  The 
  foregoing 
  description 
  is 
  that 
  of 
  the 
  male 
  type. 
  The 
  only 
  other 
  

   specimen 
  known 
  to 
  me 
  is 
  a 
  female 
  in 
  the 
  collection 
  of 
  the 
  U. 
  S. 
  Na- 
  

   tional 
  Museum. 
  This 
  specimen, 
  while 
  undoubtedly 
  of 
  the 
  same 
  

   species, 
  differs 
  from 
  the 
  type 
  rather 
  markedly 
  in 
  some 
  respects. 
  The 
  

   front 
  of 
  the 
  head 
  is 
  greatly 
  depressed, 
  with 
  a 
  median 
  groove 
  reaching 
  

   to 
  the 
  vortex; 
  elytra 
  produced 
  at 
  base; 
  humeri 
  rounded 
  but 
  prominent; 
  

   elytra 
  intervals 
  1 
  and 
  3 
  narrower 
  than 
  2 
  and 
  4 
  and 
  elevated, 
  intervals 
  

   5, 
  6, 
  and 
  7 
  slightly 
  wider 
  than 
  1 
  and 
  3 
  and 
  greatly 
  elevated, 
  so 
  that 
  

   the 
  sides 
  of 
  the 
  elytra 
  are 
  vertical. 
  The 
  predominating 
  color 
  is 
  buff 
  

   or 
  light 
  brown, 
  with 
  gray 
  or 
  dark 
  brown 
  markings.
