  elevated, 
  well 
  arched; 
  inter- 
  

   space

   antennae, 
  the 
  fastigium 
  faintly 
  subspatulate, 
  pretty 
  deep, 
  with 
  abrni)t 
  

   but

  rounded 
  walls;

  costa 
  narrower 
  than 
  the 
  interspace 
  

   between 
  the 
  eyes, 
  slightly 
  contracted 
  above 
  and 
  very 
  slightly 
  ju>t 
  

   below 
  the 
  ocellus; 
  otherwise 
  scarcely 
  enlarging 
  from 
  above 
  downward, 
  

   scarcely 
  depressed 
  above 
  the 
  ocellus, 
  strongly 
  sulcate 
  at 
  and 
  below 
  the 
  

   same; 
  eyes 
  neither 
  large 
  nor 
  very 
  prominent;

  as

  femora.

  tumid 
  laterally, 
  and 
  as

  feebly 
  sinuate, 
  hind

  roundly 
  obtusangulate;

   equal; 
  transverse 
  sulci 
  of 
  the 
  prozona 
  pretty 
  distinct, 
  the

  median 
  carina; 
  metazona 
  scarcely 
  punctate 
  ;

  sub- 
  

   quadrate, 
  slightly 
  longer 
  than 
  the 
  metazona, 
  or,

  subequal.

  subquadrate, 
  a 
  little 
  longer 
  than 
  broad 
  (male) 
  or 
  transverse 
  

   (female). 
  Tegmina 
  reaching 
  (female) 
  or 
  slightly 
  surpassing 
  (male) 
  the 
  

   tip 
  of 
  the 
  hind 
  femora, 
  not 
  very 
  slender, 
  subequal.

   but 
  little, 
  the 
  extremity 
  broadly 
  rounded 
  ;
