  The 
  similarity 
  of 
  this 
  species 
  to 
  hebetor 
  (Say) 
  and 
  the 
  confusion 
  

   of 
  the 
  two 
  species 
  in 
  literature 
  are 
  discussed 
  under 
  hebetor. 
  

  

  Distribution. 
  — 
  This 
  species 
  apparently 
  occurs 
  throughout 
  Europe. 
  

   It 
  has 
  recently 
  been 
  introduced 
  into 
  Massachusetts 
  from 
  France, 
  as 
  

   a 
  parasite 
  of 
  the 
  imported 
  European 
  Corn-Borer, 
  Pyrausta 
  nubilalis 
  

   Huebner. 
  While 
  it 
  is 
  too 
  early 
  to 
  say 
  whether 
  or 
  not 
  it 
  has 
  become 
  

   definitely 
  established 
  in 
  the 
  United 
  States, 
  it 
  is 
  included 
  in 
  this 
  paper 
  

   because 
  of 
  the 
  probability 
  that 
  it 
  will 
  eventually 
  establish 
  itself 
  here. 
  

  

  Hosts. 
  — 
  Dioryctria 
  abietetta 
  Zinck 
  (Brischke) 
  ; 
  Pyrausta 
  nubilalis 
  

   Huebner. 
  

  

  The 
  following 
  material 
  has 
  been
