  This 
  may 
  eventually 
  be 
  taken 
  as 
  the 
  type 
  of 
  a 
  new 
  genus 
  or 
  sub- 
  

   genus. 
  Ducke, 
  in 
  his 
  excellent 
  account 
  of 
  the 
  Neotropical 
  genera 
  of 
  

   bees 
  (1912), 
  recognizes 
  a 
  genus 
  Tetralonia 
  Spinola, 
  in 
  which 
  he 
  includes 
  

   Melissodes, 
  Thygater, 
  Peponapis, 
  Anthedon, 
  Xenoglossa, 
  and 
  several 
  

   other 
  groups 
  which 
  have 
  been 
  regarded 
  as 
  genera. 
  Michener, 
  in 
  

   1944, 
  has 
  a 
  tribe 
  Eucerini, 
  including 
  the 
  genera 
  (found 
  in 
  the 
  United 
  

   States) 
  Tetralonia, 
  Xenoglossa, 
  Peponapis, 
  Cemolobus, 
  Melissodes, 
  

   Xenoglossodes, 
  Anthedonia 
  (Anthedon 
  preoccupied), 
  Florilegus, 
  and 
  

   Martinapis. 
  It 
  will 
  be 
  seen 
  that 
  most 
  of 
  these 
  segregate 
  genera 
  

   contain 
  species 
  which 
  visit 
  particular 
  flowers. 
  How 
  far 
  to 
  go 
  in 
  the 
  

   subdivision 
  of 
  such 
  genera 
  is 
  a 
  matter 
  of 
  uncertainty. 
  Many 
  bees 
  

   that 
  Michener 
  regards 
  as 
  of 
  subgeneric 
  ranli 
  could 
  be 
  treated 
  as 
  

   genera. 
  

  

  It 
  now 
  appears 
  that 
  in 
  Central 
  America 
  there 
  is 
  a 
  series 
  of 
  segregate 
  

   forms, 
  which 
  probably 
  deserve 
  to 
  be 
  made 
  types 
  of 
  genera. 
  In 
  this 
  

   paper, 
  however, 
  I 
  have 
  followed 
  in 
  the 
  main 
  the 
  method 
  of 
  Ducke, 
  

   feeling 
  that 
  a 
  correct 
  generic 
  classification 
  must 
  be 
  made 
  later 
  when 
  

   the 
  sexes 
  are 
  known 
  and 
  have 
  been 
  matched 
  and 
  the 
  mouth 
  parts 
  

   and 
  genitalia 
  have 
  been 
  dissected.
