  Marshall's 
  Monograph 
  of 
  

  

  refers 
  to 
  O. 
  jmllidipes, 
  Wesm., 
  a 
  parasite 
  which 
  he 
  reared 
  

   from 
  Tephritis 
  onopordinis, 
  Fall. 
  ; 
  but 
  the 
  description 
  of 
  

   the 
  parasite 
  is 
  not 
  technical 
  enough 
  to 
  lead 
  to 
  its 
  veri- 
  

   fication. 
  The 
  nervures 
  and 
  stigma 
  are 
  described 
  as 
  

   blackish, 
  and 
  the 
  recurrent 
  nervure 
  as 
  interstitial, 
  — 
  

   characters 
  not 
  applicable 
  to 
  the 
  present 
  species. 
  We 
  

   are 
  informed 
  by 
  Eatzeburg 
  (I.e.) 
  that 
  Bouche 
  bred 
  

   O. 
  pallidipes 
  from 
  Tortrix 
  rosana, 
  L. 
  ; 
  while, 
  according 
  

   to 
  Boie, 
  it 
  was 
  also 
  bred 
  by 
  Bouche 
  from 
  a 
  dipteron 
  

   named 
  by 
  the 
  latter 
  Anthomyia 
  rumicis, 
  perhaps 
  a 
  

   Pegomyia, 
  but 
  which 
  can 
  hardly 
  now 
  be 
  identified.

  Originally 
  described 
  by 
  Wesmael 
  from 
  a 
  ? 
  with 
  broken 
  

   antennae 
  ; 
  Haliday 
  possessed 
  only 
  two 
  specimens 
  from 
  

   North 
  Ireland 
  and 
  England. 
  I 
  have 
  taken 
  5 
  in 
  Essex, 
  

   Monmouthshire, 
  and 
  Cornwall. 
  The 
  species 
  is 
  more 
  

   easily 
  identified 
  than 
  most 
  of 
  the 
  preceding 
  : 
  it 
  is 
  strange 
  

   that 
  Wesmael 
  should 
  compare 
  it 
  with 
  his 
  0. 
  maculipes 
  

   and 
  ochrogasfcr 
  (spp. 
  19, 
  17), 
  both 
  of 
  which 
  are 
  obviously 
  

   different 
  in 
  structure, 
  colour, 
  and 
  size.
