  Eatzeburg 
  [I.

  briefly 
  mentions 
  an 
  

   Opius 
  paradoxus, 
  bred 
  by 
  Bouche 
  from 
  the 
  maggot 
  of 
  

   Pegomyia 
  bicolor, 
  Wied., 
  which 
  had 
  the 
  wings 
  of 
  Eury- 
  

   tenes, 
  except 
  that 
  the 
  2d 
  and 
  3d 
  cubital 
  areolets 
  were 
  not 
  

   separated. 
  The 
  2d 
  intercubital 
  nervure 
  is 
  subobsolete 
  

   in 
  nearly 
  all 
  the 
  Opiids, 
  and 
  I 
  presume 
  Eatzeburg's 
  

   insect 
  was 
  the 
  present 
  species.
