  Eupagoderes 
  marmoratus 
  Fall, 
  1910, 
  p. 
  191. 
  

  

  This 
  species 
  is 
  very 
  closely 
  related 
  to 
  E. 
  nivosus 
  Fall, 
  and 
  resembles 
  

   it 
  closely 
  in 
  shape. 
  It 
  is 
  distinguished 
  chiefly 
  by 
  being 
  strongly 
  

   mottled 
  with 
  ocellate 
  black 
  spots, 
  especially 
  along 
  the 
  elytral 
  striae, 
  

   by 
  having 
  the 
  rostrum 
  usually 
  more 
  deeply 
  sulcate, 
  and 
  the 
  pronotum 
  

   more 
  coarsely 
  and 
  closely 
  punctate. 
  In 
  some 
  specimens 
  the 
  median 
  

   sulcus 
  of 
  the 
  rostrum 
  continues 
  up 
  onto 
  the 
  front 
  nearly 
  to 
  the 
  vertex, 
  

   in 
  wliich 
  case 
  it 
  is 
  usually 
  in 
  the 
  center 
  of 
  a 
  median 
  brown 
  stripe. 
  The 
  

   lateral 
  sulci 
  may 
  be 
  evenly 
  arcuate 
  or 
  straight 
  apically, 
  and 
  are 
  rather

  Eupagoderes 
  marmoratus 
  Fall: 
  a, 
  Female 
  genital 
  tube, 
  dorsal 
  view; 
  b, 
  female 
  

   genital 
  tube, 
  ventral 
  view; 
  c, 
  female 
  genital 
  tube, 
  lateral 
  view 
  (dorsal 
  side 
  to 
  left); 
  d, 
  

   median 
  lobe 
  of 
  male 
  genitalia, 
  dorsal 
  and 
  lateral 
  views. 
  

  

  sharply 
  convergent 
  near 
  the 
  base 
  of 
  the 
  rostrum. 
  In 
  many 
  specimens 
  

   the 
  ridges 
  between 
  the 
  sulci 
  are 
  so 
  pronounced 
  that 
  the 
  head 
  and 
  

   rostrum 
  have 
  separate 
  convexities 
  as 
  viewed 
  from 
  the 
  side, 
  giving 
  the 
  

   illusion 
  of 
  a 
  transverse 
  impression 
  between 
  head 
  and 
  rostrum. 
  The 
  

   pronotum 
  is 
  usually 
  a 
  little 
  more 
  than 
  one-fifth 
  wider 
  than 
  long, 
  and 
  

   varies 
  from 
  moderately 
  coarsely, 
  sparsely 
  punctate 
  to 
  coarsely 
  and 
  

   closely 
  punctate. 
  In 
  most 
  specimens 
  the 
  prothorax 
  at 
  the 
  sides 
  is 
  

   so 
  densely 
  punctate 
  that 
  the 
  punctures 
  coalesce, 
  and 
  there 
  are 
  small 
  

   but 
  very 
  evident 
  tuberosities 
  present. 
  The 
  spots 
  upon 
  the 
  elytra 
  are
