  It 
  is 
  interesting 
  to 
  find 
  a 
  member 
  of 
  the 
  genus 
  Taterillus 
  

   exhibiting 
  the 
  striking 
  coloration 
  met 
  with 
  in 
  this 
  species. 
  

   Although 
  agreeing 
  in 
  general 
  proportions 
  with

  conspicuous 
  dark 
  markings 
  on 
  the

  of 
  this 
  

   Eusso

  readily 
  distinguish 
  it 
  from
