  MONOCHELUS 
  SIMPLICIPES, 
  n. 
  Sp. 
  

  

  Male 
  : 
  Black, 
  with 
  the 
  elytra 
  testaceous 
  red, 
  antennae 
  rufescent 
  

   with 
  the 
  club 
  black; 
  head 
  very 
  rugose, 
  clypeus 
  slightly 
  attenuated 
  

   laterally 
  with 
  the 
  outer 
  angles 
  moderately 
  rounded, 
  and 
  the 
  margins 
  

   somewhat 
  reflexed 
  ; 
  prothorax 
  having 
  instead 
  of 
  a 
  median 
  groove 
  a 
  

   longitudinal, 
  not 
  much 
  raised 
  and 
  rounded 
  costate 
  carina 
  and 
  a 
  

   shallow, 
  but 
  somewhat 
  broad 
  furrow 
  on 
  each 
  side, 
  which, 
  like 
  the 
  

   two 
  median 
  furrows 
  are 
  filled 
  with 
  yellow 
  scales, 
  the 
  median 
  carina 
  is 
  

   impunctate 
  ; 
  and 
  there 
  is 
  also 
  an 
  impunctate 
  longitudinal 
  space 
  

   on 
  each 
  side 
  of 
  the 
  disk 
  ; 
  scutellum 
  rugulose 
  ; 
  elytra 
  deeply 
  and 
  

   irregularly 
  punctate 
  and 
  rugose 
  laterally, 
  and 
  having 
  a 
  distinct 
  costa 
  

   in 
  the 
  discoidal 
  part, 
  the 
  intervals 
  on 
  each 
  side 
  of 
  the 
  costa 
  are 
  

   somewhat 
  deep 
  and 
  broad, 
  humeral 
  callus 
  well 
  developed, 
  the 
  juxta- 
  

   humeral 
  interval 
  is 
  partially 
  filled 
  at 
  the 
  base 
  with 
  greyish-white 
  

   scales, 
  a 
  few 
  of 
  which 
  are 
  very 
  sparsely 
  sprinkled 
  here 
  and 
  there 
  ; 
  

   pygidium 
  black, 
  glabrous 
  ; 
  abdominal 
  segments 
  also 
  glabrous 
  ; 
  pectus 
  

   scaly; 
  anterior 
  tibiae 
  bi-dentate 
  outwardly 
  but 
  incised 
  above 
  the 
  

   second 
  tooth, 
  the 
  incision 
  sharply 
  angular; 
  anterior 
  and 
  interme- 
  

   diate 
  claws 
  somewhat 
  thick, 
  posterior 
  ones 
  with 
  a 
  short, 
  lamellate 
  

   inner 
  one 
  reaching 
  only 
  to 
  one-fourth 
  of 
  the 
  length 
  of 
  the 
  outer 
  one, 
  • 
  

   both 
  claws 
  are 
  simple 
  ; 
  hind 
  femora 
  robust, 
  simple, 
  trochanters 
  not 
  

   spinose 
  ; 
  hind 
  tibiae 
  elongated 
  and 
  moderately 
  dilated 
  at 
  the 
  apex, 
  

   somewhat 
  compressed 
  outwardly, 
  slightly 
  concave 
  inwardly 
  but 
  

   more 
  deeply 
  scooped 
  at 
  the 
  tip, 
  the 
  apices 
  of 
  the 
  groove 
  are 
  very 
  

   sharply 
  angular, 
  the 
  inner 
  one 
  being 
  sub-mucronate, 
  and 
  there 
  is 
  

   a 
  small 
  apical 
  spur. 
  

  

  I 
  have 
  seen 
  one 
  male 
  example 
  only, 
  and 
  it 
  is 
  quite 
  possible 
  that 
  

   this 
  specimen 
  had 
  partly 
  lost 
  his 
  scaly 
  covering. 
  

  

  This 
  is 
  the 
  only 
  Monochelus 
  in 
  which 
  the 
  median 
  part 
  of 
  the 
  pro- 
  

   thorax 
  is 
  bluntly 
  carinate.

  Monochelus 
  jucundus, 
  n. 
  spec. 
  

  

  Male 
  : 
  This 
  species 
  is 
  very 
  closely 
  allied 
  to 
  M. 
  partittis, 
  the 
  facies 
  

   and 
  sculpture 
  are 
  identical, 
  but 
  the 
  elytra 
  are 
  piceous 
  red, 
  and 
  more 
  

   distinctly 
  costate, 
  the 
  scales 
  are 
  whiter 
  and 
  similarly 
  arranged, 
  but 
  

   the 
  hind 
  legs 
  are 
  differently 
  shaped 
  ; 
  the 
  trochanters 
  of 
  the 
  hind 
  

   femora 
  are 
  not 
  produced 
  into 
  a 
  spine, 
  and 
  the 
  hind 
  tibiae 
  are 
  gradually
