  as 
  to 
  previous 
  acts 
  of 
  oviposition 
  on 
  the 
  part 
  of 
  the 
  captured 
  females, 
  and 
  partly 
  by 
  

   reason 
  of 
  their 
  battered 
  condition 
  towards 
  the 
  end 
  of 
  long 
  confinement, 
  whereby 
  the 
  

   oviposition 
  of 
  more 
  batches 
  of 
  ova 
  may 
  well 
  have 
  been 
  prejudiced. 
  The 
  first 
  of 
  these 
  

   difficulties, 
  at 
  all 
  events, 
  the 
  writer 
  saw 
  no 
  means 
  of 
  overcoming, 
  since 
  pairing 
  

   between 
  the 
  insects 
  in 
  captivity 
  will 
  not 
  take 
  place, 
  probably 
  because 
  the 
  males 
  are 
  

   unable 
  to 
  execute 
  the 
  complicated 
  dances 
  which 
  precede 
  coupling. 
  The 
  following 
  

   are 
  the 
  data 
  : 
  — 
  

  

  Anopheles 
  hyrcanus.
