﻿WITH 
  NOTES 
  ON 
  THE 
  GENITALIA 
  OF 
  SOME 
  AFEICAN 
  CULEX.

  Culex 
  simpsoni, 
  Theo. 
  

  

  Although 
  this 
  species 
  has 
  really 
  little 
  resemblance 
  to 
  C. 
  andersoni 
  the 
  hypopygia 
  

   of 
  the 
  two 
  are 
  very 
  similar, 
  the 
  chief 
  differences 
  being 
  that 
  in 
  C. 
  simpsoni 
  (fig. 
  3) 
  

   the 
  unci 
  are 
  more 
  sharply 
  pointed 
  and 
  the 
  first 
  division 
  of 
  the 
  harpagones 
  is 
  differently 
  

   toothed. 
  Culex 
  simpsoni 
  is 
  much 
  smaller 
  than 
  any 
  of 
  the 
  members 
  of 
  the 
  

   pallidocephalus 
  group 
  (pallidocephalus, 
  mirificus, 
  trifilatus, 
  andersoni) 
  and 
  has 
  the 
  

   cross-veins 
  more 
  widely 
  separated.

  Culex 
  neavei, 
  Theo. 
  

  

  This 
  was 
  previously 
  sunk 
  by 
  the 
  writer 
  as 
  synonymous 
  with 
  C. 
  guiarti, 
  Blanch., 
  

   but 
  it 
  now 
  appears 
  that 
  the 
  two 
  must 
  be 
  kept 
  separate, 
  although 
  no
