  Last 
  autumn 
  Messrs. 
  Grant 
  and 
  Dunning 
  found 
  several 
  of 
  the 
  

   cases 
  at 
  Putney 
  on 
  Slellaria 
  holostea, 
  and 
  the 
  larva 
  lived 
  through 
  

   the 
  winter. 
  In 
  April 
  this 
  year, 
  Mr. 
  Stainton 
  discovered 
  the 
  

   larvae 
  on 
  the 
  same 
  plant 
  growing 
  in 
  hedges 
  at 
  Lewisham. 
  The 
  

   specific 
  name 
  has 
  proved 
  to 
  be 
  singularly 
  inappropriate, 
  for 
  the 
  

   larvae 
  are 
  quite 
  gregarious, 
  five 
  or 
  six 
  being 
  commonly 
  seen 
  on 
  a 
  

   shoot 
  of 
  the 
  plant 
  Slellaria 
  : 
  but 
  they 
  are 
  difficult 
  to 
  rear.

  Zeller 
  described 
  this 
  species 
  

   from 
  a 
  single 
  specimen 
  bred 
  from 
  a 
  case 
  found 
  by 
  him 
  attached 
  

   to 
  grass 
  ; 
  it 
  is 
  very 
  rare 
  in 
  collections 
  in 
  this 
  country.

  Notes 
  on 
  the 
  Development 
  of 
  Osmia 
  parietina, 
  and 
  

   other 
  British 
  Insects. 
  By 
  F. 
  Smith, 
  Esq. 
  

   [Read 
  August 
  2nd, 
  1852.] 
  

   In 
  the 
  ninth 
  volume 
  of 
  the 
  "Zoologist" 
  I 
  published 
  some 
  account 
  

   of 
  the 
  habits 
  of 
  Osmia 
  parietina, 
  a 
  little 
  bee 
  which 
  had 
  selected 
  

   the 
  under 
  side 
  of 
  a 
  stone 
  on 
  which 
  to 
  affix 
  the 
  balls 
  of 
  pollen 
  on 
  

   wliich 
  to 
  deposit 
  its 
  eggs. 
  This 
  stone 
  was 
  discovered 
  in 
  early 
  

   spring 
  on 
  the 
  Grampian 
  Hills, 
  near 
  Perth, 
  too 
  early 
  in 
  the 
  

   season 
  for 
  any 
  of 
  the 
  brood 
  to 
  have 
  issued 
  from 
  the 
  cocoons. 
  At 
  

   the 
  time 
  of 
  its 
  discovery 
  about 
  one-third 
  of 
  the 
  cocoons 
  were 
  

   empty, 
  showing 
  that 
  at 
  least 
  that 
  portion 
  of 
  the 
  mass 
  had 
  been 
  

   developed 
  during 
  the 
  previous 
  season. 
  The 
  only 
  difficulty 
  was 
  

   this 
  — 
  had 
  the 
  parent 
  bee 
  or 
  bees 
  deposited 
  on 
  the 
  same 
  stone 
  two 
  

   successive 
  seasons 
  ? 
  The 
  stone 
  came 
  into 
  my 
  possession 
  in 
  the 
  

   autumn 
  of 
  1851 
  ; 
  and 
  in 
  the 
  month 
  of 
  November, 
  finding 
  that 
  a 
  

   number 
  of 
  the 
  cocoons 
  were 
  still 
  unopened, 
  I 
  cut 
  one 
  or 
  two 
  in 
  

   such 
  a 
  manner 
  that 
  I 
  could 
  raise 
  as 
  it 
  were 
  a 
  trap-door 
  and 
  watch 
  

   the 
  progress 
  of 
  the 
  bees. 
  All 
  that 
  I 
  opened 
  contained 
  larvae. 
  

   After 
  closing 
  them, 
  and 
  carefully 
  preventing 
  the 
  admission 
  of 
  air,
