  The 
  Geometiae 
  are 
  easily 
  distinguished 
  by 
  their 
  size 
  and 
  slender 
  shape, 
  except 
  

   the 
  genera 
  Biston, 
  Phigalia, 
  Nyssia, 
  and 
  pait 
  oi 
  Ennonios. 
  They 
  are, 
  moreover, 
  the 
  

   most 
  active 
  pupae, 
  except 
  perhaps 
  some 
  species 
  of 
  the 
  geuus 
  Acronycla. 
  

  

  " 
  It 
  seems 
  to 
  me 
  quite 
  impossible 
  to 
  assert, 
  with 
  ar,y 
  degree 
  of 
  certainty, 
  to 
  what 
  

   subfamily 
  or 
  genus 
  of 
  Noctiiae 
  or 
  Geomelra^ 
  a 
  pupa 
  belongs, 
  or 
  to 
  assign 
  any 
  data 
  by 
  

   which 
  to 
  decide, 
  except, 
  perhaps, 
  experience 
  and 
  observation 
  ; 
  and 
  even 
  then, 
  owing 
  to 
  

   the 
  great 
  resemblance 
  of 
  many 
  species 
  to 
  each 
  other, 
  one 
  is 
  constantly 
  liable 
  to 
  error. 
  

   Tiie 
  tree 
  at 
  which 
  a 
  pupa 
  is 
  found 
  will 
  sometimes 
  assist, 
  as 
  showing 
  the 
  food 
  ; 
  but 
  

   even 
  this 
  is 
  uncertain, 
  as 
  I 
  have 
  found 
  the 
  pupa; 
  of 
  insects, 
  whose 
  larvae 
  are 
  supposed 
  

   to 
  feed 
  on 
  only 
  one 
  particular 
  tree, 
  at 
  many 
  others. 
  I 
  believe, 
  for 
  example, 
  that 
  the 
  

   larva 
  of 
  Acronycta 
  Ligustri 
  is 
  said 
  to 
  feed 
  on 
  privet 
  ; 
  I 
  never 
  took 
  it 
  there, 
  but 
  have 
  

   found 
  the 
  pupa 
  under 
  moss 
  on 
  willow, 
  beech, 
  ash, 
  and 
  oak.'' 
  

  

  Mr. 
  G. 
  R. 
  Waterhouse 
  read 
  a 
  revision 
  of 
  the 
  synonymy 
  of 
  the 
  British 
  species 
  of 
  the 
  

   genera 
  Hydrochus 
  and 
  Ochthebius, 
  founded 
  upon 
  an 
  examination 
  of 
  the 
  specimens 
  in 
  

   the 
  collection 
  of 
  the 
  late 
  Mr. 
  J. 
  F. 
  Stephens, 
  now 
  iu 
  the 
  British 
  Museum 
  ; 
  the 
  result 
  

   being 
  that 
  iu 
  the 
  majority 
  of 
  instances 
  the 
  names 
  given 
  or 
  adopted 
  by 
  Mr. 
  Stephens, 
  

   and 
  for 
  which 
  others 
  had 
  been 
  substituted 
  on 
  the 
  continent, 
  would 
  remain. 
  

  

  Mr. 
  Westvvood 
  hoped 
  that 
  advantage 
  would 
  be 
  taken 
  of 
  the 
  acquisition 
  by 
  the 
  

   Museum 
  of 
  Mr. 
  Stephens's 
  collections, 
  and 
  the 
  facilities 
  of 
  investigation 
  thereby 
  af- 
  

   forded, 
  to 
  work 
  up 
  other 
  genera 
  or 
  groups 
  of 
  our 
  indigenous 
  insects. 
  He 
  was 
  con- 
  

   vinced 
  that, 
  as 
  in 
  the 
  memoir 
  just 
  read 
  by 
  Mr. 
  Waterhouse, 
  one 
  result 
  would 
  be 
  the 
  

   vindication 
  of 
  Mr. 
  Stephens's 
  reputation 
  from 
  the 
  aspersions 
  which, 
  he 
  was 
  sorry 
  to 
  

   say, 
  had 
  recently 
  been 
  cast 
  upon 
  it 
  abroad.
