  — 
  Two 
  females 
  collected 
  at 
  the 
  type 
  locality 
  by 
  S. 
  W. 
  Frost, 
  

   the 
  holotype 
  on 
  March 
  10, 
  the 
  paratype 
  on 
  March 
  22, 
  1937; 
  and 
  one 
  

   male 
  allotype 
  taken 
  by

  S. 
  CRYPTANURA 
  BICARINATA, 
  new 
  fpecies 
  

  

  Though 
  related 
  to 
  qu/idrhnaculata 
  in 
  its 
  possession 
  of 
  the 
  distinct 
  

   apical 
  carina 
  and 
  in 
  its 
  highly 
  polished 
  abdomen, 
  this 
  species 
  is 
  very 
  

   tlistiiict, 
  especially 
  in 
  the 
  minute 
  frontal 
  horns, 
  stouter 
  body, 
  and 
  

   ditferi'ut 
  arrangement 
  of 
  color. 
  It 
  seems 
  uidikely 
  that 
  this 
  can 
  be 
  

   championi 
  (Cameron), 
  also 
  from 
  Panama, 
  for 
  it 
  is 
  apparently 
  much 
  

   stouter 
  and 
  has 
  the 
  black 
  on 
  (he 
  inner 
  side 
  of 
  the 
  hind 
  fcnuir 
  rather 
  

   than 
  on 
  the 
  ui)per 
  side. 
  Moreover, 
  Cameron 
  does 
  not 
  mention 
  the 
  

   I)resenco 
  in 
  his 
  species 
  of 
  the 
  apical 
  carina 
  of 
  the 
  propodeum.
