  description 
  of 
  hebetor, 
  that 
  there 
  can 
  be 
  no 
  reasonable 
  doubt 
  that 
  

   Say 
  and 
  Ashmead 
  were 
  dealing 
  with 
  the 
  same 
  species. 
  In 
  fact, 
  

   Ashmead 
  determined 
  some 
  specimens 
  of 
  this 
  species 
  in 
  the 
  National 
  

   Museum 
  as 
  hebetor 
  Say, 
  although 
  failing 
  to 
  recognize 
  the 
  identity 
  

   of 
  juglandis 
  with 
  this 
  material. 
  The 
  combination 
  of 
  characters 
  

   ascribed 
  to 
  hebetor 
  by 
  Say 
  is 
  found 
  nowhere 
  else 
  in 
  the 
  Braconidae, 
  

   and 
  after 
  allowing 
  for 
  the 
  wide 
  range 
  of 
  variation 
  occurring 
  in 
  the 
  

   species, 
  will 
  be 
  found 
  to 
  agree 
  nicely 
  with 
  juglandis. 
  Bracon 
  dor- 
  

   sator 
  Say 
  is 
  also, 
  without 
  question, 
  this 
  species; 
  and 
  a 
  study 
  of 
  the 
  

   type 
  of 
  Habrobracon 
  beneftcientior 
  Viereck 
  shows 
  this 
  species, 
  too, 
  

   to 
  be 
  identical 
  with 
  hebetor 
  Say. 
  References 
  in 
  literature 
  to 
  Bracon 
  

   or

  brevicornis,

   Mediterranean 
  flour

  The 
  females 
  of 
  hebetor 
  are 
  readily 
  distinguished 
  from 
  those 
  of 
  

   brevicornis 
  by 
  the 
  antennae, 
  which 
  are 
  13 
  to 
  15-segmented 
  in 
  the 
  

   former, 
  and 
  17 
  to 
  19-segmented 
  in 
  the 
  latter. 
  The 
  males 
  of 
  the 
  two 
  

   species 
  are 
  much 
  more 
  difficult 
  to 
  distinguish, 
  but 
  the 
  characters 
  

   mentioned 
  in 
  the 
  key 
  will 
  nearly 
  always 
  separate 
  them. 
  The 
  abdo- 
  

   men 
  in 
  hebetor 
  is 
  almost 
  invariably 
  somewhat 
  smoother, 
  with 
  the 
  

   punctures 
  less 
  distinct, 
  than 
  in 
  brevicornis. 
  In 
  color 
  this 
  species 
  is 
  

   exceedingly 
  inconstant. 
  

  

  Distribution. 
  — 
  Apparently 
  occurs 
  throughout 
  the 
  world, 
  wher- 
  

   ever 
  its 
  hosts, 
  particularly 
  the 
  flour 
  and 
  meal 
  moths, 
  are 
  present.
