  This 
  species 
  differs 
  from 
  all 
  others 
  in 
  the 
  genus 
  by 
  its 
  small 
  size, 
  

   color 
  markings, 
  and 
  male 
  genitaUa. 
  It 
  is 
  easily 
  distinguished 
  from 
  

   Fvlvius 
  lunulatus 
  Uhler, 
  1891, 
  by 
  its 
  color 
  pattern 
  of 
  the 
  head 
  and 
  

   pronotum. 
  These 
  structures 
  are 
  uniformly 
  dark 
  in 
  the 
  latter 
  species.
