  by 
  luteous; 
  vertex 
  rather 
  tumid, 
  coDsiderably 
  elevated 
  above 
  the 
  pro- 
  

   uotum, 
  the 
  interspace 
  between 
  the 
  eyes 
  fully 
  as 
  broad 
  as 
  (male) 
  or 
  

   considerably 
  broader 
  than 
  (female) 
  the 
  first 
  antennal 
  joint; 
  fastigiura 
  

   steeply 
  declivent, 
  rather 
  shallowly 
  sulcate 
  even 
  in 
  the 
  male; 
  frontal 
  

   costa 
  hardly 
  reaching 
  the 
  clypeus, 
  slightly 
  narrowed 
  above 
  to 
  meet 
  

   the 
  fastigium, 
  otherwise 
  subequal, 
  broad, 
  slightly 
  broader 
  than 
  the 
  

   interspace 
  between 
  the 
  eyes, 
  feebly 
  sulcate 
  or 
  depressed 
  at 
  the 
  ocellus, 
  

   punctate,

  at 
  the 
  sides 
  above; 
  eyes 
  moderately 
  large, 
  not

   antennae 
  luteous, 
  apically 
  becoming 
  slightly 
  ferruginous 
  or 
  fuscous, 
  

   more 
  than 
  two-thirds 
  (male) 
  or 
  about 
  three-fifths 
  (female) 
  as 
  long 
  as 
  

   the 
  hind 
  femora. 
  Pronotum

  feebly 
  flaring 
  anteriorly 
  to 
  receive 
  

   the 
  head, 
  somewhat 
  enlarging 
  posteriorly, 
  the 
  disk 
  passing 
  by 
  a 
  blunt 
  

   angle 
  into 
  the 
  lateral 
  lobes, 
  the 
  former 
  brownish 
  fuscous, 
  more 
  or 
  less 
  

   distinctly 
  ferruginous, 
  the 
  latter 
  passing 
  from 
  luteo-testaceous 
  below 
  

   to 
  fuscous 
  above, 
  the 
  prozona 
  with 
  a 
  broad 
  piceous 
  band 
  which 
  is 
  

   obliquely 
  cut 
  by 
  a 
  distinct, 
  posteriorly 
  narrowing, 
  sometimes 
  feebly 
  

   arcuate, 
  luteous 
  stripe, 
  which 
  connects 
  with 
  the 
  luteous 
  field 
  just 
  below 
  

   the 
  i)ostocular 
  band 
  of 
  the 
  head, 
  a 
  feature 
  more 
  prominent 
  in 
  the 
  female 
  

   than 
  in 
  the 
  male; 
  median 
  carina 
  percurrent, 
  often 
  black, 
  hardly 
  less 
  

   distinct 
  on 
  the 
  prozona 
  than 
  on 
  the 
  metazona;

  margin 
  feebly 
  

   convex, 
  often 
  with 
  a 
  slight 
  median

  obtus- 
  

   angulate, 
  often 
  nearly 
  rectangulate;

  slightly 
  longitudinal 
  

   (male) 
  or 
  quadrate 
  (female), 
  distinctly 
  (male) 
  or 
  hardly 
  (female) 
  longer 
  

   than 
  the 
  closely 
  punctate 
  metazona, 
  Prosternal 
  spiue 
  moderately 
  

   long, 
  cylindrical, 
  feebly 
  appressed,

  or 
  short, 
  conical, 
  

   appressed, 
  blunt 
  (female), 
  erect; 
  interspace 
  between 
  mesosternal 
  lobes 
  

   more 
  than 
  twice 
  (male) 
  or 
  only 
  a 
  little 
  (female) 
  longer 
  than 
  broad.
