  CAMERON, 
  Hymenoptera 
  Orientalia. 
  

  

  following 
  papers 
  are 
  now 
  in 
  the 
  collection 
  of 
  Mr. 
  G. 
  A. 
  J. 
  

   Rothney 
  They 
  form 
  a 
  notable 
  addition 
  to 
  our 
  knowledge 
  

   of 
  the 
  hymenopterous 
  fauna 
  of 
  the 
  mountains 
  ; 
  but 
  these 
  

   papers 
  can 
  only 
  be 
  looked 
  upon 
  as 
  a 
  beginning 
  towards 
  

   an 
  enumeration 
  of 
  the 
  species, 
  which 
  must 
  number 
  many 
  

   hundreds, 
  and 
  more 
  probably 
  thousands. 
  The 
  fact 
  that 
  

   in 
  the 
  comparatively 
  small 
  region 
  of 
  Sikkim 
  there 
  are 
  

   found 
  about 
  600 
  species 
  of 
  Butterflies, 
  and 
  probably 
  

   thousands 
  of 
  Moths, 
  is 
  in 
  itself 
  sufficient 
  evidence 
  of 
  the 
  

   rich 
  harvest 
  which 
  awaits 
  the 
  student 
  of 
  Hymenoptera, 
  

   when 
  collectors 
  begin 
  to 
  pay 
  attention 
  to 
  other 
  groups 
  

   than 
  the 
  Lepidoptera. 
  The 
  specimens 
  were 
  collected 
  

   by 
  the 
  native 
  Lepchas, 
  some 
  of 
  whom 
  make 
  excellent 
  

   collectors 
  ; 
  but, 
  as 
  might 
  be 
  expected, 
  they 
  only 
  collect 
  

   large 
  or 
  medium 
  sized 
  species. 
  

  

  An 
  excellent 
  description 
  of 
  the 
  Khasia 
  Mountains 
  is 
  

   to 
  be 
  found 
  in 
  that 
  admirable 
  book 
  of 
  travels, 
  Hooker's 
  

   Himalayan 
  Journal. 
  

  

  Judging 
  from 
  the 
  present 
  collection, 
  the 
  Hymenoptera 
  

   of 
  the 
  eastern 
  Himalayan 
  Mountains 
  appear 
  to 
  be 
  

   markedly 
  different 
  from 
  those 
  found 
  in 
  the 
  western 
  part 
  

   of 
  the 
  range 
  ; 
  but 
  our 
  knowledge 
  of 
  the 
  fauna 
  of 
  the 
  

   western 
  parts 
  of 
  the 
  group, 
  to 
  say 
  nothing 
  of 
  the 
  northern 
  

   plains 
  and 
  of 
  the 
  mountains 
  of 
  Central 
  India, 
  is 
  so 
  small 
  that 
  

   it 
  is 
  useless 
  at 
  present 
  to 
  discuss 
  the 
  geographical 
  distri- 
  

   bution 
  and 
  relationship 
  of 
  the 
  species. 
  Some 
  of 
  the 
  species 
  

   constitute 
  well-marked 
  new 
  generic 
  types. 
  In 
  establishing 
  

   these, 
  I 
  have 
  not 
  taken 
  Foerster's 
  generic 
  revision 
  of 
  the 
  

   Ichneumonidce 
  as 
  a 
  basis. 
  If 
  I 
  were 
  to 
  do 
  so, 
  I 
  should 
  be 
  

   compelled 
  to 
  form 
  a 
  very 
  much 
  larger 
  number 
  of 
  new 
  

   genera 
  ; 
  but 
  as 
  the 
  system 
  adopted 
  by 
  Foerster 
  appears 
  

   to 
  me 
  to 
  be 
  largely 
  artificial, 
  I 
  have 
  not 
  followed 
  it.
