   Sc 
  long, 
  Scx 
  ending

  of 
  R2+3; 
  cross-vein 
  r 
  far 
  out 
  toward 
  

   the 
  tip 
  of 
  Ri, 
  so 
  that 
  R^ 
  beyond 
  r 
  is 
  only 
  about 
  one-fifth 
  the

   on 
  Ri 
  from 
  Scg 
  to

  Rs 
  gently 
  arcuated 
  at 
  its 
  origin, 
  in 
  a 
  direct 
  line 
  

   with 
  R4+5, 
  consequently 
  no 
  basal 
  deflection 
  to 
  R4+5 
  is 
  present; 
  R2+3 
  

   short, 
  a 
  little 
  longer 
  than 
  the 
  basal 
  deflection 
  of 
  Cuj; 
  Cui-hMg 
  shorter 
  

   than 
  M3 
  alone; 
  basal 
  deflection 
  of

  If 
  the 
  specimen 
  figured 
  by 
  Wiedemann 
  ^ 
  was 
  really 
  a 
  specimen 
  of 
  

   his/wsca, 
  then 
  this 
  species 
  is 
  undoubtedly 
  closely 
  allied 
  to 
  fusca. 
  It 
  

   is 
  readily 
  distinguished 
  by 
  its

  brown 
  fore
