  Of 
  rather 
  small 
  or 
  medium 
  size, 
  brownisli

  with 
  a 
  ferruginous 
  tinge.

  a 
  little 
  prominent, 
  dark 
  

   testaceous 
  often 
  somewhat 
  infuscated, 
  above 
  much 
  infuscated, 
  the 
  

   added 
  infuscation 
  sometimes 
  confined 
  to 
  the 
  fastigium 
  and 
  two 
  diverg- 
  

   ent, 
  enlarging 
  streaks 
  behind 
  it; 
  vertex 
  gently 
  tumid, 
  feebly 
  elevated 
  

   above 
  the 
  level 
  of 
  the 
  pronotum, 
  the 
  interspace 
  between 
  the 
  eyes 
  nearly 
  

   (male) 
  or 
  more 
  than 
  (female) 
  twice 
  as 
  wide 
  as 
  the 
  first 
  antennal 
  joint; 
  

   fastigium 
  steeply 
  declivent, 
  not 
  very 
  deeply 
  (male) 
  or

  and 
  very 
  

   shallowly 
  (female) 
  sulcate 
  throughout; 
  frontal 
  costa 
  failing 
  to 
  reach 
  

   the 
  clypeus, 
  slightly 
  narrower 
  than 
  the 
  interspace 
  between 
  the 
  eyes, 
  

   subequal 
  but 
  faintly 
  and 
  very 
  gradually 
  broadening 
  downward, 
  

   depressed 
  at 
  and 
  sometimes 
  sulcate 
  below 
  the 
  ocellus, 
  biseriately 
  punc- 
  

   tate; 
  eyes 
  moderately 
  prominent 
  especially 
  in 
  the 
  male, 
  not 
  veiy 
  large, 
  

   but 
  little 
  longer 
  than 
  the 
  intraocular 
  portion 
  of 
  the 
  genae; 
  antennae 
  

   ferruginous, 
  fully 
  four-fifths 
  (male) 
  or 
  from 
  three-fifths 
  to 
  two-thirds 
  

   (female) 
  as 
  long 
  as 
  the 
  hind 
  femora. 
  Pronotum 
  subecjual 
  or 
  enlarging 
  

   a 
  little 
  on 
  the 
  metazona 
  (in 
  the 
  female 
  throughout), 
  the 
  lateral 
  lobes 
  

   lighter, 
  sometimes 
  considerably 
  lighter 
  than 
  the 
  disk, 
  with 
  a 
  broad, 
  

   equal, 
  piceous, 
  postocular 
  band 
  crossing 
  the 
  prozona, 
  the 
  disk 
  often 
  

   luteo-ferruginous 
  punctate 
  with 
  fuscous, 
  very 
  broadly 
  convex, 
  and 
  

   passing 
  by 
  an 
  abrupt 
  but 
  smoothed 
  shoulder 
  simulating 
  a 
  lateral 
  carina 
  

   into 
  the 
  anteriorly 
  tumid 
  vertical 
  lateral 
  lobes: 
  median 
  carina 
  slight, 
  

   percurrent, 
  distinctly 
  feebler 
  but 
  rarely 
  subobsolete 
  on 
  the 
  prozona; 
  

   front 
  margin 
  subtruncate 
  with 
  feeblest 
  possible 
  indications 
  of 
  a 
  median 
  

   emargination, 
  hind 
  margin 
  very 
  obtusangulate, 
  the 
  angle 
  rounded 
  in
