  rare, 
  units 
  this 
  year, 
  where 
  dozens 
  could 
  have 
  been 
  taken 
  in 
  1903 
  

   (Butterfield). 
  

  

  Larva. 
  — 
  Penultimate 
  instar 
  : 
  The 
  head 
  green, 
  marbled 
  with 
  olive- 
  

   green 
  to 
  brown, 
  looking 
  dark, 
  or 
  reddish, 
  from 
  the 
  presence 
  of 
  the 
  

   following 
  dark 
  markings 
  — 
  a 
  large 
  brown 
  -black 
  patch 
  at 
  hind 
  margin, 
  

   just 
  above 
  lateral 
  line 
  ; 
  another 
  below, 
  and 
  behind, 
  the 
  ocelli, 
  which 
  are 
  

   very 
  black 
  ; 
  pale 
  brownish, 
  or 
  reddish, 
  markings 
  proceed 
  from 
  the 
  

   first 
  of 
  these, 
  at 
  its 
  inner 
  extremity, 
  down 
  centre 
  of 
  head 
  towards 
  

   clypeus, 
  and 
  from 
  its 
  lower 
  margin 
  towards 
  the 
  centre 
  of 
  the 
  cheek, 
  i.e., 
  

   the 
  marblings 
  are 
  in 
  two 
  irregular 
  longitudinal 
  streaks 
  on 
  either 
  side, 
  

   wide 
  in 
  front, 
  and 
  soon 
  fading 
  out. 
  In 
  form, 
  the 
  larva 
  is 
  fairly 
  

   cylindrical 
  (not 
  flattened 
  as 
  is 
  that 
  of 
  Aciptilia 
  galactodactyla, 
  nor, 
  

   perhaps, 
  hardly 
  so 
  round 
  as 
  is 
  that 
  of 
  Marasmarcha 
  lunaedactyla) 
  , 
  

   tapering 
  regularly 
  to 
  either 
  end 
  (the 
  longitudinal 
  section 
  being 
  

   spindle-shaped, 
  the 
  transverse 
  nearly 
  circular). 
  The 
  colour 
  is 
  

   yellowish 
  rather 
  than 
  green, 
  with 
  a 
  broad, 
  reddish, 
  dorsal 
  band, 
  

   which 
  is 
  narrowest 
  at 
  the 
  3rd 
  abdominal, 
  and 
  confined 
  to 
  the 
  dorsal 
  line 
  

   from 
  the 
  3rd 
  abdominal 
  segment 
  backwards, 
  but 
  widening 
  in 
  front, 
  so 
  

   that, 
  on 
  the 
  thorax, 
  it 
  reaches 
  tubercle 
  iv, 
  and 
  is 
  quite 
  lateral 
  as 
  well 
  

   as 
  dorsal. 
  Above, 
  and 
  behind, 
  the 
  spiracle, 
  there 
  is 
  distinct 
  sub- 
  

   segmentation, 
  so 
  that 
  each 
  segment 
  is 
  formed 
  of 
  two 
  subsegments, 
  

   the 
  anterior 
  subsegment 
  being 
  about 
  twice 
  the 
  width 
  of 
  the 
  posterior. 
  

   A 
  lateral 
  flange 
  is 
  made 
  up 
  of 
  two 
  elements, 
  one 
  below 
  the 
  spiracle, 
  

   rather 
  rounded 
  and 
  prominent, 
  the 
  other, 
  below 
  this, 
  is 
  a 
  little 
  

   narrower, 
  and 
  slopes 
  posteriorly 
  towards 
  the 
  venter. 
  Of 
  the 
  spiracles, 
  

   the 
  first 
  and 
  last 
  are 
  larger 
  than 
  the 
  others, 
  although 
  all 
  are 
  fairly 
  

   obvious, 
  raised, 
  and 
  with 
  the 
  actual 
  chitinous 
  margin 
  rather 
  golden 
  

   above. 
  The 
  anal 
  plate 
  is 
  not 
  obviously 
  a 
  plate, 
  being 
  coloured 
  

   precisely 
  as 
  the 
  rest 
  of 
  the 
  larva, 
  and 
  of 
  the 
  same 
  dull 
  surface 
  ; 
  it 
  has 
  

   three 
  hairs 
  along 
  the 
  hind 
  margin, 
  and 
  two 
  at 
  front 
  margin 
  on 
  either 
  

   side. 
  The 
  tubercles 
  on 
  the 
  abdominal 
  segments 
  are 
  — 
  i 
  (on 
  1st 
  sub- 
  

   segment) 
  with 
  1 
  long 
  hair 
  ; 
  ii 
  (on 
  2nd 
  subsegment) 
  with 
  1 
  long 
  hair, 
  

   these 
  two 
  tubercles 
  are 
  widely 
  separate 
  and 
  trapezoidally 
  placed 
  ; 
  iii 
  

   immediately 
  above 
  spiracle 
  (on 
  1st 
  subsegment), 
  with 
  1 
  long 
  hair 
  ; 
  

   below 
  the 
  spiracle, 
  iv 
  and 
  v 
  are 
  on 
  the 
  upper 
  element 
  of 
  the 
  flange, 
  1 
  

   hair 
  arising 
  from 
  each, 
  that 
  on 
  iv 
  pointing 
  backward, 
  that 
  on 
  v 
  forward, 
  

   the 
  two 
  hairs 
  arising 
  from 
  a 
  plate, 
  the 
  posterior 
  at 
  a 
  little 
  lower 
  level 
  

   than 
  the 
  anterior 
  ; 
  vi 
  on 
  lower 
  segment 
  of 
  flange, 
  with 
  1 
  backward- 
  

   directed 
  hair; 
  vii 
  carries 
  2 
  hairs 
  at 
  the 
  base 
  of 
  the 
  proleg. 
  Behind 
  the 
  

   spiracle 
  is 
  a 
  rather 
  large, 
  secondary, 
  accessory, 
  subspiracular 
  tubercle, 
  

   carrying 
  a 
  long 
  hair 
  (in 
  same 
  position 
  of 
  that 
  in 
  Cappcria 
  heterodactyla) 
  

   that 
  seems 
  to 
  be 
  more 
  than 
  an 
  ordinary 
  secondary 
  hair, 
  and 
  there 
  is 
  a 
  

   corneous 
  point 
  above 
  this. 
  Short 
  secondary 
  hairs 
  are 
  very 
  numerous, 
  

   especially 
  dorsally 
  (25 
  to 
  30 
  in 
  the 
  trapezoidal 
  area), 
  placed 
  irregularly 
  

   and, 
  usually, 
  asymmetrically, 
  and 
  are 
  whitish, 
  rather 
  clubbed 
  at 
  the 
  

   extremity, 
  with 
  serrated 
  ends 
  ; 
  they 
  are 
  about 
  T 
  l 
  o^ 
  Q 
  ^ 
  ne 
  length 
  of 
  the 
  

   primary 
  setae 
  on 
  the 
  anterior 
  trapezoidals 
  (i). 
  The 
  irregular 
  placing 
  

   of 
  some 
  of 
  these 
  secondary 
  hairs 
  is 
  notable, 
  but 
  the 
  3rd 
  abdominal 
  

   segment 
  has 
  three 
  placed 
  dorsally 
  and 
  quite 
  symmetrically, 
  and 
  

   there 
  is 
  usually 
  one 
  also 
  on 
  the 
  outside 
  of 
  i, 
  and 
  two 
  on 
  the 
  posterior 
  

   subsegment, 
  opposite 
  and 
  below 
  the 
  spiracle. 
  The 
  primary 
  setae 
  have 
  

   spindle-shaped 
  swellings 
  irregularly 
  placed, 
  that 
  appear 
  to 
  he 
  fluid, 
  

   but 
  whether 
  this 
  fluid 
  is 
  their 
  own 
  secretion, 
  or 
  that 
  of 
  the 
  glands 
  of
