  Remarks. 
  — 
  The

  almost 
  impunctate 
  surface 
  with 
  little 
  evidence

  alutaceous 
  dullness

  once 
  differentiates 
  this 
  from 
  Strabala 
  rufa 
  

   (lUiger). 
  There 
  are 
  no 
  records 
  of 
  it 
  farther 
  north 
  than 
  the 
  Brownsville 
  

   region.
