  BRITISH 
  LEPLDOPTERA. 
  

  

  requires 
  verification. 
  Feeding 
  in 
  the 
  blossoms 
  at 
  the 
  same 
  time, 
  

   he 
  discovered 
  the 
  larvae 
  of 
  Nemotois 
  scabiosellus 
  (Ent. 
  Mo. 
  Mag., 
  

   xviii., 
  p. 
  183 
  ; 
  Wien. 
  Ent. 
  Zeitschr., 
  1864, 
  p. 
  201) 
  ; 
  in 
  Silesia, 
  

   Wocke 
  found 
  the 
  larvae 
  in 
  April, 
  in 
  Succisa 
  ]jratensis, 
  and 
  again 
  in 
  

   the 
  summer; 
  whilst, 
  in 
  Wiirttemberg, 
  Steudel 
  and 
  Hofmann 
  record 
  

   it 
  in 
  May 
  in 
  the 
  shoots, 
  and 
  in 
  July-August 
  in 
  the 
  blossoms, 
  of 
  S. 
  

   pratensis. 
  Hofmann 
  observes 
  that 
  he 
  found 
  the 
  larvae, 
  on 
  July 
  21st, 
  

   1895, 
  in 
  the 
  interior 
  of 
  the 
  hollow 
  flower-heads 
  of 
  Scabiosa 
  columbaria, 
  

   the 
  flowers 
  offering 
  no 
  outward 
  indication 
  of 
  the 
  larvae 
  within 
  ; 
  when 
  

   fullfed, 
  the 
  larvae 
  were 
  seen 
  sitting 
  on 
  the 
  blossoms, 
  feeding 
  thereon, 
  

   and 
  boring 
  holes 
  from 
  the 
  outside 
  through 
  the 
  separate 
  florets. 
  

   According 
  to 
  Sorhagen, 
  " 
  the 
  larva 
  lives 
  in 
  May, 
  July, 
  and 
  September, 
  

   on 
  Scabiosa 
  succisa, 
  S. 
  arvensis, 
  Scutellaria 
  galericulata, 
  Linaria 
  

   cymbalaria 
  (in 
  France), 
  Galium 
  mollugo 
  (Herrich-Schaffer), 
  Saxifraga 
  

   granulata 
  (Angerer), 
  in 
  spun 
  -up 
  flowers 
  or 
  shoots." 
  Hartmann 
  also 
  

   notes 
  that 
  the 
  larva 
  is 
  said 
  to 
  feed 
  on 
  Saxifraga 
  granulata 
  in 
  April- 
  

   May, 
  and 
  September; 
  and 
  Koch 
  on 
  Galium 
  mollugo 
  in 
  mid- 
  September. 
  

   No 
  doubt, 
  Hartmann's 
  reference 
  is 
  to 
  Stenoptilia 
  pelidnodactyla 
  , 
  the 
  

   larva 
  of 
  which 
  feeds 
  on 
  Saxifraga 
  granulata, 
  whilst, 
  of 
  Koch's 
  record, 
  

   evidently 
  copied 
  from 
  Herrich-Schaffer, 
  one 
  would 
  like 
  confirmation. 
  

  

  Larva. 
  — 
  First 
  instar 
  (newly-hatched) 
  : 
  Barely 
  1mm. 
  long. 
  Head 
  

   about 
  same 
  width 
  as 
  body, 
  which 
  tapers 
  a 
  little 
  towards 
  tail. 
  The 
  

   head 
  dark, 
  body 
  whitish, 
  or 
  faintly 
  yellowish 
  (or 
  colourless). 
  Pro- 
  

   thoracic 
  plate 
  large, 
  faintly 
  tinted. 
  Amongst 
  a 
  number 
  of 
  ordinary 
  

   hairs 
  on 
  head 
  (about 
  0-01 
  5mm. 
  long) 
  are 
  two 
  from 
  the 
  eye-region, 
  very 
  

   long, 
  at 
  least 
  four 
  times 
  the 
  length 
  of 
  the 
  others 
  (about 
  O06mm.), 
  and 
  

   standing 
  forwards 
  like 
  horns 
  or 
  antennae. 
  Two 
  lateral 
  hairs 
  on 
  the 
  

   prothorax 
  are 
  about 
  as 
  long, 
  and 
  several 
  on 
  the 
  9th 
  and 
  10th 
  

   abdominal 
  segments 
  ; 
  the 
  rest 
  are 
  about 
  0-03mm. 
  in 
  length, 
  stiff 
  

   and 
  straight, 
  slender, 
  and 
  faintly 
  clubbed 
  at 
  tip. 
  The 
  tubercles 
  

   are 
  faint 
  black 
  dots, 
  the 
  hairs 
  colourless, 
  or 
  faintly 
  tinted 
  towards 
  

   the 
  tip 
  ; 
  each 
  tubercle 
  has 
  only 
  one 
  seta 
  or 
  hair 
  ; 
  i 
  and 
  ii 
  are 
  placed 
  

   about 
  ^ 
  length 
  of 
  segment 
  apart, 
  and 
  rather 
  farther 
  than 
  this 
  from 
  

   middle 
  line, 
  ii 
  being 
  decidedly 
  further 
  out 
  than 
  i 
  ; 
  the 
  setae 
  upright, 
  

   that 
  from 
  i 
  inclined 
  slightly 
  forwards, 
  from 
  ii 
  rather 
  backwards, 
  

   iii 
  has 
  a 
  seta 
  directed 
  forwards; 
  iv 
  and 
  v 
  are 
  well 
  separate, 
  the 
  

   forward 
  one 
  (v) 
  higher, 
  and 
  with 
  a 
  shorter 
  hair, 
  about 
  three-fifths 
  of 
  

   that 
  on 
  iv, 
  which 
  is 
  about 
  equal 
  to 
  the 
  seta 
  on 
  ii 
  or 
  iii 
  ; 
  the 
  long 
  hairs 
  

   on 
  the 
  9th 
  and 
  10th 
  abdominal 
  segments 
  are 
  apparently 
  iii 
  or 
  v 
  ; 
  on 
  

   the 
  prothorax, 
  the 
  long 
  hair 
  is 
  subspiracular. 
  The 
  spiracles 
  on 
  an 
  

   elevation. 
  The 
  prolegs 
  on 
  longish 
  pedicels, 
  with 
  three 
  minute 
  hooks 
  ; 
  

   the 
  anal 
  claspers 
  larger, 
  hooks 
  also 
  larger, 
  but 
  apparently 
  only 
  two 
  

   hooks, 
  a 
  third 
  merely 
  vestigial 
  (Chapman, 
  August 
  29th, 
  1904). 
  

   Second 
  instar 
  ; 
  Head 
  rounded, 
  black, 
  highly 
  polished, 
  and 
  partly 
  

   retractile 
  beneath 
  the 
  skinfolds 
  of 
  the 
  prothorax. 
  The 
  scutellum 
  

   large 
  ; 
  anal 
  plate 
  small, 
  both 
  very 
  dark, 
  but 
  not 
  quite 
  as 
  dark 
  as 
  head. 
  

   The 
  body 
  is 
  of 
  nearly 
  even 
  thickness, 
  only 
  slightly 
  tapering 
  to 
  anus; 
  the 
  

   segmental 
  divisions 
  sharp, 
  but 
  not 
  particularly 
  deep. 
  The 
  colour 
  is 
  a 
  

   dull 
  pinkish, 
  and 
  the 
  skin-surface 
  very 
  rough, 
  owing 
  to 
  spicules. 
  

   Hairs 
  rather 
  short 
  and 
  tapering, 
  not 
  serrated. 
  Tubercles 
  on 
  the 
  meta- 
  

   and 
  mesothorax 
  are 
  — 
  i 
  and 
  ii 
  side 
  by 
  side, 
  i 
  the 
  inner, 
  and 
  slightly 
  to 
  the 
  

   front 
  ; 
  iii 
  and 
  iv 
  on 
  the 
  same 
  plate, 
  v 
  having 
  a 
  longer 
  hair 
  with 
  a 
  small 
  

   one 
  below 
  and 
  behind 
  it 
  ; 
  vii 
  has 
  two 
  hairs.
