  Larger

  narrower 
  than 
  the 
  next, 
  but 
  smaller 
  than 
  S- 
  

   fimbriata, 
  and 
  differing 
  from 
  both 
  by 
  the 
  clypeus 
  being 
  almost 
  rounded 
  in 
  front 
  

   without 
  distinct 
  lateral 
  angles, 
  as 
  well 
  as 
  by 
  the 
  form 
  of 
  the 
  thorax. 
  The 
  breast 
  is 
  

   more 
  hairy 
  than 
  usual, 
  though 
  less 
  so 
  than 
  in 
  S. 
  fimbriata, 
  and 
  the 
  hind 
  coxse 
  are 
  

   nearly 
  glabrous.

  Of 
  the 
  color 
  size 
  and 
  form 
  of 
  S. 
  sericea, 
  but 
  the 
  thorax 
  

   is 
  broader, 
  more 
  rounded 
  on 
  the

  and 
  more 
  strongly 
  fringed 
  : 
  the

  more 
  equally 
  scattered 
  over 
  the 
  interstices.

  One 
  specimen, 
  Oregon, 
  Col. 
  M'Call. 
  Closely 
  related 
  to 
  the 
  preceding, 
  but 
  seems 
  

   to 
  differ 
  in 
  the 
  slight 
  transverse 
  angulated 
  frontal 
  line, 
  and 
  the 
  sparsely 
  punctured 
  

   posterior 
  coxae 
  ; 
  the 
  elytra 
  are 
  more 
  deeply 
  striate 
  but 
  less 
  punctured, 
  and 
  the 
  pygidi- 
  

   um 
  is 
  more 
  finely 
  punctured.
