  head 
  

   and 
  prothorax 
  clothed 
  with 
  dense, 
  villose 
  fulvous 
  hairs 
  ; 
  clypeus 
  

   parallel 
  but 
  with 
  the 
  outer 
  angles 
  slightly 
  rounded, 
  and 
  the 
  apical

   is 
  denuded

  but 
  the

  are 
  very 
  deeply 
  punctured,

  impressed 
  longi- 
  

   tudinally 
  close 
  to

  humeral 
  callus, 
  and 
  having 
  a 
  few

  but 
  

   broad 
  punctures 
  scattered 
  on 
  the 
  discoidal 
  part 
  ; 
  pygidium 
  vertical, 
  

   smooth 
  in 
  the 
  centre, 
  punctate 
  laterally, 
  fringed 
  with 
  villose 
  greyish 
  

   hairs, 
  not 
  scaly 
  ; 
  hind 
  legs 
  and 
  pectus 
  clothed 
  with 
  a 
  long 
  greyish- 
  

   white 
  pubescence 
  ; 
  hind 
  femora 
  very 
  thick, 
  and 
  having 
  a 
  short 
  but 
  

   sharp 
  spine 
  close 
  to 
  the 
  knee 
  but 
  on 
  the 
  outer 
  side, 
  and 
  the 
  trochanter 
  

   is 
  produced 
  into 
  a 
  very 
  long, 
  slender 
  spine 
  ; 
  the 
  tibiae 
  are 
  somewhat 
  

   compressed, 
  not 
  deeply 
  grooved 
  beneath 
  but 
  have 
  a 
  somewhat 
  

   blunt 
  tooth 
  at 
  the 
  basal 
  inner 
  part 
  of 
  the 
  groove, 
  and 
  a 
  sharp, 
  

   horizontal 
  inner 
  spine 
  at 
  a 
  short 
  distance 
  from 
  the 
  apex, 
  where 
  there 
  

   is 
  a 
  short 
  but 
  very 
  distinct 
  apical 
  spur, 
  the 
  walls 
  of 
  the 
  groove 
  are 
  

   bluntly 
  serrate, 
  and 
  the 
  inner 
  part 
  of 
  the 
  tibiae 
  are 
  very 
  densely 
  

   villose 
  ; 
  only 
  the 
  claws 
  of 
  the 
  hind 
  legs 
  are 
  simple, 
  the 
  others 
  are 
  

   double 
  and 
  slightly 
  cleft. 
  

  

  Female 
  : 
  Like 
  the 
  male 
  in 
  all 
  respects, 
  except 
  that 
  the 
  hind 
  claw 
  

   is 
  simple, 
  but 
  distinctly 
  cleft.

  Monochelus 
  geatus, 
  n. 
  spec. 
  

  

  Black, 
  with 
  the 
  elytra 
  red, 
  very 
  shining, 
  and 
  with 
  the 
  head 
  and 
  

   prothorax, 
  the 
  scutellum, 
  the 
  under 
  side 
  and 
  legs, 
  clothed 
  with 
  very 
  

   long, 
  villose 
  fulvous 
  hairs, 
  there 
  are 
  very 
  few 
  scales 
  along 
  the 
  outer 
  

   margins 
  of 
  the 
  prothorax, 
  and 
  there 
  is 
  a 
  small 
  juxta-sutural 
  patch 
  of 
  

   yellowish 
  scales 
  on 
  each 
  side 
  of 
  the 
  elytra 
  ; 
  in 
  shape 
  and 
  sculpture 
  it 
  

   is 
  like 
  M. 
  glaberrimus, 
  and 
  the 
  hind 
  legs 
  are 
  similar, 
  except 
  that 
  the 
  

   inner 
  carina 
  of 
  the 
  hind 
  tibiae 
  is 
  more 
  distinctly 
  bi-dentate 
  near 
  the 
  

   knee. 
  It 
  might, 
  however, 
  be 
  considered 
  as 
  a 
  colour 
  variety 
  of 
  

   M. 
  glaberrimus, 
  but 
  for 
  the 
  shape 
  of 
  the 
  hind 
  claws 
  which, 
  instead 
  of 
  

   being 
  simple 
  and 
  cleft, 
  are 
  distinctly 
  double 
  in 
  both 
  sexes, 
  the 
  inner 
  

   one 
  being 
  a 
  little 
  more 
  than 
  half 
  the 
  length 
  of 
  the 
  outer, 
  and 
  both 
  

   are 
  cleft.
