  Haliday 
  says 
  no 
  more 
  of 
  this 
  species, 
  which, 
  like 
  

   several 
  others, 
  can 
  hardly 
  be 
  recognised 
  by 
  the 
  descrip- 
  

   tion. 
  It 
  differs 
  from 
  the 
  preceding 
  in 
  having 
  fewer 
  

   joints 
  in 
  the 
  antennae, 
  and 
  from 
  0. 
  jJarvulus 
  by 
  the 
  im- 
  

   punctate 
  furrow 
  of 
  the 
  mesopleurse.

  Wesmael 
  compares 
  this 
  var. 
  to 
  Bracon 
  orhiculator 
  , 
  Nees, 
  

   which 
  differs 
  only 
  in 
  having 
  the 
  terebra 
  as 
  long 
  as 
  the 
  two 
  last 
  

   abdominal 
  segments. 
  Eatzeburg's 
  specimen 
  (I. 
  c.) 
  belonged 
  to 
  

   this 
  var.

  This 
  species, 
  which 
  I 
  have 
  not 
  met 
  with, 
  forms 
  the 
  

   genus 
  Hypolahis, 
  Forster. 
  Wesmael's 
  description 
  was 
  

   made 
  from 
  15 
  females 
  and 
  5 
  males, 
  taken 
  near 
  Brussels 
  

   from 
  May 
  to 
  September 
  ; 
  Walker 
  captured 
  a 
  <? 
  in 
  the 
  

   London 
  district, 
  having 
  the 
  base 
  of 
  the 
  antennae 
  broadly 
  

   rufescent.
