  Anopheles 
  pulcherrimus, 
  Theo. 
  

  

  Anti-malarial 
  work 
  in 
  the 
  cultivated 
  belt 
  seems 
  to 
  have 
  had 
  more 
  effect 
  on 
  this 
  

   species 
  than 
  upon 
  the 
  preceding 
  one, 
  and 
  the 
  numbers 
  have 
  been 
  greatly 
  reduced. 
  

  

  Large 
  numbers 
  of 
  larvae 
  were, 
  however, 
  found 
  in 
  pools 
  near 
  the 
  edge 
  of 
  the 
  desert 
  

   in 
  October. 
  Sometimes 
  the 
  larvae 
  of 
  this 
  species 
  and 
  those 
  of 
  A. 
  stephensi 
  occur 
  

   together 
  in 
  the 
  same 
  pool, 
  but 
  those 
  of 
  A. 
  pulcherrimus 
  usually 
  prefer 
  weed- 
  grown 
  

   stagnant 
  and 
  more 
  brackish 
  water. 
  Camps 
  near 
  the 
  desert 
  are 
  at 
  times 
  infested 
  with 
  

   large 
  numbers 
  of 
  A. 
  pulcherrimus 
  adults. 
  

  

  Anopheles 
  sinensis, 
  Wied. 
  

  

  Major 
  Christophers 
  has 
  described 
  a 
  new 
  form 
  of 
  this 
  species 
  occurring 
  in 
  

   Mesopotamia, 
  viz. 
  var. 
  mesopotamiae 
  (Indian 
  Jl. 
  Med. 
  Res. 
  hi, 
  p. 
  196). 
  The 
  

   species 
  is 
  not 
  very 
  common 
  in 
  the 
  Basrah 
  area. 
  On 
  18th 
  December 
  I 
  saw 
  it 
  

   for 
  the 
  first 
  time 
  and 
  caught 
  three 
  females 
  and 
  some 
  small 
  larvae 
  possibly 
  of 
  this 
  

   species, 
  in 
  the 
  marshes 
  on 
  the 
  left 
  bank 
  of 
  the 
  main 
  river. 
  Subsequently 
  a 
  few 
  more 
  

   were 
  taken 
  in 
  the 
  same 
  place. 
  On 
  18th 
  January 
  one 
  male 
  emerged 
  in 
  the 
  

   laboratory 
  from 
  a 
  nymph 
  collected 
  in 
  Makina 
  area. 
  Later 
  on 
  more 
  were 
  found 
  

   on 
  the 
  banks 
  of 
  a 
  creek 
  between 
  Magil 
  and 
  the 
  Euphrates. 
  

  

  Culex 
  fatigans, 
  Wied. 
  

  

  Abundant 
  throughout 
  the 
  cultivated 
  area 
  during 
  my 
  stay. 
  The 
  larvae 
  were 
  

   found 
  in 
  extraordinary 
  numbers 
  in 
  some 
  pools, 
  appearing 
  as 
  a 
  dark 
  mass 
  beneath 
  

   the 
  surface. 
  

  

  Culex 
  pipiens, 
  L. 
  

  

  Far 
  less 
  common 
  in 
  my 
  experience 
  than 
  C. 
  fatigans. 
  I 
  did 
  not 
  identify 
  any 
  larvae 
  

   of 
  this 
  species 
  until 
  January. 
  In 
  mounting 
  numbers 
  of 
  larval 
  skins 
  I 
  did 
  not 
  find 
  

   much 
  difficulty 
  in 
  separating 
  the 
  two 
  species. 
  

  

  Culex 
  modestus, 
  Fie. 
  

  

  Some 
  larvae 
  of 
  this 
  species 
  were 
  collected 
  in 
  October 
  and 
  November, 
  but 
  they 
  were 
  

   not 
  very 
  numerous. 
  In 
  one 
  case 
  they 
  were 
  found 
  in 
  a 
  pool 
  containing 
  numbers 
  of 
  

   A. 
  stephensi 
  and 
  A. 
  pulcherrimus. 
  

  

  Culex 
  fritaeniorhynchus, 
  Giles. 
  

  

  Larvae 
  were 
  found 
  in 
  October 
  and 
  November 
  in 
  Ashar 
  and 
  Makina 
  areas 
  in 
  small 
  

   numbers. 
  

  

  Culex 
  tipuliformis, 
  Theo. 
  

  

  Larvae 
  of 
  this 
  species 
  were 
  not 
  found 
  until 
  January, 
  first 
  in 
  isolated 
  pools 
  on 
  the 
  

   left 
  bank 
  of 
  the 
  main 
  river, 
  and 
  later 
  in 
  larger 
  numbers 
  in 
  Ashar 
  district. 
  

  

  Siegomyia 
  fasciafa, 
  F. 
  

  

  Very 
  few 
  specimens 
  met 
  with 
  in 
  Basrah 
  area 
  during 
  my 
  stay, 
  and 
  no 
  larvae 
  found. 
  

   On 
  23rd 
  November, 
  when 
  visiting 
  Mohommerah, 
  lower 
  down 
  the 
  main 
  river 
  on 
  the 
  

   Persian 
  side, 
  adults 
  were 
  found 
  in 
  small 
  numbers 
  in 
  a 
  building 
  on 
  the 
  river 
  bank.
