  PROCEEDINGS 
  OF 
  THE 
  FOURTH 
  ENTOMOLOGICAL 
  MEETING 
  

  

  feature 
  of 
  this 
  fauna 
  is 
  that 
  it 
  is 
  not 
  restricted 
  to 
  the 
  Himalayas 
  but 
  

   occurs 
  as 
  outliers 
  far 
  to 
  the 
  south 
  in 
  Tropical 
  India, 
  a 
  point 
  I 
  shall 
  

   return 
  to 
  later. 
  

  

  Broadly 
  speaking, 
  after 
  excluding 
  the 
  fringes 
  of 
  what 
  are 
  clearly 
  

   western 
  faunas 
  and 
  practically 
  influence 
  only 
  the 
  Trans-Indus 
  area 
  

   we 
  can 
  distinguish 
  in 
  the 
  Indian 
  Empire 
  two 
  types 
  of 
  Anopheline 
  fauna. 
  

  

  To 
  the 
  first 
  we 
  can 
  assign 
  the 
  Indo-gangetic 
  tract, 
  the 
  Deccan 
  and 
  

   to 
  some 
  extent 
  the 
  Peninsular 
  area 
  generally. 
  

  

  To 
  the 
  second 
  we 
  must 
  assign 
  the 
  countries 
  east 
  of 
  Calcutta 
  and 
  

   the 
  Malabar 
  tract 
  with 
  Ceylon 
  and 
  possibly 
  to 
  some 
  extent 
  the 
  coastal 
  

   and 
  hill 
  areas 
  of 
  the 
  Madras 
  tract. 
  

  

  Examining 
  the 
  essential 
  nature 
  of 
  the 
  difference 
  in 
  these 
  types 
  of 
  

   fauna 
  one 
  is 
  struck 
  by 
  the 
  fact 
  that 
  it 
  is 
  chiefly 
  in 
  the 
  degree 
  of 
  

   absence 
  of 
  Malayan 
  forms 
  that 
  these 
  differ. 
  It 
  would 
  appear 
  legitimate 
  

   to 
  say 
  that 
  the 
  Indian 
  area 
  is 
  characterized 
  by 
  an 
  impoverished 
  

   Malayan 
  Anopheline 
  fauna, 
  this 
  impoverishment 
  reaching 
  to 
  a 
  high 
  

   degree 
  in 
  the 
  first 
  series 
  of 
  tracts 
  and 
  being 
  but 
  little 
  marked 
  in 
  the 
  

   second. 
  There 
  is 
  on 
  the 
  whole 
  a 
  far 
  greater 
  change 
  beyond 
  the 
  western 
  

   frontier 
  than 
  to 
  the 
  east. 
  This 
  will 
  be 
  seen 
  from 
  the 
  following 
  abstract

  As 
  Major 
  Gill, 
  I. 
  M.S., 
  once 
  aptly 
  put 
  it 
  to 
  me, 
  there 
  is 
  something 
  

   like 
  a 
  mosquito 
  fault 
  at 
  about 
  the 
  Indus. 
  

  

  Though 
  few 
  in 
  number 
  there 
  appear 
  to 
  be 
  quite 
  definitely 
  some 
  Indian 
  

   species 
  whose 
  zoocentre 
  is 
  included 
  in 
  the 
  Indian 
  Empire 
  and 
  which 
  

   help 
  to 
  make 
  good 
  the 
  impoverishment 
  of 
  Malayan 
  forms 
  in 
  a 
  large 
  

   part 
  of 
  the 
  area. 
  These 
  species 
  often 
  have 
  a 
  westerly 
  focus 
  or 
  tendency 
  

   of 
  occurrence. 
  One 
  may 
  mention 
  A. 
  stephensii 
  unrecorded 
  in 
  Malay 
  

   and 
  stretching 
  to 
  the 
  confines 
  of 
  the 
  Arabian 
  Desert 
  ; 
  A. 
  culicifacies, 
  

   a 
  dominant 
  Indian 
  form 
  not 
  recorded 
  from 
  Malay 
  but 
  occurring 
  as 
  far 
  

   at 
  least 
  westward 
  as 
  Arabia 
  and 
  Palestine. 
  More 
  strictly 
  Indian 
  still 
  

   appear 
  to 
  be 
  the 
  species 
  A. 
  theohaldi, 
  A. 
  willmori 
  and 
  A. 
  fowleri. 
  Also 
  

   the 
  species 
  A. 
  listoni 
  may 
  not 
  be 
  quite 
  identical 
  with 
  the 
  African 
  A. 
  

   funestus. 
  A. 
  jeyporiensis 
  is 
  also 
  a 
  species 
  not 
  recorded 
  from 
  Malay 
  

   though 
  one 
  would 
  have 
  expected 
  its 
  occurrence 
  in 
  this 
  region.
