﻿400 
  BRITISH 
  LEPIDOPTERA. 
  

  

  times 
  quite 
  wanting 
  ; 
  along 
  with 
  the 
  dark 
  markings, 
  the 
  green 
  colour 
  

   sometimes 
  becomes 
  much 
  darker; 
  one 
  specimen, 
  apparently 
  healthy, 
  is 
  

   of 
  a 
  pale 
  terra-cotta 
  colour, 
  almost 
  reddish, 
  with 
  no 
  dark 
  markings. 
  

   Length, 
  9-0mm.-9 
  # 
  5mm. 
  ; 
  thickness, 
  2-0mm.-2-2mm., 
  very 
  slightly 
  

   thickening 
  to 
  4th 
  abdominal 
  segment, 
  thence 
  tapering; 
  there 
  is 
  practi- 
  

   cally 
  no 
  "sphinx" 
  curvature, 
  but 
  the 
  face 
  is 
  not 
  at 
  all, 
  or 
  inappreci- 
  

   ably, 
  flattened, 
  so 
  that 
  the 
  pupa 
  is 
  of 
  circular 
  section 
  nearly 
  through- 
  

   out. 
  The 
  dark 
  markings 
  are 
  those 
  of 
  the 
  antennae 
  and 
  appendages, 
  

   wings, 
  dorsal 
  flanges, 
  and 
  spines 
  ; 
  dark 
  shadings 
  on 
  the 
  segments, 
  in 
  

   front 
  of, 
  and 
  between, 
  ii 
  and 
  spiracle, 
  and 
  below 
  iv-fv. 
  There 
  are 
  

   no 
  hairs 
  on 
  the 
  appendages, 
  but 
  the 
  legs, 
  antenna?, 
  and 
  wing- 
  

   veins 
  are 
  nodulated, 
  as 
  if 
  they 
  ought 
  to 
  have 
  a 
  hair 
  on 
  each 
  

   nodule. 
  The 
  median 
  vein 
  terminates 
  abruptly 
  at 
  a 
  cross-vein, 
  and 
  

   beyond, 
  two 
  veins 
  arise 
  and 
  coalesce, 
  in 
  a 
  way 
  not 
  seen 
  in 
  any 
  other 
  

   (non-plume) 
  pupa 
  that 
  I 
  have 
  seen. 
  Of 
  hairs, 
  the 
  prothorax 
  has 
  them 
  

   on 
  i, 
  ii, 
  and 
  iii; 
  the 
  mesothorax 
  has 
  a 
  dorsal 
  pair, 
  and 
  a 
  wing-basal 
  pair 
  

   (first 
  two 
  pairs 
  of 
  larval 
  hairs 
  ?) 
  ; 
  the 
  metathorax 
  has 
  one 
  on 
  i 
  (single), 
  

   and 
  two 
  hairs 
  on 
  anterior 
  outer 
  corner 
  (second 
  pair 
  of 
  larval 
  hairs?); 
  the 
  

   1st 
  abdominal 
  segment, 
  on 
  i, 
  ii, 
  iii, 
  the 
  2nd 
  abdominal 
  on 
  i, 
  ii, 
  iii, 
  iv, 
  and 
  

   v. 
  Nearly 
  all 
  these 
  hairs 
  are 
  white, 
  and 
  about 
  O-Smm.-O'Smm. 
  long 
  ; 
  

   tubercles 
  i 
  and 
  ii 
  well 
  separate 
  ; 
  iv 
  and 
  v 
  separate, 
  but 
  rather 
  close, 
  well 
  

   behind 
  the 
  spiracle, 
  and 
  very 
  nearly 
  on 
  a 
  level 
  ; 
  they 
  are 
  much 
  the 
  

   same 
  on 
  the 
  other 
  abdominal 
  segments 
  ; 
  vi 
  is 
  directed 
  backwards 
  ; 
  vii 
  

   has 
  two 
  hairs 
  at 
  a 
  level 
  — 
  equal, 
  short, 
  and 
  well 
  separate, 
  nothing 
  more 
  

   ventral. 
  The 
  chief 
  feature 
  of 
  the 
  pupa 
  (with 
  that 
  of 
  Amblyptilia 
  

   cosmodactyla), 
  is 
  the 
  remarkable 
  development 
  of 
  processes 
  in 
  connection 
  

   with 
  the 
  dorsal 
  flange 
  and 
  the 
  tubercles. 
  The 
  dorsal 
  flange 
  exists 
  on 
  

   the 
  thorax, 
  and 
  on 
  the 
  1st, 
  2nd, 
  and 
  3rd 
  abdominal 
  segments 
  (as 
  in 
  

   PlatyptiUa) 
  ; 
  on 
  the 
  3rd 
  abdominal, 
  it 
  is 
  faintly 
  marked 
  from 
  i 
  to 
  front 
  

   border 
  of 
  segment. 
  The 
  largest 
  of 
  these 
  spines 
  is 
  a 
  large 
  halbert-shaped 
  

   process 
  on 
  the 
  3rd 
  abdominal 
  segment. 
  This 
  spine 
  projects 
  dorsally 
  r 
  

   about 
  0'6mm., 
  in 
  line 
  with 
  the 
  dorsal 
  flange 
  on 
  either 
  side 
  ; 
  it 
  is 
  a 
  little 
  

   flattened 
  laterally 
  and 
  twisted 
  ; 
  it 
  projects 
  directly 
  upwards 
  (i.e., 
  dor 
  sally), 
  

   being 
  just 
  twisted 
  a 
  little 
  forward 
  on 
  its 
  base, 
  for 
  about 
  half 
  its 
  length, 
  

   it 
  then 
  gives 
  off 
  forwards 
  a 
  boss 
  which 
  carries 
  the 
  hair 
  of 
  i 
  ; 
  then 
  it 
  

   slopes 
  backwards, 
  and, 
  after 
  narrowing 
  suddenly, 
  curves 
  forwards, 
  and 
  

   ends 
  in 
  a 
  rather 
  sharp 
  point 
  ; 
  behind 
  it, 
  quite 
  separate, 
  but 
  from 
  some 
  

   points 
  of 
  view 
  seeming 
  to 
  be 
  part 
  of 
  it, 
  is 
  a 
  sharp 
  conical 
  spine 
  of 
  about 
  

   half 
  the 
  length, 
  and 
  carrying 
  ii 
  near 
  its 
  base, 
  on 
  the 
  outer 
  posterior 
  

   aspect. 
  On 
  this 
  same 
  segment 
  is, 
  behind 
  iii, 
  a 
  short 
  beehive-shaped 
  

   conical 
  eminence, 
  a 
  variation 
  apparently 
  of 
  the 
  secondary 
  hair, 
  existing 
  

   here 
  in 
  the 
  larva 
  ; 
  it 
  has 
  an 
  obsoletely-spiculated, 
  ringed, 
  aspect. 
  It 
  is 
  

   obscure 
  on 
  the 
  1st 
  and 
  2nd 
  abdominal 
  segments, 
  but, 
  on 
  the 
  4th 
  and 
  

   following 
  ones, 
  is 
  much 
  as 
  on 
  the 
  3rd 
  abdominal 
  ; 
  a 
  trace 
  of 
  a 
  similar 
  

   process 
  exists 
  between 
  iv 
  and 
  v 
  ; 
  also 
  on 
  the 
  3rd, 
  there 
  are, 
  dorsally— 
  

   (1) 
  Two 
  horns 
  that 
  are 
  in 
  line, 
  across 
  the 
  back, 
  with 
  ii, 
  and 
  dividing 
  the 
  

   space 
  into 
  three 
  equal 
  parts, 
  curved 
  backwards, 
  ringed, 
  and 
  obsoletely- 
  

   spiculated, 
  rather 
  more 
  than 
  half 
  as 
  long 
  as 
  the 
  horn 
  of 
  ii. 
  (2) 
  In 
  

   front 
  of 
  these, 
  in 
  the 
  middle 
  line, 
  is 
  a 
  similar 
  very 
  short 
  one, 
  much 
  like 
  

   the 
  one 
  behind 
  iii. 
  (3) 
  These 
  three 
  are 
  hardly 
  represented 
  on 
  the 
  1st 
  

   and 
  2nd 
  abdominal 
  segments, 
  but 
  are 
  well-marked 
  on 
  the 
  4th 
  and 
  

   following 
  segments 
  ; 
  they 
  are 
  green 
  with 
  faint 
  black 
  shading, 
  not 
  dense 
  

   black 
  like 
  the 
  flange 
  processes. 
  Tubercles 
  i 
  and 
  ii 
  carry 
  similar 
  horns
