  ately 
  retreating; 
  interspace 
  between 
  the

   broad

  feebly 
  if 
  at 
  all 
  sulcate, 
  the 
  frontal 
  costa 
  

   distinctly 
  broadest 
  between 
  the 
  antennae, 
  where 
  it 
  is 
  nearly 
  as 
  wide 
  as 
  

   (male) 
  or 
  still 
  nnich 
  narrower 
  than 
  (female) 
  the 
  interspace 
  between 
  the 
  

   eyes, 
  percnrrent, 
  snlcate 
  at 
  least 
  below 
  the 
  ocellns; 
  ej-es 
  not 
  very 
  

   prominent 
  nor 
  very 
  large, 
  longer 
  in 
  proportion 
  to

  in 
  the 
  female 
  

   than 
  in 
  the 
  male, 
  and 
  yet 
  in 
  the 
  female 
  hardly, 
  in 
  the 
  male 
  distinctly, 
  

   longer 
  than 
  the 
  anterior 
  infraocular 
  portion 
  of 
  the 
  genae; 
  antennae 
  

   rather 
  coarse, 
  more 
  than 
  half 
  as 
  long 
  as 
  the 
  body 
  in 
  the 
  male, 
  distinctly 
  

   longer 
  than

  together 
  in 
  the 
  female. 
  Pronotum 
  snb- 
  

   eqnal 
  (male) 
  or 
  distinctly 
  and 
  very 
  gradually 
  broadening 
  posteriorly 
  

   (female), 
  with 
  a 
  rather 
  slight 
  median 
  carina, 
  sometimes 
  interrupted 
  

   between 
  the 
  sulci, 
  the 
  disk 
  very 
  broadly 
  subtectate. 
  passing 
  by 
  a 
  rounded 
  

   angle, 
  without 
  forming 
  lateral 
  carinae, 
  into

  (female) 
  or 
  sub- 
  

   vertical 
  (male) 
  lateral 
  lobes, 
  the

  margin 
  subtiuncate,

   flaring, 
  the 
  hind 
  margin 
  obtusely 
  angulate,

  rugulose 
  prozona 
  nearly 
  or 
  quite 
  half 
  as 
  long 
  again 
  as 
  the 
  punctate 
  

   or 
  distinctly 
  rugulose 
  metazona, 
  its 
  transverse 
  sulci 
  moderately 
  dis- 
  

   tinct, 
  that 
  in 
  the 
  middle 
  straight, 
  and 
  followed 
  a 
  third 
  of 
  the 
  way 
  to 
  

   the 
  metazoua 
  by 
  a 
  similar 
  but 
  arcuate 
  sulcus. 
  Prosternal 
  spine 
  blunt 
  

   conico-cylindrical, 
  more 
  or 
  less 
  retrorse; 
  interspace 
  between 
  mesoster- 
  

   nal 
  lobes 
  nearly 
  twice 
  as 
  long 
  (male) 
  or 
  half 
  as 
  long 
  again 
  (female) 
  as 
  

   broad, 
  the 
  inner 
  margins 
  of 
  the

  nearly 
  straight 
  : 
  metasternal 
  

   lobes 
  attingent 
  (male) 
  or 
  subattingent 
  (female). 
  Tegmiiia 
  abbreviated, 
  

   generally 
  but 
  not 
  always 
  a 
  little 
  longer 
  than 
  the 
  pronotum, 
  rounded 
  or 
  

   subacumiuate 
  at 
  tip, 
  their 
  inner 
  margins 
  overlapping 
  or 
  separated. 
  

   Fore 
  and 
  middle 
  femora 
  distinctly 
  gibbous 
  in 
  the 
  male; 
  hind 
  femora 
  

   variable, 
  as 
  also 
  the 
  coloring 
  of 
  the 
  inferior 
  genicular 
  lobe; 
  hind 
  tibiae 
  

   with 
  nine 
  to 
  ten, 
  generally 
  nine, 
  spines 
  in 
  the 
  outer 
  series. 
  Abdomen 
  

   of 
  male 
  very 
  feebly 
  clavate, 
  very 
  feebly 
  upturned, 
  the 
  lateral 
  margins 
  

   of 
  the 
  subgenital 
  plate 
  not 
  ampliate 
  at 
  the 
  base, 
  the 
  apex 
  bluntly 
  

   angulate 
  at 
  tip, 
  with 
  a 
  distinct 
  but 
  not 
  very 
  large 
  tubercle, 
  extending 
  

   beyond 
  the 
  inner 
  side 
  of 
  the 
  apical 
  margin 
  ; 
  furcula 
  consisting 
  of 
  a 
  pair 
  

   of 
  slight, 
  rounded, 
  feebly 
  projecting 
  lobes. 
  

  

  This 
  genus 
  is 
  closely 
  allied 
  to 
  Hijpochlora^ 
  but 
  is 
  composed 
  of 
  gener- 
  

   ally 
  stouter 
  forms, 
  in 
  which 
  the 
  antennae 
  are 
  longer, 
  the 
  i)ronotum 
  is 
  

   usually 
  rugulose 
  rather 
  than 
  punctate, 
  and 
  the 
  males 
  of 
  which 
  have 
  

   more 
  tumid 
  anterior 
  femora, 
  besides 
  the 
  differences 
  pointed 
  out 
  in 
  our 
  

   table 
  of 
  genera. 
  

  

  C. 
  acKfipennis 
  may 
  be 
  taken 
  as 
  the 
  type. 
  

  

  The 
  genus 
  occurs 
  only 
  in 
  the 
  West, 
  where 
  it 
  ranges 
  east 
  of 
  the 
  Eocky 
  

   Mountains 
  from 
  Nebraska 
  to 
  Texas, 
  and 
  occurs 
  again 
  in 
  Durango, 
  

   Mexico.
