  PRELIMINARY 
  NOTES 
  ON 
  EGYPTIAN 
  MOSQUITOS. 
  

  

  By 
  Dr. 
  L. 
  H. 
  Gough, 
  

  

  Entomologist, 
  Ministry 
  of 
  Agriculture, 
  Egypt. 
  

  

  The 
  mosquito 
  fauna 
  of 
  Egypt 
  appears 
  to 
  have 
  received 
  very 
  little 
  attention 
  

   hitherto, 
  and 
  very 
  few 
  species 
  have 
  been 
  recorded 
  from 
  this 
  country 
  up 
  to 
  the 
  present. 
  

  

  The 
  following 
  list 
  of 
  species 
  is 
  based 
  chiefly 
  on 
  the 
  collection 
  of 
  the 
  Ministry 
  of 
  

   Agriculture, 
  and 
  is 
  supplemented 
  by 
  references 
  to 
  species 
  recorded 
  by 
  other 
  observers 
  

   but 
  not 
  taken 
  by 
  us. 
  The 
  synonymy 
  used 
  is 
  that 
  proposed 
  by 
  Mr. 
  F. 
  W. 
  Edwards 
  

   in 
  his 
  papers 
  : 
  — 
  " 
  The 
  African 
  Species 
  of 
  Culex 
  and 
  allied 
  Genera 
  " 
  (Bull. 
  Ent. 
  Res., 
  

   ii, 
  p. 
  241, 
  1911) 
  ;

  Notes 
  on 
  African 
  Culicidae 
  " 
  (Bull. 
  Ent. 
  Res.,

  p. 
  47, 
  

   1913) 
  ; 
  "

  fairly 
  

   common.

   Comparison 
  of 
  a 
  series 
  of 
  over 
  200 
  specimens 
  forces 
  me 
  to 
  the 
  conclusion 
  that 
  

   all 
  the 
  above 
  names 
  must 
  be 
  sunk 
  as 
  synonyms 
  of 
  Anopheles 
  multicolor, 
  Camboulin, 
  

   which 
  is 
  a 
  most 
  variable 
  species 
  in 
  regard 
  to 
  its 
  wing 
  markings. 
  A. 
  impunctus, 
  

   A. 
  multicolor 
  and 
  A. 
  chaudoyei 
  are 
  said 
  to 
  differ 
  from 
  each 
  other 
  in 
  the 
  amount 
  of 
  

   black 
  on 
  various 
  veins 
  ; 
  A. 
  impunctus 
  being 
  the 
  species 
  with 
  the 
  least 
  and 
  A. 
  multicolor 
  

   with 
  the 
  greatest 
  extent 
  of 
  black 
  markings 
  on 
  its 
  wings. 
  These 
  characters 
  are, 
  

   however, 
  unreliable, 
  for 
  my 
  specimens 
  not 
  only 
  grade 
  quite 
  imperceptably 
  from 
  

   examples 
  with 
  hardly 
  any 
  black 
  on 
  their 
  wings 
  (A. 
  impunctus), 
  to 
  intermediate 
  

   (A. 
  chaudoyei), 
  and 
  to 
  very 
  dark- 
  winged 
  insects 
  (A. 
  multicolor) 
  ; 
  but 
  also 
  one 
  finds 
  

   single 
  specimens 
  in 
  which 
  the 
  two 
  wings 
  are 
  different, 
  the 
  characters 
  of 
  A. 
  impunctus 
  

   and 
  A. 
  chaudoyei, 
  or 
  A. 
  multicolor 
  and 
  A. 
  chaudoyei 
  being 
  combined 
  in 
  one 
  individual. 
  

   The 
  proportionate 
  sizes 
  of 
  the 
  costal 
  spots 
  also 
  vary 
  to 
  some 
  extent.
