  doubtful, 
  but 
  the 
  width 
  of 
  segments 
  on 
  the 
  portion 
  remain- 
  

   ing 
  suggested 
  a 
  half 
  -grown 
  one. 
  The 
  L. 
  euphemus 
  was 
  on 
  

   the 
  side 
  of 
  the 
  tube, 
  so 
  that 
  its 
  under 
  surface 
  was 
  easily 
  

   examined. 
  It 
  was 
  straight, 
  in 
  its 
  usual 
  resting 
  attitude, 
  

   and 
  the 
  remaining 
  portion 
  of 
  ant 
  grub 
  stretched 
  from 
  the 
  

   front 
  of 
  the 
  L. 
  eiqjhemus 
  to 
  the 
  end 
  of 
  its 
  thorax 
  ; 
  it 
  had 
  a 
  

   pulsating 
  movement, 
  showing 
  that 
  the 
  jaws 
  of 
  the 
  Lycaena 
  

   were 
  at 
  work. 
  Almost 
  at 
  once 
  it 
  was 
  seen 
  that 
  the 
  legs 
  of 
  

   the 
  Lycaena 
  were 
  appearing 
  round 
  the 
  edge 
  of 
  the 
  ant 
  grub 
  

   remains, 
  and 
  very 
  soon 
  they 
  had 
  it 
  between 
  them 
  and 
  were 
  

   actively 
  manipulating 
  it 
  to 
  bring 
  it 
  more 
  directly 
  to 
  the 
  

   head 
  of 
  the 
  larva. 
  In 
  a 
  few 
  minutes 
  the 
  ant 
  grub 
  was 
  so 
  

   reduced 
  that 
  the 
  head 
  of 
  the 
  larva 
  could 
  be 
  seen, 
  with 
  the 
  

   jaws 
  actively 
  at 
  work; 
  the 
  whole 
  observation 
  did 
  not 
  last 
  

   more 
  than 
  a 
  few 
  minutes, 
  and 
  it 
  may 
  be 
  understood 
  that 
  

   the 
  eating 
  was 
  rapidly 
  done. 
  

  

  The 
  next 
  immediate 
  stage 
  was 
  that 
  only 
  a 
  bit 
  of 
  skin 
  of 
  

   the 
  ant 
  remained, 
  and 
  this 
  was 
  then 
  eaten, 
  almost 
  rather 
  

   swallowed 
  than 
  eaten, 
  as 
  it 
  seemed 
  to 
  be 
  drawn 
  in 
  bit 
  by 
  

   bit, 
  without 
  the 
  bits 
  being 
  se|)arated. 
  During 
  this 
  last 
  

   stage, 
  the 
  portion 
  of 
  ant 
  grub 
  was 
  too 
  small 
  to 
  be 
  touched 
  

   by 
  the 
  legs, 
  and 
  lay 
  as 
  it 
  were 
  in 
  the 
  hollow 
  beneath 
  the 
  

   prothorax, 
  possibly 
  held 
  there 
  against 
  the 
  side 
  of 
  the 
  tube. 
  

   So 
  soon 
  as 
  it 
  had 
  disappeared, 
  it 
  was 
  evident 
  that 
  the 
  head 
  

   of 
  the 
  L. 
  euphemus 
  was 
  retracted 
  within 
  the 
  hood 
  of 
  the 
  

   prothorax, 
  so 
  that 
  the 
  margin 
  of 
  the 
  cavity 
  formed 
  by 
  the 
  

   hood 
  seemed 
  to 
  be 
  against 
  the 
  glass 
  and 
  the 
  head 
  freely 
  

   moved 
  within. 
  It 
  continued 
  a 
  sort 
  of 
  eating 
  movement, 
  but 
  

   quickly 
  changed 
  to 
  moving 
  round, 
  almost 
  rapidly, 
  hcking 
  

   the 
  inside 
  of 
  the 
  hood, 
  which 
  may 
  well 
  have 
  been 
  moistened 
  

   by 
  the 
  fluids 
  of 
  the 
  half-eaten 
  grub 
  which 
  must 
  have 
  touched 
  

   it 
  ; 
  this 
  continued 
  till 
  the 
  surface 
  all 
  round 
  had 
  been 
  gone 
  

   over 
  several 
  times 
  and 
  the 
  first 
  pair 
  of 
  legs 
  were 
  also 
  licked. 
  

   Though 
  the 
  larva 
  has 
  no 
  tongue, 
  I 
  say 
  hcked, 
  as 
  the 
  move- 
  

   ments 
  had 
  all 
  the 
  aspect, 
  and 
  I 
  should 
  say 
  for 
  practical 
  

   purposes, 
  all 
  the 
  effects 
  of 
  licking. 
  It 
  then 
  settled 
  down 
  in 
  

   its 
  ordinary 
  resting 
  position, 
  and 
  was 
  in 
  the 
  same 
  place 
  and 
  

   attitude 
  half 
  an 
  hour 
  later. 
  

  

  Sept. 
  6. 
  — 
  Four 
  larvae 
  in 
  nest 
  3 
  (M. 
  laevinodis) 
  are 
  6 
  to 
  

   7 
  mm. 
  long, 
  they 
  rest 
  on 
  the 
  side 
  of 
  the 
  nest, 
  all 
  four 
  head 
  

   downwards. 
  The 
  small 
  bosses 
  on 
  each 
  side 
  of 
  the 
  dorsum 
  

   are 
  marked, 
  and 
  especially 
  on 
  the 
  2nd 
  and 
  3rd 
  thoracic 
  they 
  

   are 
  very 
  large, 
  a 
  fact 
  that 
  is 
  accentuated 
  by 
  the 
  lowness 
  

   and 
  narrowness 
  of 
  the 
  1st 
  abdominal.
