  Mo., 
  the 
  worms 
  abounded 
  this 
  year 
  in 
  parts 
  of 
  Boone 
  County, 
  Missouri, 
  

   as 
  stated 
  in 
  our 
  Eigiith 
  Missouri 
  Entomological 
  Eeport. 
  

  

  1855. 
  — 
  This 
  was 
  the 
  year 
  in 
  which 
  Mr. 
  John 
  Kirk 
  patrick 
  first 
  studied 
  

   the 
  Army 
  Worm. 
  He 
  reared 
  the 
  worms 
  to 
  the 
  perfect 
  state 
  and 
  de- 
  

   scribed 
  the 
  larva 
  and 
  the 
  moth. 
  Their 
  work 
  is 
  described 
  as 
  follows 
  : 
  

  

  Last 
  season 
  (1855), 
  in 
  consequence 
  of 
  the 
  heavy 
  rahis 
  in 
  the 
  early 
  part 
  of 
  June., 
  the 
  

   flats 
  of 
  the 
  Cuyahoga 
  (Northern 
  Oh 
  io) 
  were 
  flooded. 
  After 
  the 
  subsidence 
  of 
  the 
  water, 
  

   and 
  while 
  the 
  grass 
  was 
  yet 
  coated 
  with 
  the 
  muddy 
  deposit, 
  myriads 
  of 
  small 
  blackish 
  

   caterpillars 
  appeared 
  ; 
  almost 
  every 
  blade 
  had 
  its 
  inhabitant 
  ; 
  no 
  animal 
  could 
  feed 
  

   upon 
  it 
  without 
  at 
  every 
  bite 
  swallowing 
  several 
  ; 
  if 
  a 
  new 
  blade 
  sprung 
  up 
  it 
  was 
  

   immediately 
  devoured 
  ; 
  but, 
  what 
  was 
  more 
  remarkable, 
  the 
  insects 
  did 
  not 
  attempt 
  to 
  

   aremove 
  to 
  land 
  a 
  foot 
  or 
  two 
  higher, 
  but 
  that 
  had 
  not 
  been 
  covered 
  by 
  the 
  water, 
  

  

  1856. 
  — 
  Union 
  County, 
  Illinois. 
  

  

  1857. 
  — 
  In 
  1857 
  the 
  worms 
  again 
  appeared 
  in 
  Union 
  County, 
  Illinois, 
  

   and 
  also 
  in 
  Maryland. 
  A 
  writer 
  from 
  the 
  latter 
  State 
  gives 
  an 
  account 
  

   ■of 
  the 
  worms 
  in 
  the 
  ITew 
  Jersey 
  Farmer 
  of 
  that 
  year. 
  He 
  describes 
  

   for 
  the 
  first 
  time 
  two 
  of 
  the 
  Army 
  Worm's 
  x)arasites 
  — 
  the 
  one 
  a 
  Micro- 
  

   gaster 
  (probably 
  M. 
  militaris 
  Walsh), 
  and 
  the 
  other 
  a 
  Tachinid 
  (prob- 
  

   ably 
  Kirkpatrick's 
  Nemorcea 
  leiicanioi), 
  

  

  1858. 
  — 
  Illinois 
  (Fitch) 
  ; 
  northern 
  counties 
  of 
  Illinois 
  (Walsh). 
  

  

  1861. 
  — 
  This 
  is 
  by 
  far 
  the 
  most 
  celebrated 
  of 
  the 
  Army 
  Worm 
  years, 
  

   because, 
  in 
  the 
  first 
  place, 
  the 
  worms 
  appeared 
  in 
  destructive 
  numbers 
  

   over 
  an 
  immense 
  extent 
  of 
  country, 
  and, 
  in 
  the 
  second 
  place, 
  because 
  

   this 
  appearance 
  called 
  forth 
  the 
  elaborate 
  articles 
  of 
  Fitch, 
  Walsli, 
  

   Kirkpatrick, 
  Thomas, 
  Packard, 
  and 
  Shurtleff. 
  Indeed, 
  barring 
  Kirk- 
  

   patrick's 
  short 
  note 
  in 
  1855, 
  this 
  was 
  the 
  first 
  year 
  in 
  w^hich 
  the 
  Army 
  

   Worm 
  had 
  been 
  at 
  all 
  scientifically 
  studied. 
  Its 
  distribution 
  this 
  year 
  

   was 
  as 
  follows 
  : 
  

  

  It 
  was 
  flrst 
  noticed 
  in 
  numbers 
  sufficient 
  to 
  cause 
  alarm 
  in 
  Tennessee 
  and 
  Ken- 
  

   tucky 
  during 
  the 
  month 
  of 
  April; 
  and 
  toward 
  the 
  close 
  of 
  the 
  same 
  month 
  it 
  ap- 
  

   peared 
  in 
  the 
  southern 
  counties 
  of 
  Illinois. 
  By 
  the 
  end 
  of 
  June 
  it 
  had 
  visited 
  nearly 
  

   ^11 
  portions 
  of 
  the 
  latter 
  State, 
  proving 
  more 
  or 
  less 
  destructive 
  to 
  grass, 
  wheat, 
  oats, 
  

   rye, 
  sorghum, 
  and 
  corn. 
  

  

  Its 
  advent 
  in 
  Missouri 
  was 
  simultaneous 
  with 
  that 
  in 
  Illinois, 
  and, 
  judging 
  from 
  

   what 
  facts 
  I 
  have 
  accumulated, 
  it 
  occurred 
  very 
  generally 
  over 
  this 
  State, 
  though 
  

   recorded 
  only 
  in 
  Saint 
  Louis, 
  Jefi^erson, 
  Warren, 
  Boone, 
  Howard, 
  and 
  Pike 
  Counties. 
  

   .No 
  mention 
  is 
  made 
  of 
  its 
  occurrence, 
  at 
  this 
  time, 
  in 
  any 
  of 
  the 
  States 
  or 
  Territories 
  

   west 
  of 
  Missouri, 
  but 
  to 
  the 
  east 
  scarcely 
  a 
  single 
  State 
  escaped 
  its 
  ravages. 
  In 
  

   imany 
  portions 
  of 
  Ohio 
  it 
  entirely 
  destroyed 
  the 
  hay 
  and 
  grain 
  crops. 
  (Riley's

  Along 
  the 
  Ohio 
  Kiver, 
  in 
  the 
  southern 
  part 
  of 
  the 
  State, 
  and 
  even 
  as 
  

   far 
  north 
  as 
  Shelby 
  County, 
  the 
  damage 
  was 
  all 
  done 
  prior 
  to 
  the 
  mid- 
  

   dle 
  of 
  June, 
  while 
  in 
  the 
  northern 
  counties, 
  bordering 
  on 
  Lake 
  Erie, 
  

   the 
  worms 
  w^ere 
  not 
  observed 
  until 
  the 
  1st 
  of 
  August. 
  They 
  were 
  prev- 
  

   alent 
  in 
  Indiana, 
  the 
  northern 
  and 
  w^estern 
  portions 
  of 
  Pennsylvania, 
  

   the 
  southern 
  and 
  western 
  portions 
  of 
  New 
  York, 
  as 
  far 
  north 
  as 
  Seneca 
  

   County; 
  in 
  all 
  ISTew 
  Jersey, 
  and 
  throughout 
  ail 
  New 
  England, 
  along 
  

   the 
  sea 
  coast 
  as 
  far 
  as 
  the 
  Saint 
  Croix 
  Eiver, 
  in 
  Maine, 
  and 
  as 
  far 
  north 
  

   -as
