  the 
  recurrent 
  nervure 
  is 
  received 
  

   shortly 
  beyond 
  the 
  middle. 
  Petiole 
  shining, 
  impunctate, 
  

   the 
  base 
  depressed 
  ; 
  the 
  apex 
  of 
  the 
  depression 
  rounded 
  ; 
  

   its 
  sides 
  narrowly 
  keeled 
  ; 
  the 
  keels 
  obliquely 
  continued 
  to 
  

   shortly 
  beyond 
  the

  broadly 
  

   depressed

  at 
  the 
  base 
  ; 
  the 
  transverse 
  furrow 
  

   wide. 
  The 
  third, 
  fourth,

  fifth 
  segments 
  are 
  closely 
  

   and 
  rather 
  strongly

  : 
  there 
  are 
  no 
  

   marks 
  on

  there 
  are 
  two 
  large 
  marks 
  on 
  the 
  

   base 
  of 
  the

  on 
  the 
  base 
  of

  median 
  

   segment 
  distinctly 
  narrowed 
  from
