  The

  regular 
  meeting 
  was 
  held 
  at

  Notes 
  and 
  Exhibitions. 
  

  

  Mr. 
  G. 
  W. 
  Kirkaldy 
  exhibited 
  specimens 
  of 
  a 
  large 
  black 
  

   Staphylinid 
  Beetle, 
  which 
  came 
  to 
  light 
  commonly. 
  Mr. 
  Schwarz 
  

   has 
  doubtfully 
  determined 
  it, 
  as 
  Philonthus 
  prolatus 
  Sharp, 
  a 
  

   Japanese 
  species. 
  Mr. 
  Kotinsky 
  observed 
  that 
  this 
  species 
  

   occurs 
  quite 
  often 
  in 
  manure.

  Among 
  a 
  large 
  colony 
  of 
  cells 
  of 
  the 
  bee, 
  2 
  specimens 
  of 
  the 
  

   beetle 
  were 
  detected. 
  When 
  one 
  of 
  these 
  cells 
  was 
  opened 
  a 
  

   larva 
  of 
  the 
  same 
  beetle 
  vv^as 
  found 
  within 
  and 
  no 
  trace 
  of 
  any 
  

   stage 
  of 
  the 
  bee. 
  Several 
  bee 
  cells 
  had 
  the 
  side 
  exit-holes 
  of 
  the 
  

   beetle. 
  The 
  cells 
  were 
  put 
  away 
  in 
  a 
  breeding 
  tube 
  and 
  several 
  

   more 
  beetles 
  issued 
  subsequently. 
  The 
  presumption 
  is 
  that 
  the 
  

   beetle 
  oviposits 
  upon 
  the 
  bee 
  cell, 
  and 
  the 
  grub 
  therefrom 
  bores 
  

   its 
  way 
  into 
  the 
  cell. 
  Whether 
  its 
  food 
  therein 
  is 
  the 
  pollen 
  

   bread 
  or 
  the 
  bee 
  larva 
  has 
  not 
  been 
  ascertained, 
  but 
  the 
  latter 
  

   invariably 
  dies 
  either 
  from 
  starvation 
  or 
  injuries 
  inflicted 
  by 
  the 
  

   beetle 
  larva. 
  This 
  Megachilid 
  being 
  seriously 
  destructive 
  to 
  

   many 
  shade 
  and 
  ornamental 
  plants 
  about 
  Honolulu, 
  it 
  was 
  grati- 
  

   fying 
  to 
  find 
  an 
  enemy 
  preying 
  upon 
  it. 
  A 
  remarkable 
  coincidence 
  

   is 
  that 
  the 
  same 
  species 
  of 
  beetle 
  was 
  collected 
  in 
  a 
  recent 
  large 
  

   shipment 
  of 
  rice 
  for 
  Honolulu. 
  

  

  Mr. 
  F. 
  W. 
  Terry 
  remarked 
  that 
  the 
  beetle-larva 
  might 
  have 
  

   been 
  feeding 
  on 
  the 
  pollen 
  in 
  the 
  bee-cells, 
  and 
  therefore 
  it 
  would 
  

   be 
  only 
  indirectlv 
  an 
  enem.v 
  of 
  the 
  bee.
