  is 
  a 
  broad, 
  deep 
  depression 
  having 
  a 
  stout 
  

   keel 
  in

  the 
  base 
  ; 
  the 
  post-scutellum 
  de- 
  

   pressed 
  ; 
  its 
  sides 
  stoutly

  The 
  base 
  of 
  the 
  median 
  

   segment 
  is 
  sharply 
  depressed 
  ; 
  oblique, 
  stoutly

  outer 
  keel 
  being 
  

   joined 
  at 
  its 
  apex 
  by 
  a 
  curved 
  one 
  of 
  similar 
  size 
  which 
  

   proceeds 
  from 
  the 
  basal 
  keel 
  on 
  the 
  inner 
  side 
  of 
  the 
  

   spiracles, 
  these 
  being 
  thus 
  enclosed 
  ; 
  at 
  the 
  apex 
  of 
  this, 
  

   and 
  united

  stout 
  L-shaped 
  keel, 
  from 
  which 
  two 
  

   stout 
  keels 
  run 
  to 
  the 
  apex 
  of 
  the 
  segment.
