  Navy 
  (Type,

  A 
  rather 
  pronounced 
  variation, 
  not 
  matched 
  by 
  any 
  other 
  

   specimens 
  seen 
  by 
  me 
  and 
  unfortunately 
  not 
  well 
  labelled. 
  The 
  

   name 
  is 
  not 
  my 
  own 
  selection, 
  but 
  was 
  applied 
  to 
  the 
  sheet 
  by 
  

   someone 
  whose 
  handwriting 
  I 
  was 
  unable 
  to 
  get 
  identified. 
  It 
  

   evidently 
  was 
  suggested 
  by 
  the 
  conspicuous 
  stifi* 
  hairs.
