  with 
  an

  tinge. 
  

   Head 
  somewhat 
  prominent, 
  olivaceo-testaceous 
  variably 
  but 
  generally 
  

   considerably 
  infuscated, 
  above 
  dark 
  fuscous, 
  separated 
  by 
  a 
  testaceous 
  

   stripe 
  from 
  the 
  broad 
  piceous 
  postocular 
  band; 
  vertex 
  gently 
  tumid, 
  

   feebly 
  elevated 
  above 
  the 
  pronotum, 
  the 
  interspace 
  between 
  the 
  eyes 
  

   half 
  as 
  broad 
  again 
  (male) 
  or 
  twice 
  as 
  broad 
  (female) 
  as 
  the 
  first 
  antenual 
  

   joint; 
  fastigium 
  somewhat 
  steeply 
  declivent, 
  plane, 
  with 
  the 
  lateral 
  

   margins 
  faintly 
  raised 
  in 
  the 
  male; 
  frontal 
  costa 
  fading 
  before 
  the 
  clyp- 
  

   eus, 
  equal 
  or 
  subequal, 
  as 
  wide 
  as 
  the 
  interspace 
  between 
  the 
  eyes, 
  

   sulcate 
  at 
  and 
  below 
  the 
  ocellus, 
  at 
  least 
  in 
  the 
  male, 
  somewhat 
  densely 
  

   punctate 
  throughout; 
  eyes 
  moderately 
  large 
  and 
  prominent, 
  very 
  much 
  

   longer 
  than 
  the 
  infraocular 
  portion 
  of 
  the 
  genae; 
  antennae 
  rufo-testa- 
  

   ceous, 
  scarcely 
  shorter 
  than

  nearly 
  two-thirds 
  as 
  long 
  as

  the 
  hind 
  femora. 
  Pronotum 
  subequal, 
  feebly 
  enlarging 
  (at 
  least 
  

   below)

  the 
  metazona, 
  the 
  sides 
  with 
  a 
  broad 
  piceons 
  postocular 
  band 
  

   confined 
  to 
  the 
  prozona 
  in 
  the 
  male, 
  the 
  same 
  being 
  wholly 
  obsolete, 
  

   obscure, 
  or 
  confined 
  to 
  the 
  upper 
  limits 
  of 
  the 
  lateral 
  lobes 
  in 
  the 
  female; 
  

   disk 
  very 
  broadly 
  convex, 
  passing 
  by 
  a 
  distinct 
  but 
  blunt 
  angulation 
  

   forming 
  feeble 
  lateral 
  carinae 
  into 
  the 
  interiorly 
  vertical 
  lateral 
  lobes; 
  

   median 
  carina 
  distinct 
  but 
  not 
  very 
  sharp 
  on 
  the 
  metazona, 
  subobso- 
  

   lete 
  or 
  obsolete, 
  especially 
  between 
  the 
  sulci 
  and, 
  in 
  the 
  male, 
  on 
  the 
  

   prozona; 
  front 
  margin 
  truncate,
