  There 
  are 
  also 
  two 
  (not 
  so 
  far 
  as 
  can 
  be 
  seen 
  three, 
  as 
  in 
  later 
  

   instars) 
  hairs 
  at 
  the 
  base 
  of 
  each 
  proleg, 
  a 
  posterior 
  outer 
  and 
  

   longer, 
  and 
  a 
  shorter 
  inner 
  rather 
  in 
  front 
  ; 
  vi 
  not 
  seen 
  ; 
  on 
  segments 
  

   without 
  prolegs 
  are 
  two 
  hairs 
  in 
  line 
  transversely, 
  vii 
  and 
  ? 
  viii. 
  The 
  

   longer 
  hairs 
  (those 
  on 
  ii 
  and 
  iii) 
  are 
  nearly 
  as 
  long 
  as 
  the 
  larva 
  

   is 
  wide, 
  0'23mm. 
  and 
  0*16mm., 
  that 
  on 
  i 
  is 
  about 
  0'06mm. 
  and 
  on 
  v 
  

   about 
  0'04mm. 
  long, 
  that 
  on 
  iv 
  is, 
  however, 
  longer, 
  0-1 
  5mm. 
  All 
  

   the 
  spiracles 
  are 
  well 
  raised 
  on 
  tall 
  rounded 
  bases. 
  The 
  prolegs 
  

   are 
  on 
  rather 
  tall 
  slender 
  pedicels, 
  and 
  have 
  three 
  rather 
  large 
  

   hooks 
  each. 
  The 
  hairs 
  on 
  the 
  anal 
  plate 
  are 
  difficult 
  to 
  locate 
  

   exactly, 
  but, 
  besides 
  shorter 
  ones, 
  there 
  are 
  four 
  very 
  long 
  ones, 
  

   O20mm. 
  and 
  024mm. 
  long. 
  The 
  claspers 
  have 
  four 
  hooks, 
  possibly 
  

   five, 
  as 
  they 
  are 
  not 
  very 
  clearly 
  seen, 
  being 
  easily 
  retracted 
  (Chapman, 
  

   July 
  3rd, 
  1904). 
  The 
  newly-emerged 
  larva 
  has 
  a 
  somewhat 
  flattened 
  

   body 
  tapering 
  gradually 
  to 
  a 
  rather 
  pointed 
  anus. 
  The 
  head 
  is 
  large 
  and 
  

   broad, 
  carried 
  horizontally, 
  very 
  polished 
  in 
  appearance, 
  in 
  colour 
  dark 
  

   brown. 
  Both 
  the 
  anal 
  plate 
  and 
  scutellum 
  are 
  in 
  evidence, 
  the 
  latter 
  

   paler 
  than 
  the 
  head 
  but 
  still 
  noticeably 
  brown, 
  the 
  former 
  very 
  pale, 
  

   almost 
  of 
  the 
  same 
  hue 
  as 
  the 
  general 
  body 
  tint, 
  that 
  is 
  a 
  bright, 
  but 
  

   pale, 
  semitransparent 
  green. 
  The 
  segments 
  are 
  distinctly 
  marked. 
  The 
  

   hairs 
  are 
  bright 
  brown 
  in 
  a 
  strong 
  light, 
  tapering, 
  and, 
  I 
  think, 
  quite 
  

   simple 
  ; 
  at 
  any 
  rate, 
  I 
  cannot 
  discern 
  any 
  thorns 
  ; 
  those 
  on 
  the 
  head 
  

   are 
  short, 
  but 
  on 
  the 
  body 
  they 
  are 
  much 
  longer. 
  The 
  skin 
  is 
  shiny 
  

   without 
  spicular 
  growth. 
  Tubercles 
  i 
  and 
  ii 
  are 
  set 
  in 
  pairs 
  transversely, 
  

   on 
  meta- 
  and 
  mesothorax 
  ; 
  their 
  bases 
  are 
  well 
  apart, 
  but 
  the 
  space 
  

   between 
  the 
  two 
  pairs 
  centrally 
  gives 
  them 
  the 
  appearance 
  of 
  being- 
  

   close 
  together, 
  iii 
  and 
  iv 
  are 
  close 
  together 
  but 
  not 
  touching 
  ; 
  v 
  is 
  

   alone 
  in 
  usual 
  position. 
  On 
  the 
  abdominal 
  segments 
  i 
  and 
  ii 
  are 
  

   set 
  in 
  markedly 
  trapezoidal 
  position, 
  iii 
  carries 
  a 
  long 
  single 
  hair, 
  iv 
  

   and 
  v, 
  beneath 
  spiracle, 
  are, 
  as 
  usual, 
  close 
  together. 
  There 
  are, 
  

   of 
  course, 
  no 
  secondary 
  hairs 
  in 
  this 
  skin 
  (Bacot, 
  July 
  5th, 
  3 
  905). 
  

   Final 
  instar 
  (f 
  ullgrown) 
  : 
  This 
  larva 
  is 
  very 
  like 
  that 
  of 
  Platyptilia 
  gono- 
  

   dactyla 
  in 
  general 
  aspect 
  ; 
  but 
  differs 
  especially 
  in 
  having 
  no 
  secondary 
  

   hairs(i.e., 
  skin-points). 
  The 
  head 
  is 
  light 
  brown. 
  Thereis 
  adeep 
  brown 
  

   prothoracic 
  plate, 
  divided 
  in 
  the 
  middle 
  line, 
  with 
  the 
  usual 
  six 
  hairs 
  on 
  

   either 
  side 
  and 
  a 
  slightly 
  darker 
  puckered 
  spot, 
  where 
  some 
  plume 
  

   larvae 
  have 
  a 
  black 
  mark 
  ; 
  the 
  prothoracic 
  spiracle 
  is 
  placed 
  in 
  a 
  hardly 
  

   raised 
  conical 
  plate, 
  of 
  about 
  thrice 
  the 
  diameter 
  of 
  the 
  spiracle 
  

   itself 
  ; 
  this 
  plate 
  looks 
  nearly 
  black 
  ; 
  in 
  front 
  of 
  the 
  spiracle 
  is 
  a 
  

   large 
  plate 
  with 
  three 
  hairs, 
  the 
  lower 
  (front) 
  one 
  largest. 
  On 
  the 
  

   meso- 
  and 
  metathorax, 
  there 
  are, 
  on 
  each 
  side, 
  three 
  plates 
  at 
  regular 
  

   intervals 
  down 
  the 
  middle 
  of 
  segments, 
  each 
  of 
  these 
  tubercular 
  plates 
  

   with 
  two 
  hairs 
  ; 
  and 
  much 
  low 
  T 
  er 
  a 
  fourth 
  plate 
  with 
  two 
  hairs 
  at 
  base 
  

   of 
  legs. 
  The 
  first 
  plate 
  is 
  nearly 
  divided 
  into 
  two. 
  Behind 
  and 
  

   between 
  the 
  second 
  and 
  third 
  is 
  another 
  plate 
  with 
  one 
  hair. 
  Of 
  

   the 
  four 
  plates 
  the 
  first 
  has 
  the 
  hairs 
  slightly 
  trapezoidal, 
  i.e., 
  the 
  

   second 
  a 
  little 
  further 
  back. 
  The 
  second 
  has 
  them 
  reversed, 
  

   i.e., 
  the 
  second 
  rather 
  forward, 
  the 
  third 
  has 
  them 
  in 
  line 
  with 
  

   the 
  zone 
  of 
  the 
  segment, 
  i.e., 
  in 
  a 
  transverse 
  line, 
  the 
  fourth 
  

   has 
  them 
  one 
  in 
  front 
  of 
  the 
  other. 
  On 
  the 
  abdominal 
  segments 
  

   i 
  and 
  ii 
  are 
  placed 
  trapezoidally, 
  about 
  one-third 
  of 
  the 
  width 
  of 
  

   the 
  segment 
  apart, 
  iii 
  normal, 
  iv 
  and 
  v 
  on 
  a 
  single 
  plate 
  well 
  below 
  the 
  

   spiracle, 
  tolerably 
  close 
  together 
  and 
  the 
  anterior 
  (v) 
  upper; 
  vi 
  has
