  Eagle 
  Pass, 
  Rio 
  Grande, 
  Texas 
  : 
  collected 
  by 
  Mr. 
  Schott 
  of 
  the 
  Boundary 
  Commission. 
  

   Nearly 
  related 
  to 
  the 
  preceding, 
  but 
  the 
  thorax 
  is 
  more 
  convex, 
  and 
  more 
  rounded 
  on 
  the 
  

   sides, 
  and 
  the 
  posterior 
  angles 
  fall 
  into 
  the 
  base 
  instead 
  of 
  being 
  prominent. 
  The 
  middle 
  

   band 
  of 
  the 
  elytra 
  is 
  about 
  as 
  sinuous 
  as 
  in 
  the 
  well 
  known 
  C. 
  limbalis, 
  (a 
  race 
  of 
  C.

  but 
  is 
  narrower 
  and 
  frequently 
  obsolete. 
  

  

  GROUP 
  II. 
  

  

  The 
  group 
  contains 
  one 
  species 
  of 
  a 
  somewhat 
  flattened 
  form, 
  and 
  dull 
  brownish 
  colour, 
  

   above 
  almost 
  without 
  metallic 
  reflections. 
  The 
  labrum 
  is 
  large, 
  prominent 
  in 
  the 
  mid- 
  

   dle, 
  with 
  three 
  distinct 
  teeth 
  ; 
  the 
  outer 
  angles 
  are 
  very 
  obtuse. 
  The 
  palpi 
  of 
  both 
  sexes 
  

   are 
  entirely 
  black. 
  The 
  front 
  is 
  flattened, 
  finely 
  wrinkled, 
  and 
  striate 
  towards 
  the 
  eyes, 
  

   entirely 
  bald; 
  the 
  surface 
  of 
  the 
  head 
  and 
  thorax 
  is 
  distinctly 
  granulate. 
  Thorax 
  flat- 
  

   tened, 
  trapezoidal. 
  Elytra 
  not 
  serrate 
  at 
  tips, 
  which 
  are 
  separately 
  acutely 
  rounded, 
  

   without 
  any 
  sutural 
  spine 
  : 
  the 
  punctures 
  are 
  large 
  and 
  shallow, 
  the 
  markings 
  marginal, 
  

   frequently 
  wanting. 
  Body 
  beneath 
  glabrous. 
  Eyes 
  rather 
  small, 
  but 
  prominent.

  found 
  in 
  paths 
  in 
  shady, 
  hilly 
  woods 
  in 
  May 
  or 
  June, 
  

   according 
  to 
  the

  of 
  the 
  locality: 
  the

  of 
  discovering 
  a 
  locality 
  in 
  the 
  imme- 
  

   diate 
  neighbourhood 
  of 
  Philadelphia 
  is 
  due 
  to 
  Mr. 
  Schafhirt.
