  border. 
  Tlie 
  thorax 
  is 
  obscurely 
  red, 
  with 
  reddish 
  pubes- 
  

   cence. 
  On 
  comparison 
  of 
  these 
  specimens 
  with 
  the 
  types, 
  

   and 
  with 
  a 
  ? 
  undoubtedly 
  rubricollis, 
  Lew., 
  in 
  the 
  British 
  

   INTuseum 
  {Staiidinger, 
  1898), 
  I 
  consider 
  that 
  the 
  latter 
  is 
  

   merely 
  a 
  small 
  colour-variety 
  o£ 
  laticollis, 
  Lew. 
  

  

  P. 
  higonice, 
  Lew., 
  is 
  very 
  doubtfully 
  specifically 
  distinct 
  

   from 
  P.japonica, 
  Heyd.

  flavilabris,

  The 
  single 
  c? 
  specimen 
  was 
  included 
  

   by 
  Mr. 
  Lewis 
  with 
  P. 
  aurita, 
  Lew., 
  which 
  at 
  first 
  sight 
  it 
  

   reseml)les. 
  The 
  vertex 
  of 
  the 
  head 
  is, 
  as 
  it 
  were, 
  pressed 
  

   forwards 
  so 
  as 
  to 
  overhang 
  the 
  transverse 
  excavation, 
  as 
  in 
  

   atripennis^ 
  Lew., 
  and 
  episcopaUs, 
  Lew. 
  ; 
  but 
  in 
  flavilabris 
  

   the 
  overhanging 
  edge 
  is 
  rounded 
  in 
  front 
  instead 
  of 
  being 
  

   truncate. 
  The 
  lower 
  part 
  of 
  the 
  face 
  is 
  yellow, 
  in 
  strong 
  

   contrast 
  to 
  the 
  black 
  upper 
  part 
  of 
  the 
  head 
  ; 
  the 
  palpi 
  and 
  

   legs 
  are 
  piceous. 
  The 
  thorax 
  is 
  black, 
  with 
  the 
  scutellum 
  

   and 
  eiytra 
  fulvous.

  These 
  three 
  species 
  — 
  atripennis, 
  Lew., 
  ejnscopalis, 
  Lew., 
  

   and 
  flavilabris, 
  mihi 
  — 
  form 
  one 
  of 
  the 
  most 
  sharply 
  marked 
  

   natural 
  groups 
  of 
  the 
  genus, 
  closely 
  allied 
  to 
  japonica, 
  Heyd. 
  ; 
  

   but 
  it 
  is 
  purely 
  accidental 
  that 
  they 
  have 
  come 
  together 
  in 
  

   the 
  present 
  scheme 
  of 
  tabulation 
  ; 
  ni(/ricolor, 
  Pic, 
  belongs 
  to 
  

   a 
  very 
  different 
  group. 
  

  

  P. 
  nigricolor, 
  Pic, 
  is 
  another 
  species 
  described 
  from 
  the 
  

   2 
  only. 
  A 
  c? 
  in 
  the 
  Fry 
  Collection 
  (Perak, 
  Doherty) 
  has 
  

   the 
  head 
  rather 
  feebly 
  impressed 
  between 
  the 
  eyes. 
  Tlie 
  

   basal 
  joint 
  of 
  the 
  antennse 
  is 
  elongate, 
  feebly 
  incrassate, 
  the 
  

   second 
  not 
  dentate 
  within, 
  joints 
  3-10 
  expanded, 
  serrate- 
  

   pectinate, 
  with 
  the 
  branches 
  very 
  long 
  and 
  fine. 
  

  

  P. 
  ruficollis,

  cannot 
  be 
  maintained 
  as 
  specifically 
  

   distinct

  red 
  colour 
  at 
  the 
  base

   the

  is 
  not

  the 
  only 
  satis- 
  

   factory 
  difference 
  appears 
  to 
  be 
  in 
  the

   black 
  in
