  Abdomen 
  rather 
  broad 
  and 
  short, 
  shining 
  black 
  ; 
  the 
  tergites 
  faintly 
  reticulate 
  

   medianly, 
  but 
  distinctly 
  so 
  at 
  the 
  sides 
  and 
  on 
  the 
  portion 
  underlapping 
  the 
  sternites 
  ; 
  

   petiole 
  short 
  ; 
  tergites 
  2 
  and 
  5 
  subequal. 
  Post-median 
  row 
  of 
  bristles 
  interrupted 
  

   in 
  the 
  middle 
  on 
  tergites 
  2 
  and 
  3. 
  Spiracle 
  small 
  and 
  circular. 
  The 
  stylet 
  on 
  tergite 
  

   8 
  very 
  short, 
  bearing 
  four 
  longish 
  equal 
  bristles 
  ; 
  at 
  least 
  twenty 
  bristles 
  in 
  front 
  

   and 
  eight 
  to 
  nine 
  behind 
  the 
  stylets 
  ; 
  there 
  are 
  besides 
  six 
  to 
  eight 
  longer 
  bristles 
  

   on 
  the 
  ventral 
  edge, 
  overlapping 
  the 
  upper 
  sheath 
  of 
  the 
  ovipositor 
  (tergite 
  9). 
  

   Ovipositor 
  with 
  the 
  side-pieces 
  (from 
  sternite 
  8) 
  expanded 
  distally 
  and 
  ending 
  in 
  a 
  

   somewhat 
  long 
  acute 
  point. 
  They 
  do 
  not 
  share 
  in 
  the 
  serration 
  of 
  the 
  saw 
  proper, 
  

   which 
  bears 
  three 
  to 
  four 
  extremely 
  minute 
  apical 
  teeth 
  and 
  three 
  much 
  stouter 
  

   behind 
  ; 
  these 
  serrations 
  extend 
  only 
  over 
  the 
  apical 
  one-eighth 
  of 
  the 
  saw 
  (fig. 
  5, 
  c) 
  

   which 
  is 
  A 
  mm. 
  long 
  and 
  stout 
  basally. 
  The 
  sheath 
  (ninth 
  tergite) 
  is 
  rather 
  longer 
  

   than 
  the 
  saw, 
  and 
  the 
  distal 
  articulated 
  portion 
  is 
  two-ninths 
  of 
  the 
  whole 
  ; 
  each 
  

   free 
  lobe 
  bears 
  four 
  bristles 
  and 
  there 
  are 
  two 
  others 
  on 
  the 
  apex 
  of 
  the 
  fixed 
  portion 
  

   of 
  the 
  tergite.
