  The 
  U. 
  S. 
  National 
  Museum 
  collection 
  contains 
  several 
  specimens 
  

   from 
  Death 
  Valley, 
  Calif.; 
  also, 
  one 
  which 
  appears 
  at 
  first 
  glance 
  to 
  

   be 
  an 
  abnormal 
  specimen 
  of 
  E. 
  desertus 
  Horn, 
  from 
  which 
  it 
  differs 
  

   externally 
  in 
  the 
  impressed 
  elytral 
  striae, 
  the 
  more 
  impunctate, 
  

   smoother 
  appearance, 
  and 
  the 
  fulvous 
  suture. 
  It 
  is 
  dark 
  grayish 
  

   yellow, 
  with 
  conspicuous 
  irregularly 
  placed 
  ocellate 
  spots 
  of 
  deep 
  

   brown 
  along 
  the 
  striae.

  Remarks. 
  — 
  The 
  female 
  genitalia 
  of 
  E. 
  mortivallis 
  differ 
  from 
  those 
  

   of 
  E. 
  desertus 
  chiefly 
  in 
  the 
  apical 
  plates, 
  which 
  are 
  nearly 
  horizontal 
  

   from 
  side 
  to 
  side 
  and 
  concave 
  beneath, 
  not 
  tilted 
  upward 
  at 
  their 
  

   lateral 
  edges 
  and 
  nearly 
  flat, 
  and 
  in 
  the 
  coxites' 
  being 
  more 
  rounded 
  as 
  

   viewed 
  from 
  the 
  side. 
  The 
  male 
  median 
  lobe 
  is 
  thinner, 
  sharper 
  at 
  

   apex, 
  and 
  not 
  squarely 
  truncate 
  as 
  in 
  desertus. 
  E. 
  mortivallis 
  is 
  

   more 
  closely 
  related 
  to 
  E. 
  geminatus 
  Horn, 
  from 
  wliich 
  it 
  may 
  be 
  

   distinguished 
  by 
  its 
  size 
  and 
  color.
