  In 
  this 
  species 
  there 
  is 
  a 
  great 
  deal 
  of 
  variation 
  in 
  size, 
  shape, 
  and 
  

   degree 
  of 
  niaciilation. 
  Some 
  specimens 
  are 
  robust, 
  convex, 
  the 
  body 
  

   dihitod 
  and 
  widest 
  behind 
  the 
  middle, 
  others 
  are 
  flatter 
  and 
  more 
  

   parallel, 
  with 
  the 
  body 
  widest 
  at 
  about 
  the 
  middle. 
  The 
  color 
  varies 
  

   from 
  ahiiost 
  uniform 
  gray 
  with 
  blotches 
  of 
  white 
  upon 
  the 
  elytra, 
  

   through 
  gray 
  distinctly 
  marked 
  with 
  brown 
  and 
  white, 
  to 
  a 
  nearly 
  

   uniform 
  muddy 
  brown. 
  One 
  median 
  and 
  two 
  lateral 
  vittae 
  of 
  darker 
  

   color 
  upon 
  the 
  pronotum 
  are 
  sometimes 
  faint, 
  but 
  seem 
  always 
  to 
  be 
  

   present. 
  The 
  median 
  sulcus 
  of 
  the 
  rostrum 
  is 
  usually, 
  but 
  not 
  always, 
  

   represented 
  by 
  an 
  obsolete 
  fovea 
  about 
  opposite 
  the 
  artennal 
  inser- 
  

   tion. 
  At 
  times 
  a 
  median 
  sulcus 
  may 
  be 
  faintly 
  suggested 
  by 
  a 
  fine 
  

   impressed 
  Une 
  extending 
  backward 
  from 
  the 
  fovea.

   The 
  ridges 
  between 
  the 
  sulci 
  vary 
  from 
  obsolete 
  to 
  higii 
  and 
  sharp. 
  

   In 
  tin' 
  latter 
  case 
  their 
  sudden 
  rise 
  at 
  tiic 
  base 
  of 
  the 
  rostrum 
  gives 
  

   the 
  j)rofile 
  the 
  appearance 
  of 
  h»iving 
  a 
  slight 
  transverse 
  inijjression 
  

   between 
  head 
  and 
  rostrum, 
  'i'he 
  ridges 
  abov(> 
  and 
  in

   eyes 
  are 
  pronounced. 
  The 
  i)un(lHlion 
  of 
  the 
  |)ronotinn 
  varies 
  from 
  

   coarse 
  and 
  rather 
  close 
  to 
  practically 
  absent. 
  As 
  a 
  rule 
  it 
  is 
  fairly 
  

   coarse 
  and 
  moderately 
  close, 
  coarser 
  and 
  closer 
  at 
  the 
  sides. 
  The 
  

   elytral 
  striae 
  are 
  line 
  but 
  distinct,
