  So 
  far 
  as 
  we 
  are 
  able 
  to 
  judge 
  from 
  the 
  descriptions 
  at 
  

   hand, 
  the 
  larval 
  forms 
  also 
  agree; 
  and 
  it 
  is 
  quite 
  an 
  interesting 
  

   fact 
  that 
  the 
  European 
  variety 
  which 
  is 
  destitute 
  of 
  the 
  

   yellow 
  lateral 
  stripe, 
  has 
  also 
  its 
  counterpart 
  in 
  the 
  example 
  

   found 
  at 
  Schoharie, 
  of 
  which 
  the 
  description 
  has 
  been 
  given, 
  

   and 
  in 
  another 
  taken 
  at 
  Sharon 
  Springs 
  by 
  Mr. 
  von 
  Meske. 
  

  

  From 
  an 
  example 
  of 
  our 
  eastern 
  form 
  sent 
  by 
  me 
  to 
  Mr. 
  

   Stretch, 
  of 
  San 
  Francisco, 
  he 
  has 
  identified 
  it 
  as 
  his 
  ffi. 
  Cali- 
  

   forniea. 
  If, 
  however, 
  the 
  sketch 
  of 
  the 
  larva 
  made 
  by 
  Dr. 
  

   Behr 
  and 
  the 
  information 
  which 
  he 
  gives 
  of 
  the 
  larva, 
  be 
  cor- 
  

   rect, 
  then 
  there 
  is 
  a 
  possibility 
  that 
  a 
  comparison 
  of 
  additional 
  

   examples 
  of 
  "iV. 
  Calif 
  ornica" 
  may 
  show 
  it 
  to 
  be 
  distinct. 
  

   The 
  figure 
  of 
  the 
  larva, 
  as 
  reproduced 
  by 
  Mr, 
  Stretch, 
  is 
  cer- 
  

   tainly 
  quite 
  different 
  in 
  its 
  appearance 
  from 
  any 
  of 
  those 
  

   which 
  have 
  come 
  under 
  my 
  observation. 
  

  

  It 
  will 
  be 
  seen 
  that 
  I 
  have 
  included 
  in 
  the 
  synonymy 
  of 
  this 
  

   species, 
  references 
  to 
  the 
  Ph. 
  Bomb, 
  tremula 
  of 
  Linnaeus 
  and 
  

   Clerck, 
  as 
  probably 
  identical 
  with 
  it. 
  This 
  opinion 
  is 
  held 
  by 
  

   several 
  of 
  the 
  best 
  European 
  Lepidopterists, 
  who 
  claim 
  that 
  

   the 
  same 
  species 
  was 
  twice 
  described 
  by 
  Linnaeus. 
  Others, 
  

   as 
  Staudinger, 
  entertain 
  the 
  belief 
  that 
  the 
  dictcea 
  of 
  Linnaeus 
  

   is 
  a 
  distinct 
  species, 
  — 
  the 
  one 
  ordinarily 
  occurring 
  in 
  Europe 
  

   being 
  the 
  N. 
  tremula^ 
  to 
  which 
  the 
  name 
  of 
  dictcea 
  has 
  been 
  

   improperly 
  applied. 
  Staudinger, 
  in 
  his 
  citation 
  of 
  N. 
  tremula 
  

   in 
  his 
  catalogue, 
  includes 
  as 
  a 
  synonym 
  " 
  Dictwa 
  (L. 
  S. 
  N. 
  

   xii, 
  826, 
  ex 
  Barbaria, 
  alia 
  species 
  esse 
  videtur)," 
  adding 
  the 
  

   references 
  to 
  the 
  following 
  authors 
  who 
  give 
  tremula 
  under 
  

   the 
  name 
  of 
  dict&a 
  : 
  "Esper, 
  58, 
  5 
  ; 
  84, 
  2; 
  Hiibner 
  Beitr., 
  22; 
  

   Ochsenh., 
  iii, 
  63 
  ; 
  Grodart, 
  iv, 
  19, 
  1; 
  Freyer, 
  579." 
  

  

  For 
  the 
  present 
  I 
  think 
  it 
  proper 
  to 
  retain 
  the 
  familiar 
  name 
  

   of 
  dictcza 
  for 
  the 
  species, 
  as 
  the 
  necessity 
  for 
  the 
  proposed 
  

   change 
  does 
  not 
  appear 
  to 
  be 
  clearly 
  shown.
