﻿ADKINIA 
  ZOPHODACTYLUS.

  grown) 
  : 
  Of 
  a 
  sickly 
  yellowish-green 
  colour, 
  with 
  a 
  red 
  dorsal 
  line 
  or 
  

   rather 
  band. 
  In 
  form 
  cylindrical, 
  tapering 
  rapidly 
  at 
  each 
  end, 
  from 
  

   mesothorax 
  forwards, 
  and 
  from 
  7th 
  abdominal 
  backwards. 
  Each 
  seg- 
  

   ment 
  has 
  a 
  feature, 
  common 
  in 
  "plume" 
  larvae, 
  but 
  decidedly 
  marked 
  in 
  

   this 
  species, 
  viz., 
  the 
  segment 
  is 
  cylindrical, 
  and 
  ranges 
  with 
  its 
  fellows, 
  

   but 
  the 
  incisions, 
  even 
  in 
  the 
  smaller 
  larvae, 
  have 
  little 
  of 
  the 
  appear- 
  

   ance 
  of 
  one 
  segment 
  folding 
  over 
  the 
  other, 
  but 
  each 
  is 
  a 
  wedge-shaped 
  

   groove, 
  rather 
  sharply 
  cut 
  on 
  the 
  general 
  cylindrical 
  outline, 
  which 
  is 
  

   also 
  slightly 
  affected 
  by 
  the 
  subsegmentation, 
  each 
  segment 
  being 
  

   divided 
  into 
  a 
  rather 
  large 
  anterior, 
  and 
  a 
  smaller 
  posterior, 
  subsegment, 
  

   and 
  the 
  latter 
  again 
  subdivided 
  into 
  two 
  by 
  a 
  slightly 
  less 
  marked 
  line. 
  

   As 
  to 
  colouring, 
  there 
  is 
  a 
  good 
  deal 
  of 
  difference 
  as 
  to 
  the 
  amount 
  of 
  

   red. 
  There 
  is 
  always 
  the 
  dorsal 
  band, 
  which 
  does 
  not 
  reach 
  so 
  far 
  out 
  as 
  

   tubercle 
  i. 
  Then 
  there 
  is 
  a 
  broad 
  line, 
  occupying 
  nearly 
  half 
  the 
  space 
  

   between 
  ii 
  and 
  iii, 
  which 
  is 
  often 
  wanting, 
  especially 
  in 
  older 
  larvae. 
  

   There 
  is 
  often 
  also 
  a 
  suffused 
  reddish 
  coloration 
  round 
  the 
  spiracles. 
  

   I 
  should 
  imagine 
  a 
  wholly 
  red 
  larva 
  a 
  probable 
  variety, 
  but 
  I 
  have 
  not 
  

   seen 
  one. 
  In 
  a 
  larva 
  in 
  which 
  the 
  subdorsal, 
  normally 
  red, 
  line 
  is 
  of 
  an 
  

   olive-green, 
  its 
  upper 
  and 
  lower 
  margins 
  are 
  bounded 
  by 
  a 
  yellowline, 
  the 
  

   lower 
  one 
  being 
  waved, 
  arched 
  up 
  over 
  the 
  spiracle, 
  and 
  downwards 
  on 
  

   the 
  2nd 
  of 
  the 
  three 
  subsegments. 
  It 
  has 
  the 
  appearance 
  of 
  resulting 
  

   from 
  subcutaneous 
  material 
  (fat 
  bodies 
  ?) 
  ; 
  a 
  little 
  way 
  below 
  iv 
  and 
  v 
  

   is 
  another 
  pale 
  line, 
  almost 
  white 
  rather 
  than 
  yellow. 
  On 
  the 
  red 
  dorsal 
  

   band 
  is 
  a 
  diamond-mark 
  on 
  each 
  segment, 
  formed 
  by 
  four 
  yellowish 
  

   lines 
  ; 
  the 
  two 
  front 
  ones 
  are 
  on 
  the 
  latter 
  half 
  of 
  the 
  1st 
  subsegment, 
  

   and 
  diverge 
  backwards, 
  the 
  other 
  two, 
  on 
  the 
  posterior 
  subsegments, 
  

   reverse 
  this 
  arrangement, 
  and 
  fall 
  a 
  little 
  short 
  of 
  the 
  posterior 
  

   margin 
  of 
  the 
  segment. 
  There 
  is 
  also 
  a 
  curious 
  brown 
  spot, 
  just 
  

   outside 
  each 
  external 
  angle. 
  The 
  tubercles 
  are, 
  i, 
  with 
  a 
  hair 
  

   (0-3mm.) 
  directed 
  slightly 
  forwards, 
  and 
  a 
  short 
  posterior 
  hair 
  ; 
  it 
  

   is 
  just 
  behind 
  the 
  middle 
  of 
  the 
  1st 
  subsegment 
  ; 
  ii, 
  on 
  the 
  middle 
  

   of 
  the 
  2nd 
  (or 
  3rd) 
  subsegment, 
  has 
  an 
  upright 
  hair, 
  such 
  as 
  that 
  on 
  

   i, 
  and 
  one 
  short 
  posterior 
  hair; 
  iii 
  also 
  has 
  one 
  long 
  hair 
  and 
  a 
  posterior 
  

   shorter 
  one 
  ; 
  iv 
  and 
  v 
  are 
  apparently 
  very 
  close 
  together, 
  but 
  not 
  

   conjoined, 
  the 
  anterior 
  being 
  a 
  little 
  upper, 
  length 
  about 
  O'Smm. 
  ; 
  

   viis 
  low 
  down 
  at 
  the 
  posterior 
  margin 
  of 
  the 
  segment, 
  with 
  a 
  backward- 
  

   directed 
  hair 
  ; 
  below 
  this 
  are 
  three 
  hairs 
  above 
  the 
  proleg 
  ; 
  one 
  of 
  

   these 
  does 
  not 
  seem 
  to 
  be 
  one 
  of 
  the 
  usual 
  three 
  in 
  this 
  position, 
  but 
  

   is 
  rather 
  higher 
  up. 
  To 
  revert 
  to 
  the 
  subsegmentation- 
  the 
  subseg- 
  

   ments 
  extend 
  down 
  to 
  below 
  iv 
  and 
  v; 
  the 
  2nd 
  subsegment 
  curling 
  

   round 
  under 
  the 
  1st 
  and 
  3rd 
  subsegments, 
  preserving 
  its 
  distinctness, 
  

   however, 
  and 
  all 
  ending 
  in 
  a 
  marked 
  "flange 
  " 
  ; 
  below 
  this 
  is 
  another 
  

   flange, 
  with 
  an 
  anterior 
  and 
  posterior 
  prominence 
  ; 
  the 
  anterior 
  

   has 
  a 
  secondary 
  hair 
  or 
  two, 
  the 
  posterior 
  carries 
  vi. 
  There 
  is 
  

   again 
  a 
  sulcus 
  below 
  this 
  flange, 
  as 
  well 
  as 
  above, 
  dividing 
  it 
  from 
  

   the 
  subspiracular 
  (carrying 
  iv 
  and 
  v) 
  flange. 
  The 
  spiracles 
  are 
  

   hemispherical 
  brown 
  bosses, 
  with 
  the 
  spiracular 
  opening 
  ai 
  top. 
  

   The 
  general 
  skin-surface 
  is 
  finely 
  spiculated. 
  Secondary 
  hairs 
  are 
  

   variable; 
  they 
  are 
  very 
  short, 
  and 
  either 
  white 
  or 
  brown-black. 
  The 
  

   latter 
  are 
  always 
  present 
  on 
  the 
  dorsal 
  rod 
  line, 
  and 
  sometimes 
  on 
  the 
  

   lower 
  one; 
  in 
  one 
  larva, 
  there 
  is 
  one, 
  and 
  sometimes 
  two. 
  between 
  (or 
  

   slightlyabove)tubercesivandv. 
  One 
  larva 
  has 
  no 
  white 
  secondary 
  hairs; 
  

   another 
  has 
  a 
  little 
  row 
  along 
  the 
  anterior 
  and 
  posterior 
  borders 
  oi 
  each
