  Notes 
  on 
  

  

  the 
  head 
  being 
  depressed 
  by 
  bending 
  of 
  thorax. 
  In 
  a 
  few 
  

   minutes, 
  no 
  doubt 
  OAving 
  to 
  disturbance, 
  the 
  larva 
  straight- 
  

   ened 
  itself 
  and 
  the 
  small 
  size 
  of 
  the 
  remains 
  of 
  ant 
  larva 
  

   was 
  evident 
  ; 
  the 
  nest 
  contained 
  only 
  full-groAvn 
  larvae 
  and 
  

   pupae.

  L. 
  alcon, 
  figured 
  X 
  4 
  by 
  Mr. 
  Knight 
  

   (PI. 
  XXIII). 
  It 
  looked 
  11 
  or 
  12 
  mm. 
  in 
  nest, 
  but 
  is 
  14 
  mm. 
  

   when 
  out 
  of 
  nest 
  and 
  measure 
  can 
  be 
  put 
  against 
  it. 
  It 
  has 
  

   a 
  black 
  patch 
  beneath 
  mesothorax, 
  so 
  it 
  is 
  supposed 
  ail 
  is 
  not 
  

   well 
  with 
  it. 
  The 
  nest 
  is 
  now 
  a 
  rather 
  dirty 
  one. 
  Whilst 
  

   having 
  his 
  portrait 
  taken 
  the 
  larva 
  showed 
  an 
  activity 
  

   much 
  beyond 
  what 
  one 
  expected 
  from 
  its 
  quiet 
  sedentary 
  

   attitude 
  in 
  the 
  nest, 
  and 
  whilst 
  out 
  of 
  the 
  nest, 
  must 
  have 
  

   walked 
  a 
  good 
  many 
  feet. 
  

  

  June

  — 
  Looking 
  into 
  nest 
  1 
  at 
  6 
  p.m. 
  (G.M.T.) 
  this 
  

   evening, 
  larva 
  No. 
  2 
  was 
  seen 
  resting 
  on 
  the 
  floor 
  of 
  the 
  

   nest, 
  with 
  his 
  head 
  and 
  two 
  first 
  segments 
  raised 
  and 
  his 
  

   head 
  advanced 
  forwards 
  (sphinx 
  attitude), 
  and 
  an 
  ant, 
  

   also 
  with 
  her 
  front 
  raised, 
  had 
  her 
  mouth 
  and 
  that 
  of 
  the 
  

   L. 
  alcon 
  in 
  contact. 
  liuckily 
  1 
  had 
  a 
  lens 
  in 
  hand 
  and 
  

   was 
  able 
  to 
  scrutinise 
  them 
  for 
  ten 
  or 
  twelve 
  seconds, 
  

   when 
  the 
  process 
  ended, 
  the 
  ant 
  going 
  off 
  and 
  the 
  larva 
  

   dropping 
  his 
  front 
  segments 
  to 
  the 
  floor 
  of 
  the 
  nest. 
  I 
  

   directed 
  attention 
  specially 
  to 
  the 
  adjacent 
  mouths, 
  and 
  

   so 
  failed 
  to 
  note 
  precisely 
  the 
  altitude 
  by 
  which 
  the 
  head 
  

   of 
  the 
  ant 
  was 
  raised. 
  I 
  was 
  looking 
  down 
  on 
  the 
  tops 
  

   of 
  both 
  the 
  heads, 
  and 
  the 
  movements 
  of 
  the 
  mouth 
  parts 
  

   touching 
  each 
  other 
  were 
  unquestionably 
  those 
  of 
  food 
  

   being 
  passed 
  from 
  the 
  ant 
  to 
  the 
  larva, 
  viz. 
  slight 
  to 
  and 
  

   fro 
  movements 
  from 
  one 
  to 
  the 
  other, 
  with 
  adjuvant 
  

   movem.ents, 
  or 
  aspects 
  of 
  the 
  same 
  movement, 
  of 
  the 
  

   maxillae, 
  etc. 
  It 
  is 
  difficult 
  to 
  describe 
  this 
  simply 
  or 
  at 
  

   all, 
  considering 
  how 
  short 
  a 
  time 
  for 
  observation 
  was 
  

   allowed, 
  but 
  the 
  heads 
  being 
  in 
  a 
  plane 
  on 
  which 
  one 
  

   looked 
  down 
  at 
  right 
  augles, 
  and 
  the 
  two 
  heads 
  being 
  

   just 
  far 
  enough 
  apart 
  to 
  show 
  the 
  mouth 
  parts 
  of 
  both 
  

   projected 
  between 
  them, 
  their 
  movements 
  as 
  observed 
  

   could 
  clearly 
  only 
  be 
  those 
  of 
  food 
  passing 
  from 
  one 
  

   to 
  the 
  other. 
  I 
  feel, 
  however, 
  that 
  the 
  more 
  I 
  try 
  to 
  

   elaborate 
  the 
  account 
  of 
  what 
  I 
  saw, 
  the 
  less 
  I 
  shall 
  probably 
  

   convey 
  to 
  any 
  one 
  else 
  the 
  certainty 
  that 
  I 
  immediately 
  

   felt 
  that 
  the 
  ant 
  was 
  feeding 
  the 
  L. 
  alcon 
  larva.
