  It 
  will 
  probably 
  be 
  impossible 
  ever 
  to 
  determine 
  definitely 
  Kirby's 
  

   Locusta 
  leueostoma, 
  as 
  the 
  description 
  is 
  altogether 
  inadequate 
  and 
  the 
  

   British 
  Museum 
  does 
  not 
  contain 
  the 
  type; 
  at 
  least 
  I 
  could 
  not 
  find 
  it 
  

   by 
  special 
  search 
  for 
  it 
  in 
  18G5, 
  and 
  it 
  is 
  not 
  mentioned 
  in 
  Walker's 
  

   catalogues; 
  Walker, 
  following 
  my 
  earlier 
  but 
  probably 
  wrong 
  determi- 
  

   nation, 
  idaced 
  it 
  as 
  a 
  synonym 
  of 
  ill. 
  bivittdttis, 
  but 
  none 
  of 
  his 
  speci-. 
  

   mens 
  included 
  Kirby's. 
  

  

  Mr. 
  Samuel 
  Henshaw, 
  during 
  a 
  recent 
  visit 
  to 
  the 
  British 
  Museum, 
  

   examined 
  the 
  types 
  of 
  Walker's 
  Galoptenus 
  extremns 
  and 
  found 
  them 
  to 
  

   agree 
  with 
  specimens 
  of 
  the 
  present 
  species 
  coming 
  from 
  Kennicott's 
  

   collection 
  on 
  the 
  upper 
  Mackenzie, 
  which 
  he 
  took 
  with 
  him; 
  they 
  

   differed 
  "only 
  in 
  having 
  slightly 
  shorter 
  wings^" 
  in 
  which 
  respect 
  

   W^alker's 
  specimens 
  agree 
  with 
  others 
  of 
  Kennicott's 
  collection 
  belonging 
  

   to 
  this 
  species.
