  Lycaena 
  euphemus.

  L. 
  euphemus, 
  said 
  to 
  be 
  in 
  five 
  heads 
  of 
  Sanguisorba 
  ; 
  when 
  

   they 
  arrived 
  all 
  the 
  larvae 
  were 
  on 
  the 
  paper 
  containing 
  

   the 
  heads, 
  the 
  latter 
  fairly 
  fresh 
  (had 
  been 
  posted 
  2()th). 
  The 
  

   largest 
  of 
  the 
  larvae 
  was 
  lethargic, 
  seemed 
  dead, 
  but 
  had 
  a 
  

   firm 
  tone 
  that 
  siiggested.it 
  was 
  stmmed 
  by 
  travelUng 
  or 
  

   more 
  likely 
  sickening 
  for 
  moult. 
  The 
  larvae 
  were 
  reported 
  

   by 
  Mr. 
  Powell 
  to 
  be 
  in 
  3rd 
  instar, 
  and 
  that 
  they 
  

   underwent 
  another 
  moult. 
  The 
  other 
  four 
  larvae 
  were 
  

   replaced 
  on 
  heads 
  of 
  Sanguisorba 
  and 
  were, 
  so 
  far 
  as 
  

   appeared, 
  all 
  right. 
  

  

  Aug. 
  23. 
  — 
  The 
  largest 
  larva 
  (about 
  4 
  mm.) 
  had 
  clearly 
  

   been 
  laid 
  up 
  for 
  moult, 
  as 
  this 
  morning 
  the 
  old 
  skin 
  had 
  

   been 
  moved 
  a 
  little, 
  some 
  air 
  under 
  it 
  and 
  tracheas 
  slightly 
  

   withdrawn, 
  the 
  larva 
  still 
  immovable, 
  sUghtly 
  curved 
  . 
  Two 
  

   of 
  the 
  other 
  larvae 
  were 
  still 
  wandering 
  and 
  two 
  invisible, 
  

   supposed 
  buried 
  in 
  heads. 
  One 
  of 
  the 
  wandering 
  larvae 
  

   was 
  offered 
  heads 
  of 
  Poterium, 
  this 
  was 
  not 
  accepted. 
  

  

  Aug. 
  24. 
  — 
  -This 
  morning 
  the 
  large 
  larva, 
  which 
  had 
  made 
  

   no 
  move 
  last 
  evening, 
  had 
  cast 
  its 
  skin, 
  which 
  remained 
  

   fully 
  distended 
  ; 
  the 
  larva 
  itself 
  had 
  spun 
  a 
  few 
  threads 
  

   to 
  form 
  a 
  resting-place. 
  Shortly 
  after 
  it 
  was 
  found 
  on 
  the 
  

   move 
  with 
  a 
  fluid 
  globule 
  on 
  the 
  honey-gland. 
  It 
  was 
  

   placed 
  in 
  nest 
  of 
  M. 
  scabrinodis 
  ; 
  the 
  ants 
  paid 
  little 
  atten- 
  

   tion 
  to 
  it. 
  It 
  was 
  moved 
  to 
  a 
  small 
  collection 
  of 
  ants 
  and 
  

   brood, 
  but 
  a 
  quarter 
  of 
  an 
  hour 
  later 
  the 
  ants 
  had 
  removed 
  

   the 
  brood 
  and 
  left 
  the 
  larva 
  stranded 
  alone. 
  Later 
  they 
  

   frequently 
  examined 
  it, 
  apparently 
  sometimes 
  biting 
  it, 
  

   but 
  without 
  injury. 
  It 
  secreted 
  various 
  supplies 
  of 
  honey, 
  

   which 
  was 
  lapped 
  up 
  by 
  passing 
  ants, 
  but 
  never 
  sought 
  for 
  

   and 
  not 
  found 
  by 
  the 
  ants 
  actually 
  examining 
  it. 
  

  

  Aug. 
  25.^ 
  — 
  This 
  larva 
  was 
  found 
  dead, 
  a 
  httle 
  shrunk, 
  

   amongst 
  debris 
  ; 
  it 
  had 
  been 
  bitten 
  as 
  evidenced 
  by 
  marks, 
  

   but 
  the 
  skin 
  did 
  not 
  appear 
  to 
  have 
  been 
  pierced. 
  

  

  Of 
  the 
  four 
  smaller 
  larvae, 
  two 
  were 
  dead, 
  one 
  was 
  

   crawling 
  on 
  the 
  glass, 
  and 
  one 
  was 
  half 
  buried 
  in 
  a 
  head 
  of 
  

   Sanguisorba 
  with 
  some 
  frass 
  behind 
  it. 
  The 
  wandering 
  

   one 
  was 
  offered 
  the 
  best 
  remaining 
  Sanguisorba 
  and 
  heads 
  of 
  

   Poterium. 
  Later 
  its 
  head 
  was 
  buried 
  in 
  the 
  Poterium 
  ; 
  but 
  

   there 
  was 
  no 
  definite 
  indication 
  that 
  it 
  was 
  eating. 
  

  

  The 
  larvae 
  are 
  dark 
  red, 
  almost 
  identical 
  with 
  the 
  colour 
  

   of 
  the 
  Sanguisorba 
  heads 
  when 
  just 
  past 
  flowering. 
  The 
  

   smaller 
  ones 
  are 
  about 
  3 
  to 
  3*5 
  mm. 
  long; 
  the 
  larger 
  were 
  

   about 
  4 
  mm., 
  but 
  would 
  probably 
  have 
  been 
  a 
  little 
  more 
  

   stretched. 
  When 
  it 
  had 
  moulted, 
  the 
  dorsal 
  hairs 
  were
