  The 
  published 
  accounts 
  add 
  very 
  little 
  to 
  the 
  above 
  range 
  of 
  distri- 
  

   bution, 
  except 
  that 
  it 
  is 
  reported 
  from 
  Quebec 
  (Provancher), 
  northern 
  

   California 
  (Packard), 
  Nevada 
  (Scudder), 
  and 
  south 
  as 
  far 
  as 
  middle 
  

   Florida 
  — 
  probably 
  by 
  error 
  (Packard). 
  

  

  It 
  is 
  probable, 
  therefore, 
  that 
  it 
  is 
  found 
  in 
  every 
  part 
  of 
  the 
  continu- 
  

   ous 
  district 
  of 
  the 
  United 
  States, 
  excepting 
  in 
  the 
  southernmost 
  Atlantic 
  

   States 
  and 
  most 
  of 
  California, 
  being 
  thus 
  limited 
  very 
  much 
  as 
  M.feni 
  >ir- 
  

   rubnim 
  ; 
  it 
  extends 
  also 
  into 
  central 
  Mexico, 
  and 
  north 
  of 
  our 
  boundary 
  

   is 
  found 
  from 
  Atlantic 
  to 
  Pacific 
  as 
  far 
  at 
  least 
  as 
  latitude 
  50° 
  (excei)t- 
  

   ing 
  Newfoundland), 
  and 
  on 
  the 
  Pacific 
  side 
  reaches 
  north 
  to 
  the 
  Yukon 
  

   River 
  and 
  probably 
  the 
  Lower 
  McKenzie. 
  

  

  Next 
  to 
  .1/. 
  spretus 
  this 
  is 
  our 
  most 
  destructive 
  locust, 
  and 
  east 
  of 
  

   the 
  ^Mississippi 
  probably 
  the 
  only 
  one 
  ever 
  doing 
  much 
  damage. 
  Its 
  

   injuries, 
  however, 
  are 
  not 
  for 
  a 
  moment 
  to 
  be 
  conii)ared 
  with 
  those 
  

   inflicted 
  by 
  M. 
  spretus, 
  for, 
  though 
  j^ossessing 
  good 
  powers 
  of 
  flight 
  

   and 
  on 
  rare 
  occasions 
  known 
  to 
  migrate 
  in 
  swarms, 
  its 
  injuries 
  can 
  only 
  

   be 
  classed 
  as 
  local, 
  and 
  they 
  are 
  never 
  so 
  serious 
  as 
  those 
  inflicted 
  by 
  

   M. 
  spreius 
  ; 
  nevertheless 
  they 
  are 
  by 
  no 
  means 
  slight, 
  and 
  immense 
  

   destruction 
  of 
  grain 
  is 
  to 
  be 
  laid 
  at 
  its 
  door. 
  Bruner, 
  who 
  has 
  studied 
  

   this 
  insect 
  over 
  a 
  wide 
  extent 
  of 
  country, 
  says 
  that 
  "while 
  it 
  occurs 
  

   over 
  . 
  . 
  . 
  an 
  extended 
  territory, 
  it 
  appears 
  to 
  be 
  . 
  . 
  . 
  partial 
  to 
  hill.\
