  of 
  his 
  observation 
  chambers 
  

   the 
  pupa 
  of 
  dcypus 
  olens. 
  He 
  pointed 
  out 
  that 
  the 
  pupa 
  

   stood 
  upright 
  on 
  its 
  tail 
  on 
  the 
  cast 
  larval 
  skin, 
  and 
  that 
  strong 
  

   spines 
  on 
  the 
  body 
  kept 
  it 
  from 
  direct 
  contact 
  with 
  the 
  sides 
  of 
  the 
  

   pupal 
  chamber. 
  

  

  He

  Coleopteron 
  Tiniarcha 
  tenebricosa 
  

   in 
  its 
  pupation 
  chamber 
  in 
  one 
  of 
  his 
  observation 
  cages. 
  He 
  stated 
  

   that 
  the 
  eggs 
  were 
  laid 
  in 
  the 
  autumn 
  and 
  hatched 
  in 
  the 
  spring, 
  

   and 
  that 
  the 
  larvte 
  were 
  now 
  ready 
  for 
  pupation. 
  He

  of 
  the 
  first

  works 
  with

  in 
  this 
  country, 
  in 
  

   appearance 
  resembling 
  the 
  lily-of-the-valley, 
  but 
  nearly 
  allied 
  to 
  

   the 
  Solomon-seal. 
  

  

  Mr. 
  K. 
  Adkin 
  and 
  the 
  President 
  referred 
  to 
  the

  and 
  what 
  had 
  been 
  done 
  hitherto 
  to 
  

   preserve 
  this 
  open 
  space. 
  He 
  appealed 
  for 
  subscriptions 
  to 
  the 
  

   fund 
  in 
  order 
  that

  good 
  work 
  might 
  be 
  carried 
  on
