  The 
  President 
  announced 
  that 
  the 
  Society 
  offered 
  a 
  prize 
  of 
  £b 
  5s. 
  for 
  the

  the 
  Natural 
  History 
  of 
  the 
  species 
  of 
  Coccus 
  injurious 
  to 
  fruit-trees 
  in 
  this 
  

   country 
  (with 
  an 
  especial 
  reference 
  to 
  the 
  " 
  mussel-scale 
  " 
  of 
  the 
  apple, 
  of 
  which 
  a 
  full, 
  

   and 
  particular 
  account 
  is 
  to 
  be 
  given), 
  and 
  the 
  best 
  means 
  of 
  preventing 
  their 
  ravages. 
  

  

  The 
  essays, 
  each 
  distinguished 
  by 
  a 
  motto, 
  and 
  with 
  the 
  author's 
  name 
  in 
  a 
  dis- 
  

   tinct 
  sealed 
  envelope, 
  to 
  be 
  addressed 
  " 
  To 
  the 
  President 
  and 
  Council 
  of 
  the 
  Entomo- 
  

   logical 
  Society," 
  and 
  delivered 
  on 
  or 
  beibre 
  the 
  31st 
  of 
  December 
  next. 
  

  

  Mr. 
  Spence 
  exhibited 
  specimens 
  of 
  a 
  Thrips, 
  received 
  through 
  Dr. 
  Lankester 
  from 
  

   Dr. 
  Theophilus 
  Thompson, 
  to 
  whom 
  they 
  had 
  been 
  sent 
  from 
  Australia, 
  where 
  they 
  

   prevented 
  rose-trees 
  from 
  blossoming 
  by 
  eating 
  the 
  petals 
  of 
  the 
  flowers. 
  

  

  Mr. 
  S. 
  Stevens 
  exhibited 
  a 
  specimen 
  of 
  each 
  of 
  the 
  rare 
  Coleoptera, 
  Agasma 
  senii- 
  

   crudum 
  and 
  Calodera 
  Kirbii, 
  lately 
  received 
  from 
  Australia. 
  

  

  Mr. 
  T. 
  Spencer 
  exhibited 
  a 
  specimen 
  of 
  Choerocampa 
  Celerio, 
  captured 
  last 
  Octo- 
  

   ber 
  in 
  the 
  Regent's 
  Park, 
  and 
  a 
  scorpion, 
  found 
  last 
  summer 
  in 
  the 
  middle 
  of 
  a 
  field 
  

   at 
  Edgeware. 
  

  

  Mr. 
  Douglas, 
  on 
  the 
  part 
  of 
  Mr. 
  A. 
  R. 
  Hogan, 
  exhibited 
  the 
  specimen 
  of 
  Hippar- 
  

   chia 
  Janira, 
  with 
  six 
  whitish 
  appendages 
  to 
  the 
  haustellum, 
  respecting 
  which 
  he 
  had 
  

   sent 
  an 
  inquiry 
  to 
  the 
  'Zoologist' 
  (p. 
  3775), 
  and 
  which 
  Mr. 
  Douglas 
  had 
  answered 
  in 
  

   the 
  same 
  journal 
  (p. 
  3809), 
  considering 
  the 
  presence 
  of 
  these 
  bodies 
  to 
  be 
  attributable 
  

   to 
  the 
  adhesion 
  of 
  parts 
  of 
  flowers. 
  Subsequent 
  examination 
  of 
  the 
  butterfly, 
  kindly 
  

   sent 
  by 
  Mr. 
  Hogan, 
  had 
  confirmed 
  this 
  impression. 
  

  

  The 
  President 
  said 
  he 
  was 
  convinced 
  that 
  Mr. 
  Douglas 
  was 
  correct 
  in 
  his 
  opinion, 
  

   for 
  not 
  only 
  did 
  he 
  find 
  the 
  appendages 
  in 
  question 
  to 
  be 
  the 
  pollen-masses 
  of 
  an 
  Or- 
  

   chidaceous 
  plant, 
  but 
  he 
  identified 
  the 
  very 
  species 
  as 
  Orchis 
  bifolia. 
  The 
  pollen-gra- 
  

   nules 
  were 
  still 
  distinctly 
  observable 
  at 
  the 
  distal 
  extremity 
  of 
  the 
  appendages, 
  while 
  

   the 
  basal 
  end, 
  always 
  extremely 
  viscid, 
  had 
  fixed 
  itself 
  firmly 
  to 
  the 
  inaxillsB 
  of 
  the 
  

   insect. 
  These 
  extraneous 
  bodies 
  are 
  aflixed 
  to 
  the 
  maxillae 
  in 
  very 
  regular 
  order, 
  but 
  

   he 
  regarded 
  their 
  position 
  as 
  purely 
  accidental 
  ; 
  and 
  the 
  hairs 
  observed 
  by 
  Mr. 
  Ho- 
  

   gan 
  adhering 
  to 
  the 
  pollen-masses 
  were 
  no 
  part 
  of 
  the 
  plant, 
  but 
  doubtless 
  derived 
  

   from 
  the 
  palpi 
  or 
  pectus 
  of 
  the 
  butterfly. 
  The 
  occurrence 
  of 
  pollen-masses 
  on 
  various 
  

   parts 
  of 
  insects 
  had 
  been 
  repeatedly 
  noticed 
  by 
  botanists 
  as 
  well 
  as 
  entomologists; 
  they 
  

   are 
  very 
  common 
  on 
  the 
  heads 
  of 
  wild 
  bees, 
  especially 
  in 
  foreign 
  countries, 
  in 
  such 
  

   cases 
  being 
  not 
  only 
  derived 
  from 
  Orchids, 
  but 
  also 
  from 
  Asclepiads, 
  — 
  a 
  natural 
  order 
  

   of 
  plants 
  which 
  does 
  not 
  occur 
  wild 
  in 
  this 
  country, 
  and 
  which, 
  although 
  widely 
  differ- 
  

   ing 
  from 
  the 
  Orchids 
  in 
  other 
  structural 
  peculiarities, 
  possesses 
  similarly 
  constructed 
  

   pollen-masses. 
  To 
  such 
  an 
  extent 
  has 
  this 
  phenomenon 
  prevailed 
  in 
  some 
  instances, 
  

   that 
  botanists 
  have 
  conjectured 
  that 
  Nature 
  availed 
  herself 
  of 
  the 
  services 
  of 
  the 
  bees 
  

   to 
  carry 
  out 
  the 
  fecundating 
  process, 
  for 
  many 
  Orchids, 
  without 
  their 
  assistance 
  in 
  con- 
  

   veying 
  the 
  pollen-granules 
  from 
  one 
  flower 
  to 
  another, 
  failed 
  to 
  mature 
  their 
  seeds. 
  

   The 
  pollen-masses 
  are 
  very 
  carefully 
  and 
  accurately 
  described 
  by 
  the 
  late 
  Sir 
  J. 
  E. 
  

   Smith, 
  Dr. 
  Lindley, 
  and 
  other 
  botanists. 
  

  

  The 
  Secretary 
  read 
  the 
  following 
  notes, 
  communicated 
  by 
  Professor 
  Zeller, 
  Hono- 
  

   rary 
  Member 
  of 
  the 
  Society. 
  

  

  " 
  Impaled 
  Insects. 
  — 
  I 
  only 
  remember 
  two 
  examples 
  of 
  impaled 
  insects, 
  but 
  both 
  of 
  

   them 
  afford 
  good 
  evidence 
  of 
  the 
  cause 
  of 
  their 
  position. 
  In 
  one 
  of 
  these 
  cases 
  the
