  that 
  crowd 
  round 
  it 
  in

   are 
  here 
  seen 
  well 
  spread. 
  Various 
  details 
  of 
  the 
  gland 
  itself 
  are 
  

   well 
  seen; 
  the 
  four 
  circles, 
  seen 
  in 
  all 
  honey-glands 
  of 
  Lycaenids 
  

   examined, 
  are 
  very 
  evident 
  ; 
  whatever 
  their 
  precise 
  function 
  in 
  the 
  

   gland, 
  they 
  seem 
  to 
  represent 
  the 
  four 
  dorsal 
  hairs 
  of 
  each 
  abdo- 
  

   minal 
  segment 
  (1st 
  to 
  7th), 
  here 
  replaced 
  by 
  the 
  honey-gland. 
  

   Other 
  smaller 
  circles 
  are 
  also 
  shown.

  The 
  object 
  of 
  these 
  photographs 
  is 
  to 
  show 
  that 
  the 
  full-grown 
  

   larva 
  is 
  in 
  the 
  same 
  instar 
  as 
  the 
  small 
  third 
  instar 
  larva 
  that 
  enters 
  

   the 
  ants' 
  nest. 
  Though 
  the 
  skin 
  is 
  stretclied 
  and 
  the 
  hairs 
  and 
  

   lenticles 
  are 
  more 
  widely 
  apart 
  they 
  are 
  of 
  the 
  same 
  size 
  in 
  the 
  

   large 
  and 
  in 
  the 
  small 
  larva, 
  but 
  the 
  demonstration 
  depends 
  more 
  

   particularly 
  on 
  the 
  head 
  and 
  prothoracic 
  plate 
  being 
  of 
  the 
  same 
  

   size 
  and 
  structure 
  in 
  the 
  large 
  as 
  in 
  the 
  small 
  larva.

  This 
  

   rare 
  and 
  aberrant 
  specimen 
  is 
  referred 
  to 
  in 
  the 
  following 
  paper 
  on 
  

   L. 
  euphemus 
  (p. 
  455). 
  In 
  order 
  to 
  show 
  the 
  small 
  clubbed 
  hairs 
  

   there 
  referred 
  to, 
  I 
  remounted 
  the 
  specimen 
  in 
  Canada 
  balsam, 
  

   not 
  too 
  successfully, 
  but 
  the 
  hairs 
  noted 
  are 
  shown 
  in 
  fig.

  segment,
