  This 
  pretty 
  species 
  varies 
  considerably 
  in 
  the 
  nature 
  of 
  its 
  

   markings, 
  being 
  sometimes 
  without 
  the 
  yellow 
  green 
  spots 
  near 
  

   the 
  shoulder, 
  and 
  sometimes 
  with 
  the 
  spots 
  produced 
  into 
  a 
  

   narrow 
  transverse 
  wavy 
  band.

  Sting 
  of 
  Bee. 
  — 
  Huber 
  says, 
  that 
  " 
  the 
  sting 
  by 
  which 
  this 
  little 
  

   animal 
  defends 
  itself 
  is 
  composed 
  of 
  three 
  parts, 
  the 
  sheath 
  and 
  

   two 
  darts. 
  The 
  sheath, 
  which 
  has 
  a 
  sharp 
  point, 
  makes 
  the 
  first 
  

   impression. 
  The 
  sheath 
  sometimes 
  sticks 
  so 
  fast 
  to 
  the 
  wound, 
  

   that 
  the 
  insect 
  is 
  obliged 
  to 
  leave 
  it 
  behind 
  ; 
  and 
  to 
  the 
  bee 
  itself 
  

   the 
  mutilation 
  proves 
  fatal." 
  The 
  sheath, 
  however, 
  makes 
  no 
  

   impression, 
  and 
  I 
  have 
  never 
  found 
  it 
  to 
  enter 
  or 
  make 
  a 
  wound 
  ; 
  

   it 
  is 
  large 
  near 
  the 
  base, 
  and 
  gradually 
  tapers 
  to 
  a 
  point, 
  and 
  is 
  

   quite 
  smooth, 
  and 
  if 
  it 
  did 
  make 
  an 
  incision 
  the 
  bee 
  would 
  be 
  

   able 
  to 
  draw 
  it 
  back 
  again 
  without 
  hurting 
  itself. 
  The 
  barbs 
  

   which 
  do 
  the 
  mischief 
  are 
  very 
  sharp 
  ; 
  and 
  when 
  they 
  penetrate, 
  

   they 
  hold 
  fast 
  to 
  the 
  wound 
  like 
  a 
  fish-hook, 
  and 
  the 
  bee 
  is 
  mostly 
  

   unable 
  to 
  draw 
  ihem 
  out 
  of 
  the 
  wound, 
  always 
  leaving 
  the 
  darts 
  

   with 
  the 
  sheath 
  ; 
  and 
  it 
  seems 
  impossible 
  to 
  leave 
  the 
  sheath 
  

   behind 
  without 
  the 
  darts, 
  as 
  they 
  are 
  all 
  rooted 
  firmly 
  together. 
  

   I 
  know 
  not 
  whether, 
  when 
  thus 
  mutilated, 
  they 
  die, 
  or 
  whether 
  

   they 
  are 
  killed 
  or 
  driven 
  away 
  by 
  the 
  other 
  bees. 
  

  

  Moss-carder 
  Humble 
  Bees. 
  — 
  Respecting 
  the 
  humble 
  bee, 
  

   Reaumur 
  says, 
  that 
  " 
  the 
  community, 
  which 
  numbers 
  from 
  20 
  

   to 
  300, 
  consists 
  of 
  females 
  of 
  two 
  sizes 
  — 
  the 
  very 
  largest 
  and 
  

   the 
  small 
  ones 
  ; 
  males, 
  which 
  are 
  stingless 
  ; 
  and 
  neuters.
