  Pale 
  testaceous 
  (alcoholic 
  specimens). 
  Head 
  not 
  prominent, 
  uniform 
  

   in 
  coloring 
  excei)tfor 
  a 
  sometimes 
  obsolete 
  median 
  black 
  stripe 
  on 
  sum- 
  

   mit, 
  and 
  a 
  broad 
  postocular 
  piceous 
  baud; 
  vertex 
  feebly 
  tumid, 
  not 
  or 
  

   sliii'litly 
  elevated 
  above 
  the 
  i)ronotum, 
  the 
  interspace 
  between 
  the 
  eyes 
  

   half 
  as 
  broad 
  again 
  (male), 
  or 
  nearly 
  twice 
  as 
  broad 
  (female) 
  as 
  the 
  lirst 
  

   antennal 
  joint; 
  fastigium 
  steeply 
  declivent, 
  sulcate 
  throughout, 
  more 
  

   broadly 
  in 
  the 
  female 
  than 
  in 
  the 
  male; 
  frontal 
  costa 
  percurrent, 
  rather 
  

   prominent 
  above 
  but 
  shallow 
  below, 
  equal 
  except 
  for 
  a 
  sudden 
  and 
  

   slight 
  contraction 
  between 
  the 
  antennae,' 
  fully 
  as 
  broad 
  as 
  the 
  inter- 
  

   space 
  between 
  the 
  eyes, 
  faintly 
  sulcate 
  at 
  and 
  below 
  the 
  ocellus, 
  finely 
  

   and 
  faintly 
  punctate 
  throughout; 
  eyes 
  of 
  medium 
  size 
  and 
  prominence, 
  

   longer, 
  in 
  the 
  male 
  much 
  longer, 
  than 
  the 
  intraocular 
  portion 
  of 
  the 
  

   genae; 
  antennae 
  testaceous, 
  nearly 
  two-thirds 
  (male) 
  or 
  one-half 
  (female) 
  

   as 
  long 
  as 
  the 
  hind 
  femora. 
  Pronotum 
  compressed, 
  unusually 
  equal, 
  

   scarcely 
  or 
  not 
  expanding 
  on 
  the 
  metazona, 
  the 
  disk 
  very 
  uniform, 
  

   broadly 
  convex, 
  passing 
  by 
  a 
  rounded 
  angle 
  into 
  the 
  interiorly 
  vertical 
  

   faintly 
  tumid 
  lateral 
  lobes 
  without 
  forming 
  lateral 
  carinae; 
  a 
  broad 
  

   piceous 
  belt, 
  sometimes 
  obscured, 
  occupies 
  the 
  upper 
  half 
  of 
  the 
  lateral 
  

   lobes 
  of 
  theprozona; 
  median 
  carina 
  distinct, 
  percurrent, 
  equal 
  ; 
  front 
  

   margin 
  subtruncate, 
  hind 
  margin 
  very 
  obtusaugulate; 
  prozona 
  dis- 
  

   tinctly 
  (male) 
  or 
  feebly 
  (female) 
  longitudinal, 
  about 
  a 
  fourth 
  longer 
  

   than 
  the 
  finely' 
  punctate 
  metazona, 
  which 
  encroaches 
  upon 
  it 
  mesially 
  

   by 
  the 
  angularity 
  of 
  the 
  principal 
  sulcus. 
  Prosternal 
  spine 
  rather 
  

   long, 
  appressed 
  conical, 
  a 
  little 
  retrorse, 
  bluntly 
  pointed; 
  interspace 
  

   between 
  mesosternal 
  lobes 
  subequal, 
  a 
  little 
  longer 
  than 
  broad 
  (male) 
  

   or 
  transverse 
  but 
  narrower 
  than 
  the 
  lobes 
  (female).

  abbre- 
  

   Anate, 
  ovate-lanceolate, 
  overlapping, 
  from 
  a 
  little 
  longer 
  than

  pro- 
  

   notum 
  to 
  a 
  third 
  as 
  long 
  again, 
  apically 
  rather 
  abruptly 
  acuminate, 
  

   brownish-testaceous, 
  sometimes 
  with 
  feeble 
  signs 
  of 
  a 
  slender 
  line 
  of 
  

   maculations.

  the 
  male 
  a 
  little

  hind 
  

   femora 
  slender, 
  testaceous 
  (apparently 
  olivaceo-testaceous), 
  sometimes 
  

   bi 
  maculate 
  with 
  fuscous 
  on 
  the 
  inner 
  lialf 
  of 
  the 
  upper 
  face, 
  with 
  black 
  

   genicular 
  arc; 
  hind 
  tibiae 
  pale 
  red 
  (?), 
  apically 
  infuscated, 
  the 
  si)ines 
  

   pallid 
  at

  black 
  beyond, 
  ten

  sloping 
  in 
  a 
  concave

  to 
  the 
  summit 
  of 
  

   the 
  very 
  sharp 
  and 
  rather

  inclosing 
  the
