   and 
  the

  a 
  

   conspicuous 
  mucro-like 
  tooth, 
  there 
  is 
  a 
  small 
  apical 
  spur, 
  and 
  the 
  

   angles

  the 
  tibia

  side

  tooth

   the 
  anterior 
  tibiae 
  obliterated

   simple. 
  

  

  Female

  the 
  prothorax 
  is 
  covered 
  with 
  appressed 
  

   squamose 
  hairs 
  instead 
  of 
  scales, 
  and 
  the 
  apical 
  spur 
  is 
  more 
  

   developed.
