  Mr. 
  G. 
  H. 
  Cornish, 
  of 
  Plumstead 
  Common, 
  was 
  elected 
  a 
  

   member. 
  

  

  Mr. 
  Ashdown 
  exhibited 
  numerous 
  species 
  of 
  Lepidoptera 
  taken 
  

   by 
  him 
  in 
  Surrey 
  during 
  the 
  past 
  year, 
  inchiding 
  Hylojthila 
  bicolo- 
  

   rana, 
  Fyi/ara 
  cnrtula, 
  Hiiiiera 
  pennaiia, 
  and 
  a 
  fine 
  aberration 
  of 
  

   Pieiis 
  nafii 
  in 
  which 
  the 
  veins 
  were 
  strongly 
  marked, 
  the 
  apical 
  

   blotch 
  of 
  the 
  forewings 
  was 
  absent, 
  with 
  the 
  spots 
  reduced 
  in 
  size 
  

   and 
  uniform 
  in 
  shape. 
  

  

  Mr. 
  Buckstone 
  exhibited 
  two 
  series 
  of 
  jh/riades 
  thetis 
  [hellaniHs) 
  

   second 
  brood, 
  and 
  communicated 
  the 
  following 
  note 
  : 
  — 
  

  

  " 
  One 
  of 
  the 
  series 
  consists 
  of 
  specimens 
  taken 
  near 
  Brighton 
  in 
  

   September 
  last, 
  and 
  the 
  other 
  of 
  representatives 
  of 
  a 
  large 
  number 
  of 
  

   specimens 
  taken 
  in 
  the 
  Dorking 
  district 
  of 
  Surrey 
  during 
  the 
  last 
  

   sixteen 
  years. 
  

  

  " 
  The 
  Brighton 
  specimens 
  are 
  smaller 
  than 
  those 
  from 
  Dorking, 
  

   while 
  the 
  females 
  are 
  of 
  a 
  darker 
  colour, 
  and 
  the 
  undersides 
  of 
  the 
  

   males 
  greyer. 
  

  

  " 
  The 
  blue 
  form 
  of 
  the 
  female, 
  so 
  plentiful 
  most 
  seasons 
  at 
  Dork- 
  

   ing, 
  was 
  not 
  found 
  at 
  Brighton, 
  although 
  two 
  of 
  the 
  specimens 
  

   exhibited 
  do 
  certainly 
  show 
  a 
  considerable 
  number 
  of 
  blue 
  scales, 
  

   but 
  in 
  no 
  way 
  approaching 
  the 
  extreme 
  forms 
  one 
  finds 
  in 
  the 
  

   Surrey 
  locality, 
  some 
  of 
  which 
  are 
  shown." 
  

  

  Mr. 
  H. 
  Main 
  exhibited 
  an 
  Anopheles 
  species 
  from 
  Eastbourne, 
  

   where 
  it 
  had 
  occurred 
  in 
  considerable 
  abundance 
  during 
  the 
  

   autumn. 
  

  

  Mr. 
  P. 
  W. 
  Frohawk 
  exhibited 
  (1) 
  Plebeius 
  arjon, 
  very 
  pale 
  ex- 
  

   amples, 
  very 
  dark 
  with 
  the 
  forewings 
  underside 
  immaculate, 
  and 
  a 
  

   slightly 
  striated 
  specimen. 
  (2) 
  Ariria 
  medon 
  (astrarche) 
  with 
  pale 
  

   yellow 
  marginal 
  markings. 
  (H) 
  Polijomniatus 
  icarus, 
  a 
  female 
  with 
  

   pale 
  yellow 
  marginal 
  markings. 
  

  

  Mr. 
  Edwards 
  exhibited 
  some 
  Nematoid 
  worms 
  from 
  a 
  cat, 
  named 
  

   for 
  him 
  by 
  Mr. 
  Hirst, 
  of 
  the 
  Nat. 
  Hist. 
  Museum, 
  Belascaris 
  cati, 
  

   Schrank, 
  or 
  Ascaris 
  mystax, 
  Zeder. 
  According 
  to 
  Neumann, 
  1914, 
  

   the 
  <? 
  measures 
  from 
  3-6 
  centimetres, 
  and 
  the 
  J 
  measures 
  from 
  

   4-10 
  centimetres. 
  The 
  worms 
  do 
  not 
  affect 
  the 
  health 
  of 
  the 
  cat. 
  

   He 
  also 
  exhibited 
  a 
  fungus, 
  Peziza 
  ventriculosa, 
  one 
  of 
  the 
  Asconiy-
