  Abdomen: 
  tergimi 
  dull 
  yellow, 
  tip 
  of 
  each 
  segment 
  light 
  brown; 
  

   lateral 
  margin 
  of 
  the 
  sclerites 
  broadly 
  dark 
  brown. 
  (Terminal 
  seg- 
  

   ments 
  broken.) 
  Sternum 
  pale 
  whitish, 
  a 
  narrow 
  yellow 
  median 
  

   stripe, 
  which 
  sub-apically 
  broadens 
  out 
  over 
  the

  sclerite. 
  

  

  Wings 
  : 
  subhyaline 
  with 
  a 
  faint 
  yellow 
  tinge 
  ; 
  brown 
  clouds 
  at 
  end 
  

   of 
  Rj, 
  Rjj 
  around 
  cross 
  vein 
  r, 
  at 
  fork 
  of 
  Ro+s. 
  at 
  origin 
  of 
  R4+5, 
  along 
  

   remainder 
  of 
  the 
  cord, 
  along 
  cross 
  vein 
  m 
  and 
  the 
  deflection 
  of 
  Mg. 
  

   Venation: 
  Sc 
  long, 
  approximating 
  R^ 
  at 
  the 
  tip 
  as 
  in 
  the 
  genus; 
  

   r 
  nearer 
  to 
  tip 
  of 
  R^ 
  than 
  to 
  the 
  fork 
  of 
  R2+3; 
  Rs 
  long, 
  strongly 
  arcu- 
  

   ated 
  at 
  its 
  origin, 
  then 
  running 
  parallel 
  to 
  Rj; 
  R2+3 
  in 
  a 
  line 
  with 
  Rs 
  

   and 
  R,; 
  R2 
  strongly 
  curved 
  cephalad 
  at 
  its 
  tip; 
  R3 
  strongly 
  curved 
  

   caudad 
  at 
  its 
  tip, 
  so 
  that 
  cell 
  Rg 
  is 
  very 
  broad 
  on 
  its 
  distal 
  portion; 
  

   deflected 
  portion 
  of 
  R4+g 
  very 
  long, 
  so 
  that 
  cell 
  R5 
  is 
  much 
  nearer 
  the 
  

   base 
  of 
  the 
  wing 
  than
