  NOTES 
  AND 
  EXHIBITIONS. 
  

  

  Mr. 
  Swezey 
  exhibited 
  a 
  specimen 
  of 
  the 
  wasp, 
  Pison 
  iridipennis 
  

   Smith. 
  He 
  had 
  observed 
  this 
  species 
  very 
  abundant 
  at 
  the 
  Ex- 
  

   periment 
  Station 
  H. 
  S. 
  P. 
  A. 
  this 
  summer; 
  whereas, 
  he 
  had 
  not 
  

   previously 
  seen 
  it 
  on 
  the 
  island 
  of 
  Oahu. 
  He 
  had 
  taken 
  a 
  few 
  

   specimens 
  on 
  Maui, 
  in 
  1906.* 
  He 
  was 
  of 
  the 
  opinion 
  that 
  it 
  

   must 
  have 
  recently 
  rapidly 
  increased 
  in 
  abundance. 
  

  

  Mr. 
  Giffard 
  exhibited 
  several 
  boxes 
  of 
  Cicindelidae 
  and 
  Ceram- 
  

   bycidae, 
  part 
  of 
  a 
  large 
  collection 
  of 
  North 
  American 
  (principally 
  

   western) 
  beetles 
  he 
  had 
  purchased 
  on 
  the 
  mainland. 
  The 
  collec- 
  

   tion 
  contained 
  about 
  8000 
  specimens, 
  and 
  4000 
  species, 
  deter- 
  

   mined 
  by 
  various 
  specialists.

  A 
  gravid 
  female 
  caught 
  and 
  placed 
  in 
  a 
  breeding 
  jar, 
  October 
  

   15, 
  1906, 
  deposited 
  during 
  the 
  night 
  380 
  eggs 
  on 
  the 
  cloth 
  cover- 
  

   ing 
  the 
  breeding 
  jar. 
  The 
  fact 
  that 
  there 
  is 
  somewhat 
  of 
  varia- 
  

   tion 
  in 
  shade 
  of 
  color 
  in 
  this 
  species 
  of 
  moth, 
  suggested 
  the 
  idea 
  

   that 
  here 
  was 
  a 
  good 
  opportunity 
  to 
  try 
  some 
  breeding 
  experi- 
  

   ments 
  with 
  color 
  variation. 
  These 
  eggs 
  hatched 
  Oct. 
  20; 
  about 
  

   100 
  attained 
  full-growth 
  and 
  entered 
  soil 
  to 
  pupate 
  Nov. 
  10-15; 
  

   80 
  moths 
  (43 
  males 
  and 
  37 
  females) 
  emerged 
  Nov. 
  19 
  to 
  Dec. 
  5. 
  

  

  * 
  Later 
  in 
  September, 
  found 
  very 
  abundant 
  at 
  Koloa, 
  Kauai. 
  Hence, 
  

   is 
  apparently 
  well 
  distributed 
  in 
  the 
  group, 
  altho 
  I 
  have 
  found 
  no 
  records 
  

   of 
  it 
  on 
  Hawaii.
