  in 
  Durango 
  ; 
  Guanajuato 
  ; 
  Jalapa 
  ; 
  

   Chihuahua 
  City 
  ; 
  Nuevo 
  Laredo, 
  in 
  Tamaulipas 
  ; 
  Paso 
  

   del 
  Norte, 
  in 
  Chihuahua 
  (Hoge). 
  

  

  Distinctly 
  shorter 
  and 
  broader 
  than 
  C. 
  peregrinator 
  ; 
  

   black, 
  moderately 
  shining, 
  the 
  triple 
  row 
  of 
  small 
  foveas 
  

   and 
  the 
  margins 
  of 
  the 
  elytra, 
  in 
  fresh 
  examples, 
  

   metallic-green. 
  The 
  head 
  is 
  finely 
  punctured, 
  the 
  fore- 
  

   head 
  also 
  coriaceous 
  ; 
  the 
  mandibles 
  densely 
  rugose 
  and 
  

   punctured 
  ; 
  the 
  tooth 
  of 
  the 
  mentum 
  narrower 
  and 
  more 
  

   deflected 
  than 
  in 
  C. 
  ]jeregrinator 
  and 
  the 
  allied 
  species, 
  

   so 
  that 
  it 
  is 
  often 
  invisible, 
  without 
  dissecting 
  the 
  mouth. 
  

   The 
  thorax 
  is 
  transverse-ovate, 
  the 
  sides 
  strongly 
  

   rounded, 
  widest 
  near 
  the 
  middle 
  ; 
  the 
  hind 
  angles 
  as 
  in 
  

   C. 
  peregrinator, 
  much 
  deflected 
  ; 
  the 
  thickened 
  margin 
  

   much 
  lowered 
  and 
  thinner 
  at 
  the 
  extreme 
  apex, 
  which 
  

   is 
  moderately 
  acute 
  ; 
  the 
  disk 
  coriaceous 
  or 
  smooth, 
  

   sides 
  and 
  base 
  sparingly 
  punctured. 
  The 
  elytra 
  are 
  

   oblong, 
  scarcely 
  widened 
  behind, 
  finely 
  striate-punctate 
  

   and 
  triseriate-foveate. 
  Beneath, 
  the 
  metathoracic 
  epi- 
  

   sterna 
  and 
  sides 
  of 
  basal 
  ventral 
  segments 
  are 
  sparingly 
  

   punctured. 
  The 
  legs 
  are 
  rather 
  shorter 
  and 
  stouter 
  than 
  

   in 
  C. 
  peregrinator, 
  and 
  the 
  three 
  dilated 
  joints 
  of 
  the 
  

   anterior 
  tarsi 
  in 
  the 
  3' 
  are 
  short 
  and 
  broad, 
  the 
  2nd 
  and 
  

   3rd 
  nearly 
  twice 
  as 
  broad 
  as 
  long. 
  

  

  C. 
  peregrinator 
  (Guer. 
  = 
  carhonatum, 
  Lee. 
  sec. 
  Horn) 
  

   is 
  found 
  in 
  the 
  same 
  localities. 
  Chihuahua 
  and 
  Durango, 
  

   as 
  C. 
  ampliator, 
  but 
  appears 
  to 
  be 
  more 
  common.

  This 
  species, 
  like 
  the 
  preceding, 
  is 
  an 
  addition

  the 
  

   Mexican 
  fauna.

   Dejean's 
  description
