  two 
  short 
  angular 
  projections

  two

  At 
  the 
  metanotal

  the 
  median 
  keels 
  are 
  from 
  one 
  

   another 
  about 
  one-seventh 
  of 
  the 
  distance 
  between 
  the 
  laterals, 
  but 
  posteriorly 
  they 
  

   diverge 
  considerably, 
  till 
  at 
  the 
  posterior 
  edge 
  they 
  are

  distance 
  between 
  the 
  lateral 
  keels. 
  An 
  area 
  is 
  thus 
  enclosed 
  in 
  which 
  there 
  rises 
  

   a 
  slight 
  median 
  keel, 
  flanked 
  by 
  two 
  hollows 
  separated 
  slightly 
  from 
  one 
  another. 
  

   The 
  short 
  stalk 
  of 
  the 
  propodaeum 
  is 
  at 
  first 
  a 
  little 
  depressed, 
  then 
  raised. 
  Thus, 
  

   the 
  keel 
  or 
  ridge 
  separating 
  the 
  hollows 
  fails 
  before 
  the 
  extreme 
  apex 
  of 
  the 
  

   propodaeum. 
  Stigma 
  oval, 
  rimmed 
  (fig. 
  9, 
  a); 
  pleurae 
  shining 
  green, 
  reticulate.
