  tions 
  it 
  will 
  even 
  hibernate 
  in 
  different 
  states; 
  and 
  that, 
  finally, 
  the 
  great 
  bulk 
  of 
  

   them 
  hibernate 
  in 
  the 
  pupa 
  and 
  moth 
  states, 
  the 
  proportion 
  of 
  the 
  former 
  increasing 
  

   northward. 
  

  

  With 
  our 
  present 
  light 
  upon 
  this 
  subject, 
  and 
  especially 
  with 
  the 
  

   experience 
  of 
  the 
  past 
  two 
  years, 
  we 
  can 
  revise 
  this 
  opinion, 
  for 
  it 
  now 
  

   appears 
  that, 
  as 
  in 
  the 
  case 
  of 
  other 
  species 
  of 
  the 
  genus 
  Leucania, 
  and 
  

   of 
  so 
  many 
  of 
  our 
  ordinary 
  cut- 
  worms, 
  by 
  far 
  the 
  more 
  common 
  mode 
  

   of 
  hibernating 
  is 
  in 
  the 
  larva 
  state. 
  That 
  the 
  insect 
  does 
  hibernate 
  in 
  

   the 
  larva 
  state 
  is 
  fully 
  established 
  by 
  the 
  facts 
  already 
  given 
  and 
  by 
  the 
  

   following 
  summary; 
  

  

  First: 
  — 
  The 
  experience 
  noted 
  by 
  Professor 
  Oomstock 
  in 
  the 
  annual 
  

   report 
  of 
  this 
  Department 
  for 
  1879, 
  p. 
  188, 
  viz, 
  the 
  receipt 
  of 
  worms 
  from 
  

   Tennessee 
  and 
  South 
  Carolina 
  during 
  the 
  months 
  of 
  December, 
  Jan- 
  

   uary 
  and 
  February. 
  

  

  Second: 
  — 
  The 
  finding 
  of 
  young 
  worms 
  upon 
  the 
  Department 
  grounds 
  

   at 
  Washington 
  during 
  the 
  months 
  of 
  December, 
  1881, 
  and 
  January, 
  

   1882 
  — 
  already 
  referred 
  to 
  above. 
  

  

  Third 
  : 
  — 
  The 
  receipt 
  of 
  the 
  worms 
  at 
  this 
  Department 
  in 
  January, 
  1882, 
  

   from 
  Clay 
  County, 
  Alabamaj 
  the 
  first 
  week 
  in 
  March, 
  1882, 
  from 
  Lafay- 
  

   ette 
  County, 
  Mississippi, 
  Chatham 
  County, 
  Georgia, 
  and 
  Eichland 
  

   County, 
  South 
  Carolina 
  j 
  and 
  the 
  middle 
  of 
  March 
  from 
  Washington- 
  

   County, 
  Missouri. 
  

  

  Fourth: 
  — 
  The 
  finding 
  of 
  a 
  partly-grown 
  Army 
  Worm 
  in 
  the 
  stomach 
  

   of 
  a 
  blue-bird 
  at 
  ]S"ormal, 
  Ills., 
  March 
  9, 
  1880, 
  by 
  Professor 
  S. 
  A. 
  Forbes, 
  

   as 
  detailed 
  in 
  the 
  American 
  Entomologist^ 
  vol. 
  Ill 
  (1880), 
  p. 
  204. 
  

  

  Fifth: 
  — 
  The 
  observations 
  of 
  Mr. 
  Coquillett, 
  already 
  mentioned, 
  — 
  the 
  

   finding 
  of 
  six 
  partly-grown 
  Army 
  Worms 
  after 
  November 
  1, 
  under 
  or 
  

   in 
  shocks 
  of 
  corn 
  in 
  McHenry 
  County, 
  Illinois. 
  

  

  Instances 
  might 
  be 
  multiplied, 
  but 
  our 
  point 
  is 
  sufficiently 
  estab- 
  

   lished. 
  The 
  only 
  argument 
  of 
  any 
  weight 
  heretofore 
  brought 
  to 
  bear 
  

   upon 
  pupal 
  hibernation, 
  namely, 
  the 
  finding 
  of 
  fresh 
  moths 
  in 
  the 
  spring, 
  

   has 
  equal 
  weight 
  in 
  favor 
  of 
  larval 
  hibernation. 
  In 
  fact, 
  the 
  instance 
  

   cited 
  from 
  Mr. 
  Meske, 
  of 
  the 
  finding 
  of 
  the 
  chrysalis 
  and 
  the 
  breeding 
  

   of 
  the 
  moth 
  at 
  Albany, 
  l!^. 
  Y., 
  about 
  the 
  middle 
  of 
  May, 
  really 
  confirms 
  

   this 
  view 
  of 
  larval 
  hibernation, 
  as 
  in 
  case 
  of 
  pupal 
  hibernation 
  the 
  moth 
  

   would 
  undoubtedly 
  have 
  been 
  disclosed 
  at 
  an 
  earlier 
  period. 
  

  

  The 
  evidence 
  in 
  favor 
  of 
  the 
  hibernation 
  of 
  the 
  moth 
  is, 
  as 
  we 
  have 
  

   shown, 
  conclusive. 
  In 
  addition 
  to 
  the 
  i)roof 
  cited 
  we 
  may 
  mention 
  

   that 
  the 
  receipt 
  of 
  the 
  moth 
  from 
  the 
  Southern 
  States 
  during 
  the 
  win- 
  

   ter 
  months 
  has 
  been 
  of 
  very 
  frequent 
  occurrence 
  since 
  the 
  commence- 
  

   ment 
  of 
  the 
  Cotton 
  Insect 
  investigation, 
  observers 
  mistaking 
  Leucania 
  

   for 
  Aletia. 
  

  

  IJp 
  to 
  the 
  present 
  time 
  there 
  is 
  no 
  evidence 
  whatsoever 
  of 
  hiberna- 
  

   tion 
  in 
  either 
  the 
  egg 
  or 
  the 
  chrysalis 
  state, 
  though 
  the 
  evidence 
  may 
  

   yet 
  be 
  forthcoming.
