  The 
  type 
  in 
  the 
  LeConte 
  collection 
  bears 
  a 
  dark 
  green 
  circular 
  label 
  

   which 
  is 
  supposed 
  to 
  indicate 
  New 
  Mexico. 
  LeConte's 
  series 
  shows 
  

   considerable 
  variation 
  in 
  the 
  punctation 
  of 
  the 
  elytra, 
  the 
  striae 
  being 
  

   impressed 
  m 
  some 
  specimens. 
  There 
  is 
  also 
  great 
  variation 
  in 
  the 
  

   prominence 
  of 
  the 
  lateral 
  thoracic 
  tuberosities. 
  Specimens 
  have 
  been 
  

   examined 
  from 
  the 
  following 
  localities:

  The 
  apices 
  of 
  the 
  hind 
  tibiae 
  are 
  usually 
  rounded, 
  not 
  squarely 
  

   truncate, 
  although 
  in 
  some 
  specimens 
  they 
  are 
  definitely 
  obliquely 
  

   truncated. 
  In 
  color 
  tuberosus 
  varies 
  from 
  light, 
  aln.ost 
  unicolorous 
  

   gray, 
  sometimes 
  with 
  ocellate 
  plumbeous 
  spots 
  along 
  the 
  striae, 
  

   through 
  pinkish, 
  strongly 
  marked 
  with 
  chocolate 
  brown, 
  to 
  uniform 
  

   dull 
  brown 
  or 
  nearly 
  black. 
  The 
  median 
  sulcus 
  frequently 
  extends 
  up 
  

   onto 
  the 
  front. 
  So 
  much 
  variation 
  m 
  size, 
  punctation, 
  and 
  shape 
  

   exists 
  in 
  this 
  species 
  that 
  no 
  external 
  characters 
  can 
  be 
  given 
  other 
  

   than 
  those 
  mentioned 
  in 
  the 
  kev.
