  tions 
  of 
  others 
  the 
  form 
  with 
  a 
  black 
  thorax, 
  which 
  is 
  absent 
  from 
  

   my 
  cabinet. 
  The 
  name 
  totini<im 
  has 
  been 
  suggested 
  for 
  this 
  entirely 
  

   black 
  form, 
  as 
  iimcolor, 
  Homb., 
  under 
  which 
  name 
  it 
  is 
  said 
  to 
  be 
  

   sold, 
  is 
  said 
  to 
  apply 
  to 
  a 
  form 
  in 
  which 
  all 
  black 
  spots 
  are 
  absent 
  

   with 
  the 
  exception 
  of 
  the 
  costal 
  marginal 
  spot 
  nearest 
  the 
  base. 
  

  

  Although 
  I 
  feel 
  it 
  incumbent 
  upon 
  me 
  to 
  apologise 
  for 
  nob 
  deal- 
  

   ing 
  with 
  this 
  interesting 
  genus 
  in 
  a 
  more 
  comprehensive 
  manner, 
  

   I 
  hope 
  that 
  what 
  I 
  have 
  said 
  may 
  have 
  been 
  of 
  some 
  interest 
  and 
  

   will 
  lead 
  to 
  a 
  valuable 
  discussion. 
  

  

  Mr, 
  Hugh 
  Main 
  exhibited, 
  in 
  one 
  of 
  his 
  special 
  observation 
  cages, 
  

   the 
  burrow 
  of 
  Atypiis 
  affinis, 
  the 
  British 
  representative 
  of 
  the 
  "trap- 
  

   door 
  spider," 
  which 
  is 
  fairly 
  common 
  in 
  some 
  parts 
  of 
  Epping 
  

   Forest, 
  and 
  was 
  noted 
  some 
  years 
  ago 
  as 
  occurring 
  on 
  Hampstead 
  

   Heath 
  by 
  the 
  late 
  Mr. 
  Enoch, 
  who 
  made 
  many 
  observations 
  on 
  the 
  

   habits 
  of 
  the 
  species. 
  Mr. 
  Main 
  pointed 
  out 
  that 
  the 
  burrow 
  was 
  

   lengthened 
  by 
  a 
  tube 
  made 
  of 
  the 
  debris, 
  and 
  often 
  covered 
  by 
  

   lichen 
  extending 
  for 
  several 
  inches. 
  This 
  structure 
  was 
  held 
  by 
  

   guy-ropes 
  of 
  web 
  attached 
  to 
  neighbouring 
  objects 
  such 
  as 
  blades 
  

   of 
  grass. 
  He 
  stated 
  that 
  all 
  the 
  work 
  was 
  done 
  at 
  night. 
  

  

  Mr. 
  Turner 
  exhibited 
  specimens 
  of 
  a 
  local 
  spider 
  from 
  Dorking, 
  

   Epeira 
  vnibratica, 
  which 
  was 
  almost 
  jet 
  black 
  in 
  colour 
  with 
  two 
  

   conspicuous 
  light 
  coloured 
  spots 
  on 
  the 
  underside 
  of 
  the 
  abdomen. 
  

   They 
  were 
  met 
  with 
  on 
  their 
  cocoons 
  on 
  a 
  tarred 
  close 
  fence, 
  facing 
  

   south. 
  These 
  cocoons 
  were 
  of 
  white 
  threads 
  covered 
  with 
  scraps 
  of 
  

   the 
  tar, 
  and 
  thus 
  rendered 
  more 
  or 
  less 
  inconspicuous, 
  especially 
  

   when 
  the 
  spider 
  was 
  resting 
  flattened 
  down 
  on 
  them. 
  

  

  Mr. 
  Frohawk 
  exhibited 
  four 
  females 
  of 
  Lijcuna 
  avion 
  from 
  three 
  

   different 
  localities, 
  showing 
  divergence 
  in 
  ground 
  colouring. 
  Two 
  

   bred 
  specimens 
  from 
  Cornwall 
  of 
  a 
  much 
  brighter 
  silvery-blue, 
  the 
  

   hindwings 
  having 
  only 
  two 
  moderately-sized 
  spots. 
  One 
  from 
  the 
  

   Cotswolds 
  without 
  spots 
  on 
  the 
  hindwings, 
  and 
  one 
  from 
  Barnwell 
  

   Wold 
  having 
  large 
  spots 
  on 
  the 
  forewings, 
  large 
  discoidals 
  and 
  four 
  

   well 
  emphasised 
  spots 
  on 
  the 
  hindwings. 
  The 
  two 
  latter 
  were 
  of 
  a 
  

   dull 
  purplish 
  blue. 
  

  

  Mr. 
  Frohawk 
  also 
  exhibited 
  Fieris 
  brassica', 
  a 
  specimen 
  with 
  white 
  

   streaks 
  crossing 
  the 
  black 
  apical 
  portions, 
  similar 
  to 
  the 
  specimens 
  

   described 
  and 
  figured 
  in 
  the 
  "Entomologist," 
  March, 
  1918, 
  p. 
  57; 
  

   the 
  butterfly 
  was 
  in 
  perfect 
  condition, 
  and 
  was 
  captured 
  in 
  July, 
  

   1900, 
  at 
  Southend, 
  by 
  Mr. 
  F. 
  G. 
  Whittle 
  ; 
  he 
  also 
  exhibited 
  a 
  bred 
  

   specimen 
  with 
  asymmetrical 
  markings.
