  In 
  both 
  specimens 
  examined 
  by 
  me 
  the 
  coloration 
  is 
  practically 
  the 
  

   same, 
  except 
  that 
  the 
  halters 
  are 
  completely 
  inf 
  uscated 
  in 
  the 
  female. 
  

   The 
  scutellum 
  is 
  slightly, 
  though 
  distinctly, 
  notched 
  at 
  the 
  apex, 
  be- 
  

   tween 
  the 
  apical 
  pair 
  of 
  spines. 
  Veins 
  Mi 
  and 
  Mo 
  are 
  slightly 
  sepa- 
  

   rated 
  at 
  their 
  points 
  of 
  origin, 
  thus 
  differing 
  from 
  the 
  condition 
  

   described 
  and 
  illustrated 
  by 
  Lindner; 
  however, 
  this 
  character 
  is 
  of 
  

   minor 
  importance 
  and 
  is 
  variable 
  in 
  related 
  genera. 
  In 
  the 
  female 
  

   the 
  front, 
  at 
  its 
  narrowest, 
  is 
  about 
  one-sixth 
  the 
  head 
  width.
