  Hab. 
  Cape

  Hope. 
  A 
  peculiarly 
  depressed 
  species." 
  

  

  This 
  species 
  is 
  not 
  a 
  Dichelus 
  or 
  an 
  Heterochelus, 
  owing 
  to 
  the 
  

   anterior 
  tibiae 
  being 
  bi-dentate 
  outwardly. 
  It 
  may 
  prove 
  to 
  be 
  a 
  

   Platychelus.

  (part). 
  

  

  Mentum 
  long, 
  ovate, 
  emarginate, 
  obliquely 
  attenuate 
  towards 
  the 
  

   apical 
  part 
  where 
  it 
  is 
  emarginate, 
  the 
  angles 
  are 
  sharp, 
  and 
  not 
  

   penicillate, 
  the 
  upper 
  lobe 
  of 
  the 
  maxillae 
  is 
  horny, 
  feebly 
  peni- 
  

   cillate 
  at 
  the 
  tip, 
  hollow, 
  armed 
  on 
  each 
  side 
  with 
  four 
  robust 
  

   somewhat 
  hooked 
  teeth 
  and 
  with 
  an 
  apical 
  one 
  less 
  strongly 
  hooked 
  

   than 
  the 
  others, 
  apical 
  joint 
  of 
  labial 
  and 
  maxillary 
  palpi 
  swollen, 
  

   fusiform, 
  and 
  acuminate 
  ; 
  clypeus 
  reflexed 
  or 
  dentate 
  at 
  the 
  tip, 
  

   short, 
  and 
  without 
  a 
  lateral 
  basal 
  angular 
  projection 
  ; 
  prothorax 
  

   elongate, 
  longer 
  than 
  broad, 
  distinctly 
  narrowed 
  laterally 
  in 
  front 
  for 
  

   one-third 
  of 
  the 
  length, 
  then 
  parallel 
  ; 
  scutellum 
  very 
  long, 
  broad 
  at 
  

   base 
  and 
  sharply 
  triangular 
  ; 
  elytra 
  very 
  strongly 
  sinuated 
  laterally 
  

   and 
  very 
  much 
  narrowed 
  towards 
  the 
  apex 
  ; 
  pygidium 
  vertical 
  and 
  

   very 
  slightly 
  inflexed 
  in 
  the 
  male 
  ; 
  intermediate 
  and 
  posterior 
  legs 
  

   with 
  an 
  apical 
  spur 
  ; 
  anterior 
  tibiae 
  bi- 
  or 
  tri-dentate 
  outwardly, 
  the 
  

   basal 
  teeth 
  at 
  right 
  angles 
  with 
  the 
  tibiae 
  and 
  slightly 
  curved 
  down- 
  

   wards, 
  the 
  apical 
  one 
  slightly 
  more 
  oblique 
  than 
  in 
  Heterochelus 
  ; 
  

   anterior 
  and 
  intermediate 
  claws 
  double, 
  and 
  both 
  cleft, 
  posterior 
  ones 
  

   double 
  or 
  single 
  ; 
  in 
  the 
  male 
  the 
  hind 
  femora 
  and 
  tibiae 
  are 
  some- 
  

   times 
  very 
  strongly 
  dilated 
  and 
  ampliated 
  {axillaris, 
  lobijoes), 
  but 
  

   they 
  are 
  usually 
  only 
  a 
  little 
  more 
  robust 
  than 
  those 
  of 
  the 
  

   female. 
  

  

  The 
  main 
  differences 
  between 
  this 
  genus 
  and 
  Heterochelus 
  are
