  was 
  already 
  a 
  described 
  and 
  properly 
  named 
  species.* 
  The 
  

   type 
  must 
  be 
  selected 
  from 
  among 
  these 
  three. 
  The 
  

   selections 
  of 
  a 
  type 
  for 
  Crabro 
  by 
  Lamarck 
  (1801), 
  Latreille 
  

   (1810), 
  Curtis 
  (1837), 
  and 
  Westwood 
  (1840) 
  refer 
  to 
  Crabro 
  

   ¥., 
  1775, 
  not 
  to 
  Crabro 
  GeofEroy, 
  and 
  designate 
  a 
  species 
  

   not 
  included 
  by 
  Geoff 
  roy. 
  No 
  type 
  seems 
  to 
  have 
  been 
  

   specified 
  for 
  Crabro 
  GeofEroy; 
  and 
  one 
  is 
  therefore 
  here 
  

   chosen. 
  All 
  three 
  of 
  the 
  original 
  species 
  are 
  congeneric. 
  

  

  The 
  circumstance 
  is 
  a 
  most 
  unfortunate 
  one 
  in 
  that 
  it 
  

   requires 
  the 
  substitution 
  of 
  the 
  name 
  Crabro 
  for 
  the 
  well- 
  

   known 
  Cimbex, 
  both 
  names 
  involving 
  the 
  famihes 
  with 
  

   which 
  they 
  are 
  associated. 
  But 
  there 
  seems 
  to 
  be 
  no 
  

   recourse, 
  as 
  Crabro 
  F., 
  which 
  has 
  been 
  accepted 
  by 
  all 
  

   modern 
  writers, 
  is 
  an 
  absolute 
  homonym 
  of 
  Crabro 
  GeofEroy. 
  

  

  I 
  had 
  intended 
  to 
  make 
  lutea 
  L. 
  type, 
  but 
  the 
  Rev. 
  

   Mr. 
  Morice 
  suggests 
  to 
  me 
  that 
  it 
  would 
  be 
  better 
  to 
  select 
  

   humeralis, 
  since 
  that 
  species 
  is 
  known 
  for 
  certain, 
  whereas 
  

   it 
  is 
  doubtful, 
  according 
  to 
  him, 
  that 
  it 
  can 
  ever 
  be 
  settled 
  

   whether 
  lutea 
  L. 
  was 
  the 
  species 
  now 
  commonly 
  called 
  

   lutea 
  or 
  merely 
  the 
  yellow 
  bodied 
  form 
  ($) 
  of 
  what 
  we 
  

   know 
  as 
  femorata. 
  The 
  suggestion 
  is 
  a 
  happy 
  one 
  and 
  I 
  

   am 
  glad 
  to 
  accept 
  it.
