  logryon 
  Ashmead, 
  which 
  allegedly 
  differ 
  only 
  in 
  having 
  the 
  parapsidal 
  

   grooves 
  com'olote 
  or 
  incomplete 
  (sometimes 
  absent), 
  cannot 
  be 
  sepa- 
  

   rated. 
  Several 
  species 
  are 
  described 
  in 
  Mr. 
  Dodd's 
  paper 
  which 
  have 
  

   the 
  parapsidal 
  grooves 
  present 
  in 
  the 
  male 
  but 
  absent 
  in 
  the 
  female. 
  

   I 
  have 
  found 
  that 
  it 
  is 
  sometimes 
  difficult 
  to 
  determine 
  whether 
  the 
  

   parapsidal 
  grooves 
  are 
  complete 
  or 
  even 
  whether 
  they 
  are 
  present 
  

   at 
  all. 
  

  

  More 
  recently, 
  G. 
  E. 
  J. 
  Nixon, 
  of 
  the 
  British 
  Museum, 
  has 
  written 
  

   a 
  paper 
  on 
  African 
  Teleasinae 
  ' 
  in 
  which 
  he 
  describes, 
  with 
  accom- 
  

   panying 
  keys 
  and 
  numerous 
  excellent 
  illustrations, 
  3 
  new 
  species 
  of 
  

   Trimorus, 
  24 
  new 
  species 
  of 
  Hojdogryon, 
  and 
  1 
  new 
  genus 
  (with 
  3 
  new 
  

   species), 
  all 
  from 
  South 
  Africa, 
  except 
  one 
  species 
  from 
  Kenya 
  and 
  

   one 
  from 
  Nyassaland. 
  His 
  new 
  genus 
  Macrogryon 
  may 
  be 
  synony- 
  

   mous 
  with 
  Gryonoides 
  Dodd 
  (1919), 
  differing, 
  as 
  far 
  as 
  T 
  can 
  determine 
  

   from 
  the 
  descriptions, 
  only 
  in 
  the 
  larger 
  size 
  of 
  its 
  representatives 
  

   and 
  in 
  having 
  the 
  eyes 
  pubescent. 
  

  

  Little 
  is 
  known 
  of 
  the 
  habits 
  of 
  the 
  wasps 
  belonging 
  to 
  the 
  sub- 
  

   family 
  Teleasinae. 
  In 
  Europe 
  one 
  species 
  of 
  Trimorus 
  and 
  one 
  of 
  

   Teleas 
  are 
  parasites 
  of 
  a 
  species 
  of 
  Scolytus; 
  one 
  species 
  of 
  Trimorus 
  

   and 
  one 
  of 
  Teleas 
  are 
  guests 
  of 
  Lasius 
  fuliginosus 
  (Latreille) 
  ; 
  one 
  

   species 
  of 
  Paragryon 
  is 
  a 
  guest 
  of 
  Lasius 
  flavus 
  (Fabricius) 
  ; 
  and 
  one 
  

   species 
  of 
  Trimorus 
  was 
  reared 
  from 
  the 
  gall 
  of 
  Rhabdophaga 
  rosaria 
  

   Loew. 
  In 
  the 
  United 
  States 
  Trimorus 
  bethunei 
  (Sanders) 
  is 
  recorded 
  

   as 
  a 
  guest 
  of 
  Formica 
  subrufa 
  Roger, 
  and 
  Trimorus 
  caraborum 
  (Riley) 
  

   is 
  recorded 
  as 
  being 
  parasitic 
  in 
  the 
  eggs 
  of 
  the 
  carabid 
  beetle 
  Chlaenius 
  

   impunctifrons 
  Say.
