﻿NOTES 
  ON 
  AFRICAN 
  CHALCIDOIDEA 
  —

  measurements 
  of 
  tarsal 
  joints 
  have 
  been 
  taken 
  along 
  the 
  dorsal 
  edge, 
  and 
  the 
  fourth 
  

   joint 
  reckoned 
  as 
  extending 
  to 
  about 
  the 
  middle 
  of 
  the 
  empodium, 
  i.e. 
  x 
  to 
  the 
  bend 
  

   of 
  the 
  claw, 
  as 
  this 
  is 
  the 
  point 
  at 
  which 
  the 
  eye 
  naturally 
  rests 
  in 
  comparing 
  the 
  

   fourth 
  with 
  the 
  other 
  joints. 
  

  

  In 
  describing 
  P. 
  neavei, 
  sp. 
  n., 
  many 
  details 
  of 
  generic 
  value 
  only 
  have 
  been 
  men- 
  

   tioned 
  ; 
  in 
  the 
  others, 
  comparative 
  features 
  mainly 
  have 
  been 
  emphasised. 
  

  

  The 
  available 
  evidence 
  suggests 
  very 
  strongly 
  that 
  the 
  species 
  of 
  Pleurotropis 
  

   will 
  prove 
  to 
  be 
  hyperparasites 
  upon 
  other 
  parasitic 
  Hymenopfcera 
  ; 
  and 
  if 
  this 
  be 
  so, 
  

   they 
  must 
  be 
  regarded 
  in 
  many 
  cases 
  as 
  noxious 
  insects.
