   regularly 
  and 
  deeply 
  punctured,

  greyish 
  hairs 
  less 
  dense 
  

   but 
  longer

  from 
  each

  springs 
  a 
  very 
  

   short, 
  sub-erect 
  hair, 
  and 
  each 
  one 
  has 
  two 
  rounded, 
  not 
  very 
  con- 
  

   spicuous 
  costae 
  which 
  are 
  more 
  deeply 
  but 
  not 
  as 
  closely 
  punctured 
  

   as 
  the 
  intervals, 
  or 
  the 
  sides

  hind 
  tibiae 
  red, 
  robust,

  The 
  only 
  male 
  I 
  have 
  seen 
  had 
  lost 
  its 
  hind 
  tibiae, 
  and 
  I 
  have 
  

   therefore 
  to 
  cull 
  the 
  description 
  of 
  that 
  part 
  from 
  Burmeister 
  ; 
  

   unfortunately 
  it 
  is 
  not 
  as 
  clear 
  as 
  it 
  might 
  be.

  Male 
  : 
  Black, 
  or 
  very 
  dark 
  fuscous 
  brown 
  ;

  with 
  three 
  

   bands 
  of 
  whitish 
  or 
  sub-flavescent 
  scales 
  ; 
  scutellum 
  and 
  elytra 
  

   sprinkled 
  with 
  similar 
  scales 
  which 
  also 
  edge 
  the 
  abdominal 
  segments 
  

   and 
  the 
  metasternum 
  ; 
  head 
  very 
  rugose, 
  clypeus 
  parallel, 
  slightly 
  

   arcuate 
  at 
  tip, 
  and 
  with 
  the 
  outer 
  angles 
  not 
  much 
  rounded, 
  

   apical 
  margin 
  renexed; 
  prothorax 
  scarcely 
  pubescent 
  but 
  having 
  

   some 
  stiff, 
  long 
  bristles 
  along 
  the 
  anterior 
  and 
  lateral 
  margins, 
  very 
  

   conspicuously 
  grooved 
  longitudinally 
  in 
  the 
  middle, 
  the 
  groove 
  

   usually 
  filled 
  with 
  scales, 
  very 
  diagonally 
  attenuate 
  laterally 
  in 
  the 
  

   anterior 
  part 
  and 
  distinctly 
  emarginate 
  in 
  the 
  posterior 
  where 
  the 
  

   basal 
  angle 
  is 
  sharp, 
  it 
  is 
  very 
  closely 
  scabroso-punctate 
  ; 
  the 
  scu- 
  

   tellum 
  is 
  partly 
  covered 
  with 
  elongate 
  scales, 
  and 
  those 
  on 
  the 
  

   elytra 
  are 
  somewhat 
  scattered, 
  but 
  are 
  still 
  somewhat 
  seriate 
  ; 
  the 
  

   propygidium 
  and 
  pygidium 
  are 
  without 
  scales 
  and 
  nearly 
  glabrous 
  ; 
  

   the 
  hind 
  femora 
  are 
  greatly 
  developed, 
  the 
  trochanters 
  are 
  sharply 
  

   spinose, 
  and 
  the 
  femora 
  have 
  an 
  apical, 
  distinct 
  tooth 
  under 
  the 
  

   articulation 
  of 
  the 
  knee 
  ; 
  the 
  hind 
  tibiae 
  have 
  inwardly 
  a 
  broad 
  but
