  Mentum 
  ovate 
  laterally 
  from 
  the 
  base 
  to 
  two-thirds 
  of 
  the 
  length, 
  

   constricted 
  near 
  the 
  point 
  of 
  insertion 
  of 
  the 
  palpi, 
  thence 
  sub- 
  

   obliquely 
  ampliated 
  towards 
  the 
  apical 
  part, 
  which 
  is 
  broadly 
  but 
  

   not 
  deeply 
  emarginate, 
  and 
  fringed 
  with 
  dense 
  somewhat 
  bristly 
  

   hairs, 
  the 
  outer 
  face 
  is 
  deeply 
  and 
  broadly 
  foveate,

  very 
  long 
  

   and 
  very 
  stiff 
  black 
  bristles, 
  it 
  is 
  impressed 
  in 
  the 
  anterior 
  part 
  and 
  

   convex 
  thence 
  towards 
  the 
  base 
  ; 
  the 
  maxillae 
  are 
  long, 
  robust, 
  the 
  

   upper 
  lobe 
  is 
  produced 
  into 
  three 
  long, 
  sharply 
  falcate 
  teeth

  each 
  

   side,

  has 
  a 
  pencil 
  of 
  long 
  hairs 
  at 
  the 
  tip, 
  the 
  last 
  joint 
  of 
  the 
  

   palpi 
  is 
  fusiform, 
  slightly 
  truncate 
  at 
  the 
  tip 
  ; 
  the 
  mandibles 
  are 
  

   long, 
  flat, 
  truncate 
  at 
  the 
  tip, 
  very 
  densely 
  ciliate 
  inwardly, 
  and 
  

   project 
  slightly 
  beyond 
  the 
  labrum 
  which 
  is 
  horizontal, 
  a 
  little 
  

   shorter 
  than 
  the 
  clypeus, 
  transverse, 
  a 
  little 
  attenuated 
  towards 
  the 
  

   apex, 
  where 
  it 
  is 
  slightly 
  emarginate 
  ; 
  clypeus 
  a 
  little 
  more 
  than 
  

   twice 
  as 
  broad 
  as 
  long, 
  straight 
  in 
  front, 
  slightly 
  rounded 
  laterally, 
  

   head 
  twice 
  as 
  long 
  as 
  broad 
  not 
  separated 
  from 
  the 
  clypeus 
  by 
  a 
  

   suture, 
  eyes 
  moderately 
  large, 
  not 
  quite 
  evenly 
  divided 
  by 
  the 
  

   canthus 
  of 
  the 
  genae 
  ; 
  antennae 
  short, 
  nine-jointed, 
  club 
  as 
  long 
  as 
  all 
  

   the 
  other 
  joints 
  taken 
  together 
  ; 
  prothorax 
  narrowly 
  marginate 
  all 
  

   round, 
  longer 
  than 
  broad, 
  very 
  little 
  sinuate 
  in 
  front, 
  rounded 
  

   laterally 
  and 
  also 
  ampliate 
  in 
  the 
  anterior 
  part, 
  and 
  deeply 
  emarginate 
  

   from 
  about 
  one-third 
  of 
  the 
  length 
  to 
  the 
  basal 
  angle 
  which 
  is 
  

   slightly 
  rounded, 
  basal 
  part 
  obliquely 
  prolonged 
  towards 
  the 
  

   scutellum, 
  but 
  not 
  angular 
  in 
  the 
  centre, 
  and 
  narrower 
  than 
  the 
  

   elytra 
  ; 
  scutellum 
  broad 
  at 
  the 
  base, 
  thence 
  narrowed, 
  long, 
  sharply 
  

   acuminate 
  at 
  the 
  tip 
  ; 
  elytra 
  as 
  broad 
  as 
  long, 
  but 
  short 
  and 
  barely 
  

   reaching 
  the 
  propygidium 
  which 
  is 
  very 
  broad, 
  plane 
  on 
  the 
  disk, 
  but 
  

   with 
  a 
  conspicuous 
  basal 
  humeral 
  callus, 
  and 
  a 
  deep 
  impression 
  

   between 
  it 
  and 
  the 
  outer 
  margin 
  which 
  is 
  somewhat 
  rounded 
  

   laterally 
  and 
  more 
  ampliated 
  above 
  the 
  mesothoracic 
  epimera 
  ; 
  the 
  

   latter 
  are 
  greatly 
  developed, 
  but 
  do 
  not 
  project 
  much 
  beyond 
  the 
  

   outer 
  margin 
  ;

  convex 
  in 
  the 
  

   apical 
  part 
  ; 
  abdomen 
  compressed 
  laterally, 
  the 
  first 
  five 
  basal 
  

   segments 
  fused, 
  penultimate 
  one 
  as 
  broad 
  as

  four 
  preceding 
  and 
  

   a 
  little 
  broader 
  than 
  the 
  apical 
  one 
  ; 
  metasternum 
  moderately 
  broad, 
  

   mesosternum 
  very 
  small 
  ; 
  legs 
  moderately 
  long, 
  posterior 
  femora 
  and 
  

   tibiae 
  robust, 
  somewhat 
  short, 
  the 
  intermediate 
  and 
  posterior 
  tibiae 
  

   with 
  two 
  conspicuous 
  apical 
  spurs 
  and 
  with 
  transverse 
  ciliate 
  rows
