  On 
  September 
  26th, 
  larvae 
  of 
  the 
  third 
  brood 
  were 
  reported 
  as 
  com- 
  

   mitting 
  serious 
  ravages 
  on 
  the 
  farm 
  of 
  Jacob 
  Harder, 
  Ghent, 
  N. 
  Y., 
  

   where 
  the 
  second 
  brood 
  had 
  been 
  destructive 
  in 
  July.* 
  A 
  number 
  of 
  

   the 
  larvae 
  were 
  sent 
  to 
  my 
  office, 
  of 
  which 
  the 
  last 
  buried 
  for 
  pupation, 
  

   about 
  October 
  12th. 
  Moths 
  from 
  these 
  began 
  to 
  emerge 
  the 
  27th, 
  and 
  

   continued 
  to 
  do 
  so 
  until 
  November 
  21st. 
  During 
  this 
  time, 
  77 
  moths 
  

   made 
  their 
  appearance, 
  coming 
  out 
  most 
  abundantly 
  from 
  November 
  

   2nd 
  to 
  the 
  loth. 
  The 
  appearance 
  of 
  the 
  adults 
  so 
  late 
  in 
  the 
  season, 
  

   renders 
  it 
  quite 
  probable 
  that 
  they 
  hibernate 
  in 
  the 
  imago 
  state 
  in 
  Al- 
  

   bany, 
  as 
  has 
  been 
  observed 
  at 
  Cambridge, 
  Mass., 
  although 
  a 
  portion 
  

   of 
  the 
  brood 
  may 
  also 
  winter 
  as 
  pupae. 
  According 
  to 
  Dr. 
  Howard, 
  the 
  

   insect 
  may 
  exceptionally 
  pass 
  the 
  winter 
  in 
  the 
  egg 
  in 
  some 
  of 
  the 
  

   Southern 
  States. 
  It 
  will 
  be 
  seen 
  that 
  these 
  observations 
  on 
  the 
  life- 
  

   history 
  of 
  this 
  insect 
  agree 
  quite 
  closely 
  with 
  those 
  of 
  Prof. 
  Weed, 
  at 
  

   Durham, 
  New 
  Hampshire 
  ; 
  and 
  other 
  observations 
  render 
  it 
  probable 
  that 
  

   there 
  are 
  ordinarily 
  three 
  broods 
  each 
  year 
  in 
  the 
  other 
  New 
  England 
  

   States, 
  with 
  the 
  exception 
  of 
  northern 
  Maine. 
  In 
  New 
  Jersey, 
  Dr. 
  

   Smith 
  reports 
  three 
  generations 
  as 
  the 
  normal 
  number 
  in 
  the 
  northern 
  

   portion 
  of 
  .the 
  State, 
  while 
  in 
  the 
  southern 
  part 
  a 
  fourth 
  is 
  by 
  no 
  means 
  

  

  unusual. 
  

  

  Summary 
  of 
  Life-history. 
  

  

  The 
  life-history 
  of 
  the 
  army-worm, 
  so 
  far 
  as 
  known 
  in 
  this 
  State 
  and 
  

   the 
  vicinity, 
  may 
  be 
  briefly 
  summarized 
  as 
  follows 
  : 
  Overwintered 
  moths 
  or 
  

   recently 
  emerged 
  ones, 
  which 
  may 
  have 
  hibernated 
  as 
  larvae, 
  or 
  possibly 
  

   pupae, 
  deposit 
  eggs 
  early 
  in 
  the 
  spring, 
  and 
  from 
  them 
  the 
  first 
  brood 
  of 
  

   larvae 
  develop. 
  From 
  their 
  comparatively 
  small 
  number, 
  they 
  rarely 
  

   prove 
  very 
  destructive 
  and 
  are 
  consequently 
  unnoticed. 
  They 
  mature, 
  

   pupate, 
  and 
  the 
  adults 
  emerge 
  and 
  lay 
  the 
  eggs 
  from 
  which 
  is 
  produced 
  

   the 
  second 
  brood. 
  These 
  in 
  turn 
  become 
  nearly 
  full-grown 
  early 
  in 
  July, 
  

   and 
  we 
  have 
  the 
  brood 
  usually 
  destructive, 
  and 
  the 
  one 
  which 
  com.mitted 
  

   such 
  widespread 
  ravages 
  in 
  the 
  State 
  the 
  present 
  year. 
  Pupation 
  occurs 
  

   in 
  July 
  and 
  the 
  moths 
  emerge 
  early 
  in 
  August. 
  They 
  deposit 
  eggs 
  the 
  

   latter 
  part 
  of 
  the 
  month, 
  and 
  early 
  in 
  September 
  the 
  third 
  brood 
  makes 
  

   its 
  appearance 
  and 
  by 
  the 
  latter 
  part 
  of 
  the 
  month 
  they 
  are 
  full-grown. 
  

   This 
  is 
  the 
  brood 
  which 
  was 
  quite 
  destructive 
  the 
  present 
  season, 
  at 
  

   Ghent, 
  N. 
  Y., 
  pupating 
  the 
  last 
  of 
  September, 
  or 
  early 
  in 
  October, 
  — 
  the 
  

   moths 
  emerging 
  the 
  last 
  of 
  October 
  and 
  into 
  November, 
  and 
  most 
  prob- 
  

   ably 
  passing 
  the 
  winter 
  in 
  the 
  imago 
  state. 
  

  

  ♦They 
  were 
  also 
  reported 
  as 
  destructive 
  on 
  several 
  farms 
  in 
  Berlin, 
  Bolton, 
  Northboro, 
  and 
  

   other 
  places 
  in 
  Worcester 
  county, 
  Mass., 
  during 
  the 
  last 
  of 
  the 
  month.
