  the 
  ocelli 
  brownish 
  -black. 
  The 
  true 
  legs 
  are 
  of 
  the 
  same 
  semi- 
  

   transparent 
  greenish-grey 
  tint 
  as 
  the 
  head, 
  the 
  terminal 
  hooks 
  beiDg 
  

   black, 
  but, 
  laterally 
  to 
  the 
  legs 
  on 
  either 
  side, 
  and 
  below 
  the 
  marginal 
  

   tubercle, 
  is 
  a 
  red- 
  brown 
  patch 
  (? 
  slightly 
  chitinous) 
  on 
  each 
  of 
  the 
  

   thoracic 
  segments, 
  a 
  somewhat 
  similar, 
  but 
  smaller, 
  patch 
  being 
  placed 
  

   higher 
  up, 
  directly 
  above 
  the 
  marginal 
  tubercles. 
  With 
  the 
  exception 
  

   of 
  a 
  trace 
  of 
  the 
  lower 
  one 
  on 
  either 
  side 
  of 
  the 
  venter 
  of 
  the 
  1st 
  

   abdominal 
  segment, 
  these 
  brown 
  patches 
  are 
  confined 
  to 
  the 
  latero- 
  

   ventral 
  area 
  of 
  the 
  thoracic 
  segments. 
  The 
  remainder 
  of 
  the 
  venter 
  

   is 
  more 
  or 
  less 
  of 
  the 
  greenish 
  ground 
  colour, 
  but, 
  under 
  a 
  good 
  lens, 
  

   the 
  ventral 
  area 
  of 
  the 
  thoracic 
  segments, 
  the 
  bases 
  of 
  the 
  true 
  legs, 
  

   the 
  fronts 
  of 
  the 
  abdominal 
  segments, 
  the 
  bases 
  of 
  the 
  prolegs, 
  as 
  well 
  as 
  

   the 
  venter 
  of 
  the 
  9th 
  and 
  10th 
  abdominal 
  segments, 
  are 
  semi-transparent, 
  

   and 
  very 
  glassy-looking. 
  The 
  prolegs 
  are 
  long 
  and 
  slender 
  (and 
  there 
  is 
  

   some 
  sign 
  of 
  a 
  slight 
  "loop" 
  when 
  the 
  larva 
  is 
  walking 
  hurriedly). 
  The 
  

   hooks 
  on 
  the 
  prolegs 
  are 
  few 
  in 
  number, 
  and 
  exceedingly 
  small 
  ; 
  the 
  

   anal 
  prolegs 
  are 
  of 
  the 
  same 
  pale, 
  semi-transparent, 
  greenish 
  colour 
  as 
  

   the 
  others, 
  the 
  hooks 
  are 
  also 
  very 
  minute. 
  I 
  was 
  interested 
  to 
  see 
  

   a 
  larva 
  use 
  the 
  anal 
  prolegs 
  as 
  pincers, 
  by 
  means 
  of 
  which 
  it 
  was 
  seen 
  

   to 
  throw 
  a 
  frass 
  pellet 
  to 
  a 
  considerable 
  distance 
  from 
  the 
  body. 
  On 
  those 
  

   segments, 
  which 
  do 
  not 
  carry 
  prolegs, 
  a 
  tiny 
  tubercular 
  point 
  carries 
  one 
  

   or 
  two 
  hairs 
  in 
  the 
  proleg 
  position. 
  All 
  the 
  short, 
  irregularly-scattered, 
  

   secondary 
  hairs 
  appear 
  to 
  be 
  bluntly 
  bifid, 
  and 
  like 
  the 
  short 
  hairs 
  on 
  

   the 
  tubercular 
  warts 
  ; 
  the 
  1st 
  and 
  2nd 
  abdominal 
  segments 
  have 
  a 
  very 
  

   large 
  number 
  of 
  secondary 
  hairs 
  on 
  the 
  venter 
  (Tutt. 
  April, 
  29th, 
  1904). 
  

   Final 
  imtar 
  (fullgrown) 
  : 
  Yellowish-green 
  in 
  colour, 
  looking 
  glaucous 
  

   or 
  hoary, 
  from 
  the 
  abundant 
  hairs, 
  and 
  paler, 
  round, 
  large 
  warts, 
  from 
  

   which 
  they 
  arise 
  ; 
  short 
  and 
  thick, 
  8mm. 
  long, 
  l-8mm. 
  wide; 
  small 
  

   ochreous 
  head 
  with 
  brown 
  markings, 
  overhung 
  by 
  a 
  thick 
  curtain 
  of 
  

   hairs 
  from 
  margin 
  of 
  prothorax 
  ; 
  it 
  tapers 
  in 
  either 
  direction 
  from 
  the 
  

   1st 
  abdominal 
  segment, 
  but 
  the 
  change 
  is 
  slight 
  in 
  the 
  first 
  six 
  abdo- 
  

   minal 
  segments; 
  there 
  is 
  a 
  green 
  dorsal 
  line 
  (dorsal 
  vessel?), 
  but 
  

   otherwise 
  the 
  colouring 
  is 
  very 
  uniform, 
  and 
  there 
  are 
  no 
  markings 
  

   except 
  on 
  thoracic 
  segments, 
  where 
  there 
  are 
  small 
  brown 
  patches 
  below 
  

   tubercles 
  v 
  + 
  vi, 
  and, 
  on 
  mesothorax, 
  in 
  front 
  of 
  i 
  — 
  {— 
  ii 
  also. 
  The 
  

   hairs 
  are 
  white; 
  the 
  tubercles 
  pale, 
  except 
  a 
  darker 
  shade 
  at 
  base 
  of 
  

   principal 
  hairs 
  ; 
  the 
  tubercles 
  carry 
  numerous 
  secondary 
  hairs, 
  but 
  

   these 
  are 
  much 
  longer 
  than 
  the 
  secondary 
  hairs 
  scattered 
  over 
  the 
  skin- 
  

   surface. 
  The 
  tubercles 
  i 
  and 
  ii, 
  on 
  the 
  abdomen, 
  form 
  one 
  large 
  round 
  

   wart, 
  with 
  two 
  primary 
  hairs, 
  distinguishable 
  from 
  the 
  others 
  by 
  being 
  

   tinted 
  with 
  sepia 
  basally, 
  and 
  with 
  a 
  dark 
  ring 
  of 
  origin 
  ; 
  they 
  are 
  smooth 
  

   and 
  pointed, 
  that 
  representing 
  i 
  being 
  in 
  front 
  of, 
  and 
  inside, 
  that 
  repre- 
  

   senting 
  ii, 
  about 
  1-Omni. 
  long, 
  ii 
  being 
  about 
  2-0mm. 
  long; 
  these, 
  and 
  

   other 
  primary 
  hairs, 
  are 
  marked 
  with 
  rings 
  like 
  those 
  of 
  a 
  porcupine, 
  

   there 
  being 
  only 
  one, 
  two, 
  or 
  three, 
  to 
  a 
  hair; 
  several 
  secondary 
  hairs 
  are 
  

   long, 
  smooth, 
  and 
  pointed, 
  and 
  even 
  ringed 
  like 
  the 
  primary, 
  but-, 
  basally, 
  

   they 
  are 
  abundantly 
  distinct 
  ; 
  then 
  there 
  are 
  very 
  definite 
  secondary 
  

   hairs, 
  to 
  the 
  number 
  of 
  twelve 
  to 
  fifteen, 
  of 
  various 
  lengths 
  down 
  to 
  

   04mm. 
  ; 
  the 
  smaller 
  they 
  are, 
  the 
  more 
  they 
  are 
  thickened 
  at 
  the 
  end; 
  

   this 
  thickening 
  is 
  gradual, 
  and 
  generally 
  ends 
  in 
  two 
  or 
  three 
  divisions 
  

   or 
  points; 
  tubercle 
  iii 
  may 
  bo 
  described 
  in 
  similar 
  tonus 
  to 
  i 
  + 
  ii, 
  

   except 
  that 
  it 
  has 
  only 
  one 
  primary 
  hair 
  ; 
  iv-fv, 
  again, 
  carries 
  two 
  

   primaries, 
  the 
  upper 
  ono 
  (that 
  representing' 
  v) 
  in 
  front 
  ; 
  it 
  is 
  othei
