   One 
  specimen 
  collected 
  at 
  Sacramento, 
  California, 
  by 
  Mr. 
  J. 
  Wittick, 
  and 
  given 
  me 
  

   by 
  Mr. 
  Rathvon. 
  Of 
  the 
  size 
  of 
  S. 
  vespertina, 
  but 
  less 
  dilated 
  behind. 
  The 
  clypeus 
  

   is 
  broader 
  in 
  front 
  than 
  in 
  any 
  of 
  the 
  preceding 
  species, 
  the 
  lateral 
  incisure 
  is 
  slight. 
  

   The 
  thorax 
  is 
  very 
  convex, 
  much 
  rounded 
  on 
  the 
  sides, 
  and 
  more 
  finely 
  punctured 
  

   than 
  in 
  the 
  others 
  ; 
  the 
  pectus 
  and 
  coxa? 
  are 
  uniformly 
  and 
  densely 
  punctured, 
  while 
  

   in 
  the 
  other 
  species 
  the 
  punctures 
  are 
  denser 
  on 
  the 
  coxas, 
  and 
  gradually 
  become 
  

   sparse 
  at 
  the 
  middle 
  of 
  the 
  pectus. 
  The 
  hairs 
  which 
  fringe 
  the 
  edge 
  of 
  the 
  thorax 
  

   and 
  elytra 
  are 
  longer 
  than 
  in 
  the 
  other 
  species.

  San 
  Diego, 
  California. 
  Of 
  the 
  same 
  size, 
  but 
  more 
  robust 
  than 
  S. 
  sericea, 
  and 
  very 
  

   distinct 
  by 
  the 
  more 
  oblique 
  sides 
  of 
  the 
  thorax 
  being 
  fringed 
  with 
  long 
  lateral 
  hairs, 
  

   and 
  by 
  the 
  hairy 
  breast. 
  The 
  stride 
  of 
  the 
  elytra 
  are 
  not 
  irregularly 
  punctured 
  as 
  

   usual, 
  but 
  have 
  only 
  single 
  rows 
  of 
  punctures. 
  It 
  is 
  possible 
  that 
  dark 
  colored 
  speci- 
  

   mens 
  may 
  occur, 
  as 
  mine, 
  although 
  found 
  flying 
  in 
  the 
  evening 
  twilight, 
  do 
  not 
  appear 
  

   to 
  have 
  become 
  fully 
  hardened.
