  I 
  was 
  at 
  first 
  inclined 
  to 
  refer 
  this 
  to 
  C. 
  transversa 
  Perez, 
  but 
  it 
  is 
  

   larger, 
  and 
  the 
  female 
  labrum 
  is 
  entirely 
  white 
  (only 
  the 
  basal 
  half 
  in 
  

   transversa) 
  , 
  and 
  the 
  clypeal 
  marks 
  are 
  not 
  strictly 
  transverse, 
  but 
  a 
  

   little 
  oblique. 
  The 
  white 
  face 
  marks 
  separate 
  it 
  from 
  C. 
  confinis 
  

   Perez.

  In 
  Friese's 
  system 
  it 
  falls 
  nearest 
  to 
  C. 
  minuta 
  Moscary, 
  but 
  it 
  

   differs 
  in 
  several 
  respects. 
  It 
  is 
  really 
  nearest 
  to 
  C. 
  ruae 
  Cockerell, 
  

   from 
  which 
  it 
  differs 
  chiefly 
  in 
  the 
  entirely 
  pale 
  stigma, 
  lack 
  of 
  lateral 
  

   face 
  marks, 
  and 
  smaller 
  size.
