  Male 
  : 
  Elongate, 
  black 
  with 
  a 
  bronze 
  tinge, 
  elytra 
  very 
  light 
  

   testaceous, 
  slightly 
  infuscate 
  in 
  the 
  apical 
  part 
  ; 
  head 
  and 
  prothorax 
  

   clothed 
  with 
  a 
  very 
  long, 
  villose, 
  light 
  fulvous 
  pubescence, 
  which 
  is 
  

   nearly 
  equally 
  as 
  long 
  and 
  dense 
  on 
  the 
  abdomen 
  and 
  the 
  pectus 
  ; 
  the 
  

   punctures 
  on 
  the 
  prothorax 
  are 
  not 
  scabrose 
  in 
  the 
  posterior 
  half, 
  

   and 
  there 
  is 
  no 
  median 
  groove 
  ; 
  scutellum 
  densely 
  hairy 
  ; 
  elytra 
  

   elongate, 
  conspicuously 
  emarginate 
  laterally 
  and 
  strongly 
  attenuate 
  

   towards 
  the 
  apex, 
  nearly 
  plane 
  but 
  having 
  a 
  deep 
  transverse 
  im- 
  

   pression 
  in 
  the 
  basal 
  part, 
  and 
  a 
  slight 
  depression 
  along 
  the 
  suture, 
  

   they 
  are 
  covered 
  with 
  somewhat 
  closely 
  set, 
  round, 
  somewhat 
  seriate 
  

   punctures, 
  each 
  bearing 
  a 
  fine 
  sub-appressed, 
  pallid 
  hair, 
  at 
  the 
  apex 
  

   of 
  the 
  suture 
  there 
  is 
  a 
  short 
  band 
  of 
  denser 
  paler 
  hairs 
  on 
  each 
  side; 
  

   pygidium 
  somewhat 
  convex, 
  very 
  closely 
  and 
  very 
  finely 
  punctulate, 
  

   and 
  covered 
  with 
  a 
  slight 
  pallid 
  pubescence 
  w 
  T 
  hich 
  does 
  not 
  conceal 
  

   the 
  black 
  background 
  ; 
  anterior 
  tibiae 
  with 
  a 
  somewhat 
  indistinct 
  

   third 
  outer 
  tooth 
  ; 
  hind 
  legs 
  slender, 
  villose, 
  the 
  hind 
  inner 
  claws 
  are 
  

   two-thirds 
  of 
  the 
  length 
  of 
  the 
  outer, 
  and 
  both 
  distinctly 
  cleft 
  at 
  tip. 
  

  

  Female 
  : 
  Similar 
  to 
  the 
  male, 
  but 
  the 
  elytra 
  are 
  not 
  infuscate 
  

   behind, 
  and 
  the 
  third 
  basal 
  tooth 
  of 
  the 
  anterior 
  tibiae 
  is, 
  although 
  

   very 
  small, 
  sharper 
  and 
  more 
  distinct. 
  

  

  Length 
  7-8 
  mm.

  3^-4

  Hab. 
  Cape 
  Colony 
  (Cape 
  Town, 
  Stellenbosch, 
  Paarl, 
  Malmesbury, 
  

   Worcester). 
  

  

  This 
  species 
  is 
  easily 
  distinguished 
  from 
  the 
  preceding 
  ones 
  by 
  

   the 
  more 
  elongated 
  shape.

  This 
  species 
  might 
  be 
  mistaken 
  for 
  P. 
  lupinus, 
  and 
  I 
  am 
  not 
  sure 
  

   that 
  it 
  is 
  not 
  merely 
  a 
  variety 
  ; 
  it 
  is, 
  however, 
  smaller, 
  and 
  the 
  

   pubescence 
  on 
  the 
  prothorax, 
  under 
  side, 
  and 
  legs 
  is 
  greyish 
  white, 
  

   but 
  the 
  propygidium 
  and 
  pygidium 
  are 
  clothed 
  with 
  very 
  dense 
  

   orange-yellow 
  appressed 
  hairs 
  ; 
  the 
  prothorax 
  is 
  also 
  more 
  shining 
  

   bronze, 
  but 
  occasionally 
  the 
  hairs 
  on 
  the 
  prothorax 
  and 
  under 
  side 
  

   are 
  as 
  fulvous 
  as 
  in 
  P. 
  lupinus, 
  in 
  which 
  case 
  the 
  only 
  distinctive 
  

   character 
  is 
  the 
  background 
  of 
  the 
  scutellum 
  entirely 
  hidden 
  by 
  the
