  insect 
  in 
  all 
  its 
  stages; 
  but 
  as 
  its 
  growth 
  to 
  maturity 
  is 
  extremely 
  rapid, 
  and 
  as 
  its 
  life 
  

   in 
  the 
  imago 
  state 
  is 
  usually 
  prolonged, 
  it 
  follows 
  that 
  the 
  injury 
  caused 
  by 
  the 
  insect 
  in 
  

   its 
  perfect, 
  is 
  much 
  greater 
  than 
  that 
  in 
  its 
  preparatory 
  st;t»es. 
  It 
  is 
  worthy 
  of 
  remark, 
  

   that 
  all 
  the 
  species 
  of 
  ferns 
  are 
  not 
  equally 
  obnoxious 
  tc 
  its 
  attacks 
  ; 
  for 
  of 
  our 
  Eng- 
  

   lish 
  ferns, 
  Osmunda 
  regalis 
  and 
  Asplenium 
  lanceolatum 
  are 
  rarely 
  touched; 
  Laslrea 
  

   Filix-mas, 
  L. 
  spiuosa, 
  L. 
  uligiiiosa, 
  L. 
  multitlora 
  and 
  L. 
  rigida 
  are 
  greatly 
  injured 
  ; 
  

   and 
  Asplenium 
  Adiautum-nigrum 
  and 
  Polypodium 
  vulgare 
  are 
  sometimes 
  absolutely 
  

   killed. 
  When 
  disturbed, 
  the 
  insect 
  leaps 
  off 
  the 
  frond 
  after 
  the 
  usual 
  manner 
  of 
  the 
  

   Cercopidae 
  ; 
  but 
  when 
  once 
  committed 
  to 
  the 
  air, 
  it 
  flies 
  about, 
  and 
  even 
  hovers, 
  with 
  

   all 
  the 
  facility 
  of 
  a 
  Musca. 
  The 
  smoke 
  of 
  tobacco, 
  if 
  the 
  greenhouse 
  can 
  be 
  sufficiently 
  

   closed, 
  is 
  fatal 
  ; 
  but 
  there 
  is 
  a 
  great 
  deal 
  of 
  difficulty 
  in 
  applying 
  it 
  effectually 
  iu 
  a 
  

   large 
  or 
  imperfectly 
  closed 
  house. 
  The 
  nuisance 
  may 
  also 
  be 
  in 
  some 
  degree 
  abated, 
  

   by 
  burning 
  the 
  fronds 
  in 
  autumn, 
  and 
  thus, 
  iu 
  all 
  probability, 
  destroying 
  the 
  eggs."

  Description 
  of 
  a 
  new 
  Species 
  of 
  Lithocolletis, 
  — 
  L. 
  irradiella." 
  By 
  John 
  

   Scott, 
  Esq. 
  It 
  is 
  very 
  like 
  L. 
  lautella, 
  but 
  the 
  anterior 
  wings 
  are 
  darker, 
  the 
  streaks 
  

   more 
  slender, 
  and 
  the 
  spot 
  at 
  the 
  anal 
  angle 
  not 
  on 
  the 
  inner 
  margin. 
  The 
  specimen 
  

   from 
  which 
  the 
  description 
  was 
  made, 
  was 
  taken 
  in 
  July, 
  in 
  a 
  damp 
  wood 
  near 
  Ren- 
  

   frew, 
  and 
  was 
  exhibited 
  to 
  the 
  meeting. 
  

  

  Read 
  the 
  following 
  extracts 
  from 
  a 
  letter 
  to 
  the 
  Secretary, 
  by 
  the 
  Rev. 
  Joseph 
  

   Greene, 
  of 
  Wendover 
  : 
  — 
  

  

  " 
  No 
  genus 
  of 
  moths 
  that 
  I 
  am 
  acquainted 
  with 
  is 
  so 
  subject 
  to 
  Ichneumons 
  as 
  

   Notodonta. 
  Of 
  N. 
  camelina, 
  I 
  should 
  say 
  seven 
  in 
  every 
  ten 
  are 
  pierced. 
  I 
  found 
  

   five 
  of 
  N. 
  trepida 
  this 
  year, 
  four 
  were 
  pierced 
  ; 
  and 
  the 
  same 
  with 
  N. 
  ziczac, 
  which 
  

   is 
  common 
  here 
  in 
  the 
  larva 
  state. 
  N. 
  dictaea 
  and 
  dicteeoides 
  are 
  apparently 
  more 
  

   fortunate." 
  

  

  " 
  The 
  singular 
  epidemic 
  of 
  muscardine 
  ? 
  exists 
  to 
  a 
  great 
  extent 
  among 
  larvae 
  this 
  

   year, 
  arising, 
  I 
  imagine, 
  from 
  the 
  extreme 
  dampness 
  of 
  the 
  season. 
  The 
  characteris- 
  

   tics 
  of 
  the 
  disease 
  are, 
  that 
  when 
  the 
  larva 
  is 
  fully 
  grown, 
  it 
  suddenly, 
  and 
  without 
  the 
  

   slightest 
  apparent 
  premonitory 
  symptom, 
  becomes 
  stiff 
  ?.nd 
  rigid, 
  with 
  the 
  fore 
  part 
  of 
  

   the 
  body 
  extended, 
  and 
  iu 
  a 
  short 
  time 
  dries 
  up. 
  I 
  have 
  found 
  it 
  in 
  zic-zac, 
  Coryli, 
  

   antiqua, 
  angularia, 
  &c. 
  My 
  house 
  being 
  unfortunately 
  very 
  damp, 
  I 
  should 
  not 
  have 
  

   thought 
  much 
  of 
  this 
  circumstance, 
  but 
  it 
  has, 
  I 
  believe, 
  been 
  noticed 
  by 
  others." 
  

  

  The 
  President 
  drew 
  the 
  attention 
  of 
  the 
  Meeting 
  to 
  the 
  Rev. 
  J. 
  F. 
  Dawson's 
  pro- 
  

   spectus 
  of 
  his 
  ' 
  Monograph 
  of 
  the 
  British 
  Geodephaga,' 
  recommending 
  the 
  proposed 
  

   work 
  as 
  worthy 
  ot 
  their 
  support, 
  and 
  stating 
  that 
  unless 
  a 
  sufficient 
  number 
  of 
  sub- 
  

   scribers 
  was 
  obtained, 
  it 
  would 
  not 
  appear.
