  slightly

  steeply 
  declivent, 
  

   sulcate, 
  narrow, 
  considerably

  moderate, 
  nearly 
  equal,

   slightly

  long 
  as

  or 
  dis- 
  

   tinctly 
  longer 
  than 
  (male) 
  the 
  intraocular 
  portion 
  of 
  the 
  genae; 
  

   antennae 
  flavo-testaceous, 
  about 
  five-sixths

  the 
  prozona 
  slightly 
  swollen

   broad 
  black

  at 
  the 
  upper 
  limit 
  of

  lobes 
  of

  edge 
  the 
  

   lower 
  side 
  of 
  the 
  position 
  of 
  the 
  lateral 
  carinae, 
  or, 
  if 
  of 
  equal 
  width 
  

   with 
  the 
  preceding 
  portion, 
  is 
  enlivened

  continuation 
  of 
  the 
  black 
  bordered 
  

   yellowish 
  stripe 
  on 
  the 
  metathoracic 
  epipleura; 
  occasionally 
  the 
  band 
  

   is 
  wholly 
  obsolete

  the 
  metazona 
  ; 
  in

  portion 
  of 
  

   the 
  band 
  on 
  the 
  prozona 
  is 
  also

  roundish 
  or 
  oblique 
  pyriform

  (male) 
  or 
  very 
  feebly 
  (female) 
  

   longitudinal, 
  a 
  third 
  (male) 
  or 
  a 
  fourth 
  (female) 
  longer 
  than 
  the 
  finely 
  

   and 
  clearly 
  punctate 
  metazona. 
  Prosternal 
  spine 
  not 
  very 
  long, 
  

   conical, 
  blunt 
  tipped, 
  suberect; 
  interspace 
  between 
  mesosternal 
  lobes 
  

   fully 
  (male) 
  or 
  nearly 
  (female) 
  half 
  as 
  long 
  again 
  as 
  broad.

  ovate, 
  about 
  twice 
  as

  about 
  equally

  brownish 
  fuscous, 
  

   clouded

  gently 
  tumid 
  

   in 
  the

  dull
