  of 
  these 
  specimens 
  is 
  somewhat 
  longer 
  than 
  suggested 
  by 
  Provan- 
  

   cher's 
  description, 
  and 
  the 
  type 
  may 
  be 
  a 
  different 
  species, 
  but 
  the 
  

   agreement 
  of 
  the 
  antennae, 
  and 
  of 
  the 
  structure, 
  sculpture 
  and 
  color 
  

   of 
  the 
  thorax, 
  is 
  striking.
