  From 
  3 
  <$'s 
  and 
  6 
  ?'s, 
  in 
  the 
  Collections 
  of 
  Messrs. 
  von

  Strecker 
  and

  The 
  seven 
  black 
  spots 
  on 
  the 
  white 
  ground 
  intermediate 
  to 
  

   the 
  bands, 
  arranged 
  in 
  an 
  ellipse 
  as 
  above 
  described, 
  readily 
  

   distinguish 
  this 
  species 
  from 
  arty 
  other 
  of 
  the 
  genus. 
  

  

  It 
  is 
  closely 
  allied 
  to 
  the 
  O. 
  bicuspis 
  of 
  Europe. 
  Mr. 
  A. 
  Gf. 
  

   Butler, 
  of 
  the 
  British 
  Museum, 
  to 
  whom 
  I 
  communicated 
  an 
  

   excellent 
  photograph 
  of 
  it, 
  writes 
  : 
  "it 
  precisely 
  agrees 
  with 
  

   some 
  of 
  our 
  European 
  examples 
  of 
  blcuspis." 
  Dr. 
  Speyer 
  

   who 
  has 
  received 
  an 
  example 
  from 
  Mr. 
  von 
  Meske, 
  remarks 
  

   of 
  it 
  : 
  "it 
  is 
  very 
  near 
  to 
  bicuspis." 
  

  

  Although 
  quite 
  dissimilar 
  in 
  color 
  from 
  G. 
  cinerea 
  Walker, 
  

   yet 
  it 
  is 
  closely 
  related 
  to 
  that 
  species 
  in 
  the 
  form 
  of 
  the 
  bands 
  

   (often 
  imperfectly 
  denned 
  in 
  cinerea) 
  and 
  in 
  the 
  arrangement 
  

   of 
  the 
  intermediate 
  nervular 
  spots. 
  

  

  The 
  moth 
  has 
  been 
  reared 
  from 
  larvae 
  found 
  by 
  Mr. 
  F. 
  Tep- 
  

   per 
  of 
  Flatbush, 
  L. 
  I., 
  feeding 
  on 
  wild 
  cherry, 
  when 
  near 
  their 
  

   maturity. 
  I 
  am 
  indebted 
  to 
  him 
  for 
  the 
  following 
  note 
  in 
  re- 
  

   gard 
  to 
  them. 
  "They 
  are 
  of 
  the 
  same 
  shape 
  as 
  borealis 
  {occi- 
  

   dentalism 
  but 
  differently 
  colored. 
  Instead 
  of 
  the 
  green 
  of 
  that 
  

   species, 
  the 
  color 
  is 
  greenish-yellow, 
  the 
  dorsal 
  patch 
  is 
  rather 
  

   smaller 
  and 
  of 
  a 
  brighter 
  shade, 
  and 
  the 
  minute 
  spots 
  on 
  the 
  

   sides 
  are 
  more 
  delicate 
  and 
  brighter. 
  The 
  examples 
  met 
  with 
  

   have 
  been 
  larger 
  than 
  borealis 
  and 
  somewhat 
  heavier 
  in 
  ap- 
  

   pearance. 
  Three 
  mature 
  larvae 
  were 
  taken 
  by 
  me 
  between 
  the 
  

   10th 
  and 
  15th 
  of 
  July, 
  1875 
  ; 
  one 
  was 
  ichneumonized 
  ; 
  the 
  

   other 
  two 
  spun 
  up 
  in 
  the 
  same 
  manner 
  as 
  borealis, 
  within 
  a 
  

   few 
  days 
  after 
  their 
  capture, 
  and 
  the 
  moths 
  emerged 
  in 
  from 
  

   two 
  to 
  three 
  weeks." 
  

  

  In 
  Smith 
  and 
  Abbot' 
  s 
  Insects 
  of 
  Georgia 
  it 
  is 
  said 
  of 
  it 
  : 
  

   " 
  The 
  caterpillar 
  was 
  taken 
  the 
  latter 
  end 
  of 
  July, 
  feeding 
  on 
  

   that 
  kind 
  of 
  poplar 
  vulgarly 
  called 
  the 
  cotton-tree. 
  When 
  dis- 
  

   turbed, 
  it 
  shoots 
  out 
  of 
  the 
  ends 
  of 
  its 
  forked 
  tail 
  two 
  soft 
  

   orange-colored 
  threads. 
  Early 
  in 
  August 
  it 
  shed 
  its 
  skin, 
  and 
  

   on 
  the 
  10th 
  of 
  that 
  month 
  it 
  inclosed 
  itself 
  in 
  a 
  case 
  made 
  of 
  

   chips 
  of 
  wood 
  and 
  affixed 
  to 
  a 
  branch. 
  The 
  moth 
  came 
  out 
  

   April 
  24th. 
  It 
  likewise 
  feeds 
  on 
  the 
  wild 
  cherry 
  and 
  willow, 
  

   and 
  is 
  found 
  also 
  in 
  Virginia, 
  but 
  it 
  is 
  a 
  very 
  rare 
  species.'.'
