﻿PROCEEDINGS 
  OF 
  THE 
  FOURTH 
  ENTOMOLOGICAL 
  MEETING 
  209 
  

  

  I 
  propose 
  in 
  view 
  of 
  these 
  facts 
  to 
  speak, 
  with 
  reference 
  to 
  anopheline 
  

   distribution, 
  of 
  two 
  areas 
  in 
  India 
  (1) 
  Hindustan 
  and 
  (2) 
  Malayo-India. 
  

   The 
  general 
  lie 
  of 
  these 
  areas 
  is 
  shewn 
  in 
  Map 
  2 
  (Plate 
  XXXVII). 
  

  

  A 
  few 
  words 
  may 
  be 
  said 
  finally 
  as 
  to 
  the 
  Himalayan 
  species. 
  Of 
  

   these 
  A. 
  gigas 
  is 
  Malayan 
  and 
  has 
  been 
  found 
  in 
  Java 
  and 
  probably 
  in 
  

   the 
  Philippines. 
  The 
  common 
  and 
  ubiquitous 
  Himalayan 
  form 
  is 
  

   A. 
  lindesmji 
  which 
  appears 
  not 
  to 
  be 
  known 
  out 
  of 
  India. 
  Two 
  other 
  

   Anophelines 
  are 
  also 
  found 
  in 
  the 
  Himalayan 
  area 
  which 
  are 
  not 
  found 
  

   elsewhere 
  in 
  India, 
  viz., 
  the 
  two 
  tree-breeding 
  species, 
  A. 
  harianensis 
  

   (Holarctic) 
  and 
  A. 
  annandalei 
  (Malayan). 
  The 
  Himalayan 
  fauna 
  is 
  

   not 
  confined 
  to 
  the 
  Himalayas 
  but 
  occurs 
  also 
  at 
  high 
  levels 
  in 
  the 
  

   Assam 
  and 
  Peninsular 
  areas. 
  Thus 
  both 
  A. 
  gigas 
  and 
  A. 
  lindesayi 
  

   occur 
  in 
  the 
  Nilgiris 
  and 
  Palnis 
  in 
  South 
  India 
  though 
  these 
  are 
  separated 
  

   from 
  the 
  Himalayas 
  by 
  a 
  wide 
  extent 
  of 
  country 
  quite 
  unsuitable 
  to 
  

   these 
  species 
  which 
  are 
  restricted 
  to 
  high 
  altitudes, 
  A. 
  gigas 
  being 
  scarcely 
  

   ever 
  found 
  much 
  under 
  5,000 
  or 
  6,000 
  feet. 
  The 
  occurrence 
  of 
  these 
  

   Himalayan 
  species 
  in 
  the 
  isolated 
  plateaus 
  of 
  Southern 
  India 
  is 
  an 
  

   instance 
  of 
  what 
  is 
  found 
  also 
  I 
  believe 
  in 
  the 
  case 
  of 
  distributional 
  

   areas 
  of 
  some 
  mammals, 
  namely 
  those 
  of 
  Alpine 
  forms 
  which 
  exist 
  now 
  

   as 
  outliers 
  far 
  to 
  the 
  south 
  of 
  India 
  and 
  have 
  been 
  considered 
  as 
  indica- 
  

   ting 
  the 
  prevalence 
  at 
  one 
  time 
  of 
  temperate 
  conditions 
  where 
  now 
  is 
  

   a 
  tropical 
  climate. 
  

  

  There 
  remains 
  to 
  say 
  something 
  as 
  to 
  the 
  distribution 
  of 
  Indian 
  Culi- 
  

  

  cidse 
  other 
  than 
  Anophelines. 
  In 
  the 
  space 
  at 
  my 
  disposal 
  I 
  must 
  be 
  

  

  brief 
  and 
  so 
  cannot 
  enter 
  as 
  fully 
  as 
  I 
  should 
  like 
  into 
  this 
  matter. 
  In 
  a 
  

  

  Table 
  is 
  given 
  an 
  abstract 
  of 
  species 
  occurring 
  in 
  Africa, 
  Hindostan, 
  

  

  Malayo-India 
  and 
  Malay 
  with 
  the 
  number 
  of 
  species 
  common 
  to 
  these 
  

  

  areas. 
  It 
  will 
  be 
  seen 
  that 
  of 
  142 
  African 
  and 
  European 
  species 
  12 
  only 
  

  

  occur 
  in 
  India 
  and 
  of 
  these 
  12 
  some 
  are 
  very 
  widely-distributed 
  species, 
  

  

  e.g., 
  S. 
  fasciata, 
  C. 
  fafigans. 
  But 
  of 
  IGl 
  Malayan 
  species 
  56 
  occur 
  in 
  

  

  Malayo-India 
  and 
  at 
  least 
  ten 
  in 
  Hindostan. 
  Of 
  the 
  95 
  species 
  recorded 
  

  

  from 
  Malayo-India 
  40 
  only 
  are 
  at 
  present 
  not 
  recorded 
  from 
  Malay. 
  At 
  

  

  least 
  twenty-two 
  of 
  these 
  species 
  are 
  found 
  also 
  in 
  Hindostan, 
  forming 
  

  

  the 
  bulk 
  of 
  the 
  relatively 
  poor 
  culicine 
  fauna 
  (30 
  species) 
  of 
  this 
  area. 
  

  

  These 
  figures 
  must 
  not 
  be 
  considered 
  by 
  any 
  means 
  exact 
  especially 
  as 
  

  

  regards 
  the 
  Hindostan 
  area 
  in 
  which 
  it 
  is 
  probable 
  more 
  species 
  (mostly 
  

  

  those 
  of 
  Malayo-India) 
  will 
  eventually 
  be 
  recorded. 
  The 
  figures 
  show, 
  

  

  however, 
  numerically 
  "what 
  is 
  a 
  self-evident 
  fact 
  to 
  anyone 
  accustomed 
  

  

  to 
  collect 
  mosquitos. 
  The 
  rich 
  fauna 
  of 
  moist 
  tropical 
  Malay 
  is 
  still 
  

  

  found 
  in 
  forests 
  and 
  moist 
  jungles 
  almost 
  wherever 
  they 
  occur 
  in 
  India. 
  

  

  In 
  the 
  relatively 
  drier 
  parts 
  of 
  India 
  this 
  heavy 
  jungle 
  fauna 
  largely 
  

  

  disappears, 
  leaving 
  chiefly 
  the 
  swamp 
  breeders, 
  agrarian 
  and 
  domestic
