  scutellar 
  suture. 
  Metanotum 
  smooth, 
  in 
  some 
  some 
  specimens 
  with 
  a 
  

   trace 
  of 
  a 
  percurrent 
  carina 
  in 
  the 
  mid 
  area. 
  Propodeon 
  smooth, 
  median 
  carina 
  

   broad, 
  spiracle 
  large, 
  broadly 
  oval 
  (lying 
  forward 
  on 
  the

  only 
  

   a

  median 
  carina 
  ; 
  one 
  longish 
  bristle 
  at 
  

   the 
  edge 
  of 
  the 
  spiracle 
  anterolaterally,

  spiracle 
  and 
  the 
  postero- 
  

   lateral 
  angle. 
  There 
  are 
  no 
  lateral 
  folds 
  ; 
  at 
  most 
  a 
  short 
  spur 
  is, 
  in 
  some 
  specimens, 
  

   given 
  off 
  from 
  the 
  lateral 
  edge 
  on 
  each 
  side 
  of 
  the 
  mid 
  line. 
  Mesosternopleurae 
  

   nearly 
  all 
  smooth, 
  but 
  the 
  upper 
  two-thirds

  show 
  a 
  rather 
  coarse, 
  

   slightly 
  raised 
  pattern.

  the 
  edge 
  and 
  the 
  same
