  The 
  only 
  form 
  to 
  

   ■which 
  I 
  was 
  inclined 
  to 
  refer 
  this 
  was 
  that 
  described 
  here 
  as 
  Melanoplus 
  bilituratns, 
  but 
  from 
  Mr. 
  Hen- 
  

   shaws 
  examination 
  of 
  the 
  types 
  (see 
  that 
  species, 
  p. 
  176) 
  it 
  can 
  not 
  be 
  that, 
  and 
  I 
  therefore 
  find 
  it 
  at 
  

   present 
  indeterminable. 
  I 
  have 
  specimens 
  from 
  Vancouver, 
  the 
  origin 
  of 
  "Walker's 
  species, 
  which 
  may 
  

   possibly 
  be 
  referred 
  to 
  scriptus, 
  since 
  they 
  differ 
  from 
  Melanoplus 
  bilituratus 
  in 
  the 
  points 
  specified 
  by 
  

   Mr. 
  Henshaw, 
  but 
  as 
  I 
  possess 
  only 
  females 
  I 
  do 
  not 
  feel 
  satisfied 
  of 
  tlieir 
  specific 
  validity.

  Walker's 
  types 
  (from 
  

   Oajaca, 
  Mexico) 
  were 
  examined 
  at 
  my 
  request 
  by 
  Mr. 
  Henshaw 
  to 
  see 
  whether 
  they 
  belong 
  in 
  th& 
  

   group 
  Melanopli 
  at 
  all, 
  and 
  he 
  states 
  that 
  they 
  do. 
  It 
  is 
  quite 
  impossible 
  by 
  Walker's 
  description 
  

   even 
  to 
  guess 
  to 
  what 
  genus 
  it 
  belongs, 
  much 
  less 
  to 
  determine 
  the 
  species 
  without 
  a 
  direct 
  compari- 
  

   son 
  with 
  the 
  types. 
  I 
  know 
  of 
  no 
  species 
  with 
  a 
  broad, 
  interrupted, 
  piceous 
  stripe 
  along 
  the 
  costa 
  of 
  

   the 
  tegmina.

  I 
  have 
  not 
  been 
  able 
  to 
  

   determine 
  this 
  species 
  among 
  my 
  material, 
  and 
  question 
  very 
  much 
  whether 
  it 
  belongs 
  in 
  the 
  Melan- 
  

   opli. 
  I 
  am 
  more 
  inclined 
  to 
  think 
  it 
  allied 
  to 
  Bactylotum.

  This 
  is 
  not 
  one 
  

   of 
  the 
  Melanopli, 
  but 
  belongs 
  to 
  Antandrtis 
  Stal. 
  

  

  Several 
  other 
  species 
  have 
  not 
  been 
  definitely 
  determined, 
  but 
  have 
  been 
  placed 
  in 
  the 
  synonymy 
  of 
  

   the 
  described 
  species 
  with 
  a 
  mark 
  of 
  doubt. 
  Such 
  are 
  Caloptenus 
  arcticus 
  Walker, 
  Locnsta 
  leucottoma 
  

   Kirby, 
  Pezotettix
