  specimen 
  only.

  This 
  is 
  one 
  of 
  the 
  commonest 
  Culicine 
  mosquitos 
  in 
  our 
  collection, 
  and 
  as 
  Linn 
  6*3 
  

  

  description 
  of 
  Culex 
  aegypti 
  fits 
  it 
  very 
  well, 
  there 
  can 
  remain 
  very 
  little 
  doubt 
  

  

  that 
  it 
  is 
  really 
  the 
  same 
  species, 
  especially 
  as 
  there 
  appears 
  to 
  be 
  no 
  other 
  common 
  

  

  Egyptian 
  species 
  fitting 
  the 
  description. 
  It 
  breeds 
  in 
  brackish 
  as 
  well 
  as 
  fresh 
  water. 
  

  

  Localities 
  : 
  Cairo, 
  Meadi, 
  Gizeh, 
  Helouan, 
  Baharia 
  Oasis, 
  Siwa 
  Oasis, 
  Kharga 
  Oasis. 
  

  

  10. 
  Theobaldia 
  spathipalpis 
  (Eondani). 
  

  

  Localities 
  : 
  Cairo, 
  Meadi, 
  Imbaba, 
  Kharga 
  Oasis 
  ; 
  chiefly 
  in 
  winter. 
  

  

  11. 
  Culex 
  quasigelidus, 
  Theobald. 
  

   Locality 
  : 
  Meadi 
  ; 
  rare. 
  

  

  12. 
  Culex 
  (?) 
  invidiosus, 
  Theobald. 
  

  

  I 
  have 
  provisionally 
  identified 
  a 
  small 
  Culex 
  under 
  this 
  name, 
  but 
  the 
  specimens 
  

   appear 
  to 
  me 
  to 
  fit 
  the 
  description 
  of 
  Culex 
  guiarti, 
  Theobald, 
  equally 
  well. 
  The 
  

   apical 
  dark 
  banding 
  of 
  the 
  venter 
  of 
  the 
  abdomen, 
  or 
  its 
  absence, 
  used 
  by 
  Edwards 
  

   in 
  his 
  key, 
  is 
  not 
  a 
  constant 
  character, 
  the 
  banding 
  is 
  quite 
  distinct 
  in 
  some 
  of 
  my 
  

   specimens 
  and 
  absent 
  in 
  others. 
  It 
  breeds 
  in 
  fresh 
  water, 
  and 
  is 
  quite 
  common. 
  

  

  Localities 
  : 
  Meadi, 
  Cairo, 
  Dessuk, 
  Port 
  Said, 
  Shebin 
  El 
  Kom, 
  Damietta. 
  

  

  18. 
  Culex 
  theileri, 
  Theobald. 
  

   Locality 
  : 
  Kharga 
  Oasis 
  ; 
  rare. 
  

  

  14. 
  Culex 
  pallidocephalus, 
  Theobald. 
  

  

  Localities 
  : 
  Meadi, 
  Fayoum, 
  Shebin 
  El 
  Kom, 
  Siwa 
  Oasis 
  ; 
  common. 
  

  

  15. 
  Culex 
  quasimodestus, 
  Theobald. 
  

  

  Localities 
  : 
  Meadi, 
  Fayoum, 
  Bahria 
  Oasis 
  ; 
  not 
  common. 
  

  

  16. 
  Culex 
  fatigans, 
  Weidemann. 
  

  

  Localities 
  : 
  Cairo, 
  Giza, 
  Meadi 
  ; 
  common. 
  

  

  17.

  Linne. 
  

  

  Localities 
  : 
  Cairo, 
  Meadi, 
  Giza,

  Oasis. 
  

  

  This 
  is 
  the 
  commonest 
  Culicine 
  mosquito 
  near 
  Cairo. 
  

  

  My 
  thanks 
  are 
  due 
  to 
  Mr. 
  J. 
  Bitter 
  and 
  Capt. 
  Thomson 
  of 
  the 
  Public 
  Health 
  

   Department 
  for 
  having 
  collected 
  very 
  many 
  of 
  the 
  mosquitos 
  recorded 
  here, 
  

   including 
  all 
  the 
  specimens 
  taken 
  in 
  the 
  Oases, 
  and 
  most 
  of 
  those 
  collected 
  elsewhere 
  

   than 
  at 
  Cairo, 
  Meadi, 
  Giza, 
  Helouan 
  and 
  the 
  Fayoum.
