  part, 
  and 
  having 
  a 
  short, 
  discoidal 
  impression 
  along 
  the 
  humeral 
  

   callus, 
  they 
  are 
  closely 
  punctate, 
  and 
  very 
  slightly 
  pubescent, 
  the 
  

   pubescence 
  is 
  denser 
  along 
  the 
  suture 
  ; 
  anterior 
  tibiae 
  tri-dentate, 
  

   the 
  teeth 
  are 
  equi-distant, 
  but 
  the 
  basal 
  one 
  is 
  small. 
  

  

  Female 
  : 
  Shape 
  of 
  the 
  male, 
  but 
  the 
  elytra 
  are 
  red, 
  the 
  prothorax 
  

   greener, 
  and 
  the 
  pubescence 
  on 
  it 
  is 
  not 
  as 
  long 
  as 
  in 
  the 
  male, 
  

   the 
  appressed 
  hairs 
  are 
  more 
  evenly 
  spread 
  and 
  do 
  not 
  form 
  a 
  band 
  

   along 
  the 
  suture 
  ; 
  the 
  legs 
  are 
  piceous 
  red. 
  Some 
  of 
  the 
  females 
  

   have 
  partly 
  fuscous 
  elytra.

  Very 
  closely 
  allied 
  to 
  P. 
  discolor; 
  the 
  male 
  has 
  also 
  the 
  elytra 
  

   aeneo-fuscate, 
  and 
  redder 
  along 
  the 
  sides, 
  and 
  in 
  the 
  female 
  the 
  

   elytra 
  are 
  brownish 
  red 
  ; 
  the 
  only 
  difference 
  is 
  to 
  be 
  found 
  in 
  the 
  

   shape 
  of 
  the 
  clypeus 
  which 
  in 
  the 
  male 
  is 
  straight 
  at 
  apex 
  with 
  

   the 
  angles 
  sharp 
  and 
  plainly 
  reflexed, 
  while 
  in 
  the 
  female 
  these 
  

   angles 
  are 
  more 
  rounded 
  than 
  in 
  P. 
  discolor.

  Male 
  : 
  Quite 
  similar 
  in 
  general 
  facies 
  to 
  P. 
  semi-virgatus, 
  but 
  

   much 
  smaller 
  ; 
  the 
  colour 
  and 
  sculpture 
  are 
  alike, 
  the 
  prothorax 
  

   especially 
  is 
  very 
  metallic 
  ; 
  in 
  the 
  male 
  the 
  clypeus 
  is 
  sharp 
  laterally 
  

   and 
  has 
  a 
  very 
  slight 
  prominence 
  in 
  the 
  centre 
  ; 
  the 
  elytra 
  have 
  the 
  

   same 
  vestiture, 
  the 
  pygidial 
  part 
  is 
  equally 
  hairy, 
  and 
  the 
  only 
  

   difference 
  between 
  the 
  two 
  species 
  is 
  to 
  be 
  found 
  in 
  the 
  shape 
  of 
  the 
  

   two 
  basal 
  teeth 
  of 
  the 
  anterior 
  tibiae 
  which 
  in 
  P. 
  nitidulus 
  are 
  

   separate, 
  whereas 
  in 
  P. 
  semi-virgatus 
  these 
  are 
  set 
  very 
  close 
  to 
  

   each 
  other, 
  almost 
  connate.

  Platychelus 
  eetensus, 
  n. 
  spec. 
  

  

  Male 
  : 
  Dark 
  bronze, 
  a 
  little 
  more 
  shiny 
  on 
  the 
  prothorax 
  than 
  on 
  

   the 
  rest 
  of 
  the 
  body 
  ; 
  clypeus 
  very 
  rugose, 
  straight 
  laterally 
  and
