  fuscous 
  with 
  a 
  distinct 
  and 
  

   broad

  band;

  gently 
  convex, 
  scarcely 
  elevated 
  

   above

  half 
  as 
  broad

  contracted 
  narrowly 
  at

  slightly 
  narrower 
  than

  interspace 
  between 
  

   the 
  eyes, 
  fading 
  just 
  before 
  the 
  clypeus, 
  feebly 
  sulcate

  moderate 
  size, 
  rather 
  promi- 
  

   nent,

  dark 
  castaneous,

  infuscated,

  upper 
  portion 
  of 
  the 
  lateral 
  

   lobes 
  occupied 
  by 
  a 
  broad 
  piceous 
  postocular 
  band, 
  broadening 
  pos- 
  

   teriorly 
  and 
  generally 
  weaker 
  on, 
  but 
  never 
  absent 
  from, 
  the 
  metazoua; 
  

   disk 
  broadlj^ 
  convex, 
  passing 
  by 
  a 
  broadly 
  rounded 
  shoulder 
  nowhere 
  

   forming 
  semblance 
  of 
  lateral 
  carinae 
  into 
  the 
  interiorly 
  vertical 
  lateral 
  

   lobes; 
  median 
  carina 
  distinct

  margin 
  truncate 
  or 
  subtrun- 
  

   cate,

  broadly 
  convex, 
  occasionally 
  subangulate, 
  the 
  

   angle 
  exceedingly 
  obtuse; 
  prozona 
  slightly 
  longitudinal 
  (male) 
  or 
  

   quadrate 
  (female), 
  about 
  a 
  fourth 
  (male) 
  or 
  a 
  fifth 
  (female) 
  as 
  long
