinuin.
