  Head 
  and 
  prothorax 
  bronze-green, 
  moderately 
  shining, 
  under 
  side 
  

   and 
  legs 
  metallic 
  black, 
  antennae 
  black 
  ; 
  scutellum 
  bottle-green, 
  elytra 
  

   pale 
  testaceous 
  with 
  the 
  suture 
  and 
  outer 
  margin 
  narrowly 
  edged 
  

   with 
  fuscous 
  bronze, 
  and 
  having 
  in 
  the 
  posterior 
  part 
  either 
  a 
  very 
  

   broad 
  bronze 
  black 
  band 
  reaching 
  to 
  the 
  apex 
  and 
  emitting 
  two 
  or 
  

   three 
  longitudinal 
  bands 
  reaching 
  to 
  about 
  the 
  median 
  part, 
  or 
  

   having 
  only 
  these 
  three 
  bands 
  and 
  no 
  transverse 
  patch 
  ; 
  the 
  upper 
  

   side 
  is 
  glabrous, 
  but 
  the 
  upper 
  half 
  of 
  the 
  pygidium 
  is 
  clothed 
  with 
  

   dense 
  appressed 
  greyish 
  white 
  hairs, 
  and 
  the 
  abdominal 
  segments 
  

   and 
  also 
  the 
  pectus 
  are 
  sparingly 
  pubescent 
  ; 
  clypeus 
  a 
  little 
  broader 
  

   than 
  long, 
  obtuse 
  in 
  front 
  and 
  with 
  the 
  angles 
  very 
  broadly 
  rounded 
  

   and 
  the 
  margins 
  strongly 
  reflexed, 
  it 
  is 
  darker 
  than 
  the 
  head 
  and 
  very 
  

   closely 
  shagreened 
  like 
  the 
  latter, 
  but 
  the 
  granules 
  are 
  smaller 
  

   still 
  ; 
  prothorax 
  somewhat 
  convex 
  and 
  not 
  marginate 
  along 
  the 
  base 
  ; 
  

   covered 
  with 
  deep, 
  round 
  punctures 
  very 
  closely 
  set 
  ; 
  scutellum 
  as 
  

   wide 
  as 
  long, 
  broadly 
  ogival, 
  rounded 
  at 
  the 
  tip, 
  and 
  deeply 
  and 
  

   closely 
  punctured 
  ; 
  elytra 
  as 
  broad 
  as 
  long, 
  distinctly 
  sinuate 
  laterally 
  

   at 
  about 
  one-fourth 
  of 
  the 
  length, 
  broader 
  from 
  there 
  and 
  only 
  very 
  

   slightly 
  ampliate 
  in 
  the 
  median 
  part, 
  plane 
  with 
  the 
  humeral 
  callus 
  

   only 
  conspicuous, 
  not 
  very 
  deeply 
  punctato-striate 
  on 
  the 
  dorsal 
  

   part, 
  but 
  more 
  so 
  on 
  the 
  sides, 
  and 
  with 
  the 
  intervals 
  plane 
  on 
  the 
  

   dorsal 
  part, 
  but 
  somewhat 
  costulate 
  laterally 
  ; 
  legs 
  somewhat 
  deeply 
  

   punctured 
  outwardly, 
  femora 
  sparingly 
  pubescent 
  ; 
  tarsi 
  piceous. 
  

  

  The 
  shape 
  and 
  size 
  of 
  the 
  posterior 
  black 
  transverse 
  patch 
  on 
  the 
  

   elytra 
  varies 
  in 
  almost 
  every 
  example 
  which 
  I 
  have 
  seen 
  ; 
  it 
  even 
  

   disappears 
  altogether, 
  leaving 
  only 
  a 
  faint 
  trace 
  of 
  two 
  longitudinal 
  

   slightly 
  infuscate 
  lines.

  Mentum 
  quadrangular 
  from 
  the 
  base 
  to 
  about 
  the 
  median 
  part, 
  

   incised 
  laterally 
  there 
  and 
  slightly 
  narrower 
  thence 
  to 
  the 
  apex, 
  

   which 
  is 
  very 
  deeply 
  scooped 
  in 
  the 
  shape 
  of 
  a 
  crescent, 
  and 
  edged 
  

   with 
  stiff 
  bristles 
  ; 
  the 
  palpi 
  are 
  like 
  those 
  of 
  Pojnllia, 
  but

  apical
