  Of

  fuscous, 
  often 
  with

   ferruginous 
  tinge, 
  x^articularly 
  in 
  the

  Head 
  a 
  little 
  prominent, 
  

   olivaceo 
  plumbeous, 
  above 
  much 
  infuscated, 
  especially 
  in 
  a 
  pair 
  of 
  wid- 
  

   ening 
  stripes 
  behind 
  the 
  lateral 
  margins 
  of 
  the 
  fastigium, 
  and 
  with 
  a 
  

   piceous 
  j)ostocular 
  stripe; 
  interspace 
  between 
  the 
  eyes 
  distinctly 
  wider 
  

   than 
  (male) 
  or 
  fully 
  twice 
  as 
  wide 
  as 
  (female) 
  the 
  first 
  auteuual 
  joint; 
  

   fastigium 
  strongly 
  declivent, 
  considerably 
  (male) 
  or 
  shallowly 
  (female) 
  

   sulcate, 
  but 
  variable; 
  frontal 
  costa 
  just 
  failing 
  to 
  reach 
  the 
  clypeus, 
  

   subequal, 
  as 
  broad 
  as 
  the 
  interspace 
  betw^een 
  the 
  eyes, 
  sulcate 
  at 
  and 
  

   below 
  the 
  ocellus,

  j)unctate 
  above;

  moderately 
  prom- 
  

   inent 
  in

  male, 
  not 
  at 
  all 
  so 
  in 
  the 
  female, 
  much 
  longer, 
  especially 
  

   in 
  the 
  male, 
  than 
  the 
  infraocular 
  portion 
  of 
  the 
  genae; 
  antennae 
  fer- 
  

   ruginous 
  or 
  luteoferruginous, 
  often 
  a 
  little 
  infuscated 
  apically, 
  about 
  

   four-fifths 
  (male)

  (female) 
  as 
  long 
  as

   Pronotum 
  feebly 
  and 
  rather 
  regularly 
  expanding 
  posteriorly, 
  the 
  disk 
  

   faintly 
  convex 
  and 
  i)assing 
  by 
  a 
  well-rounded 
  shoulder 
  (somewhat 
  

   abruptly 
  on 
  the 
  metazona) 
  into 
  the 
  anteriorly 
  tumid 
  vertical 
  lateral 
  

   lobes, 
  the 
  disk 
  generally 
  darker 
  than 
  the 
  lower 
  portion 
  of 
  the 
  lat- 
  

   eral 
  lobes 
  (occasionally 
  by 
  a 
  darker 
  jiunctation) 
  sometimes 
  irregularly 
  

   marked 
  with 
  luteous, 
  the 
  upper 
  part 
  of 
  the 
  lateral 
  lobes 
  crossed 
  by 
  a 
  

   broad 
  piceous 
  band 
  on 
  the 
  prozona, 
  the 
  lower 
  portion 
  more 
  or 
  less 
  

   closely 
  copying 
  the 
  coloring 
  of 
  the 
  face 
  but 
  usually 
  a 
  little 
  darker; 
  

   median 
  carina 
  slight, 
  percurrent, 
  a 
  little 
  (rarely 
  much) 
  less 
  di.stinct 
  on 
  

   the 
  prozona 
  than 
  on 
  the 
  metazona; 
  front 
  margin 
  subtruncate, 
  very 
  

   faintly 
  and 
  very 
  narrowly 
  flaring, 
  at 
  least 
  in 
  the 
  male; 
  hind 
  margin 
  

   obtusangulate, 
  more 
  obtusely 
  in 
  the 
  female 
  than 
  in 
  the 
  male; 
  prozona 
  

   quadrate 
  or 
  feebly 
  longitudinal 
  (male) 
  or 
  feebly 
  transverse, 
  rarely 
  quad- 
  

   rate 
  (female), 
  slightly 
  or 
  not 
  longer 
  than 
  the 
  closely 
  but 
  shallowly 
  

   punctate 
  metazona. 
  Prosternal 
  spine 
  rather 
  large, 
  appressed 
  cjlindrical, 
  

   very 
  blunt, 
  often 
  mesially 
  constricted 
  a 
  little, 
  feebly 
  retrorse; 
  interspace 
  

   between 
  mesosternal 
  lobes 
  nearly 
  twice 
  as 
  long 
  as 
  broad 
  (male) 
  or 
  a 
  

   little 
  longer 
  than 
  broad 
  (female). 
  Tegmina 
  (Plate 
  I, 
  fig. 
  h 
  ) 
  almost 
  invari- 
  

   ably 
  surpassing, 
  sometimes 
  but 
  slightly, 
  more 
  often 
  considerably, 
  the 
  

   hind 
  femora, 
  of 
  moderate 
  breadth, 
  distinctly 
  though 
  very 
  gradually 
  

   tapering, 
  brownish 
  fuscous, 
  sometimes 
  immaculate, 
  sometimes 
  sprinkled
