  Mr, 
  Bunnett 
  exhibited 
  a 
  very 
  pale 
  example 
  of 
  Miltochrista 
  vnniata 
  

   from 
  Crowborough, 
  several 
  species 
  of 
  Coleoptera, 
  and 
  a 
  species 
  of 
  

   mite, 
  Trowbidiiim. 
  

  

  Mr. 
  F. 
  B. 
  Carr 
  exhibited 
  series 
  of 
  Abraxas 
  si/lvata 
  {uhiiata) 
  from 
  

   Chalfont, 
  with 
  a 
  minimum 
  of 
  markings 
  rather 
  faint, 
  from 
  

   Delamere 
  with 
  a 
  maximum 
  of 
  markings 
  much 
  intensified, 
  and 
  from 
  

   Wye 
  with 
  forms 
  intermediate 
  as 
  to 
  markings. 
  Among 
  the 
  Chalfont 
  

   specimens 
  were 
  several 
  in 
  which 
  the 
  hindwings 
  were 
  devoid 
  of 
  

   markings 
  except 
  at 
  the 
  anal 
  angle. 
  

  

  SEPTEMBER 
  12th, 
  1918. 
  

   Mr. 
  R. 
  Adkin, 
  Vice-President, 
  in 
  the 
  chair. 
  

  

  Mr. 
  Ashdown 
  exhibited 
  a 
  short 
  series 
  of 
  both 
  sexes 
  of 
  the 
  

   Homopteron, 
  Ledra 
  aurita, 
  from 
  Hants 
  and 
  Surrey, 
  and 
  pointed 
  out 
  

   several 
  females 
  in 
  which 
  the 
  horns 
  were 
  more 
  developed 
  than 
  

   those 
  of 
  the 
  male. 
  He 
  also 
  showed 
  the 
  larvae 
  at 
  different 
  stages 
  

   of 
  growth. 
  

  

  Mr. 
  Blair 
  exhibited 
  specimens 
  of 
  the 
  two 
  very 
  similar 
  beetles, 
  

   Coccinella 
  distincta 
  and 
  C. 
  septem 
  punctata, 
  from 
  Weybridge, 
  the 
  

   former 
  of 
  which 
  was 
  always 
  in 
  association 
  with 
  the 
  ant 
  Formica 
  

   rufa, 
  and 
  pointed 
  out 
  the 
  distinction 
  of 
  the 
  two 
  species 
  as 
  follows: 
  — 
  

  

  " 
  Coccinella 
  1-functata, 
  L., 
  and 
  C. 
  distincta, 
  Fald. 
  Though 
  at 
  first 
  

   sight 
  very 
  closely 
  resembling 
  one 
  another, 
  with 
  the 
  arrangement 
  of 
  

   the 
  black 
  spots 
  on 
  the 
  elytra 
  almost 
  identical, 
  these 
  two 
  species 
  

   present 
  several 
  more 
  or 
  less 
  sharply 
  defined 
  points 
  of 
  difference 
  that 
  

   make 
  their 
  distinction 
  comparatively 
  easy. 
  The 
  more 
  important 
  

   of 
  these 
  may 
  be 
  expressed 
  as 
  follows 
  : 
  — 
  

  

  C. 
  1 
  -punctata. 
  

   Convexity 
  sloping, 
  feebly 
  round- 
  

   ed 
  ; 
  lateral 
  margins 
  of 
  elytra 
  

   completely 
  visible 
  from 
  above* 
  

   apical 
  declivity 
  sloping. 
  

  

  Elytra 
  with 
  lateral 
  borders 
  

   thickened 
  in 
  anterior 
  half, 
  very 
  

   fine 
  behind. 
  

  

  Episternum 
  and 
  epimeron 
  of 
  

   metathorax 
  black; 
  i^e., 
  no 
  con- 
  

  

  C 
  distincta. 
  

  

  Convexity 
  strongly 
  rounded 
  ; 
  

   lateral 
  margins 
  of 
  elytra 
  usual- 
  

   ly 
  concealed 
  from 
  above 
  by 
  the 
  

   overhanging 
  convexity 
  of 
  disc, 
  

   extreme 
  apical 
  declivity 
  verti- 
  

   cal. 
  

  

  Elytra 
  with 
  lateral 
  borders 
  very 
  

   fine 
  and 
  even 
  throughout. 
  

  

  Epimeron 
  and 
  posterior 
  end 
  of 
  

   episternum 
  of 
  metathorax
