  hrevicollis, 
  and 
  0. 
  rectam/ulus, 
  applied 
  well 
  to 
  our 
  British 
  

   examples, 
  and 
  separated 
  them 
  in 
  a 
  satisfactory 
  manner. 
  

   Thomson's 
  nomenclature, 
  however, 
  would 
  he 
  thought 
  prove 
  

   untenable, 
  as 
  the 
  distinguished 
  Swede 
  described 
  our 
  common 
  

   puncticollis 
  as 
  a 
  new 
  species 
  under 
  the 
  name 
  of 
  rectangulus. 
  

  

  Mr. 
  F. 
  W. 
  Frohawk 
  exhibited 
  a 
  bleached 
  specimen 
  of 
  

   Epinephele 
  janira, 
  having 
  the 
  right 
  fore 
  wing 
  of 
  a 
  creamy 
  

   white, 
  blending 
  into 
  pale 
  smoky 
  brown 
  at 
  the 
  base 
  ; 
  also 
  a 
  

   long 
  and 
  varied 
  series 
  of 
  Epinephele 
  hyperanthiis, 
  from 
  the 
  

   New 
  Forest 
  and 
  Dorking. 
  The 
  specimens 
  from 
  the 
  former 
  

   locality 
  were 
  considerably 
  darker 
  and 
  more 
  strongly 
  marked 
  

   than 
  those 
  from 
  the 
  chalk. 
  Amongst 
  the 
  specimens 
  was 
  a 
  

   variety 
  of 
  the 
  female 
  with 
  large 
  lanceolate 
  markings 
  on 
  the 
  

   under 
  side, 
  taken 
  in 
  the 
  New 
  Forest 
  in 
  July, 
  1890, 
  and 
  a 
  

   female 
  from 
  Dorking 
  with 
  large, 
  clearly 
  defined 
  white- 
  

   pupilled 
  spots 
  on 
  the 
  upper 
  side. 
  Mr. 
  Frohawk 
  further 
  

   exhibited 
  drawings 
  of 
  varieties 
  of 
  the 
  pupae 
  of 
  E. 
  hyperanthus, 
  

   and 
  also 
  a 
  large 
  specimen 
  of 
  a 
  variety 
  of 
  the 
  female 
  of 
  

   Euchloe 
  cardamines, 
  bred 
  from 
  ova 
  obtained 
  in 
  South 
  Cork, 
  

   with 
  the 
  hind 
  wings 
  of 
  an 
  ochreous-yellow 
  colour. 
  Coloured 
  

   drawings 
  illustrating 
  the 
  life-history 
  of 
  the 
  specimen 
  in 
  all 
  

   its 
  stages 
  were 
  also 
  exhibited.
