  Bruner 
  iei)orts 
  the 
  species 
  also 
  from 
  Xevada 
  and 
  Arizona. 
  

  

  Palmer 
  found 
  this 
  species 
  on 
  grassy 
  slopes, 
  beside 
  brooks. 
  

  

  The 
  form 
  enigma 
  appears 
  to 
  be 
  the 
  only 
  one 
  found 
  in 
  the 
  northern 
  

   part 
  of 
  the 
  range 
  of 
  the 
  species 
  north 
  of 
  central 
  Calilornia, 
  and 
  the 
  

   form 
  collar 
  is 
  is 
  rarely 
  met 
  with 
  anywhere. 
  

  

  The 
  different 
  forms 
  have 
  not 
  been 
  taken 
  in 
  coitu 
  with 
  each 
  other, 
  so 
  

   far 
  as 
  I 
  know. 
  The 
  form 
  jucumhis 
  besides 
  having 
  very 
  short 
  tegmiua, 
  

   is 
  noticeablj^ 
  smaller 
  than 
  the 
  others. 
  

  

  I 
  can 
  scarcely 
  think 
  the 
  form 
  collaris 
  to 
  be 
  the 
  insect 
  described 
  by 
  

   Thomas 
  as 
  Caleoptenus 
  [sic] 
  Jlavolineafus,^ 
  as 
  Bruner 
  has 
  supposed. 
  

   Thomas's 
  description 
  very 
  poorly 
  fits 
  it; 
  he 
  makes 
  no 
  mention 
  of 
  the 
  

   tumid 
  prozona, 
  and 
  he 
  states, 
  both 
  here 
  and 
  subsequently,^ 
  that 
  it 
  

   closely 
  resembles 
  Melanoplus 
  sjyretus, 
  and 
  that 
  the 
  posterior 
  margin 
  of 
  

   the 
  subgenital 
  plate 
  of 
  the 
  male 
  is 
  notched, 
  whereas 
  its 
  general 
  appear- 
  

   ance 
  is 
  very 
  different 
  indeed 
  from 
  M. 
  sprettis; 
  so 
  much 
  so 
  that 
  it 
  can 
  

   hardly 
  be 
  believed 
  that 
  anyone 
  would 
  select 
  it 
  for 
  comparison 
  ; 
  nor 
  has 
  

   the 
  apical 
  margin 
  of 
  the 
  subgenital 
  plate 
  the 
  faintest 
  sign 
  of 
  any 
  

   emargination. 
  Thomas's 
  specimen 
  was 
  derived 
  from 
  Crotch's 
  collection 
  

   in 
  the 
  Museum 
  of 
  Comparative 
  Zoology; 
  Crotch 
  collected 
  Oedaleonotns 
  

   enigma, 
  collaris 
  in 
  central, 
  not 
  southern, 
  California, 
  whereas 
  Thomas 
  

   gave 
  his 
  C. 
  Jiavolineatus 
  from 
  southern 
  California. 
  Thomas's 
  description 
  

   does 
  not 
  at 
  all 
  fit 
  any 
  species 
  from 
  southern 
  California 
  which 
  has 
  come 
  

   under 
  my 
  notice, 
  and 
  until 
  such 
  a 
  form 
  occurs 
  his 
  name 
  should 
  go 
  for 
  

   nothing 
  — 
  at 
  least 
  until 
  the 
  Acridian 
  fauna 
  of 
  that 
  region 
  is 
  fairly- 
  well 
  

   known.
