  Although 
  this 
  handsome 
  insect 
  is 
  native 
  to 
  the 
  State 
  of 
  New 
  York, 
  the 
  

   moth 
  is 
  rarely 
  seen. 
  The 
  thickly-haired 
  caterpillars 
  of 
  this 
  and 
  allied 
  

   species 
  are 
  frequently 
  seen 
  in 
  the 
  autumn 
  crawling 
  rapidly, 
  as 
  though 
  in 
  

   haste 
  to 
  find 
  suitable 
  shelter 
  for 
  the 
  winter 
  before 
  the 
  setting 
  in 
  of 
  cold 
  

   weather. 
  This 
  particular 
  species 
  can 
  not 
  be 
  considered 
  injurious 
  in 
  this 
  

   latitude, 
  as 
  it 
  is 
  comparatively 
  rare, 
  but 
  in 
  some 
  of 
  the 
  southern 
  States 
  it 
  

   is 
  quite 
  abundant, 
  though 
  not 
  destructive. 
  

  

  The 
  Egg. 
  

  

  Eggs 
  of 
  a 
  moth 
  sent 
  me 
  October 
  6, 
  1884, 
  by 
  Mrs. 
  J. 
  P. 
  Ballard, 
  of 
  

   eastern 
  Pennsylvania, 
  and 
  received 
  by 
  her 
  i'rom 
  Orlando, 
  Florida, 
  proved 
  

   to 
  be 
  of 
  this 
  insect. 
  They 
  were 
  small, 
  0.025 
  ^^^^ 
  (4V) 
  i" 
  diameter, 
  

   round, 
  irregularly 
  punctate, 
  changing 
  before 
  hatching 
  from 
  whitish 
  to 
  

   reddish 
  and 
  finally 
  purplish 
  (Mr. 
  Dyar 
  gives 
  the 
  color 
  as 
  yellowish 
  

   pearly 
  gray). 
  The 
  duration 
  of 
  this 
  stage 
  was 
  about 
  five 
  days. 
  Less 
  than 
  

   one-half 
  of 
  the 
  shell 
  was 
  eaten 
  by 
  the 
  larva 
  upon 
  its 
  escape. 
  

  

  While 
  many 
  of 
  the 
  Arctians 
  are 
  known 
  to 
  be 
  quite 
  prolific, 
  this 
  one 
  is 
  

   markedly 
  so, 
  for 
  Mr. 
  Dyar 
  records 
  an 
  instance 
  in 
  which 
  he 
  obtained 
  

   2274 
  eggs 
  from 
  one 
  individual.
