  being 
  plainly 
  sinuate 
  in 
  the 
  middle 
  of 
  the 
  anterior 
  part, 
  the 
  punctures 
  

   on 
  the 
  prothorax 
  are 
  equally 
  distant, 
  but 
  more 
  shallow 
  and 
  less 
  broad 
  

   than 
  in 
  A. 
  fraudulentus, 
  and 
  the 
  scutellum 
  is 
  more 
  sharply 
  acuminate 
  

   at 
  the 
  apex 
  ; 
  the 
  elytra 
  are 
  somewhat 
  distinctly 
  costulate, 
  and 
  the 
  

   pubescence 
  is 
  slightly 
  denser 
  ; 
  the 
  valves 
  of 
  the 
  genital 
  armature 
  

   although 
  of 
  somewhat 
  the 
  same 
  shape 
  as 
  in 
  A. 
  fits 
  cuius, 
  are 
  more 
  

   robust, 
  more 
  widely 
  open 
  on 
  the 
  upper 
  side 
  from 
  base 
  to 
  apex.

  Colour, 
  shape, 
  and 
  size 
  of 
  A. 
  impurus 
  ; 
  distinguished 
  from 
  it 
  mainly 
  

   by 
  the 
  shape 
  of 
  the 
  clypeus 
  and 
  of 
  the 
  valves 
  of 
  the 
  genital 
  armature 
  ; 
  

   the 
  clypeus 
  instead 
  of 
  being 
  rounded 
  in 
  front 
  is 
  straight, 
  then 
  broadly 
  

   rounded 
  till 
  the 
  median 
  anterior 
  part 
  where 
  it 
  is 
  distinctly 
  emar- 
  

   ginate 
  ; 
  the 
  sculpture 
  of 
  the 
  head, 
  prothorax, 
  and 
  elytra 
  does 
  not 
  

   differ 
  also 
  from 
  that 
  of 
  A. 
  impurus 
  ; 
  the 
  suture 
  of 
  the 
  elytra 
  is 
  more 
  

   broadly 
  or 
  more 
  plainly 
  infuscate, 
  and 
  the 
  infuscate 
  patch 
  on 
  the 
  

   prothorax 
  is 
  conspicuous 
  ; 
  the 
  valves 
  of 
  the 
  genital 
  armature 
  instead 
  

   of 
  being 
  narrow 
  and 
  tapering 
  towards 
  the 
  apex 
  and 
  not 
  much 
  retuse, 
  

   are 
  sub-vertical 
  bi-partite 
  from 
  base 
  to 
  tip, 
  the 
  two 
  parts 
  are 
  a 
  little 
  

   more 
  broadly 
  separated 
  on 
  the 
  upper 
  than 
  on 
  the 
  under 
  side, 
  sym- 
  

   metrical, 
  parallel, 
  truncate 
  at 
  the 
  apex 
  and 
  with 
  the 
  outer 
  angles 
  

   slightly 
  spinose. 
  The 
  female 
  cannot 
  be 
  distinguished 
  from 
  that 
  of 
  

   A. 
  impurus 
  and 
  A. 
  exasperans.

  Adoretus 
  inglorius,

   Plate 
  XLL, 
  fig. 
  23. 
  

   Pale 
  testaceous, 
  with 
  the 
  head 
  infuscate 
  and 
  the 
  suture 
  of 
  the 
  

   elytra 
  slightly 
  darker 
  than 
  the 
  background 
  (? 
  immature) 
  or 
  fuscous- 
  

   brown 
  with 
  a 
  slight 
  metallic 
  tinge 
  and 
  with 
  the 
  sides 
  of 
  the 
  pro. 
  

   thorax 
  broadly 
  testaceous 
  ; 
  legs 
  testaceous 
  with 
  the 
  anterior 
  ones 
  

   slightly 
  rusty 
  red 
  ; 
  clypeus 
  broadly 
  rounded 
  laterally, 
  but 
  not 
  from 
  

   the 
  base, 
  plainly 
  emarginate 
  in 
  the 
  centre 
  of 
  the 
  anterior 
  part, 
  and 
  

  

  Adoretus 
  simulans, 
  n. 
  spec, 
  pi. 
  xliii., 
  fig. 
  32. 
  

  

  Almost 
  similar 
  to 
  A. 
  tessulatus, 
  Burm. 
  ; 
  the 
  vestiture 
  is 
  identical, 
  and 
  on 
  the 
  

   elytra 
  the 
  three 
  tessellate 
  rows 
  on 
  each 
  side 
  are 
  alike 
  ; 
  the 
  female 
  has 
  the 
  clypeus 
  

   also 
  arcuate 
  in 
  front, 
  but 
  it 
  is 
  a 
  little 
  longer 
  and 
  more 
  regularly 
  curved 
  from 
  the 
  

   base, 
  that 
  of 
  the 
  male 
  is 
  nearly 
  transverse 
  and 
  plainly 
  emarginate 
  in 
  front, 
  but 
  not 
  

   incised 
  as 
  in 
  the 
  same 
  sex 
  of 
  A. 
  tessulatus. 
  The 
  shape 
  of 
  the 
  genital 
  armature 
  is 
  

   quite 
  different 
  from 
  that 
  of 
  the 
  latter, 
  and 
  closely 
  resembles 
  that 
  of 
  A. 
  separabilis, 
  

   a 
  very 
  distinct 
  species, 
  but 
  the 
  opening 
  is 
  much 
  more 
  ovate, 
  and 
  the 
  apical 
  incision 
  

   is 
  broader, 
  deeper, 
  and 
  its 
  apical 
  angles 
  sharper.
