  NOTES 
  ON 
  OTHER

  AND 
  ON

  In 
  addition 
  to 
  the 
  several 
  species 
  of 
  locusts 
  already 
  noticed 
  in 
  this 
  

   report, 
  there 
  are 
  at 
  least 
  upwards 
  of 
  two 
  hundred 
  and 
  seventy 
  others 
  

   that 
  are 
  known 
  to 
  inhabit 
  the 
  various 
  portions 
  of 
  North 
  America 
  north 
  

   of 
  Mexico, 
  and 
  which 
  are 
  more 
  or 
  less 
  injurious 
  to 
  the 
  agriculturist 
  

   and 
  to 
  those 
  who 
  are 
  in 
  any 
  way 
  dependent 
  upon 
  the 
  products 
  of 
  the 
  

   soil 
  for 
  their 
  living. 
  True, 
  but 
  few 
  of 
  these 
  various 
  locusts 
  ever 
  become 
  

   so 
  excessively 
  numerous 
  as 
  do 
  those 
  concerning 
  the 
  history 
  and 
  habits 
  

   of 
  which 
  I 
  have 
  just 
  written; 
  neither 
  do 
  they 
  ever, 
  except 
  on 
  rare 
  occa- 
  

   sions 
  and 
  with 
  a 
  few 
  species, 
  become 
  imbued 
  with 
  a 
  desire 
  to 
  migrate. 
  

  

  In 
  their 
  distribution 
  these 
  insects 
  vary 
  much. 
  Some 
  of 
  them 
  enjoy 
  a 
  

   very 
  wide 
  range, 
  and 
  are 
  well 
  represented 
  both 
  in 
  climatic 
  varieties 
  and 
  

   numbers; 
  others 
  are 
  less 
  widely 
  scattered 
  and 
  are 
  few 
  in 
  numbers, 
  

   while 
  still 
  others 
  are 
  local 
  in 
  their 
  haunts 
  and 
  quite 
  few 
  in 
  individuals. 
  

   Others 
  again, 
  while 
  local, 
  are 
  well 
  represented 
  in 
  numbers 
  in 
  their 
  imme- 
  

   diate 
  localities. 
  So 
  diverse 
  are 
  the 
  habits 
  of 
  these 
  various 
  species 
  of 
  

   "grasshoppers^' 
  that 
  almost 
  every 
  nook 
  embraced 
  within 
  this 
  entire 
  

   tract 
  of 
  country, 
  where 
  insect 
  life 
  is 
  possible, 
  possesses 
  its 
  one 
  or 
  two 
  or 
  

   even 
  more 
  representatives 
  of 
  this 
  group 
  of 
  jumping 
  insects. 
  Even 
  the 
  

   cold 
  and 
  almost 
  frigid 
  mountain 
  summits, 
  as 
  well 
  as 
  the 
  parched 
  and 
  

   desolate 
  desert 
  regions 
  of 
  Arizona 
  and 
  New 
  Mexico, 
  furnish 
  suitable 
  

   haunts 
  for 
  a 
  few 
  hardy 
  species 
  that 
  are 
  so 
  constructed 
  as 
  to 
  be 
  able 
  to 
  

   withstand 
  these 
  extremes 
  of 
  climate. 
  However 
  numerous 
  these 
  insects 
  

   and 
  diverse 
  their 
  haunts, 
  it 
  is 
  nevertheless 
  an 
  undeniable 
  fact 
  that 
  the 
  

   greater 
  number 
  by 
  far 
  are 
  partial 
  to 
  a 
  country, 
  the 
  climate 
  of 
  which 
  is 
  

   moderately 
  temperate 
  and 
  where 
  the 
  humidity 
  is 
  not 
  excessive. 
  Ne- 
  

   braska 
  alone 
  possesses 
  at 
  least 
  140 
  of 
  them. 
  

  

  In 
  the 
  distribution 
  of 
  these 
  insects 
  we 
  have 
  noticed 
  that 
  the 
  following 
  

   rules 
  can 
  be 
  relied 
  on 
  to 
  a 
  great 
  extent: 
  (Edipoda 
  and 
  allies 
  are 
  more 
  

   partial 
  to 
  warm, 
  sunny 
  slopes 
  where 
  the 
  ground 
  is 
  partially 
  bare 
  and 
  

   where 
  they 
  have 
  a 
  chance 
  to 
  flit 
  about 
  in 
  the 
  warm, 
  open 
  air 
  and 
  sun 
  

   themselves. 
  Caloptenus 
  and 
  allies, 
  as 
  Pezotettix, 
  Brachystola, 
  &c., 
  are 
  

   more 
  partial 
  to 
  low 
  and 
  cooler 
  localities 
  where 
  they 
  can 
  rest 
  in 
  the 
  shade 
  

   and 
  hop 
  about 
  among 
  the 
  more 
  luxuriant 
  and 
  tender 
  vegetation. 
  Acri- 
  

   dium 
  is 
  a 
  lover 
  of 
  dense 
  shrubbery 
  and 
  other 
  luxuriant 
  growths 
  of 
  vege-
