  In 
  shape 
  the 
  insects 
  included 
  in 
  this 
  genus 
  greatly 
  resemble 
  small 
  

   species 
  of 
  Omocrates, 
  but 
  they 
  are 
  at 
  once 
  distinguished 
  by 
  the 
  shape 
  

   of 
  the 
  outer 
  teeth 
  of 
  the 
  anterior 
  tibiae 
  which 
  are 
  not 
  connate 
  and 
  not 
  

   set 
  at 
  right 
  angles 
  with 
  the 
  tibiae.
