  penicillate 
  at 
  the 
  angle, 
  upper 
  lobe 
  of 
  maxillae 
  short, 
  very 
  transverse, 
  

   thickly 
  penicillate, 
  inner 
  lobe 
  stiffly 
  ciliate, 
  apical 
  joint 
  of 
  labial 
  palpi 
  

   swollen, 
  pyriform, 
  apical 
  joint 
  of 
  maxillary 
  ones 
  fusiform 
  not 
  sharply 
  

   acuminate 
  at 
  the 
  tip 
  ; 
  head 
  with 
  the 
  clypeus 
  somewhat 
  short, 
  quadri- 
  

   dentate 
  at 
  the 
  tip, 
  broad 
  and 
  reflexed 
  somewhat 
  in 
  the 
  manner 
  of 
  

   Scarabceus 
  ; 
  prothorax 
  convex, 
  attenuate 
  laterally 
  in 
  the 
  anterior 
  

   part 
  and 
  thence 
  nearly 
  parallel, 
  base 
  not 
  very 
  arcuate 
  ; 
  scutellum 
  

   short, 
  sharp 
  at 
  tip 
  ; 
  elytra 
  not 
  much 
  ampliated 
  at 
  the 
  humeral 
  part, 
  

   very 
  slightly 
  emarginate 
  below 
  it 
  or 
  not 
  at 
  all 
  (atetichoides) 
  and 
  not 
  

   strongly 
  attenuate 
  thence 
  towards 
  the 
  apex 
  ; 
  pygidium 
  in 
  the 
  male 
  

   slightly 
  declivous 
  forwards 
  ; 
  anterior 
  tibiae 
  tri-dentate, 
  the 
  teeth 
  

   equally 
  distant 
  from 
  each 
  other, 
  and 
  with 
  the 
  apical 
  one 
  only 
  slightly 
  

   curved, 
  all 
  the 
  claws 
  double 
  with 
  the 
  smaller 
  ones 
  half 
  the 
  length 
  of 
  

   the 
  outer, 
  which 
  in 
  the 
  intermediate 
  and 
  posterior 
  legs 
  are 
  deeply 
  cleft. 
  

   In 
  the 
  male 
  the 
  intermediate 
  claws 
  have 
  a 
  tooth 
  underneath 
  more 
  or 
  

   less 
  similar 
  in 
  shape 
  to 
  that 
  of 
  some 
  Monochelus. 
  The 
  genus 
  

   includes 
  four 
  species, 
  one 
  of 
  which, 
  M. 
  atrox, 
  which 
  I 
  have 
  not 
  seen, 
  

   might 
  prove 
  to 
  be 
  identical 
  with 
  M. 
  natalensis, 
  but 
  Burmeister's 
  

   description 
  of 
  it 
  is 
  far 
  from 
  satisfactory. 
  The 
  genus 
  is 
  purely 
  South 
  

   African.

  Elytra

  entirely 
  covered 
  with 
  minute 
  contiguous

   sub-squamose

  well 
  as 
  with 
  a

  the 
  two 
  median

  project 
  

   far 
  beyond 
  the 
  other 
  two, 
  which 
  are 
  not 
  in 
  a 
  line 
  and 
  are 
  almost 
  

   sub-lateral 
  and 
  rounded 
  at
