  This 
  and 
  the 
  next 
  following 
  species 
  differ 
  from 
  all 
  others 
  known 
  to 
  

   me 
  in 
  lacking 
  any 
  trace 
  of 
  angulation 
  of 
  the 
  tumid 
  humeral 
  margin 
  

   of 
  the 
  pronotum; 
  and 
  the 
  present 
  species 
  is 
  unique 
  in 
  the 
  genus 
  for 
  

   its 
  red 
  head 
  and 
  is 
  very 
  unusual 
  in 
  its 
  lack 
  of 
  a 
  pale 
  annulus 
  on 
  the 
  

   antenna.
