  The 
  banding 
  of 
  the 
  palps 
  seems 
  to 
  be 
  the 
  only 
  difference 
  between 
  

   these 
  two 
  mosquitos 
  ; 
  in 
  punctulatus 
  the 
  arrangement 
  of 
  the 
  bands 
  from 
  tip 
  to 
  base 
  

   is 
  : 
  white 
  tip, 
  black 
  band, 
  broad 
  white 
  band, 
  black

  the

  are

  This 
  species 
  was 
  found 
  inhabiting 
  the 
  estate 
  (A) 
  hospital 
  and 
  one 
  of 
  the 
  houses 
  

   near 
  the 
  Membakut 
  swamp. 
  About 
  30 
  specimens 
  were 
  taken, 
  but 
  no 
  larvae 
  were 
  

   found. 
  The 
  time 
  of 
  capture 
  was 
  April, 
  May 
  and 
  July, 
  1913, 
  females 
  predomi- 
  

   nating.

  Two 
  specimens 
  only 
  (both 
  females) 
  were 
  found 
  ; 
  one 
  in 
  a 
  coolie 
  line 
  on 
  a 
  coconut 
  

   estate 
  at 
  Kuala 
  Lama, 
  about 
  six 
  miles 
  west 
  of 
  Membakut, 
  in 
  December 
  1912 
  ; 
  and 
  

   the 
  other 
  in 
  one 
  of 
  the 
  houses 
  on 
  estate 
  (D) 
  at 
  Papar, 
  in 
  April 
  1913. 
  

  

  Sixteen 
  cases 
  of 
  subtertian 
  malaria 
  had 
  been 
  admitted 
  from 
  the 
  line 
  in 
  question 
  

   and 
  this 
  species 
  was 
  the 
  only 
  one 
  observed 
  in 
  the 
  neighbourhood. 
  No 
  larvae 
  were 
  

   found.

  A 
  careful 
  comparison 
  of 
  ten 
  females 
  and 
  two 
  males 
  with 
  Leicester's 
  types 
  in 
  the 
  

   British 
  Museum 
  makes 
  it 
  clear 
  that 
  the 
  specimens 
  taken 
  in 
  Borneo 
  belong 
  to 
  the 
  

   same 
  species. 
  The 
  points 
  I 
  would 
  emphasise 
  as 
  being 
  very 
  constant 
  and 
  sufficiently 
  

   differentiating 
  it 
  from 
  the 
  species 
  it 
  most 
  resembles, 
  namely 
  A. 
  sinensis 
  and 
  

   A. 
  umbrosus, 
  are 
  as 
  follows 
  : 
  the 
  palps 
  have 
  dirty 
  grey 
  tips 
  ; 
  in 
  the 
  wings 
  the 
  middle 
  

   spot 
  always 
  extends 
  on 
  to 
  the 
  first 
  longitudinal 
  vein 
  ; 
  yellow 
  spot 
  on 
  first 
  longitudinal 
  

   vein 
  always 
  confined 
  to 
  this 
  at 
  the 
  junction 
  of 
  inner 
  third 
  with 
  outer 
  two- 
  thirds 
  of 
  

   wing 
  ; 
  yellow 
  spot 
  on 
  fringe 
  between 
  lower 
  branch 
  of 
  second 
  longitudinal 
  vein 
  and 
  

   third 
  longitudinal 
  vein 
  ; 
  predominance 
  of 
  light 
  scales 
  ; 
  absence 
  of 
  apical 
  ventral 
  tuft 
  

   on 
  the 
  abdomen. 
  I 
  should 
  add 
  that 
  in 
  two 
  out 
  of 
  the 
  ten 
  females 
  there 
  was 
  in 
  the 
  

   palps 
  a 
  faint 
  suggestion 
  in 
  one 
  case 
  of 
  one 
  additional 
  ring, 
  and 
  in 
  the 
  other 
  of 
  two 
  

   additional 
  rings. 
  In 
  the 
  male 
  the 
  expanded 
  portion 
  of 
  the 
  palp 
  is 
  dirty 
  grey, 
  with 
  

   a 
  light 
  brown 
  thin 
  band 
  in 
  the 
  centre.f 
  In 
  spite 
  of 
  these 
  small 
  deviations 
  the 
  other 
  

   characters 
  were 
  constant. 
  

  

  Adult 
  specimens 
  were 
  taken 
  in 
  the 
  houses 
  on 
  estate 
  (A) 
  and 
  in 
  the 
  estate 
  (A) 
  

   hospital 
  ; 
  one 
  specimen 
  came 
  from 
  the 
  Rest 
  House 
  in 
  Jesselton. 
  It 
  is 
  not 
  a 
  common 
  

   species 
  and 
  only 
  about 
  twenty 
  specimens 
  were 
  obtained, 
  females 
  predominating. 
  

   One 
  female 
  was 
  bred 
  from 
  a 
  larva 
  found 
  in 
  the 
  Membakut 
  swamp. 
  No 
  note 
  was 
  

   made 
  as 
  to 
  the 
  characters 
  of 
  the 
  larva.
