  NOTES. 
  

  

  1. 
  Since 
  the 
  foregoing 
  was 
  written 
  I 
  have 
  seen 
  " 
  abstract 
  " 
  of 
  a 
  paper 
  

   on 
  Leucania 
  unipuncta, 
  read 
  by 
  Prof. 
  0. 
  Y. 
  Eiley 
  at 
  the 
  Boston 
  meeting 
  

   of 
  the 
  A. 
  A. 
  A. 
  S., 
  August, 
  1880. 
  He 
  says: 
  ^' 
  In 
  the 
  latitude 
  of 
  Saint 
  

   Louis 
  there 
  are 
  two, 
  sometimes 
  three, 
  generations 
  in 
  a 
  year, 
  and, 
  per- 
  

   haps, 
  even 
  four 
  ; 
  and 
  farther 
  south 
  a 
  succession 
  of 
  generations, 
  scarcely 
  

   interrupted 
  during 
  mild 
  winters. 
  Probably 
  in 
  'New 
  England 
  there 
  are 
  

   two 
  geueratioDS, 
  the 
  second 
  one 
  being 
  ' 
  usually 
  unnoticed,' 
  and 
  existing 
  

   through 
  the 
  autumn, 
  winter, 
  and 
  early 
  spring 
  months. 
  

  

  '^ 
  It 
  is 
  an 
  established 
  fact 
  that 
  the 
  species 
  hibernates 
  both 
  as 
  larva 
  

   and 
  as 
  moth, 
  M-ith 
  strong 
  circumstantial 
  evidence 
  that 
  it 
  also 
  hibernates, 
  

   particularly 
  northward, 
  as 
  a 
  chrysalis 
  ; 
  but 
  we 
  have 
  no 
  evidence 
  that 
  it 
  

   can 
  hibernate 
  in 
  the 
  egg. 
  

  

  " 
  Excessive 
  injury 
  may 
  result 
  from 
  natural 
  local 
  increase, 
  or 
  from 
  

   moths 
  flying 
  in 
  great 
  numbers 
  from 
  other 
  localities, 
  and 
  concentrating 
  

   in 
  particular 
  fields. 
  Dry 
  seasons 
  are 
  favorable 
  to 
  the 
  multiplication 
  of 
  

   the 
  insect."
