  this 
  set, 
  the 
  development 
  was 
  carried 
  to 
  a 
  suppression 
  of 
  the 
  yellow 
  

   discal 
  spots 
  when 
  the 
  form 
  became 
  stygianas. 
  The 
  forms 
  connect- 
  

   ing 
  tyche 
  and 
  styijianus 
  were 
  punctarius, 
  hippolyte, 
  majestica, 
  auynsta, 
  

   tlielxiope, 
  thelxiopeia, 
  and 
  aylaopeia.

  Isoyenus 
  nubecula. 
  They 
  were 
  from 
  

   Devon, 
  Rannoch, 
  etc. 
  

  

  Mr. 
  Ashdown 
  exhibited 
  ten 
  species 
  of 
  the 
  genus 
  Cryptocephalus, 
  

   taken 
  in 
  Surrey 
  during 
  1918, 
  and 
  including

  bipnuctatiiH 
  (var.

  etc. 
  

  

  Mr. 
  Robert 
  Adkin 
  exhibited 
  series 
  of 
  Tortrices 
  bred 
  from 
  larva 
  

   which 
  he 
  had 
  found 
  feeding 
  on 
  the 
  ivy 
  growing 
  on 
  the 
  parades 
  at 
  

   Eastbourne 
  in 
  May 
  last, 
  the 
  species 
  being 
  T. 
  forsteraua, 
  T. 
  pronn- 
  

   bona, 
  and 
  T. 
  podana. 
  He 
  said 
  no 
  special 
  search 
  had 
  been 
  made 
  for 
  

   the 
  larvae, 
  he 
  had 
  simply 
  picked 
  off 
  any 
  rolled 
  or 
  spun 
  together 
  

   leaves 
  that 
  happened 
  to 
  catch 
  his 
  eye 
  as 
  he 
  passed 
  along. 
  His 
  

   object 
  in 
  making 
  the 
  exhibit 
  was 
  to 
  demonstrate 
  how 
  easily 
  one 
  

   might 
  obtain 
  several 
  species 
  of 
  this 
  somewhat 
  neglected 
  group 
  by 
  

   keeping 
  their 
  eyes 
  open 
  on 
  their 
  daily 
  perambulations. 
  

  

  Mr. 
  Bowman

  example

  4th, 
  in 
  which 
  the 
  marginal

  forewings 
  was 
  dark 
  

   suffused.

  which 
  occurs 
  in

  around 
  Warrington. 
  

  

  Mr.

  taken 
  by 
  himself, 
  showing 
  considerable 
  variation 
  in 
  size, 
  

   marking, 
  coloration,

  shape 
  of 
  wing, 
  including 
  [a)

  small 
  race 
  from 
  Til-

  compared 
  with 
  a 
  normally 
  sized 
  race 
  from

  Forest, 
  1918, 
  to 
  which 
  the 
  above 
  selected 
  specimens 
  {a) 
  

   and 
  {b) 
  belonged. 
  

  

  Mr.

  the 
  very 
  rare 
  Coleopteron 
  Ainaro- 
  

   chara 
  bonnairel 
  from 
  Box 
  Hill, 
  where 
  it
