  About 
  35 
  specimens 
  of 
  this 
  species 
  were 
  found 
  in 
  the 
  estate 
  (A) 
  hospital, 
  a 
  building 
  

   situated 
  150 
  yards 
  from 
  the 
  jungle 
  and 
  200 
  yards 
  from 
  the 
  Membakut 
  swamp. 
  

   Female 
  specimens 
  predominated. 
  No 
  larvae 
  were 
  found, 
  and 
  the 
  hospital 
  was 
  the 
  

   only 
  building 
  in 
  which 
  the 
  species 
  was 
  taken. 
  Five 
  specimens 
  were 
  dissected, 
  but 
  

   none 
  was 
  found 
  infected. 
  January, 
  June, 
  April 
  and 
  December, 
  1913, 
  were 
  the 
  

   months 
  in 
  which 
  they 
  were 
  taken. 
  The 
  description 
  is 
  based 
  on 
  four 
  females 
  and 
  

   two 
  males. 
  

  

  The 
  types 
  have 
  been 
  deposited 
  in 
  the 
  British 
  Museum.

  other

  This 
  is 
  by 
  far 
  the 
  commonest 
  Anopheline 
  found 
  in 
  the 
  district.

   bred
