  combination 
  of 
  red 
  tibiae 
  with 
  black 
  tarsi 
  is 
  a 
  striking 
  

   feature, 
  and 
  throws 
  it 
  entirely 
  out 
  of 
  the 
  table

  mm.,

  a 
  little 
  over 
  18. 
  

  

  Head, 
  thorax, 
  antennae, 
  and 
  legs 
  black, 
  except 
  that 
  the 
  

   flagellum 
  is 
  ferruginous 
  beneath 
  apically 
  (this 
  is 
  not 
  con- 
  

   spicuous), 
  and 
  the 
  tarsi 
  are 
  obscurely 
  reddish 
  at 
  apex 
  ; 
  hair 
  

   of 
  head 
  and 
  thorax 
  greyish 
  white 
  ; 
  head 
  broad 
  ; 
  clypeus 
  

   shining, 
  with 
  sparse 
  distiact 
  punctures

  a 
  strong 
  median 
  

   depression 
  ;

  dark 
  red 
  subapically 
  ; 
  vertex 
  shining 
  ; 
  

   mesothorax 
  and 
  scutellum 
  densely 
  and 
  rather 
  coarsely 
  

   punctured, 
  the 
  shining 
  surface 
  visible 
  between 
  the 
  punctures 
  

   on 
  scutellum 
  and 
  hind 
  part 
  of 
  mesothorax 
  ; 
  tubercles 
  densely 
  

   fringed 
  with 
  white 
  hair 
  ; 
  area 
  of 
  metathorax 
  peculiar, 
  the 
  

   hind 
  margin 
  thickened 
  and 
  obtuse, 
  but 
  interrupted 
  in 
  middle, 
  

   so 
  that 
  the 
  rather 
  narrow 
  area 
  proper, 
  which 
  is 
  finely 
  

   obliquely 
  striate, 
  has 
  its 
  hind 
  edge 
  curved 
  on 
  each 
  side 
  and 
  

   pointed 
  in 
  the 
  middle, 
  like 
  a 
  printer^s 
  bracket 
  ; 
  sides 
  of 
  

   metathorax 
  very 
  hairy. 
  Legs 
  with

  conspicuously 
  weakened 
  ; 
  stigma 
  rather 
  small 
  ;

  broad, 
  receiving 
  first 
  r.

  In 
  the 
  table 
  in 
  Ann. 
  & 
  Mag. 
  Nat. 
  Hist., 
  Sept. 
  1904, 
  this 
  

   falls 
  with 
  P. 
  tuchilas, 
  Sm., 
  and 
  P. 
  Uchatus, 
  Sm. 
  In 
  P. 
  tuchilas 
  

   the 
  area 
  of 
  metathorax 
  is 
  bounded 
  by 
  a 
  sharp 
  ridge, 
  and 
  the 
  

   hind 
  margins 
  of 
  the 
  first 
  two 
  abdominal 
  segments 
  are 
  

   darkened. 
  In 
  P. 
  Uchatus 
  the 
  metathorax 
  is 
  also 
  unlike 
  that 
  

   of 
  P. 
  arciferus. 
  From 
  all 
  the 
  similar 
  species, 
  P. 
  arciferus 
  is 
  

   readily 
  known 
  by 
  the 
  tubercle 
  on 
  the 
  second 
  ventral 
  segment 
  

   of 
  abdomen.
