  at 
  different 
  times 
  since, 
  he 
  bad 
  heard 
  no 
  sound 
  come 
  from 
  

   that 
  pill-box. 
  Last 
  night, 
  however, 
  be 
  again 
  heard 
  the 
  

   " 
  death-watch," 
  and, 
  on 
  bringing 
  his 
  ear 
  close 
  to 
  the 
  pill- 
  

   box, 
  was 
  surprised 
  to 
  find 
  that 
  the 
  sound 
  came 
  from 
  another 
  

   quarter. 
  He 
  followed 
  up 
  the 
  sounds, 
  and 
  was 
  satisfied 
  that 
  

   they 
  came 
  from 
  a 
  little 
  wooden 
  box, 
  in 
  which 
  some 
  beetles 
  

   were 
  pinned, 
  and 
  which 
  stood 
  on 
  the 
  topmost 
  shelf 
  of 
  an 
  over- 
  

   mantel. 
  The 
  sole 
  living 
  occupant 
  of 
  the 
  box 
  was 
  Atropos 
  

   pidsatoria, 
  possibly 
  the 
  same 
  individual 
  which 
  was 
  previously 
  

   heard, 
  for 
  the 
  pill-box, 
  on 
  examination, 
  proved 
  to 
  be 
  empty. 
  

   As 
  the 
  result 
  of 
  his 
  observations, 
  Mr. 
  Gahan 
  said 
  that 
  he 
  felt 
  

   quite 
  convinced 
  that 
  Atropos 
  pidsatoria, 
  in 
  spite 
  of 
  its 
  diminu- 
  

   tive 
  size 
  and 
  the 
  softness 
  of 
  its 
  body, 
  is 
  capable 
  of 
  producing 
  

   sounds, 
  distinctly 
  audible 
  at 
  a 
  distance 
  of 
  more 
  than 
  two 
  

   yards, 
  but 
  that 
  in 
  what 
  manner 
  it 
  produces 
  the 
  sound 
  he 
  was 
  

   unable 
  to 
  ascertain. 
  

  

  Mr. 
  B. 
  A. 
  Bower 
  exhibited 
  the 
  following 
  rare 
  species 
  of 
  

   Micro-Lepidoptera 
  : 
  — 
  Spiloiwta 
  pauperana, 
  Frol. 
  ; 
  Gelechia 
  

   osseella, 
  Stn. 
  ; 
  Chrysoclysta 
  bimaculella, 
  Haw. 
  ; 
  and 
  Elachista 
  

   eingilella, 
  Fisch. 
  Lord 
  Walsingham 
  and 
  Mr. 
  Tutt 
  made 
  

   some 
  remarks 
  on

  Mr. 
  E. 
  Adkin 
  exhibited

  variety 
  of 
  Anthocharis 
  cardamines, 
  

   and 
  one 
  Sesia 
  scolimformis 
  bred 
  from 
  a 
  larva 
  found 
  at 
  Kan- 
  

   noch.

  Mr. 
  G. 
  T. 
  Baker 
  read 
  a 
  paper 
  entitled 
  " 
  Notes 
  on 
  Lycmia 
  

   (recte 
  Thecla) 
  rhymniis, 
  tengstrcemii, 
  and 
  pretiosa.'^ 
  A 
  dis- 
  

   cussion 
  followed, 
  in 
  which 
  Lord 
  Walsingham, 
  Mr. 
  Elwes, 
  

   and 
  Mr. 
  Baker 
  took 
  part. 
  

  

  Mr. 
  F. 
  Merrifield 
  read 
  a 
  paper 
  entitled 
  " 
  The 
  effects 
  of 
  

   artificial 
  temperature 
  on 
  the 
  colouring 
  of 
  Vanessa 
  iirticai 
  and 
  

   certain 
  other 
  species 
  of 
  Lepidoptera." 
  The 
  author 
  stated 
  

   that 
  he 
  had 
  already 
  proved 
  that 
  the 
  colouring 
  of 
  Selenia 
  

   illustraria, 
  in 
  both 
  the 
  spring 
  and 
  summer 
  emergences, 
  and 
  

   the 
  colouring 
  of 
  Ennomos 
  autumnaria, 
  were 
  materially 
  affected 
  

   by 
  the 
  temperature 
  to 
  which 
  the 
  pupa 
  was 
  exposed 
  in 
  its 
  

   penultimate 
  stage 
  — 
  that 
  is, 
  the 
  stage 
  immediately 
  preceding 
  

   the 
  one 
  in 
  which 
  colour 
  begins 
  to 
  show 
  externally 
  — 
  intensity 
  

   and 
  darkness 
  of 
  colouring 
  being 
  promoted 
  by 
  the 
  lower
