  of 
  the 
  valley, 
  20 
  miles 
  south 
  of 
  Furnace 
  Creek 
  Ranch. 
  The 
  National 
  

   Museum 
  collection 
  contains 
  several 
  old 
  examples 
  of 
  californicus 
  from 
  

   Death 
  Valley, 
  and 
  two 
  from 
  "Ariz.," 
  all 
  of 
  which 
  were 
  found 
  mixed 
  

   in 
  with 
  the 
  series 
  of 
  desertus; 
  in 
  addition 
  several 
  paratypes 
  of 
  cali- 
  

   fornicus 
  are 
  at 
  hand, 
  presented 
  to 
  the 
  National 
  Museum 
  by 
  Mr. 
  Ting. 
  

   Ting's 
  species 
  is 
  quite 
  distinct 
  from 
  desertus, 
  though 
  the 
  two 
  are 
  

   closely 
  related. 
  Of 
  several 
  characters 
  of 
  californicus 
  pointed 
  out 
  by 
  

   Ting, 
  in 
  which 
  it 
  differs 
  from 
  desertus, 
  the 
  following 
  were 
  foimd 
  es- 
  

   pecially 
  useful: 
  The 
  more 
  or 
  less 
  distinctly 
  speclded 
  elytra, 
  the 
  shal- 
  

   lower 
  serial 
  punctures 
  on 
  the 
  elytra, 
  the 
  obscuring 
  of 
  the 
  tenth 
  row 
  

   of 
  punctures 
  by 
  the 
  scaly 
  vestiture, 
  the 
  shape 
  of 
  the 
  median 
  lobe 
  of 
  

   the 
  male 
  genitalia 
  (figured 
  by 
  Ting), 
  and, 
  particularly 
  in 
  the 
  female, 
  

   the 
  greater 
  convexity 
  of 
  the 
  fifth 
  abdominal 
  sternite. 
  In 
  addition, 
  

   when 
  the 
  two 
  species 
  are 
  compared 
  in 
  series, 
  californicus 
  is 
  seen 
  to 
  be 
  

   considerably 
  smaller, 
  rangmg 
  from 
  10.5 
  to 
  17 
  mm. 
  in 
  length 
  (teste 
  

   Ting), 
  whereas 
  desertus 
  is 
  from 
  about 
  14 
  to 
  22 
  mm. 
  long. 
  Davis's 
  

   redescription 
  of 
  desertus 
  was 
  evidently 
  based 
  chiefly 
  on 
  specimens 
  of 
  

   this 
  species, 
  though 
  included 
  in 
  it 
  were 
  a 
  few 
  statements 
  of 
  exception 
  

   and 
  qualification 
  that 
  obviously 
  referred 
  to 
  californicus. 
  After 
  the 
  

   elimination 
  of 
  these 
  inapplicable 
  portions, 
  Davis's 
  description 
  fits 
  

   desertus 
  well 
  enough.]

  Eupagoderes 
  geminatus 
  Horn, 
  1876, 
  p. 
  35. 
  

  

  Robust, 
  elytra 
  moderately 
  inflated; 
  color 
  variable 
  but 
  predomi- 
  

   nantly 
  gray; 
  head 
  usually 
  with 
  a 
  median 
  line 
  and 
  a 
  space 
  in 
  front 
  of 
  

   each 
  eye 
  dark 
  brown 
  or 
  plumbeous; 
  markings 
  of 
  elytra 
  variable, 
  but 
  

   usually 
  light 
  gray, 
  intervals 
  2, 
  4, 
  and 
  6 
  darker. 
  Sometimes 
  interval 
  1 
  

   is 
  also 
  dark. 
  Some 
  specimens 
  are 
  dark 
  gray 
  irrorate 
  with 
  darker 
  gray 
  

   or 
  black, 
  and 
  others 
  have 
  the 
  even 
  numbered 
  elytral 
  intervals 
  only 
  

   slightly 
  darker, 
  with 
  irregular 
  paired 
  spots 
  of 
  gray 
  or 
  black 
  in 
  the 
  

   striae, 
  one 
  on 
  each 
  side 
  of 
  the 
  interval. 
  Specimens 
  from 
  Overton, 
  

   Nev., 
  have 
  the 
  suture 
  and 
  some 
  of 
  the 
  markings 
  on 
  the 
  head, 
  thorax, 
  

   and 
  elytra 
  light 
  brown. 
  However 
  marked, 
  the 
  third 
  elytral 
  interval 
  

   is 
  nearly 
  always 
  conspicuously 
  lighter. 
  Rostrum 
  moderately 
  stout, 
  

   constricted* 
  at 
  base 
  beneath; 
  median 
  sulcus 
  fine, 
  sharp; 
  lateral 
  sulci 
  

   short, 
  evenly 
  arcuate, 
  sometimes 
  subobsolete. 
  Transverse 
  impression 
  

   vague, 
  sometimes 
  nearly 
  obsolete. 
  Head 
  rounded, 
  front 
  slightly 
  

   flattened; 
  head 
  and 
  rostrum 
  finely 
  and 
  sparsely 
  punctate. 
  Pronotum 
  

   one-fourth 
  or 
  slightly 
  more 
  than 
  one-fourth 
  wider 
  than 
  long, 
  base 
  

   one-sixth 
  to 
  two-sevenths 
  wider 
  than 
  apex; 
  sides 
  evenly 
  rounded; 
  

   disk 
  varying 
  from 
  nearly 
  impunctate 
  to 
  coarsely, 
  closely 
  punctate; 
  in 
  

  

  ' 
  The 
  constriction, 
  in 
  ttiis 
  and 
  in 
  other 
  species, 
  is 
  not 
  always 
  apparent, 
  at 
  least 
  with 
  the 
  scales 
  in 
  place.
