  seated 
  each 
  on 
  a 
  rounded 
  boss, 
  occupying 
  nearly 
  the 
  width 
  

   of 
  the 
  segment 
  beside 
  the 
  middle 
  line 
  ; 
  the 
  lateral 
  hairs 
  

   were 
  like 
  the 
  dorsal, 
  long 
  and 
  conspicuous. 
  The 
  hair-bases 
  

   are 
  very 
  closely 
  packed 
  together. 
  

  

  Aug.

  — 
  ^Third 
  and 
  fourth 
  stage 
  larvae. 
  

  

  The 
  3rd 
  stage 
  larva 
  (hardly 
  full 
  grown) 
  is 
  nearly 
  or 
  quite 
  

   4 
  mm. 
  long 
  when 
  stretched, 
  and 
  0'7 
  mm. 
  wide 
  ; 
  the 
  4th 
  

   stage 
  4' 
  5 
  to 
  5 
  mm. 
  long 
  and 
  1"5 
  mm. 
  wide. 
  

  

  The 
  3rd 
  stage 
  tapers 
  a 
  little 
  backwards 
  ; 
  the 
  4th 
  stage 
  

   remarkably 
  square, 
  the 
  two 
  sides 
  being 
  parallel, 
  only 
  the 
  

   ends 
  rounded. 
  

  

  The 
  most 
  notable 
  difference 
  between 
  the 
  two 
  is 
  in 
  the 
  

   hairs 
  in 
  3rd 
  stage 
  being 
  distinctly 
  hairs 
  and 
  sparsely 
  dis- 
  

   tributed, 
  and 
  in 
  4th 
  being 
  largely 
  hair-bases 
  closely 
  packed. 
  

   Both 
  are 
  of 
  a 
  deep 
  dark 
  pink-red, 
  almost 
  the 
  same 
  as 
  the 
  

   colour 
  of 
  the 
  head 
  of 
  Sangnisorha 
  when 
  flowering 
  is 
  over, 
  

   but 
  before 
  it 
  begins 
  to 
  get 
  very 
  dark. 
  In 
  the 
  3rd 
  stage 
  the 
  

   incisions 
  are 
  well 
  marked, 
  but 
  the 
  margins 
  on 
  dorsal 
  view 
  

   show 
  each 
  segment 
  romided 
  and 
  projecting 
  and 
  not 
  so 
  

   distinctly 
  a 
  rather 
  separate 
  square 
  projection 
  as 
  in 
  the 
  4th. 
  

   The 
  head 
  and 
  legs 
  are 
  dark, 
  but 
  not 
  quite 
  black 
  ; 
  the 
  pro- 
  

   thoracic 
  plate 
  is 
  also 
  very 
  dark. 
  

  

  In 
  the 
  4th 
  instar 
  the 
  square 
  outhne 
  when 
  the 
  larva 
  is 
  

   at 
  rest 
  is 
  notable 
  ; 
  when 
  actively 
  moving 
  there 
  is 
  a 
  little 
  

   tapering 
  towards 
  the 
  tail 
  ; 
  but 
  when 
  at 
  rest 
  the 
  prothorax 
  

   in 
  front 
  and 
  the 
  7th, 
  8th, 
  9th 
  and 
  10th 
  segments 
  behind 
  

   form 
  semicircles, 
  which 
  are 
  almost 
  identical 
  in 
  size 
  and 
  

   outline 
  ; 
  the 
  eight 
  intermediate 
  segments 
  are 
  also 
  all 
  very 
  

   similar, 
  the 
  mesothorax 
  and 
  the 
  4th, 
  5th 
  and 
  6th 
  abl. 
  being 
  

   a 
  little 
  wider 
  than 
  the 
  others, 
  the 
  1st 
  abdominal 
  smaller. 
  

  

  On 
  Aug. 
  28 
  various 
  larvae 
  are 
  noted 
  as 
  looking 
  well 
  in 
  

   ants' 
  nests 
  {Myrmica 
  scahrinodis 
  and 
  M. 
  laevinodis), 
  but 
  

   nest 
  1 
  was 
  without 
  a 
  larva, 
  and 
  a 
  new 
  larva 
  was 
  placed 
  in 
  it. 
  

  

  On 
  Aug. 
  30 
  this 
  larva 
  was 
  found 
  dead. 
  Another 
  larva 
  

   was 
  given 
  and 
  was 
  finally 
  accepted. 
  Larvae 
  in 
  other 
  nests 
  

   well, 
  all 
  near 
  the 
  brood, 
  but 
  not 
  in 
  it. 
  

  

  Sept. 
  2. 
  — 
  Yesterday 
  I 
  hunted 
  for 
  Myrmica 
  to 
  obtain 
  

   some 
  brood 
  to 
  supplement 
  some 
  of 
  my 
  nests 
  ; 
  I 
  obtained, 
  

   however, 
  only 
  a 
  small 
  quantity 
  of 
  brood, 
  which 
  I 
  left 
  in 
  a 
  

   tube, 
  putting 
  in 
  with 
  them 
  three 
  larvae 
  of 
  L. 
  eu'phemus. 
  At 
  

   about 
  1*45 
  p.m. 
  (G.M.T.), 
  having 
  previously 
  frequently 
  

   looked 
  at 
  the 
  tube 
  without 
  result, 
  I 
  found 
  one 
  of 
  the 
  L. 
  

   euphemus 
  larvae 
  eating 
  an 
  ant 
  grub. 
  The 
  latter 
  was 
  already 
  

   about 
  three-parts 
  eaten, 
  so 
  that 
  what 
  size 
  it 
  was 
  is
