  Type!i. 
  — 
  Four 
  females, 
  the 
  holotype 
  and 
  three 
  paratj'pes 
  in 
  the 
  

   U. 
  S. 
  Natitmal 
  Museum 
  (No. 
  57058). 
  

  

  The 
  type 
  and 
  two 
  paratypes 
  were 
  taken 
  at 
  the 
  type 
  locality 
  by 
  H. 
  

   Lang. 
  The 
  third 
  paratype 
  is 
  from 
  Port-of-Spain, 
  Trinidad. 
  

  

  One 
  specimen 
  of 
  what 
  is 
  probably 
  the 
  male 
  of 
  this 
  species 
  was 
  taken 
  

   by 
  W. 
  M. 
  Mann 
  at 
  Cavinas, 
  Beni, 
  Bolivia, 
  during 
  the 
  Mulford 
  Bio- 
  

   lr)gical 
  Exploration 
  of 
  1921-22. 
  It 
  has 
  the 
  mesopleuron 
  and 
  sternum 
  

   almost 
  entirely 
  yellowish

  new 
  species 
  

  

  Apparently 
  closely' 
  allied 
  to 
  cctypa 
  (Cresson), 
  from 
  the 
  description 
  

   of 
  which 
  it 
  differs 
  in 
  its 
  possession 
  of 
  yellow 
  lateral 
  lines 
  on 
  the 
  meso- 
  

   scutum. 
  Also 
  Ciesson 
  makes 
  no 
  mention 
  of 
  the 
  presence, 
  in 
  his 
  

   species, 
  of 
  the 
  apical 
  carina 
  of 
  the 
  propodeum.
