  This 
  is 
  as 
  given 
  by 
  Morice 
  and 
  Durrant. 
  The 
  genus 
  

   must 
  date, 
  however, 
  from 
  1796.* 
  

  

  It 
  is 
  to 
  be 
  hoped 
  that 
  authors 
  will 
  agree 
  to 
  the 
  sugges- 
  

   tion 
  of 
  Morice 
  and 
  Durrant 
  that 
  the 
  form 
  " 
  Nysso 
  " 
  was 
  a 
  

   misprint, 
  and 
  continue 
  to 
  use 
  the 
  spelling 
  ''Nysson'' 
  as 
  

   Latreille 
  himself 
  subsequently 
  spelled 
  it.

  Morice 
  and 
  Durrant 
  seem 
  to 
  have 
  overlooked 
  the 
  fact 
  

   that 
  Latreille 
  (1802 
  : 
  336), 
  instead 
  of 
  describing 
  Palarus 
  

   without 
  exponent, 
  erected 
  it 
  to 
  receive 
  " 
  La 
  tiphie 
  flavipede 
  

   de 
  Fabricius," 
  the 
  characters 
  of 
  which 
  he 
  discusses 
  at 
  some 
  

   length, 
  promising 
  to 
  give 
  the 
  generic 
  characters 
  at 
  greater 
  

   length 
  at 
  a 
  later 
  date. 
  This 
  promise 
  he 
  redeems 
  in 
  the 
  

   13th 
  volume 
  (1805 
  : 
  296), 
  where 
  he 
  also 
  adds 
  three 
  other 
  

   species 
  to 
  the 
  genus, 
  and 
  states 
  that 
  Gonius 
  of 
  Jurine 
  (a 
  

   nomen 
  nudum) 
  is 
  identical. 
  

  

  I 
  cannot 
  see 
  the 
  reason 
  for 
  suppressing 
  flavipes 
  — 
  

   [Crabro 
  flavipes 
  Fabr., 
  1781] 
  in 
  favour 
  of 
  auriginosus 
  

   Eversmann, 
  1849. 
  The 
  species 
  flavipes 
  was 
  based 
  on 
  

   Crabro 
  flavipes 
  of 
  Fabricius, 
  1781, 
  and 
  is 
  different 
  from 
  

   Tiphia 
  flavipes 
  of 
  Fabricius, 
  1793. 
  When 
  the 
  latter 
  was 
  

   brought 
  into 
  the 
  genus 
  (by 
  Latreille 
  in 
  1811) 
  its 
  name 
  

   was 
  properly 
  changed 
  to 
  rufipes. 
  What 
  Panzer 
  meant 
  by 
  

   flavipes 
  has 
  nothing 
  to 
  do 
  with 
  the 
  question. 
  Latreille, 
  

   however, 
  specifically 
  cites 
  Philanthus 
  flavipes 
  of 
  Panzer 
  as 
  

   a 
  synonym 
  of 
  the 
  former, 
  and 
  the 
  species 
  figured 
  by 
  

   Coquebert 
  of 
  the 
  latter. 
  

  

  Tiphia 
  variegata 
  Fabr. 
  has 
  priority, 
  however, 
  over
