  simplex 
  are 
  the 
  Dalles 
  on 
  the 
  Columbia 
  River, 
  where 
  it 
  is 
  abundant 
  and 
  

   injurious. 
  I 
  have 
  received 
  it 
  from 
  the 
  Malheur 
  River 
  Indian 
  Reserva- 
  

   tion 
  in 
  Eastern 
  Oregon, 
  where 
  it 
  is 
  also 
  abundant. 
  It 
  also 
  inhabits 
  

   Montana. 
  Idaho 
  west 
  of 
  the 
  Rocky 
  Mountain 
  divide, 
  and, 
  without 
  doubt, 
  

   the 
  whole 
  of 
  Utah. 
  Mr. 
  J. 
  D. 
  Putnam 
  212 
  reports 
  it 
  as 
  common 
  in 
  the 
  

   valley 
  of 
  the 
  Wind 
  River, 
  on 
  the 
  plains 
  along 
  the 
  base 
  of 
  the 
  Wind 
  

   River 
  Mountains, 
  Wyoming, 
  in 
  July, 
  1873. 
  u 
  It 
  is 
  called 
  • 
  Mesch' 
  by 
  the 
  

   Shoshone 
  Indians, 
  who 
  are 
  said 
  to 
  sometimes 
  use 
  it 
  for 
  food." 
  Mr. 
  Put- 
  

   nam 
  also 
  states 
  that 
  it 
  was 
  " 
  very 
  common 
  in 
  Middle 
  Park, 
  Colorado, 
  

   in 
  September, 
  1872. 
  Scarcely 
  any 
  two 
  specimens 
  were 
  colored 
  alike. 
  

   The 
  male 
  was 
  frequently 
  seen 
  { 
  singing' 
  while 
  seated 
  in 
  the 
  top 
  of 
  a 
  

   wild 
  sage-bush, 
  the 
  female 
  being 
  found 
  on 
  the 
  ground 
  below." 
  

   Col. 
  E. 
  L. 
  Berthoud 
  writes 
  us 
  that 
  — 
  

  

  October 
  4-7, 
  1S7S, 
  the 
  large, 
  black 
  cricket 
  [without 
  doubt 
  A. 
  simplex], 
  so 
  common 
  in 
  

   Utah 
  and 
  Idaho, 
  were 
  very 
  abundant 
  at 
  Taghee 
  and 
  Henry's 
  Passes, 
  Henry's 
  Lake, 
  

   and 
  on 
  Henry's 
  Fork. 
  At 
  Taghee 
  Pass, 
  altitude 
  6,970 
  feet 
  above 
  the 
  sea, 
  they 
  seemed, 
  

   in 
  spite 
  of 
  cold 
  and 
  snow, 
  to 
  be 
  scarcely 
  hindered 
  by 
  a 
  temperature 
  of 
  7° 
  above 
  zero. 
  

  

  At 
  Portneuf 
  Cation 
  this 
  species 
  was 
  abundant 
  in 
  1878. 
  

  

  Of 
  its 
  southern 
  limits, 
  whether 
  it 
  occurs 
  in 
  Arizona, 
  Southern 
  Nevada, 
  

   Utah, 
  and 
  in 
  Xew 
  Mexico, 
  nothing 
  is 
  known. 
  Its 
  southern 
  range, 
  how- 
  

   ever, 
  is 
  probably 
  co-extensive 
  with 
  that 
  of 
  the 
  Rocky 
  Mountain 
  locust 
  

   (

  Anabrus 
  coloradus 
  thus 
  far 
  has 
  only 
  been 
  found 
  in 
  two 
  points, 
  Mani- 
  

   toba 
  on 
  the 
  north, 
  and 
  Southern 
  Colorado 
  and 
  adjacent 
  regions 
  on 
  the 
  

   south. 
  Mr. 
  Thomas 
  has 
  received 
  specimens 
  from 
  Manitoba, 
  and 
  has 
  

   collected 
  it 
  in 
  Colorado, 
  east 
  of 
  the 
  Rocky 
  Mountain 
  divide. 
  Mr. 
  Scud- 
  

   der 
  records 
  it 
  as 
  having 
  been 
  collected 
  by 
  Lieut. 
  W. 
  L. 
  Carpenter, 
  U. 
  S. 
  

   A., 
  in 
  Southern 
  Colorado. 
  June 
  11-20, 
  and 
  on 
  Taos 
  Peak, 
  Sangre 
  de 
  

   Cristo 
  Mountains. 
  Xew 
  Mexico, 
  at 
  a 
  height 
  of 
  13,000 
  feet 
  above 
  timber 
  

   line. 
  This 
  cricket 
  is 
  closely 
  allied 
  to 
  Anabrus 
  simplex, 
  and 
  appears 
  to 
  

   represent 
  that 
  species 
  in 
  the 
  plains 
  lying 
  east 
  of 
  the 
  Rocky 
  Mountain 
  

   divide. 
  It 
  appears 
  thus 
  far 
  to 
  have 
  a 
  greater 
  northern 
  and 
  southern 
  

   range 
  than 
  any 
  of 
  the 
  other 
  species.

  The 
  following 
  brief 
  synopsis 
  of 
  the 
  Decticides, 
  made 
  partly 
  from 
  that 
  

   of 
  Otto 
  Hermann 
  214 
  and 
  partly 
  from 
  the 
  arrangement 
  of 
  the 
  Locastidce 
  

   by 
  Ignacio 
  Bolivar, 
  215 
  will 
  show 
  the 
  relation 
  of 
  Anabrtis 
  to 
  the 
  other 
  

   genera 
  of 
  the 
  group, 
  and 
  the 
  chief 
  distinguishing 
  characters 
  : 
  

  

  A. 
  Prosternum 
  with 
  two 
  spines 
  between 
  the 
  base 
  of 
  the 
  anterior 
  legs. 
  This 
  division 
  

   contains 
  Ptcrolepis, 
  Bhacocleis, 
  Ihyreonotus, 
  and 
  several 
  other 
  

   genera. 
  As 
  Anabrus 
  Haldemanii 
  has 
  the 
  prosternum 
  spined 
  

   it 
  belongs 
  here, 
  probably 
  in 
  Pterolepis.
