  parallel, 
  strongly 
  dentate 
  at 
  apex 
  ; 
  prothorax 
  distinctly 
  narrowed 
  

   diagonally 
  in 
  the 
  anterior 
  part, 
  thence 
  sub-parallel 
  for 
  three-fourths 
  of 
  

   the 
  length, 
  deeply 
  pitted, 
  clothed 
  with 
  slightly 
  flavescent 
  hairs 
  ; 
  

   scutellum 
  long, 
  sharp, 
  longer 
  than 
  broad 
  and 
  set 
  with 
  dense 
  scales 
  ; 
  

   elytra 
  very 
  well 
  developed 
  at 
  the 
  shoulders 
  and 
  gradually 
  attenuated 
  

   laterally 
  from 
  there 
  to 
  the 
  apex 
  where 
  they 
  are 
  less 
  than 
  half 
  the 
  

   width 
  of 
  the 
  basal 
  part, 
  they 
  have 
  on 
  each 
  side 
  three 
  somewhat 
  

   deep 
  longitudinal 
  furrows 
  which 
  reach 
  barely 
  to 
  two 
  -thirds 
  of 
  the 
  

   length 
  and 
  are 
  filled 
  with 
  the 
  appressed 
  scales 
  ; 
  pygidium 
  vertical, 
  

   abdominal 
  segments 
  not 
  constricted 
  in 
  the 
  centre 
  and 
  covered 
  

   with 
  yellow 
  scales 
  ; 
  pectus 
  clothed 
  with 
  flavescent 
  hairs 
  ; 
  anterior 
  

   tibiae 
  tri-dentate, 
  the 
  two 
  apical 
  teeth 
  are 
  slightly 
  connate 
  at 
  the 
  

   base 
  and 
  the 
  basal 
  tooth 
  is 
  as 
  strong 
  as 
  the 
  other 
  two, 
  but 
  is 
  set 
  

   somewhat 
  far 
  from 
  them 
  ; 
  the 
  hind 
  femora 
  are 
  greatly 
  developed 
  and 
  

   simple, 
  the 
  tibiae 
  are 
  very 
  swollen 
  but 
  narrower 
  at 
  the 
  apex 
  than 
  at 
  

   the 
  base, 
  simple, 
  with 
  the 
  apical 
  spur 
  very 
  distinct 
  ; 
  the 
  four 
  basal 
  

   joints 
  of 
  the 
  tarsi 
  are 
  distinct 
  but 
  fused, 
  transverse 
  and 
  angular 
  

   inwardly, 
  the 
  fifth 
  joint 
  is 
  very 
  massive, 
  curved 
  and 
  uni-dentate 
  

   near 
  the 
  base, 
  the 
  claw 
  is 
  as 
  long 
  as 
  the 
  fifth 
  joint, 
  and 
  simple 
  ; 
  the 
  

   female 
  is 
  like 
  the 
  male, 
  but 
  less 
  robust, 
  the 
  scales 
  are 
  a 
  deeper 
  

   yellow, 
  and 
  the 
  legs 
  are 
  red.

  The 
  description 
  of 
  P. 
  altemans 
  applies 
  very 
  nearly 
  to 
  this 
  species 
  

   which 
  is, 
  however, 
  smaller, 
  and 
  is 
  therefore 
  comparatively 
  less 
  robust 
  ; 
  

   the 
  colour, 
  including 
  that 
  of 
  the 
  hind 
  legs, 
  is 
  entirely 
  black 
  in 
  the 
  

   male, 
  but 
  the 
  elytra 
  and 
  also 
  the 
  hind 
  legs 
  are 
  red 
  in 
  the 
  female, 
  and 
  

   the 
  basal 
  tooth 
  of 
  the 
  anterior 
  tibiae 
  is 
  not 
  quite 
  so 
  remote 
  ; 
  the 
  

   scales 
  are 
  white 
  in 
  the 
  male 
  and 
  yellow 
  in 
  the 
  female, 
  the 
  median 
  

   longitudinal 
  band 
  of 
  the 
  prothorax 
  and 
  the 
  four 
  small 
  spots 
  are 
  

   similar, 
  but 
  at 
  the 
  base 
  of 
  the 
  elytra 
  there 
  are 
  on 
  each 
  side 
  two 
  small 
  

   scaly 
  patches 
  ; 
  the 
  supra-marginal 
  sulcus 
  alone 
  is 
  filled 
  with 
  an 
  

   uninterrupted 
  band 
  of 
  scales, 
  white 
  or 
  yellow 
  according 
  to 
  the 
  sex, 
  

   and 
  the 
  juxta-sutural 
  and 
  discoidal 
  ones 
  are 
  twice 
  or 
  thrice 
  interrupted 
  ;
