  ABSTRACT 
  OF 
  PROCEEDINGS. 
  

  

  FEBRUARY, 
  lith, 
  1918. 
  

   Mr. 
  Stanley 
  Edwards, 
  F.L.S., 
  President 
  in 
  the 
  chair. 
  

  

  The 
  death 
  of 
  Mr. 
  G. 
  Brooks, 
  a 
  member 
  of 
  the 
  Council, 
  was 
  

   announced. 
  

  

  Mr. 
  Bowman 
  exhibited 
  a 
  series 
  of 
  female 
  Hibernia 
  defoliaria 
  

   from 
  Epping- 
  Forest 
  in 
  which 
  the 
  abdomen 
  was 
  jet 
  black, 
  while 
  the 
  

   head 
  and 
  thorax 
  were 
  still 
  somewhat 
  mottled. 
  One 
  specimen 
  

   however 
  had 
  a 
  black 
  thorax 
  like 
  the 
  abdomen 
  and 
  only 
  traces 
  of 
  

   mottling 
  on 
  the 
  head. 
  They 
  were 
  taken 
  in 
  December 
  last. 
  He 
  

   stated 
  that 
  out 
  of 
  the 
  first 
  200 
  females 
  taken 
  he 
  had 
  met 
  with 
  only 
  

   4 
  black 
  aberrations, 
  i.e.,^%, 
  but 
  reaching 
  an 
  area, 
  where 
  last 
  year 
  he 
  

   had 
  met 
  with 
  this 
  form, 
  he 
  found 
  60 
  more 
  females, 
  of 
  which 
  8 
  were 
  

   of 
  the 
  dark 
  aberration, 
  thus 
  bringing 
  up 
  the 
  per 
  centage 
  to 
  4. 
  In 
  

   the 
  previous 
  year, 
  1916, 
  he 
  had 
  only 
  met 
  with 
  1% 
  of 
  the 
  aberration. 
  

   They 
  were 
  all 
  found 
  in 
  the 
  daytime 
  when 
  it 
  was 
  almost 
  impossible 
  

   to 
  meet 
  with 
  a 
  male. 
  

  

  Mr. 
  Main 
  exhibited 
  the 
  burrow 
  of 
  the 
  Coleopteron, 
  Nebria 
  

   brevicollis, 
  with 
  the 
  insect, 
  and 
  stated 
  that 
  after 
  the 
  last 
  frost 
  the 
  

   small 
  mounds 
  of 
  the 
  debris 
  thrown 
  from 
  the 
  holes 
  were 
  very 
  

   conspicuous 
  in 
  every 
  part 
  of 
  Epping 
  Forest 
  under 
  trees, 
  especially 
  

   where 
  the 
  burrow 
  was 
  made 
  in 
  the 
  red 
  sand, 
  which 
  contrasted 
  

   conspicuously 
  with 
  the 
  grey 
  general 
  surface 
  of 
  the 
  ground. 
  The 
  

   particles 
  were 
  at 
  first 
  placed 
  about 
  an 
  inch 
  from 
  the 
  mouth 
  of 
  

   the 
  burrow, 
  and 
  gradually 
  the 
  opening 
  was 
  covered, 
  after 
  which 
  

   further 
  particles 
  were 
  pushed 
  from 
  below 
  up 
  into 
  the 
  mass. 
  Mr. 
  

   Blair 
  remarked 
  that 
  the 
  mounds 
  were 
  very 
  common 
  on 
  Hampstead 
  

   Heath 
  in 
  colonies, 
  where 
  the 
  ground 
  was 
  clear 
  of 
  vegetation 
  at 
  the 
  

   foot 
  of 
  hedge, 
  wall 
  and 
  tree. 
  

  

  Mr. 
  Robert 
  Adkin 
  exhibited 
  an 
  original 
  copy 
  of 
  Christopher 
  

   Merrett's 
  "Pinax 
  Rerum 
  Naturahum 
  Britannicarum," 
  printed 
  in 
  

   London 
  in 
  1667. 
  He 
  said 
  it 
  was 
  a 
  book 
  of 
  some 
  interest 
  as 
  being, 
  

   he 
  believed, 
  one 
  of 
  the 
  earliest, 
  if 
  not 
  the 
  earliest 
  attempt 
  of 
  an 
  

   English 
  author 
  to 
  compile 
  a 
  systematic 
  catalogue 
  of 
  the 
  British
