  Mentum 
  sub-parallel 
  or 
  trapezoidal, 
  deeply 
  incised 
  laterally 
  near 
  

   the 
  point 
  of 
  insertion 
  of 
  the 
  antennae 
  which 
  are 
  inserted 
  in 
  the 
  outer 
  

   face, 
  narrower 
  thence 
  to 
  the 
  apex, 
  the 
  anterior 
  part 
  of 
  which 
  is 
  either 
  

   nearly 
  straight 
  but 
  plainly 
  incised 
  in 
  the 
  middle, 
  or 
  slopes 
  a 
  little 
  

   on 
  each 
  side 
  from 
  the 
  broadly 
  and 
  deeply 
  incised 
  median 
  part, 
  

   convex, 
  but 
  depressed 
  in 
  the 
  anterior 
  part 
  ; 
  labial 
  palpi 
  short, 
  the 
  

   apical 
  one 
  sub-cylindrical 
  ; 
  maxillae 
  robust 
  or 
  moderately 
  robust 
  

   ending 
  at 
  the 
  tip 
  in 
  two 
  arcuate 
  teeth 
  transversally 
  set, 
  the 
  first 
  

   tooth 
  is 
  disconnected 
  from 
  the 
  second 
  and 
  is 
  more 
  slender, 
  the 
  other 
  

   one 
  is 
  either 
  bifid, 
  or 
  trifid, 
  but 
  sometimes 
  the 
  three 
  teeth 
  are 
  only 
  

   slightly 
  connate 
  at 
  the 
  base, 
  maxillary 
  palpi 
  long, 
  apical 
  joint 
  sub- 
  

   fusiform, 
  not 
  quite 
  as 
  long 
  as 
  the 
  two 
  preceding 
  taken 
  together, 
  or 
  

   only 
  a 
  little 
  longer 
  than 
  the 
  penultimate 
  one, 
  and 
  obsoletely 
  impressed 
  

   laterally 
  ; 
  labrum 
  vertical, 
  obliquely 
  attenuate 
  laterally, 
  or 
  triangular; 
  

   crenulate, 
  mandibles 
  swollen 
  at 
  the 
  base, 
  hollowed 
  inwardly, 
  curved 
  

   and 
  acute 
  at 
  the 
  tip, 
  and 
  sometimes 
  serrate 
  inwardly 
  ; 
  clypeus 
  

   declivous 
  in 
  front, 
  edged 
  with 
  a 
  fine, 
  more 
  or 
  less 
  raised 
  margin, 
  

   either 
  semicircular, 
  rounded 
  in 
  front 
  only, 
  or 
  occasionally 
  sub- 
  

   truncate, 
  or 
  sub-truncate 
  but 
  emarginate 
  in 
  the 
  middle, 
  shorter 
  and 
  

   separated 
  from 
  the 
  head 
  by 
  a 
  transverse 
  impressed 
  line, 
  head 
  and 
  

   clypeus 
  plainly 
  scabrose 
  ; 
  eyes 
  very 
  large, 
  bulging, 
  divided 
  above 
  

   the 
  median 
  part 
  by 
  the 
  canthus 
  of 
  the 
  genae 
  for 
  a 
  third 
  of 
  the 
  

   length 
  ; 
  antennae 
  short, 
  slender, 
  ten-jointed, 
  club 
  as 
  long 
  as 
  the 
  

   five 
  preceding 
  joints 
  taken 
  together 
  ; 
  prothorax 
  twice 
  as 
  broad 
  as 
  

   long, 
  very 
  little 
  sinuate 
  in 
  front, 
  but 
  more 
  distinctly 
  so 
  along 
  the 
  

   base 
  the 
  angles 
  of 
  which 
  are 
  somewhat 
  rounded, 
  sides 
  also 
  rounded 
  

   in 
  the 
  middle 
  and 
  fringed 
  there 
  with 
  bristly 
  hairs 
  ; 
  scutellum 
  as 
  long 
  

   as 
  broad 
  at 
  the 
  base, 
  ogival, 
  but 
  not 
  very 
  sharply 
  acuminate 
  ; 
  elytra 
  

   hardly 
  wider 
  at 
  the 
  base 
  than 
  that 
  of 
  the 
  prothorax, 
  slightly 
  ampliate 
  

   thence 
  for 
  about 
  one-sixth 
  of 
  the 
  length, 
  then 
  sinuate, 
  and 
  a 
  little 
  

   more 
  ampliated 
  from 
  there 
  to 
  the 
  rounded 
  apical 
  part, 
  they 
  have 
  on 
  

   each 
  side 
  a 
  distinct 
  stria 
  along 
  the 
  suture 
  and 
  usually 
  four, 
  more 
  or 
  

   less 
  raised, 
  costules 
  usually 
  with 
  a 
  somewhat 
  regular 
  series 
  of 
  

   punctures 
  on 
  each 
  side 
  of 
  them 
  ; 
  the 
  propygidium 
  is 
  partly 
  hidden 
  by 
  

   the 
  elytra, 
  the 
  propygidium 
  is 
  somewhat 
  convex 
  in 
  the 
  middle, 
  and 
  

   vertical 
  ; 
  anterior 
  tibiae 
  tri-dentate 
  outwardly, 
  basal 
  tooth 
  very 
  short, 
  

   inner 
  spur 
  long 
  and 
  slender 
  ; 
  intermediate 
  and 
  posterior 
  tibiae 
  with 
  

   two 
  transverse 
  rows 
  of 
  bristles 
  not 
  always 
  very 
  distinct 
  on 
  the 
  outer
