  I 
  have 
  placed 
  this 
  beautiful 
  insect 
  provisionally 
  in 
  Heterocampa, 
  at 
  the 
  sug- 
  

   gestion 
  of 
  my 
  friend, 
  Mr. 
  Stretch 
  ; 
  though 
  it 
  may 
  prove 
  to 
  be 
  the 
  type 
  of 
  a 
  

   new 
  genus. 
  

  

  Note. 
  — 
  I 
  wish 
  to 
  correct 
  an 
  error 
  into 
  which 
  I 
  have 
  been 
  unintentionally 
  led 
  

   in 
  No. 
  4 
  of 
  these 
  papers 
  (Proc. 
  Cal. 
  Acad. 
  Sci., 
  Feb., 
  1874). 
  I 
  have 
  therein 
  

   described, 
  as 
  a 
  new 
  species, 
  Spilosoma 
  pteridis. 
  Closer 
  investigation 
  by 
  Mr. 
  

   Stretch 
  and 
  myself 
  convinces 
  us 
  that 
  we 
  have 
  to 
  deal 
  with 
  the 
  second 
  species 
  of 
  

   -Antarclia, 
  noticed 
  by 
  Boisduval 
  ; 
  but 
  as 
  Mr. 
  Stretch 
  had 
  previously 
  arrived 
  at 
  

   the 
  conclusion 
  that 
  A. 
  vagans, 
  Bdv., 
  A.rufula, 
  Bdv., 
  and 
  A. 
  punctata, 
  Pack., 
  

   were 
  all 
  one 
  species, 
  and 
  referred 
  only 
  to 
  varieties 
  of 
  our 
  common 
  Californian 
  

   form, 
  I 
  was 
  led 
  to 
  believe 
  that 
  my 
  species 
  from 
  Vancouver 
  Island 
  was 
  unde- 
  

   scribed. 
  It 
  is 
  now, 
  however, 
  established 
  beyond 
  a 
  doubt, 
  both 
  from 
  a 
  careful 
  

   examination 
  of 
  the 
  caterpillar 
  and 
  the 
  perfect 
  insect, 
  that 
  we 
  have 
  two 
  distinct 
  

   species 
  of 
  Antarctia 
  already 
  known 
  from 
  our 
  Coast, 
  which 
  have 
  been 
  described 
  

   by 
  Dr. 
  Boisduval 
  as 
  Ant. 
  vagans, 
  and 
  Ant. 
  rufula, 
  and 
  that 
  my 
  Spilos. 
  pteridix 
  

   belongs 
  to 
  the 
  former 
  species. 
  The 
  synonomy 
  will 
  therefore 
  stand 
  thus 
  : 
  

  

  1. 
  Antarclia 
  vagans, 
  Bois., 
  Northern 
  California. 
  

   Stpilosoma 
  pttridis, 
  Hy. 
  Edw., 
  Vancouver 
  Island. 
  

  

  2. 
  Antarclia 
  rufula, 
  Bois. 
  

  

  Antarctia 
  punctata, 
  Packard, 
  San 
  Francisco 
  district. 
  

   I 
  trust 
  that 
  the 
  description 
  of 
  the 
  caterpillar 
  and 
  chrysalis, 
  which 
  I 
  have 
  ap- 
  

   pended 
  to 
  my 
  notice 
  of 
  Spilosoma 
  pteridis, 
  will 
  be 
  sufficient 
  apology 
  for 
  my 
  hav- 
  

   ing 
  unwittingly 
  encumbered 
  the 
  synonomy 
  of 
  the 
  genus.

  Egg. 
  Spherical, 
  a 
  little 
  flattened 
  above, 
  shining, 
  yellowish 
  white 
  at 
  exclu- 
  

   sion 
  — 
  attached 
  in 
  clusters 
  of 
  about 
  ten 
  or 
  twelve 
  to 
  the 
  upper 
  side 
  of 
  the 
  

   leaves. 
  The 
  third 
  day 
  the 
  apex 
  of 
  the 
  egg 
  assumes 
  a 
  dull 
  orange 
  hue, 
  after- 
  

   wards 
  changing 
  to 
  a 
  bright 
  reddish 
  purple, 
  and 
  gradually 
  to 
  a 
  duller 
  shade 
  as 
  

   the 
  young 
  larva 
  emerge. 
  The 
  eggs 
  were 
  laid 
  by 
  a 
  P 
  in 
  my 
  possession, 
  on 
  

   July 
  5th. 
  All 
  (about 
  twenty-five 
  specimens) 
  emerged 
  almost 
  simultaneously. 
  

  

  Young 
  larva. 
  Head 
  very 
  large, 
  almost 
  monstrous, 
  pale 
  olive 
  brown, 
  with 
  

   narrow 
  black 
  line 
  at 
  the 
  base. 
  Body 
  pale 
  canary 
  yellow, 
  with 
  four 
  rows 
  of 
  

   black 
  spots 
  arranged 
  longitudinally 
  in 
  lines.
