  Pronotum 
  subequal, 
  tbe 
  

   metazona 
  expanding 
  somewhat, 
  the 
  disk 
  of 
  the 
  prozona 
  sometimes 
  (but 
  

   not 
  always) 
  very 
  feebly 
  tumid, 
  the 
  front 
  margin 
  feeblj' 
  convex, 
  thehiud 
  

   margin 
  obtusely 
  and 
  roundly 
  angulate, 
  more 
  obtusely 
  in 
  specimens 
  

   from 
  the 
  Pacific 
  Coast 
  than 
  in 
  others, 
  the 
  median 
  carina 
  distinct 
  and 
  

   sharp 
  on 
  the 
  metazona, 
  less 
  prominent 
  but 
  distinct 
  on 
  the 
  anterior 
  half 
  

   of 
  the 
  prozona, 
  still 
  less 
  distinct 
  (occasionally 
  subobsolete) 
  between 
  the 
  

   sulci; 
  prozona 
  subcpiadrate 
  in 
  both 
  sexes, 
  smooth, 
  divided 
  in 
  the 
  mid- 
  

   dle, 
  and 
  barely 
  before 
  the 
  middle 
  of 
  the 
  posterior 
  half, 
  by 
  sulci, 
  the 
  

   principal 
  sulcus 
  bent 
  forward 
  in 
  the 
  middle 
  by

   tion 
  of 
  the 
  prozona, 
  the 
  metazona 
  plane, 
  tinely 
  subruguloso 
  punctate; 
  

   lateral 
  lobes 
  nearly 
  vertical, 
  separated 
  from 
  the 
  disk 
  by 
  a 
  well 
  rounded 
  

   angle 
  nowhere 
  forming 
  distinct 
  lateral 
  carinae, 
  marked 
  next 
  the 
  upper 
  

   limit 
  on 
  the 
  prozona 
  by 
  broken 
  blackish 
  patches, 
  frequently 
  reduced 
  

   to 
  a 
  pair 
  of 
  short, 
  oblique, 
  black 
  dashes, 
  one 
  in 
  either 
  longitudinal 
  half 
  

   of 
  the 
  prozona, 
  each 
  in 
  a 
  clearer 
  field, 
  and 
  also 
  by 
  the 
  blackening 
  of 
  the 
  

   sulci 
  in 
  this 
  region 
  ; 
  they 
  are 
  sometimes 
  accompanied 
  by 
  slender, 
  

   oblique, 
  parallel, 
  black 
  lines 
  lower 
  down, 
  the 
  hinder
