﻿GEOGRAPHICAL 
  DISTRIBUTION 
  OF 
  THE 
  ARMY 
  WORM.

  Of 
  late 
  years, 
  a 
  few 
  American 
  Lepidopterists, 
  following 
  Mr. 
  A. 
  R. 
  

   (xrote, 
  have 
  adopted 
  Htibner's 
  generic 
  name 
  of 
  HeliopMla 
  in 
  place 
  of 
  

   Leucania. 
  We 
  would 
  repeat 
  here 
  Mr. 
  Eiley's 
  reasons 
  for 
  rejecting 
  this 
  

   and 
  other 
  of 
  Htibner's 
  ''coitus" 
  names 
  for 
  modern 
  genera. 
  

  

  I 
  consider 
  tliat 
  the 
  reasons 
  so 
  long 
  urged 
  by 
  entomologists 
  against 
  the 
  adoption 
  

   of 
  the 
  classification 
  of 
  the 
  "Tentamen" 
  and 
  " 
  Verzeichniss," 
  and 
  particularly 
  those 
  

   given 
  by 
  Guen^e, 
  for 
  not 
  following 
  this 
  last 
  in 
  his 
  admirable 
  work 
  on 
  the 
  Noctuidse, 
  

   are 
  good 
  and 
  sound. 
  The 
  Hiibnerian 
  classification 
  is 
  essentially 
  unreal 
  and 
  the 
  

   generic 
  divisions 
  so 
  inadequately 
  defined 
  that 
  I 
  doubt 
  if 
  any 
  one 
  would 
  attempt 
  to 
  

   make 
  use 
  of 
  the 
  works 
  in 
  question, 
  were 
  it 
  not 
  for 
  the 
  references 
  to 
  the 
  admirably 
  

   illustrated 
  works 
  of 
  the 
  same 
  author. 
  The 
  introduction 
  of 
  his 
  generic 
  terms 
  into 
  

   American 
  Lepidopterology 
  has 
  so 
  upset 
  its 
  nomenclature, 
  without 
  in 
  the 
  least 
  ad- 
  

   vancing 
  our 
  knowledge, 
  and 
  the 
  grounds 
  for 
  this 
  introduction 
  are 
  so 
  questionable, 
  

   that 
  those 
  who 
  make 
  these 
  insects 
  a 
  specialty 
  are 
  apt 
  in 
  the 
  future 
  to 
  divide 
  into 
  two 
  

   factions 
  — 
  the 
  Hiibnerites 
  and 
  the 
  anti-Hiibnerites 
  ; 
  in 
  which 
  event 
  the 
  latter 
  will 
  

   certainly 
  have 
  strong 
  support 
  from 
  entomologists 
  in 
  general.

  GEOGRAPHICAL 
  DISTRIBUTION. 
  

  

  Leucania 
  unipuncta 
  is 
  a 
  very 
  widespread, 
  we 
  may 
  say 
  cosmopolitan, 
  

   species, 
  though 
  nowhere, 
  as 
  far 
  as 
  we 
  are 
  aware, 
  is 
  it 
  particularly 
  noted 
  

   as 
  an 
  injurious 
  insect 
  except 
  in 
  the 
  United 
  States. 
  On 
  this 
  continent 
  

   its 
  range 
  is 
  great. 
  Packard's 
  map 
  (Report 
  on 
  Rocky 
  Mountain 
  Locusts, 
  

   &c.) 
  gives 
  its 
  southern 
  limit 
  as 
  the 
  southernmost 
  point 
  of 
  Texas; 
  its 
  

   western 
  limit 
  at 
  102^ 
  west; 
  north 
  at 
  parallel 
  48° 
  in 
  Minnesota 
  and 
  at 
  

   Cape 
  Rozier 
  in 
  Quebec, 
  and 
  east 
  at 
  the 
  easternmost 
  point 
  of 
  Nova 
  Scotia. 
  

   We 
  have 
  no 
  data 
  as 
  to 
  a 
  wider 
  range 
  except 
  that 
  in 
  the 
  British 
  Museum 
  

   catalogue 
  of 
  lepidoptera 
  this 
  species 
  is 
  entered 
  as 
  from 
  "the 
  west 
  coast 
  

   of 
  North 
  America." 
  Without 
  much 
  doubt, 
  however, 
  it 
  will 
  be 
  found 
  

   farther 
  west 
  and 
  farther 
  north 
  than 
  the 
  limits 
  we 
  have 
  mentioned, 
  as 
  

   collections 
  from 
  out 
  of 
  the 
  way 
  spots 
  become 
  more 
  common. 
  The 
  re- 
  

   gions 
  most 
  ravaged, 
  as 
  taken 
  from 
  Packard's 
  map, 
  are 
  as 
  follows: 
  

   Eastern 
  Iowa, 
  Southern 
  and 
  Central 
  Wisconsin, 
  excluding 
  an 
  eastern 
  

   strip; 
  Northwestern, 
  Southern, 
  and 
  Central 
  Illinois; 
  Eastern 
  Kansas, 
  

   Eastern 
  Missouri, 
  Southwestern 
  and 
  Southeastern 
  Indiana, 
  Nortliern 
  

   Kentucky, 
  the 
  whole 
  of 
  Ohio, 
  Eastern 
  and 
  Western 
  Pennsylvania, 
  East- 
  

   ern 
  and 
  Southern 
  New 
  York, 
  Western 
  New 
  Jersey, 
  the 
  whole 
  of 
  New 
  

   England, 
  except 
  a 
  small 
  western 
  strip 
  of 
  Massachusetts 
  and 
  Connecti- 
  

   cut, 
  and 
  the 
  northwestern 
  half 
  of 
  Vermont. 
  

  

  The 
  species 
  has 
  not 
  been 
  found, 
  so 
  far 
  as 
  we 
  know, 
  in 
  the 
  West 
  In- 
  

   dies, 
  though 
  we 
  certainly 
  think 
  that 
  it 
  exists 
  there. 
  Both 
  Guenee 
  and 
  

   Walker 
  mention 
  it 
  from 
  various 
  parts 
  of 
  South 
  America 
  — 
  Venezuela, 
  

   United 
  States 
  of 
  Colombia, 
  and 
  Brazil. 
  In 
  Europe 
  it 
  has 
  been 
  recorded 
  

   from 
  the 
  Isle 
  of 
  Wight, 
  and 
  from 
  Lewes, 
  South 
  England. 
  Farther 
  east 
  

   the 
  moth 
  has 
  been 
  captured 
  in 
  the 
  Province 
  of 
  Nepaul, 
  North 
  India, 
  in 
  

   Java, 
  in 
  several 
  localities 
  in 
  Australia, 
  and, 
  to 
  end 
  our 
  list, 
  in 
  New 
  

   Zealand.
