  Notes 
  and 
  Exhibitions. 
  

  

  Mr. 
  O. 
  H. 
  Swezey 
  exhibited 
  a 
  collection 
  of 
  eleven 
  species 
  of 
  

   Odynerus 
  collected 
  by 
  him 
  in 
  lao 
  Valley, 
  Maui, 
  July 
  29th, 
  1906, 
  

   consisting 
  of 
  0. 
  nigripennis 
  (numerous), 
  0. 
  insulicola 
  (7), 
  0. 
  

   molokaiensis 
  (4), 
  0. 
  ptirpurijer 
  (3), 
  O.instabilis 
  {3),0.konan'US 
  (3), 
  

   O. 
  ecostatus 
  (3), 
  0. 
  sandwichensis 
  (1), 
  O. 
  camelinus 
  (1), 
  0. 
  homoeo- 
  

   gaster 
  (1), 
  and 
  0. 
  naiadum 
  (1). 
  Both 
  he 
  and 
  Dr. 
  Perkins 
  com- 
  

   mented 
  on 
  the 
  good 
  luck 
  that 
  attended 
  him 
  on 
  that 
  day, 
  to 
  have 
  

   collected 
  eleven 
  out 
  of 
  the 
  sixteen 
  species 
  known 
  to 
  occur 
  in 
  that 
  

   valley. 
  Dr. 
  Perkins 
  further 
  stated 
  while 
  he 
  collected 
  0. 
  molo- 
  

   kaiensis 
  on 
  Molokai 
  in 
  1892, 
  he 
  found 
  none 
  of 
  it 
  on 
  Maui 
  in 
  1893 
  

   and 
  1894. 
  In 
  1902 
  however 
  this 
  species 
  was 
  found 
  very 
  abun- 
  

   dant 
  in 
  lao 
  Valley, 
  from 
  which 
  he 
  concludes 
  that 
  it 
  must 
  have 
  

   been 
  introduced 
  there 
  by 
  the 
  agency 
  of 
  man. 
  Some 
  of 
  the 
  

   species 
  collected 
  by 
  Mr. 
  Swezey 
  were 
  not 
  collected 
  by 
  himself 
  

   in 
  that 
  valley 
  and 
  some 
  of 
  them, 
  as 
  0. 
  instabilis, 
  were 
  very 
  rare 
  

   there. 
  He 
  further 
  remarked 
  that, 
  by 
  a 
  careful 
  study 
  of 
  the 
  

   habitus, 
  mode 
  of 
  flight 
  etc., 
  of 
  the 
  different 
  species, 
  when 
  in 
  the 
  

   field, 
  the 
  most 
  closely 
  allied 
  forms 
  could 
  be 
  discriminated, 
  even 
  

   where 
  they 
  are 
  not 
  easily 
  separated 
  in 
  the 
  stud3^ 
  Thus, 
  four 
  

   examples 
  of 
  Odynerus 
  recently 
  collected 
  on 
  the 
  wing 
  amongst 
  

   swarms 
  of 
  0. 
  pseudochromus 
  , 
  but 
  suspected 
  of 
  being 
  different, 
  

   were 
  found 
  to 
  include 
  one 
  peculiar 
  variety 
  of 
  that 
  species, 
  one 
  

   0. 
  pseudochromoides 
  , 
  and 
  the 
  two 
  much 
  rarer 
  species 
  0. 
  paludi- 
  

   cola 
  and 
  0. 
  leiodemas. 
  To 
  be 
  able 
  to 
  pick 
  out 
  the 
  choice 
  species 
  

   from 
  the 
  very 
  common 
  ones 
  which 
  they 
  resemble, 
  is 
  a 
  great 
  help 
  

   to 
  the 
  collector 
  in 
  these 
  Islands, 
  where 
  large 
  genera 
  of 
  closely 
  

   allied 
  species 
  are 
  frequent. 
  

  

  Mr. 
  J. 
  Kotinsky 
  exhibited 
  books 
  recently 
  purchased 
  by 
  the 
  

   Board 
  of 
  Agriculture 
  and 
  Forestry, 
  among 
  them 
  a 
  copy 
  of 
  Ruuss- 
  

   cher's 
  "Histoire 
  Naturelle 
  de 
  la 
  Cochenille, 
  Justifiee 
  par 
  les 
  

   Documens 
  Authentiques," 
  published 
  in 
  Amsterdam, 
  1729, 
  the 
  

   even 
  pages 
  being 
  in 
  Dutch 
  and 
  the 
  odd 
  in 
  French. 
  The 
  titles 
  

   quoted 
  above 
  indicate 
  the 
  method 
  of 
  investigation 
  pursued 
  by 
  

   the 
  author.
