  a 
  long, 
  sharp 
  spine, 
  femora 
  broad 
  and 
  thick, 
  deeply 
  emarginate 
  

   beneath 
  ; 
  inner 
  part 
  of 
  tibiae 
  produced 
  inwardly 
  at 
  the 
  tip 
  into 
  a 
  

   compressed 
  lamina 
  dented 
  at 
  each 
  end 
  and 
  with 
  the 
  apical 
  Tipper 
  

   part 
  developed 
  inwardly 
  into 
  a 
  sharp 
  spine 
  reaching 
  as 
  far 
  as 
  the 
  

   base 
  of 
  the 
  fifth 
  joint 
  of 
  the 
  tarsi 
  the 
  four 
  basal 
  joints 
  of 
  which 
  are 
  

   distinct, 
  but 
  apparently 
  soldered, 
  the 
  fifth 
  joint 
  is 
  as 
  long 
  as 
  the 
  

   other 
  four, 
  and 
  has 
  three 
  not 
  very 
  distinct 
  denticulations 
  beneath, 
  

   the 
  claw 
  is 
  as 
  long 
  as 
  the 
  fifth 
  joint, 
  and 
  is 
  very 
  bluntly 
  dentate 
  

   underneath 
  ; 
  in 
  the 
  female 
  the 
  trochanters 
  are 
  also 
  spinose, 
  but 
  the 
  

   tibiae 
  are 
  not 
  much 
  inflated, 
  the 
  apical 
  spur 
  is 
  distinct, 
  whereas 
  in 
  

   the 
  male 
  it 
  has 
  disappeared 
  altogether 
  ; 
  the 
  four 
  joints 
  of 
  the 
  tarsi 
  

   are 
  elongate, 
  but 
  the 
  fifth 
  is 
  as 
  long 
  as 
  the 
  other 
  four, 
  tri-dentate 
  

   beneath 
  as 
  in 
  the 
  male, 
  and 
  the 
  claw 
  is 
  as 
  long 
  as 
  the 
  fifth 
  joint, 
  but 
  

   is 
  not 
  bluntly 
  dentate 
  beneath.
