  These 
  two 
  species 
  belong 
  to 
  the 
  group 
  Sericei 
  of 
  Vachal. 
  The 
  

   description 
  of 
  A. 
  chryseis 
  Smith, 
  from 
  Guatemala, 
  nearly 
  applies 
  to 
  

   this 
  insect, 
  but 
  A. 
  chryseis 
  has 
  only 
  the 
  apex 
  of 
  the 
  clypeus 
  black, 
  

   the 
  base 
  of 
  the 
  metathorax 
  has 
  "longitudinal 
  striae 
  enclosed 
  by 
  a 
  

   sharp 
  elevated 
  ridge," 
  and 
  the 
  nervures 
  are 
  dark 
  ferruginous. 
  

  

  Schwarz 
  refers 
  bees 
  of 
  the 
  type 
  of 
  A. 
  vesta 
  and 
  A. 
  auriventris, 
  super- 
  

   ficially 
  resembling 
  those 
  now 
  described, 
  to 
  the 
  subgenus 
  Paraugo- 
  

   chloropsis 
  of 
  Schrottky, 
  but 
  these 
  are 
  vibrissate 
  species, 
  now 
  to 
  be 
  

   referred 
  to 
  Augochloropsis.

  If 
  we 
  define 
  Caenohalictus 
  as 
  "Augochlora 
  of 
  the 
  Sericei 
  group, 
  with 
  

   hair 
  on 
  the 
  eyes" 
  (Cockerell, 
  Ann. 
  Mag. 
  Nat. 
  Hist., 
  September 
  1912, 
  

   p. 
  318) 
  this 
  species 
  must 
  go 
  in 
  this 
  genus, 
  though 
  it 
  is 
  distinguished 
  

   by 
  the 
  very 
  strongly 
  crenulate 
  flagellum, 
  the 
  spines 
  on 
  hind 
  legs, 
  and
