  anterior 
  lateral

   and 
  separated 
  from 
  posterior 
  lobe 
  by 
  a 
  deep 
  constriction, 
  posterior 
  

   lobe 
  gradually 
  widened 
  from 
  anterior 
  to 
  posterior 
  margin, 
  about 
  

   1.5 
  times 
  as

   elevated

  very 
  close

  This 
  species, 
  in 
  common 
  with 
  most 
  of 
  those 
  treated 
  in 
  this 
  paper, 
  

   has 
  the 
  fore 
  wing 
  concave 
  behind 
  the 
  apex 
  (fig. 
  23), 
  the 
  degree 
  

   of 
  concavity 
  varying 
  with 
  the 
  species, 
  the 
  least 
  occurring 
  in 
  

   pallidipennis.
