  I 
  have 
  experienced 
  considerable 
  difficulty 
  in 
  identifying 
  

   the 
  numerous 
  species 
  of 
  this 
  large 
  family, 
  described 
  by 
  the 
  

   late 
  Mr. 
  F. 
  Smith, 
  of 
  the 
  British 
  Museum. 
  This 
  is 
  more 
  

   particularly 
  the 
  case 
  with 
  the 
  black 
  species, 
  and 
  with 
  those 
  

   related 
  to 
  Salius 
  flavus, 
  Fab, 
  These 
  latter 
  I 
  find 
  to 
  be 
  

   especially 
  puzzling, 
  from 
  the 
  fact 
  that 
  the 
  same 
  type 
  of 
  

   colouration 
  is 
  found 
  in 
  two 
  of 
  the 
  sections 
  of 
  Salius 
  and 
  in 
  

   Pompilius. 
  I 
  have 
  myself, 
  with 
  the 
  aid 
  of 
  numerous 
  

   examples, 
  come 
  to 
  definite 
  conclusions 
  as 
  to 
  the 
  limits 
  of 
  

   the 
  species 
  with 
  those 
  of 
  the 
  y7crw/j-colouration 
  ; 
  but 
  I 
  am 
  

   in 
  so 
  much 
  difficulty 
  about 
  the 
  nomenclature, 
  that 
  I 
  have 
  

   decided 
  to 
  leave 
  them 
  over 
  until 
  I 
  have 
  had 
  an 
  opportunity 
  

   of 
  examining 
  Smith's 
  types. 
  I 
  am 
  the 
  more 
  inclined 
  to 
  do 
  

   so 
  from 
  finding 
  in 
  Mr. 
  Rothney's 
  collection 
  a 
  Ponipihis, 
  and 
  

   a 
  Salius 
  named 
  dorsalis, 
  Lep., 
  by 
  Mr. 
  Smith. 
  

  

  As 
  regards 
  the 
  genera, 
  I 
  have 
  adopted 
  them 
  as 
  defined 
  

   by 
  Kohl 
  in 
  his 
  paper 
  "

  Guttungen 
  der 
  Pompiliden

  The 
  species 
  of 
  FonipilidcE, 
  as 
  a 
  rule, 
  store 
  their 
  nests 
  with 
  

   spiders 
  ; 
  but 
  very 
  little 
  is 
  known 
  about 
  the 
  habits 
  of 
  the 
  

   Indian 
  species. 
  Major 
  Bingham 
  describes 
  the 
  nest 
  of 
  

   Fompilus 
  bracatus 
  as 
  a 
  " 
  burrow 
  in 
  the 
  ground 
  at 
  the 
  foot 
  

   of 
  a 
  large 
  fern," 
  and 
  he 
  observed 
  it 
  provisioning 
  its 
  nest
