  the 
  apex; 
  such 
  have 
  not 
  occurred 
  to 
  me; 
  immaculate 
  varieties 
  are 
  mentioned, 
  but 
  they 
  

   are 
  only 
  greasy 
  specimens, 
  in 
  which 
  vestiges 
  of 
  the 
  spot 
  can 
  always 
  be 
  traced. 
  

  

  GROUP 
  III. 
  

  

  Species 
  having 
  the 
  upper 
  surface 
  sericeous, 
  the 
  body 
  rather 
  flattened, 
  and 
  the 
  thorax 
  

   trapezoidal, 
  usually 
  short, 
  and 
  almost 
  margined. 
  The 
  head 
  is 
  glabrous, 
  the 
  vertex 
  is 
  

   broadly 
  excavated, 
  the 
  front 
  is 
  suddenly 
  declivous 
  anteriorly, 
  and 
  finely 
  striate. 
  The 
  la- 
  

   brum 
  is 
  large, 
  prominent, 
  sometimes 
  black 
  (in 
  foreign 
  species,) 
  and 
  one-toothed. 
  The 
  

   markings 
  of 
  the 
  elytra 
  are 
  variable, 
  but 
  the 
  terminal 
  part 
  of 
  the 
  apical 
  lunule 
  is 
  always 
  

   wanting, 
  the 
  apex 
  is 
  not 
  serrate 
  and 
  but 
  slightly 
  separately 
  rounded. 
  The 
  palpi 
  are 
  black 
  

   in 
  both 
  sexes 
  : 
  the 
  second 
  and 
  third 
  joints 
  of 
  the 
  anterior 
  tarsi 
  of 
  the 
  male 
  are 
  slightly 
  

   oblique. 
  The 
  body 
  is 
  hairy 
  beneath 
  on 
  the 
  sides; 
  in 
  other 
  respects 
  this 
  group 
  agrees 
  with 
  

   the 
  preceding. 
  

  

  The 
  species, 
  which 
  with 
  one 
  exception 
  are 
  foreign, 
  may 
  be 
  divided 
  as 
  follows: 
  

   Labrum 
  black, 
  carinated, 
  elytra 
  punctured 
  and 
  foveate. 
  C. 
  fasciato-punctata, 
  &c. 
  

   Labrum 
  white, 
  subcarinate. 
  

  

  Black, 
  elytra 
  more 
  densely 
  punctured, 
  hardly 
  margined. 
  C. 
  longilabris. 
  

   Green, 
  elytra 
  flattened, 
  margined. 
  C. 
  ismenia, 
  rotundicollis.

  New 
  Hampshire, 
  Canada, 
  Mackinaw, 
  Lake 
  Superior; 
  inhabits 
  paths 
  through 
  grassy 
  

   and 
  bushy 
  places, 
  and 
  takes 
  refuge 
  in 
  the 
  herbage 
  when 
  disturbed. 
  The 
  form 
  («) 
  is 
  a 
  

   female

  Superior, 
  of 
  a 
  pure 
  black 
  colour 
  above, 
  and 
  broader 
  

   form 
  than 
  usual; 
  the 
  thorax 
  is 
  less 
  narrowed 
  posteriorly. 
  

  

  GROUP 
  IV. 
  

  

  Robust 
  species 
  with 
  convex

  much 
  wider 
  than 
  its 
  

  

  length, 
  rounded 
  on 
  the 
  sides, 
  hardly 
  rugose, 
  not 
  granulate;

  foveas 
  

  

  near 
  the

  conjointly 
  broadly 
  rounded 
  at 
  tip, 
  not 
  serrate, 
  spots 
  always 
  marginal, 
  

  

  usually 
  small

  some 
  varieties 
  of 
  C,
