  which 
  seem 
  to 
  be 
  iilentical 
  with 
  those 
  of 
  T. 
  omlis 
  Pierce. 
  The 
  three 
  

   were 
  sent 
  to 
  Gilbert 
  Arrow, 
  of 
  the 
  British 
  Museum, 
  for 
  comparison 
  

   with 
  the 
  type, 
  with 
  the 
  su<rp:estion 
  that 
  T. 
  glohipennis 
  might 
  prove 
  

   to 
  be 
  iiientical 
  with 
  T. 
  ovalis. 
  The 
  fohowing 
  note

  Sir 
  Guy 
  Marshall 
  has 
  examined 
  the 
  specimens 
  of 
  Tosastes 
  and 
  compared 
  them 
  

   with 
  the 
  unique 
  type 
  of 
  T. 
  globipennis. 
  lie 
  finds 
  slight 
  difTcrcnces, 
  the 
  value 
  

   of 
  which 
  it 
  is 
  not 
  possible 
  to 
  decide 
  without 
  seeing 
  a 
  larger 
  number 
  of 
  specimens, 
  

   but 
  which 
  appear 
  to 
  him 
  to 
  make 
  it 
  undesirnl)le 
  for 
  the 
  present 
  to 
  sink 
  either 
  

   name. 
  

  

  No 
  comparison 
  of 
  genitalia 
  was 
  made. 
  

  

  Tiie 
  two 
  forms 
  appear 
  to 
  be 
  closely 
  related, 
  and 
  may 
  eventually 
  be 
  

   found 
  to 
  intergrade.
