  those 
  already 
  alluded 
  to. 
  The 
  skin-points 
  are 
  very 
  abundant 
  and 
  

   quite 
  black, 
  even 
  under 
  considerable 
  magnification. 
  The 
  prolegs 
  are 
  

   much 
  as 
  in 
  last 
  skin, 
  apparently 
  with 
  only 
  five 
  crochets 
  (the 
  claspers 
  

   with 
  seven). 
  The 
  head, 
  previously 
  black, 
  has 
  now 
  pale 
  markings. 
  

   There 
  is 
  some 
  difficulty 
  as 
  to 
  the 
  determination 
  of 
  the 
  tubercles. 
  

   The 
  tubercles, 
  however, 
  are 
  black, 
  and, 
  if 
  the 
  rule 
  may 
  be 
  taken 
  that 
  

   black 
  points 
  are 
  true 
  tubercles, 
  the 
  following 
  may 
  be 
  made 
  out 
  on 
  the 
  

   abdominal 
  segments 
  : 
  i 
  and 
  ii 
  as 
  trapezoidals, 
  i 
  rather 
  nearer 
  median 
  line 
  

   than 
  ii, 
  in 
  their 
  usual 
  positions 
  ; 
  iii 
  also 
  in 
  its 
  usual 
  position 
  ; 
  i 
  and 
  iii 
  

   on 
  the 
  1st, 
  and 
  ii 
  on 
  2nd, 
  subsegment. 
  These 
  tubercles 
  are 
  black, 
  

   with 
  a 
  long 
  pale 
  hair, 
  and 
  a 
  circle 
  of 
  shorter 
  pale 
  hairs 
  round 
  it 
  on 
  

   the 
  general 
  surface, 
  but 
  quite 
  as 
  close 
  to 
  the 
  tubercle 
  as 
  are 
  the 
  groups 
  

   of 
  hairs 
  forming 
  warts 
  on 
  the 
  larva 
  of 
  Porrittia 
  galactodactyla. 
  Below 
  the 
  

   spiracle 
  is 
  a 
  raised 
  boss, 
  green 
  in 
  colour, 
  with 
  two 
  black 
  points 
  (iv 
  and 
  

   v) 
  ; 
  this 
  is 
  placed 
  rather 
  above 
  the 
  flange, 
  which 
  is 
  marked 
  by 
  a 
  yellow 
  

   line 
  ; 
  the 
  larger 
  of 
  these 
  points 
  is 
  a 
  little 
  in 
  front 
  of 
  spiracle 
  in 
  

   position, 
  the 
  smaller 
  in 
  front 
  of, 
  and 
  slightly 
  a.bove, 
  the 
  larger. 
  In 
  

   the 
  centre 
  of 
  the 
  space 
  between 
  this 
  and 
  the 
  prolegs 
  is 
  a 
  single 
  black 
  

   point, 
  and, 
  at 
  the 
  bases 
  of 
  the 
  prolegs, 
  three 
  points, 
  placed 
  triangularly, 
  

   the 
  largest 
  being 
  above, 
  and 
  posterior 
  to, 
  the 
  others. 
  Ventrally, 
  there 
  

   is 
  one 
  minute 
  tubercle 
  on 
  either 
  side 
  of 
  the 
  medioventral 
  line, 
  where 
  

   there 
  are 
  no 
  prolegs. 
  The 
  abdominal 
  prolegs 
  carry 
  five 
  short 
  brown 
  

   hooks, 
  the 
  anal 
  bear 
  six 
  hooks 
  (Chapman).

  75-76).

  Parasites. 
  — 
  Ischnus

  Grv., 
  bred 
  from 
  a 
  pupa 
  (Kalten- 
  

   bach). 
  

  

  Puparium. 
  — 
  The 
  larva 
  appears 
  to 
  prefer 
  a 
  leaf 
  of 
  its 
  foodplant, 
  to 
  

   which 
  to 
  attach 
  itself 
  for 
  pupation, 
  rather 
  than 
  any 
  other 
  part 
  of 
  the 
  

   plant. 
  Barrett 
  says 
  that 
  it 
  " 
  attaches 
  itself 
  by 
  the 
  tail 
  to 
  the 
  surface 
  

   of 
  a 
  leaf," 
  to 
  which 
  South 
  adds 
  " 
  generally 
  on 
  one 
  of 
  the 
  terminal 
  

   leaves." 
  Bankes 
  observes 
  that, 
  of 
  four 
  pupae 
  and 
  one 
  pupating 
  larva, 
  

   found 
  on 
  June 
  22nd, 
  1904, 
  in 
  the 
  Isle 
  of 
  Purbeck, 
  two 
  only 
  were 
  on 
  

   the 
  uppersides, 
  while 
  the 
  remaining 
  three 
  were 
  on 
  the 
  undersides, 
  of 
  

   leaves 
  of 
  Ononis 
  arvensis. 
  Hofmann 
  says 
  that 
  the 
  larvae 
  prefer 
  the 
  

   stems 
  of 
  the 
  foodplant 
  for 
  pupation, 
  but 
  Speyer 
  notes 
  that, 
  near 
  Bhoden, 
  

   he 
  found 
  the 
  pupae 
  on 
  the 
  leaves 
  of 
  0. 
  repens 
  ; 
  Nolcken 
  also 
  says 
  that 
  

   they 
  are 
  usually 
  placed 
  on 
  the 
  undersides 
  of 
  the 
  leaves, 
  at 
  the 
  angles 
  of 
  

   the 
  stem, 
  or 
  in 
  similar 
  places, 
  and 
  attached 
  to 
  silken 
  webs. 
  

  

  Pupa. 
  — 
  Varies 
  from 
  8mm. 
  -10mm. 
  in 
  length, 
  the 
  average 
  between 
  

   8mm. 
  and 
  9mm. 
  ; 
  diameter 
  of 
  a 
  large 
  example, 
  at 
  4th-5th 
  abdominal 
  

   segments, 
  about 
  2mm., 
  of 
  a 
  small 
  one 
  about 
  l-5mm.-l-75mm. 
  The 
  

   pupa 
  is 
  much 
  more 
  cylindrical 
  than 
  most 
  " 
  plume 
  " 
  pupae, 
  a 
  section 
  

   would 
  be 
  nearly 
  circular, 
  whilst 
  it 
  has 
  many 
  more 
  primitive 
  characters 
  

   than 
  those 
  of 
  most 
  Alucitids 
  [Porrittia 
  galactodactyla, 
  Oidaematophorus 
  

   litliodactyla, 
  or 
  Ovendenia 
  septodactyla 
  (lienigianus)] 
  . 
  The 
  pupa 
  of 
  this 
  

   species, 
  like 
  that 
  of 
  Eucnemidophorus 
  rhododactyla, 
  shows 
  a 
  laterally 
  

   constricted 
  waist, 
  when 
  viewed 
  ventrally, 
  at 
  about 
  midway 
  up 
  the 
  

   wing-cases. 
  It 
  is 
  either 
  pale 
  green 
  in 
  colour, 
  or 
  very 
  pale 
  yellow- 
  

   brown. 
  The 
  spiracles 
  are 
  prominent, 
  but 
  only 
  slightly 
  raised.
