  are 
  some 
  stout, 
  longitudinal 
  keels. 
  In 
  the 
  middle 
  of 
  the 
  

   median 
  segment 
  is 
  a 
  stout 
  keel 
  running 
  from 
  the 
  base 
  

   (where 
  it 
  is 
  rounded) 
  to 
  shortly 
  beyond 
  the 
  middle 
  of 
  the 
  

   segment, 
  outside 
  this 
  is 
  a 
  similar 
  keel 
  which 
  surrounds 
  its 
  

   apical 
  two-thirds 
  ; 
  outside 
  this 
  again 
  is 
  another 
  originating 
  

   at 
  the 
  same 
  place, 
  but 
  proceeding 
  to 
  the 
  end 
  of 
  the 
  segment, 
  

   where 
  they 
  are 
  joined 
  by 
  a 
  transverse 
  keel 
  ; 
  between 
  the 
  

   two 
  are 
  a 
  few 
  irregular 
  transverse 
  keels, 
  and, 
  at 
  the 
  apex 
  

   in 
  the 
  middle, 
  is 
  a 
  longitudinal 
  one 
  ; 
  from 
  the 
  outer 
  side 
  

   at 
  the 
  base 
  a 
  stout 
  keel 
  runs 
  obliquely 
  to 
  the 
  middle, 
  

   and 
  having 
  on 
  its 
  inner 
  side 
  near 
  the 
  apex 
  three 
  short, 
  

   stout 
  keels 
  ; 
  on 
  the 
  side, 
  shortly 
  beyond 
  the 
  middle, 
  is 
  

   a 
  large, 
  stout 
  tooth 
  ; 
  from 
  its 
  sides 
  run 
  obliquely 
  two 
  

   keels 
  to 
  the 
  oblique 
  inner 
  keel 
  ; 
  behind, 
  two 
  stout 
  keels 
  

   run 
  to 
  the 
  apex 
  of 
  the 
  segment 
  ; 
  inside 
  of 
  which 
  are 
  two 
  

   shorter 
  keels 
  united 
  to 
  the 
  apical 
  transverse 
  terminal 
  keel. 
  

   The 
  propleurae 
  largely 
  and 
  acutely 
  margined 
  in 
  front 
  and 
  

   below, 
  projecting 
  at 
  the 
  base 
  into 
  a 
  large, 
  triangular 
  tooth 
  ; 
  

   at 
  the 
  base 
  is 
  an 
  oblique 
  keel, 
  and, 
  in 
  the 
  middle, 
  three 
  

   larger, 
  stouter, 
  curved 
  keels, 
  at 
  the 
  apex 
  above 
  are 
  three 
  

   short 
  keels 
  ; 
  below 
  these 
  are 
  five 
  larger 
  ones, 
  the 
  central 
  

   being 
  much 
  longer 
  than 
  the 
  others. 
  The 
  presternum 
  is 
  

   bordered 
  above 
  by 
  a 
  stout 
  keel. 
  Mesopleurae 
  smooth 
  ; 
  

   below 
  is 
  a 
  wide 
  depression, 
  extending 
  from 
  near 
  the 
  base 
  

   to 
  the 
  apex, 
  where 
  it 
  gets 
  narrower 
  and 
  deeper 
  ; 
  at 
  its 
  

   base 
  are 
  some 
  keels 
  ; 
  the 
  apical 
  depression 
  is 
  crenulated. 
  

   Metapleurae 
  smooth 
  ; 
  the 
  upper 
  and 
  lower 
  part 
  at 
  the 
  base 
  

   widely 
  furrowed 
  ; 
  the 
  depression 
  on 
  the 
  top 
  surrounded 
  

   by 
  a 
  stout 
  keel 
  ; 
  the 
  lower 
  part 
  is 
  more 
  deeply 
  and 
  

   widely 
  depressed 
  and 
  more 
  stoutly 
  keeled 
  beneath 
  ; 
  at 
  the 
  

   apex 
  in 
  the 
  middle 
  are 
  four 
  keels 
  which 
  become 
  gradually 
  

   longer. 
  Legs 
  thickly 
  pilose 
  ; 
  the 
  apical 
  joint 
  of 
  the 
  

   posterior 
  trochanters 
  rufous. 
  The 
  basal 
  segment 
  of 
  the 
  

   abdomen 
  black 
  above, 
  broadly 
  white 
  down 
  the 
  sides 
  and
