  Orientalia. 
  

  

  shining. 
  Thorax 
  thickly 
  covered 
  with 
  stiff 
  black 
  hair 
  ; 
  

   the 
  pronotum 
  broadly 
  at 
  the 
  apex, 
  and 
  the 
  lower 
  side 
  

   of 
  the 
  mesopleurai 
  in 
  the 
  middle, 
  thickly 
  covered 
  with 
  

   silvery 
  pubescence. 
  Mesonotum 
  strongly 
  and 
  deeply 
  

   punctured 
  ; 
  the 
  furrows 
  are 
  deep 
  ; 
  between 
  them 
  is 
  a 
  keel 
  

   which 
  is 
  smooth 
  and 
  shining, 
  and 
  extends 
  to 
  near 
  the 
  

   base. 
  Scutellum 
  rugosely 
  punctured, 
  its 
  middle 
  smooth, 
  

   bare 
  and 
  shining 
  ; 
  at 
  its 
  base 
  is 
  an 
  oval 
  fovea 
  ; 
  its 
  apex 
  

   is 
  slightly 
  depressed 
  ; 
  the 
  smooth 
  part 
  projects 
  over 
  the 
  

   apex, 
  which 
  has 
  a 
  long, 
  sharply 
  oblique 
  slope. 
  The 
  base 
  

   of 
  the 
  median 
  segment 
  is 
  raised 
  and 
  has 
  a 
  perpen- 
  

   dicular 
  slope, 
  and 
  is 
  separated 
  from 
  the 
  mesothorax 
  by 
  a 
  

   wide 
  deep 
  space 
  ; 
  the 
  segment 
  is 
  opaque, 
  coarsely 
  aluta- 
  

   ceous, 
  not 
  reticulated, 
  and 
  is 
  sparsely 
  covered, 
  particularly 
  

   at 
  the 
  sides, 
  with 
  long 
  black 
  hairs 
  ; 
  the 
  central 
  furrow 
  is 
  

   depressed 
  at 
  the 
  base, 
  where 
  it 
  is 
  furrowed 
  in 
  the 
  middle 
  ; 
  

   it 
  reaches 
  to 
  the 
  top 
  of 
  the 
  slope, 
  becoming 
  gradually 
  

   narrower 
  ; 
  the 
  keels 
  are 
  raised 
  at 
  its 
  apex 
  and 
  are 
  there 
  

   smooth 
  and 
  shining 
  ; 
  the 
  apex 
  has 
  an 
  almost 
  perpen- 
  

   dicular 
  slope, 
  and 
  is 
  rounded 
  at 
  the 
  top. 
  Propleurae 
  

   rugose, 
  the 
  middle 
  bearing 
  stout 
  striae, 
  the 
  apex 
  smooth. 
  

   Mesopleurae 
  broadly 
  tuberculate 
  at 
  top 
  and 
  bottom, 
  

   opaque, 
  alutaceous, 
  and 
  covered 
  with 
  black 
  hairs 
  ; 
  the 
  

   upper 
  half 
  of 
  the 
  metapleurae 
  reticulated, 
  the 
  lower 
  

   smooth. 
  Legs 
  thickly 
  covered 
  with 
  black 
  hair 
  ; 
  the 
  fore 
  

   calcaria 
  pale. 
  Abdomen 
  ferruginous, 
  the 
  petiole 
  and 
  two- 
  

   thirds 
  of 
  the 
  apical 
  segment 
  black 
  ; 
  the 
  petiole 
  strongly 
  

   punctured 
  and 
  covered 
  with 
  long 
  black 
  hair, 
  as 
  is 
  also 
  the 
  

   base 
  of 
  the 
  second 
  segment 
  ; 
  the 
  apex 
  of 
  the 
  second, 
  and 
  

   the 
  third 
  to 
  sixth 
  segments, 
  thickly 
  covered 
  with 
  long 
  

   orange 
  pubescence 
  ; 
  the 
  black 
  part 
  of 
  the 
  last 
  segment 
  is 
  

   covered 
  with 
  black 
  hairs; 
  its 
  middle 
  is 
  smooth 
  and 
  bare, 
  

   the 
  apical 
  half 
  of 
  the 
  ventral 
  keel 
  projects 
  as 
  an 
  oblique, 
  

   somewhat 
  triangular 
  tooth, 
  rounded 
  at 
  the 
  apex 
  ; 
  the
