  SUMMARY 
  OF 
  Prey. 
  

  

  spend 
  tlieir 
  lives 
  resting 
  on 
  water-plants 
  and 
  low 
  bushes, 
  or 
  

   in 
  taking 
  short 
  flights 
  over 
  tlie 
  surface 
  of 
  the 
  water. 
  It 
  is 
  

   possible, 
  therefore, 
  that 
  this 
  great 
  difference 
  in 
  the 
  mode 
  of 
  

   life 
  may 
  be 
  accompanied 
  by 
  a 
  difference 
  in 
  feeding-habits. 
  

  

  I 
  cannot 
  discover 
  tliat 
  particular 
  species 
  of 
  Dragonflies 
  

   show 
  any 
  marked 
  preference 
  for 
  particuhar 
  species 
  of 
  prey. 
  

   Tortrix 
  viridana 
  appears 
  four 
  times 
  in 
  the 
  British 
  records 
  

   cited 
  above, 
  but 
  only 
  twice 
  in 
  connection 
  with 
  the 
  same 
  

   species 
  of 
  Dragonfly, 
  and 
  only 
  three 
  times 
  in 
  association 
  with 
  

   members 
  of 
  the 
  same 
  family 
  ; 
  moreover, 
  this 
  pretty 
  little 
  

   moth 
  occurs 
  about 
  oak-trees 
  in 
  swarms 
  during 
  June 
  and 
  

   July. 
  Six 
  records 
  of 
  tsetse-flies 
  from 
  Uganda 
  are 
  distributed 
  

   equally 
  among 
  three 
  not 
  uncommon 
  species 
  of 
  CHlonata,
