  An 
  extract 
  of 
  a 
  letter 
  from 
  Mr. 
  Henry 
  Doubleday, 
  announced 
  that 
  

   if 
  this 
  Sciaphila, 
  upon 
  further 
  examination, 
  were 
  proved 
  to 
  be 
  a 
  distinct 
  species, 
  he 
  in- 
  

   tended 
  to 
  describe 
  it.

  The 
  Secretary 
  announced 
  that 
  the 
  Council 
  had 
  determined 
  to 
  distribute 
  the 
  

   Society's 
  duplicate 
  specimens 
  of 
  British 
  Lepidoptera 
  among 
  the 
  Members. 
  

  

  Mr. 
  Westwood 
  exhibited 
  a 
  piece 
  of 
  honey-comb 
  sent 
  to 
  him 
  by 
  a 
  correspondent, 
  

   in 
  which 
  the 
  queen 
  had 
  laid 
  drone-eggs 
  in 
  worker-cells, 
  which 
  had 
  been 
  enlarged 
  for 
  

   this 
  |)urpose. 
  

  

  Mr. 
  Curtis 
  exhibited 
  some 
  Hymenoptera 
  and 
  Diptera 
  he 
  had 
  received 
  from 
  M. 
  

   Leon 
  Dufour 
  and 
  Signor 
  Passerini, 
  most 
  of 
  them 
  valuable 
  as 
  typical 
  specimens 
  of 
  spe- 
  

   cies 
  described 
  in 
  the 
  ' 
  Annales 
  de 
  la 
  Societe 
  Entomologique 
  de 
  France.' 
  In 
  the 
  box 
  

   also 
  was 
  Tryphon 
  nigriceps, 
  Grav., 
  a 
  species 
  new 
  to 
  this 
  country. 
  It 
  was 
  1)red 
  by 
  Mr. 
  

   Foxcroft 
  from 
  cocoons 
  of 
  Trichiosoma 
  lucorum, 
  which 
  he 
  found 
  in 
  Wales. 
  Mr. 
  

   Curtis 
  remarked 
  that 
  in 
  1828 
  he 
  had 
  bred 
  Tryphon 
  rufus 
  from 
  the 
  cocoon 
  of 
  his 
  Tri- 
  

   chiosoma 
  pratense, 
  the 
  larvcE 
  of 
  which 
  he 
  found 
  in 
  a 
  damp 
  meadow 
  near 
  Ambleside, 
  

   in 
  the 
  previous 
  year, 
  on 
  a 
  plant 
  he 
  did 
  not 
  remember, 
  it 
  certainly 
  was 
  not 
  whitethorn, 
  

   but 
  he 
  thought 
  a 
  Spirsea 
  or 
  some 
  herbaceous 
  plant. 
  The 
  Tryphon 
  nifulus 
  of 
  Stephens 
  

   is 
  the 
  male 
  of 
  T. 
  rufus. 
  These 
  species, 
  from 
  the 
  form 
  of 
  the 
  petiole, 
  belong 
  decidedly 
  

   to 
  the 
  genus 
  Mesoleptus, 
  which 
  Gravenhorst 
  hints 
  at 
  in 
  his 
  work; 
  but 
  the 
  multitude 
  

   of 
  exceptions 
  to 
  the 
  characters 
  of 
  the 
  genera 
  proposed 
  in 
  the 
  systematic 
  tables, 
  show 
  

   how 
  imperfect 
  the 
  latter 
  are, 
  and 
  how 
  difficult 
  it 
  is 
  to 
  study 
  the 
  IchneumonidiB. 
  

  

  Mr. 
  Stevens 
  exhibited 
  two 
  specimens 
  of 
  the 
  very 
  rare 
  British 
  longicorn 
  beetle, 
  

   Pogonocherus 
  fasciculatus, 
  taken 
  by 
  Mr. 
  Foxcroft, 
  in 
  the 
  Black 
  Forest, 
  Perthshire, 
  

   and 
  the 
  new 
  Noctiluca 
  from 
  Scotland, 
  but 
  being 
  a 
  female, 
  he 
  had 
  not 
  been 
  able 
  to 
  

   determine 
  the 
  species 
  with 
  certainty. 
  

  

  Mr. 
  Douglas 
  exhibited 
  specimens 
  of 
  the 
  scarce 
  moth, 
  Hyponomeuta 
  irrorellus, 
  

   reared 
  by 
  Mr. 
  W. 
  Kirby, 
  of 
  Wandsworth, 
  from 
  larvae 
  found 
  feeding 
  upon 
  Euonymus 
  

   EuropBBUs 
  ; 
  and 
  Mr. 
  Stainton 
  exhibited 
  some 
  of 
  the 
  cocoons. 
  

  

  Mr. 
  Wallace 
  exhibited 
  a 
  fine 
  new 
  longicorn 
  beetle, 
  Acanthocinus 
  sp. 
  ? 
  from 
  Cali- 
  

   fornia, 
  and 
  a 
  splendid 
  butterfly, 
  Zeonia 
  Octavius, 
  Fab., 
  from 
  Para. 
  

  

  Captain 
  C. 
  J. 
  Cox 
  laid 
  upon 
  the 
  table 
  a 
  block 
  of 
  wood 
  perforated 
  by 
  larvae 
  

   of 
  Cossus 
  ligniperda, 
  and 
  pieces 
  of 
  the 
  wood 
  and 
  bark 
  of 
  elm 
  and 
  ash, 
  illustrating 
  the 
  

   different 
  ways 
  of 
  mining 
  pursued 
  by 
  the 
  larvae 
  of 
  Scolytus 
  destructor 
  and 
  Hylesinus 
  

   Fraxini. 
  For 
  several 
  years 
  he 
  had 
  devoted 
  his 
  attention 
  to 
  these 
  insects, 
  especially 
  

   the 
  Scolyti, 
  and 
  he 
  was 
  convinced 
  that 
  their 
  ravages 
  were 
  so 
  extensive 
  as 
  to 
  be 
  of 
  great 
  

   importance. 
  Some 
  of 
  the 
  oldest 
  and 
  finest 
  elms 
  in 
  the 
  parks 
  had 
  been 
  destroyed, 
  and 
  

   young 
  sound 
  trees 
  were 
  not 
  exempt 
  from 
  their 
  attacks. 
  In 
  opposition 
  to 
  several 
  dis- 
  

   tinguished 
  entomologists, 
  be 
  was 
  convinced 
  that 
  Scolytus 
  destructor 
  attacked 
  sound 
  

   trees 
  and 
  caused 
  them 
  to 
  become 
  diseased, 
  patrly 
  through 
  the 
  influence 
  of 
  a 
  poison
