  In 
  Thomson's 
  classic 
  revision 
  of 
  some 
  

   European 
  species 
  of 
  tliis 
  genus 
  this 
  species 
  would 
  appear 
  to 
  come 
  

   nearest 
  to 
  his 
  group 
  ee, 
  from 
  wliich 
  it 
  can 
  readily 
  be 
  distinguished 
  by 
  

   the 
  nervulus, 
  wliich 
  is 
  an 
  tef 
  ureal. 
  Stramineous; 
  apical 
  half 
  of 
  

   antemise

  bro^vnisll, 
  face 
  punctured, 
  mandibles 
  with 
  brown 
  tips; 
  

   wings 
  including 
  stigma 
  concolorous 
  and 
  yellowish 
  excepting 
  the 
  veins 
  

   which 
  are 
  brownish, 
  nervulus 
  shorter 
  than 
  the 
  distance 
  between 
  it 
  and 
  

   the 
  basal 
  vein, 
  areolet 
  quadrangular 
  and 
  almost 
  forming 
  a 
  right- 
  

   angled 
  triangle; 
  hind 
  tibise 
  nearly 
  as 
  broad 
  as 
  the 
  hind 
  femora; 
  pro- 
  

   podeum 
  blackish 
  above, 
  areola 
  hexagonal, 
  narrower 
  at 
  base 
  tRan 
  at 
  

   apex, 
  the 
  costulse 
  joining 
  the 
  former 
  nearer 
  the 
  apex 
  than 
  the 
  base; 
  

   petiole 
  as 
  long 
  as 
  the 
  post-petiole 
  and 
  the 
  lateral 
  margins 
  of 
  the 
  apical 
  

   half 
  blackish, 
  lateral 
  margins 
  of 
  the 
  second, 
  dorsal, 
  abdominal 
  seg- 
  

   ment 
  blackish: 
  sheaths 
  of 
  the

  This 
  is 
  a 
  hyperparasite 
  and 
  probably 
  parasitic 
  on 
  Apanteles 
  plusise 
  

   Viereck 
  or 
  on 
  a 
  Meteorus. 
  

  

  MESOSTENIMORPHA, 
  new 
  genus. 
  

  

  Habitus 
  as 
  in 
  Crypturopsis 
  Ashmead, 
  with 
  which 
  in 
  the 
  main 
  it 
  

   agrees, 
  except 
  in 
  the 
  areolet, 
  which 
  is 
  as 
  in 
  Cryptus 
  Fabricius, 
  in 
  the 
  

   presence 
  of 
  an 
  apical 
  transverse 
  carina, 
  in 
  addition 
  to 
  the 
  propodeal 
  

   spines 
  and 
  in 
  having 
  the 
  median 
  longitudinal 
  carinas 
  feebly 
  developed.

  new 
  subgenus. 
  

  

  Related 
  to 
  Pezomachus 
  Gravcnhorst, 
  from 
  which 
  it 
  can 
  be 
  separated 
  

   by 
  the 
  mesonotum 
  and 
  propoduem 
  being 
  separated 
  by 
  an 
  antero- 
  

   posteriorly 
  long 
  furrow, 
  at 
  the 
  bottom 
  of 
  which 
  is 
  a 
  suggestion 
  of 
  a 
  

   scutel, 
  the 
  scutel 
  being 
  as 
  long 
  dorsally 
  as 
  the 
  pronotum.

   spiraculus 
  Strickland, 
  from 
  which 
  it 
  may 
  be 
  distinguished 
  especially 
  

   by 
  the 
  slender 
  antennae, 
  which 
  are 
  rather 
  brownish 
  stramineous 
  except 
  

   at
