  BRITISH 
  LEPIDOPTEEA. 
  

  

  that 
  would 
  be 
  difficult 
  to 
  enumerate, 
  but 
  which 
  all 
  help 
  the 
  general 
  

   likeness. 
  It 
  differs 
  at 
  least, 
  in 
  the 
  following 
  points, 
  the 
  absence 
  of 
  the 
  

   lower 
  accessory 
  post-spiracular 
  group 
  of 
  hairs 
  (or 
  secondary 
  post- 
  

   spiracular 
  tubercle), 
  and 
  also 
  in 
  regard 
  to 
  the 
  greater 
  strength 
  of 
  the 
  

   spicular 
  growth 
  which 
  is 
  much 
  more 
  marked 
  than 
  in 
  S. 
  pterodactyla. 
  

   The 
  development 
  of 
  the 
  tubercles 
  has 
  also 
  not 
  advanced 
  so 
  far 
  in 
  the 
  

   direction 
  of 
  the 
  formation 
  of 
  warts, 
  the 
  instar 
  compared 
  being 
  the 
  final 
  

   one 
  (Bacot). 
  

  

  Foodplants. 
  — 
  Scabiosa 
  columbaria, 
  S. 
  arvensis, 
  S. 
  succisa 
  (Barrett), 
  

   [Galium 
  mollugo 
  (Herrich-Schaffer), 
  Scutellaria 
  gallericulata 
  {teste 
  

   Sorhagen), 
  Linaria 
  cymbalaria 
  (test. 
  French 
  authors),] 
  Saxifraga 
  

   granulata 
  (Angerer 
  teste 
  Sorhagen).] 
  One 
  would 
  like 
  confirmation 
  of 
  

   the 
  four 
  last-named 
  as 
  foodplants 
  of 
  this 
  species. 
  There 
  is 
  little 
  doubt 
  

   that 
  the 
  larva? 
  found 
  on 
  Saxifraga 
  granulata 
  were 
  those 
  of 
  Stenoptilia 
  

   pelidnodactyla 
  and 
  not 
  A. 
  bipunctidactyla. 
  The 
  various 
  statements 
  

   that 
  the 
  species 
  is 
  connected 
  with 
  Galium, 
  mollugo 
  (e.g., 
  South, 
  Ent., 
  

   xiv., 
  p. 
  52, 
  etc.) 
  are 
  to 
  be 
  traced 
  to 
  that 
  of 
  Herrich-Schaffer, 
  which 
  

   was 
  quoted 
  by 
  Sorhagen. 
  Hofmann 
  long 
  since 
  noted 
  that 
  the 
  state- 
  

   ment 
  was 
  probably 
  due 
  to 
  an 
  error 
  of 
  observation, 
  and 
  apparently 
  had 
  

   no 
  foundation 
  in 
  fact. 
  

  

  Parasites. 
  — 
  Limneria 
  ruficincta, 
  Gr. 
  (W. 
  H.B.Fletcher 
  teste 
  Barrett), 
  

   Apanteles 
  difjicilu, 
  Nees 
  (Carrington), 
  A. 
  sericeus, 
  Nees 
  (Fitch). 
  

  

  Puparitim. 
  — 
  The 
  larva? 
  of 
  the 
  spring 
  brood 
  appear 
  to 
  leave 
  their 
  

   feeding-burrows 
  for 
  pupation, 
  spinning 
  a 
  silken 
  pad 
  on 
  an 
  adjacent 
  

   object, 
  and, 
  attaching 
  themselves 
  thereto 
  by 
  the 
  cremaster, 
  change 
  to 
  

   pupa? 
  thereon. 
  Gregson 
  says 
  that 
  the 
  fullfed 
  larva 
  suspends 
  itself 
  by 
  

   the 
  tail 
  to 
  the 
  foodplant, 
  or 
  a 
  blade 
  of 
  grass, 
  or 
  any 
  other 
  object 
  it 
  may 
  

   find 
  in 
  the 
  neighbourhood 
  of 
  its 
  food, 
  the 
  pupal 
  stage 
  lasting 
  about 
  

   fifteen 
  days. 
  Buckler 
  observes 
  of 
  a 
  larva 
  that 
  suspended 
  itself 
  May 
  10th, 
  

   that 
  the 
  imago 
  did 
  not 
  emerge 
  until 
  June 
  9th. 
  South 
  observes 
  that 
  

   larva? 
  that 
  commenced 
  to 
  pupate 
  on 
  June 
  5th, 
  1885, 
  appeared 
  from 
  

   June 
  20th 
  onwards, 
  etc. 
  The 
  larva 
  attaches 
  itself 
  like 
  a 
  butterfly 
  

   larva, 
  the 
  pupa 
  hanging, 
  head 
  downwards, 
  by 
  its 
  anal 
  attachment 
  

   (Kossler) 
  ; 
  it 
  is 
  attached 
  to 
  a 
  stalk 
  of 
  the 
  foodplant 
  (Hofmann) 
  ; 
  

   fastened 
  either 
  to 
  a 
  leaf 
  or 
  stem 
  (South). 
  

  

  Pupa. 
  — 
  Long, 
  slender, 
  smooth, 
  without 
  distinct 
  nose-horn 
  or 
  

   snout 
  ; 
  green 
  in 
  colour 
  with 
  red 
  dorsal 
  line 
  ; 
  this 
  may 
  be 
  merely 
  

   indicated, 
  or 
  it 
  may 
  invade 
  most 
  of 
  the 
  pupa. 
  The 
  usual 
  colour 
  

   forms 
  are 
  : 
  a. 
  Green, 
  whitish 
  on 
  head 
  and 
  prothorax, 
  with 
  

   pink 
  line 
  from 
  middle 
  of 
  prothorax 
  to 
  cremaster, 
  where 
  the 
  red 
  

   extends 
  round 
  the 
  pupa. 
  /3. 
  Red, 
  in 
  which 
  the 
  head 
  and 
  

   prothorax 
  are 
  still 
  white, 
  the 
  mesoihorax 
  green, 
  but 
  with 
  a 
  pink 
  line 
  

   across 
  the 
  front; 
  elsewhere 
  the 
  pink 
  overlies 
  the 
  green, 
  producing 
  a 
  

   brick-red 
  subdorsally, 
  a 
  modified 
  green 
  laterally, 
  and 
  an 
  olive-green 
  

   on 
  the 
  wings 
  and 
  appendages, 
  which 
  are 
  much 
  darker 
  than 
  in 
  the 
  

   greenest 
  pupa, 
  but 
  without 
  any 
  definite 
  red 
  tint. 
  Length 
  10mm. 
  ; 
  

   antero-posterior 
  diameter 
  at 
  mesothorax 
  2mm. 
  ; 
  l*7mm. 
  from 
  3rd 
  to 
  

   5th 
  abdominal 
  segments, 
  but 
  with 
  slight 
  tapering. 
  The 
  mesothorax 
  

   is 
  swollen 
  both 
  laterally 
  and 
  dorsally, 
  and 
  gives 
  this, 
  with 
  other 
  

   Alucitid 
  pupa?, 
  much 
  suggestion 
  of 
  dipterous 
  pupa?, 
  such 
  as 
  Culex, 
  

   with 
  swollen 
  thorax. 
  The 
  swelling 
  of 
  the 
  thorax 
  is 
  assisted 
  by 
  the 
  

   subdorsal 
  flanges 
  rising 
  here 
  more 
  markedly 
  than 
  elsewhere; 
  they 
  are 
  

   somewhat 
  close 
  together, 
  and 
  form 
  a 
  double 
  hump. 
  These 
  flanges
