  This 
  species 
  was 
  first 
  described 
  by 
  Donitz 
  from 
  specimens 
  taken 
  in 
  Sumatra. 
  About 
  

   the 
  same 
  time 
  Theobald 
  had 
  prepared 
  from 
  Malayan 
  specimens 
  the 
  description 
  of 
  an 
  

   Anopheline 
  species 
  for 
  which 
  he 
  proposed 
  the 
  name 
  ocellatus, 
  but 
  recognising 
  that 
  

   Donitz' 
  kochii 
  and 
  his 
  own 
  ocellatus 
  were 
  the 
  same 
  species 
  he 
  published 
  his 
  description 
  

   as 
  that 
  of 
  Anopheles 
  kochii, 
  Donitz. 
  

  

  Some 
  years 
  later, 
  Major 
  James, 
  I.M.S., 
  examined 
  a 
  specimen 
  from 
  the 
  Indian 
  

   Museum, 
  Calcutta, 
  labelled 
  " 
  Cellia 
  kochii" 
  but 
  which 
  he 
  recognised 
  as 
  differing 
  from 
  

   other 
  species 
  in 
  the 
  genus 
  Cellia 
  in 
  the 
  position 
  of 
  the 
  tufts 
  of 
  abdominal 
  scales. 
  Mr. 
  

   Theobald 
  to 
  whom 
  the 
  specimen 
  was 
  sent 
  for 
  examination 
  was 
  of 
  opinion 
  that 
  it 
  

   represented 
  a 
  new 
  Anopheline 
  genus 
  ; 
  it 
  was 
  accordingly 
  described 
  by 
  James 
  under 
  

   the 
  name 
  Christophersia 
  halli. 
  The 
  peculiar 
  character 
  of 
  the 
  scale-tufts 
  in 
  kochi 
  

   had 
  already 
  been 
  noted 
  by 
  Donitz, 
  who, 
  referring 
  to 
  the 
  abdominal 
  scale-tufts 
  in 
  the 
  

   species 
  pharoensis 
  and 
  squamosus, 
  wrote 
  (Zeit. 
  fur 
  Hygiene, 
  xli, 
  1902) 
  " 
  Diese 
  Biischel 
  

   sind 
  aber 
  doch 
  etwas 
  ganz 
  anderes 
  als 
  die 
  Schuppenbuschel 
  bei 
  An. 
  kochi 
  die 
  an 
  der 
  

   Bauchseite 
  in 
  der 
  Mittellinie 
  liegen." 
  

  

  Comparison 
  of 
  Malayan 
  specimens 
  of 
  kochi 
  with 
  Indian 
  specimens 
  of 
  halli 
  showed 
  

   that 
  they 
  were 
  the 
  same 
  species 
  and 
  the 
  latter 
  was 
  included 
  by 
  James 
  and 
  myself 
  

   in 
  our 
  list 
  of 
  Malayan 
  species 
  (Trans. 
  Far 
  East 
  Assn. 
  Trop. 
  Med. 
  2nd 
  Cong., 
  1912, 
  p. 
  

   317). 
  Examination 
  of 
  specimens 
  at 
  the 
  British 
  Museum 
  showed, 
  however, 
  that 
  halli, 
  

   James, 
  was 
  identical 
  with 
  kochi, 
  Donitz, 
  which 
  is 
  the 
  correct 
  name 
  for 
  this 
  Malayan 
  

   species. 
  In 
  James' 
  system 
  of 
  classification 
  it 
  is 
  named 
  Christophersia 
  kochi 
  (Christo- 
  

   phers, 
  Ann. 
  Trop. 
  Med. 
  Parasit, 
  vii, 
  p. 
  60, 
  1913). 
  

  

  The 
  mosquito 
  described 
  under 
  the 
  name 
  CeUiaflava 
  by 
  Miss 
  Ludlow 
  from 
  specimens 
  

   taken 
  in 
  the 
  Philippine 
  Islands 
  is 
  also 
  no 
  other 
  than 
  kochi, 
  Donitz, 
  as 
  has 
  recently 
  

   been 
  shown 
  by 
  Edwards 
  (Bull. 
  Ent. 
  Res., 
  iv, 
  p. 
  22, 
  1913). 
  

  

  The 
  description 
  and 
  illustration 
  of 
  " 
  Christophersia 
  halli 
  " 
  given 
  by 
  Strickland 
  in 
  

   his 
  " 
  Short 
  Key 
  to 
  the 
  Identification 
  of 
  the 
  Anopheline 
  Mosquitoes 
  of 
  Malaya 
  " 
  are 
  

   incorrect 
  for 
  this 
  species. 
  The 
  number 
  of 
  abdominal 
  scale-tufts 
  does 
  not 
  exceed 
  six 
  

   and 
  they 
  are 
  found 
  on 
  the 
  second 
  to 
  seventh 
  segments 
  only. 
  

  

  The 
  following 
  descriptions 
  are 
  based 
  on 
  the 
  study 
  of 
  the 
  ova 
  laid 
  by 
  a 
  female 
  in 
  

   captivity 
  and 
  of 
  the 
  larvae, 
  pupae 
  and 
  imagines 
  which 
  developed 
  therefrom. 
  Twenty 
  

   days 
  elapsed 
  from 
  the 
  deposition 
  of 
  the 
  ova 
  to 
  the 
  emerging 
  of 
  the 
  imagines.

  is

  end, 
  and 
  the 
  floats 
  do 
  not 
  

   touch 
  its 
  margin. 
  The 
  narrow 
  striated 
  frill
