  hair, 
  especially 
  noticeable 
  at 
  sides, 
  and 
  there 
  are 
  no 
  golden 
  bands, 
  

   such 
  as 
  are 
  found 
  in 
  P. 
  mayarum 
  and 
  its 
  allies. 
  The 
  hair 
  at 
  the 
  sides 
  

   of 
  the 
  thorax 
  is 
  entirely 
  whitish, 
  not 
  partly 
  dark 
  as 
  in 
  P. 
  mezicana 
  

   Cresson. 
  The 
  ocelli 
  are 
  close 
  together 
  and 
  not 
  particularly 
  large.

  This 
  handsome 
  species 
  resembles 
  P. 
  buchwaldi 
  Friese 
  from 
  Costa 
  

   Kica, 
  but 
  that 
  is 
  regarded 
  by 
  Friese 
  as 
  a 
  variety 
  of 
  P. 
  ducalis 
  Smith 
  

   (eximia 
  Smith), 
  which 
  is 
  very 
  different 
  from 
  the 
  present 
  insect. 
  It 
  

   does, 
  however, 
  resemble 
  P. 
  ducalis 
  in 
  the 
  long 
  marginal 
  cell, 
  which 
  

   separates 
  it 
  from 
  P. 
  mexicana 
  Cresson. 
  P. 
  eximia 
  is 
  from 
  Mexico, 
  

   and 
  Schrottky 
  had 
  P. 
  ducalis 
  from 
  Argentina 
  and 
  considered 
  it 
  a 
  

   different 
  species, 
  contrary 
  to 
  the 
  opinion 
  of 
  Friese.
