﻿all 
  pupated 
  and 
  hatched 
  by 
  July 
  20th 
  ; 
  eight 
  to 
  nine 
  days 
  

   only 
  being 
  spent 
  in 
  the 
  pupal 
  state. 
  I 
  exhibit 
  larvae 
  and 
  

   pupae 
  and 
  bred 
  insects 
  and 
  the 
  "pupal 
  skin. 
  

  

  Both 
  the 
  larva 
  and 
  pupa 
  differ 
  in 
  various 
  ways 
  from 
  

   those 
  of 
  C. 
  1-jpunctata, 
  but 
  we 
  need 
  not 
  go 
  into 
  that 
  

   here. 
  

  

  In 
  1908 
  I 
  wrote 
  : 
  " 
  My 
  present 
  view 
  is 
  that 
  these 
  beetles 
  

   seek 
  the 
  nests 
  of 
  Formica 
  riifa 
  for 
  hibernation, 
  and 
  leave 
  in 
  

   the 
  spring 
  or 
  early 
  summer." 
  I 
  endeavoured 
  to 
  settle 
  this 
  

   point 
  this 
  winter. 
  I 
  brought 
  a 
  number 
  of 
  the 
  beetles 
  home 
  

   on 
  August 
  27th 
  and 
  established 
  them 
  on 
  the 
  small 
  fir-tree 
  

   planted 
  in 
  my 
  large 
  tufa 
  observation 
  nest. 
  Of 
  course, 
  my 
  

   Aphids 
  died 
  off, 
  but 
  I 
  found 
  the 
  beetles 
  would 
  feed 
  with 
  the 
  

   ants 
  on 
  the 
  honey 
  supplied 
  for 
  the 
  latter. 
  I 
  may 
  mention 
  

   that 
  a 
  number 
  of 
  them 
  passed 
  the 
  whole 
  winter 
  on 
  the 
  fir- 
  

   tree, 
  and 
  sides 
  of 
  the 
  nest 
  (I 
  exhibit 
  two 
  of 
  them 
  taken 
  off 
  

   the 
  small 
  fir-tree 
  to-day), 
  but 
  a 
  number 
  disappeared. 
  On 
  

   Feb, 
  29th 
  this 
  year 
  I 
  dug 
  up 
  the 
  whole 
  nest, 
  all 
  the 
  ants 
  being 
  

   down 
  below, 
  but 
  only 
  found 
  one 
  Lady-bird 
  right 
  beneath 
  

   the 
  debris 
  with 
  the 
  ants. 
  

  

  On 
  Feb. 
  28th 
  I 
  had 
  been 
  down 
  to 
  Weybridge 
  and 
  dug 
  up 
  

   a 
  rufa 
  nest 
  in 
  nature 
  there. 
  The 
  ants 
  were 
  right 
  below 
  the 
  

   hillock 
  in 
  earth 
  chambers 
  some 
  2| 
  feet 
  down, 
  and 
  I 
  found 
  

   one 
  Lady-bird 
  with 
  them; 
  dormant, 
  but 
  quite 
  alive. 
  There 
  

   were 
  others 
  as 
  usual 
  on 
  the 
  fir-trees 
  above 
  the 
  nests. 
  

  

  I 
  fear 
  this 
  is 
  not 
  sufficient 
  evidence 
  to 
  prove 
  my 
  point, 
  

   and 
  one 
  must 
  still 
  ask 
  why 
  is 
  C. 
  distincta 
  only 
  found 
  with 
  

   F. 
  rufa, 
  when 
  it 
  could 
  as 
  easily 
  find 
  plenty 
  of 
  its 
  food 
  away 
  

   from 
  ants' 
  nests 
  ? 
  

  

  Another 
  point 
  which 
  may 
  be 
  a 
  factor 
  in 
  the 
  problem 
  is 
  the 
  

   fact 
  that 
  Coccinella 
  distincta 
  is 
  often 
  found 
  in 
  company 
  with 
  

   Clythra 
  i-'punctata, 
  the 
  latter 
  beetle 
  passing 
  its 
  earlier 
  stages 
  

   in 
  the 
  rufa 
  nests. 
  I 
  stated 
  as 
  long 
  ago 
  as 
  1900 
  that 
  I 
  con- 
  

   sidered 
  the 
  Clythra 
  to 
  be 
  a 
  mimic 
  of 
  the 
  Coccinella 
  [Ent. 
  

   Rec. 
  xii, 
  p. 
  174 
  (1900)]. 
  This 
  is 
  a 
  case 
  of 
  Miillerian 
  mimicry 
  

   as 
  I 
  suggested 
  might 
  be 
  the 
  case 
  in 
  1901 
  [Trans. 
  Ent. 
  Soc. 
  

   Lond., 
  1901, 
  367]. 
  Experiments 
  with 
  Clythra 
  at 
  the 
  Zoo- 
  

   logical 
  Gardens 
  proved 
  it 
  to 
  be 
  distasteful 
  to 
  various 
  birds 
  and 
  

   insectivora 
  [Trans. 
  Ent. 
  Soc. 
  Lond., 
  1902, 
  p. 
  17]. 
  It 
  might
