  A 
  NEW 
  ANOPHELINE 
  MOSQUITO 
  FROM 
  SUMATRA. 
  

  

  By

  T. 
  Stanton, 
  

  

  Institute 
  for 
  Medical 
  Research,

  Lumpur, 
  

  

  Federated 
  Malay 
  States, 
  

  

  In 
  the 
  course 
  of 
  an 
  investigation 
  of 
  malaria 
  in 
  the 
  Lampongs, 
  a 
  district 
  of 
  South 
  

   Sumatra, 
  in 
  the 
  months 
  of 
  May 
  and 
  June 
  1914, 
  Dr. 
  SchiirTner 
  captured 
  a 
  large 
  

   number 
  of 
  Anopheline 
  mosquitos, 
  among 
  them 
  a 
  series 
  of 
  specimens 
  of 
  a 
  species 
  

   which 
  he 
  recognised 
  as 
  new 
  to 
  Sumatra. 
  

  

  The 
  larva 
  of 
  this 
  mosquito 
  has 
  not 
  yet 
  been 
  identified 
  ; 
  should 
  it 
  prove 
  on 
  

   examination 
  that 
  it 
  is 
  of 
  the 
  fuliginosus 
  type, 
  I 
  should 
  prefer 
  to 
  regard 
  the 
  mosquito 
  

   here 
  described 
  as 
  a 
  variety 
  of 
  that 
  species. 
  From 
  the 
  characters 
  of 
  the 
  adult 
  insect, 
  

   however, 
  I 
  think 
  the 
  larva 
  will 
  be 
  found 
  to 
  be 
  clearly 
  distinct, 
  and 
  I 
  have 
  assigned 
  

   the 
  name, 
  schuffneri, 
  to 
  the 
  species 
  in 
  honour 
  of 
  its 
  discoverer. 
  

  

  The 
  following 
  description 
  has 
  been 
  drawn 
  up 
  from 
  an 
  examination 
  of 
  six 
  females, 
  

   no 
  male 
  of 
  the 
  species 
  having 
  so 
  far 
  been 
  taken.
