  A 
  Revision 
  of 
  

  

  P. 
  inapicalis, 
  Pic 
  — 
  A 
  ,^ 
  in 
  the 
  Fry 
  Collection 
  at 
  the 
  

   British 
  Museum 
  (Perak, 
  Doherii/) 
  has 
  the 
  head 
  transversely 
  

   impressed 
  between 
  the 
  eyes, 
  with 
  the 
  vertex 
  slightly 
  raised 
  ; 
  

   the 
  front 
  portion 
  of 
  the 
  head 
  between 
  the 
  antennae 
  is 
  tri- 
  

   gibbous, 
  the 
  gibbosities 
  being 
  arranged 
  transversely 
  and 
  

   encroaching 
  upon 
  the 
  transverse 
  impression. 
  The 
  antennae 
  

   are 
  rather 
  stout, 
  the 
  basal 
  joint 
  moderately 
  incrassate, 
  the 
  

   second 
  joint 
  sharply 
  dentate 
  within 
  ; 
  joints 
  3-10 
  suhequal, 
  

   expanded, 
  each 
  with 
  a 
  fine 
  branch 
  arising 
  out 
  of 
  the 
  apex 
  of 
  

   the 
  expansion. 
  

  

  P. 
  testaceipennis, 
  PiC; 
  is 
  possibly 
  only 
  a 
  variety 
  of 
  inapicalis. 
  

   Pic. 
  It 
  is 
  smaller 
  and 
  more 
  slenderly 
  built, 
  with 
  the 
  trans- 
  

   verse 
  impression 
  of 
  the 
  head 
  in 
  the 
  c? 
  less 
  deep, 
  but 
  the 
  

   structure 
  of 
  the 
  head 
  and 
  antennae 
  are 
  essentially 
  the 
  same 
  

   as 
  in 
  inapicalis. 
  

  

  P. 
  brevitarsis, 
  Lew., 
  was 
  described 
  upon 
  ? 
  specimens 
  

   only, 
  but

  are 
  in 
  the 
  Paris 
  Museum

  Harmand^ 
  

   1906) 
  that 
  I 
  have 
  little 
  hesitation 
  in 
  referring 
  to 
  this 
  species. 
  

  

  The 
  head 
  of 
  the 
  ^ 
  has 
  a 
  deep 
  transverse 
  excavation 
  

   between 
  the 
  eyes, 
  above 
  the 
  base 
  of 
  the 
  antennae 
  ; 
  this 
  cleft 
  

   is 
  nearly 
  closed 
  in 
  the 
  middle 
  by 
  the 
  forward 
  projection 
  of 
  

   the 
  vertex, 
  itself 
  deeply 
  impressed. 
  This 
  impression 
  forms 
  a 
  

   sharp 
  edge 
  overhanging 
  the 
  transverse 
  cleft, 
  and 
  dies 
  away 
  

   gradually 
  behind. 
  The 
  lower 
  part 
  of 
  the 
  face 
  below 
  the 
  

   cleft 
  has 
  two 
  oblique 
  pyriform 
  impressions 
  with 
  their 
  points 
  

   converging 
  near 
  the 
  middle 
  of 
  the 
  anterior 
  edge 
  of 
  the 
  cleft. 
  

   The 
  first 
  two 
  joints 
  of 
  the 
  antennae 
  are 
  incrassate 
  and 
  

   shining, 
  the 
  rest 
  opaque, 
  the 
  third 
  strongly 
  produced, 
  4-10 
  

   each 
  with 
  a 
  long 
  slender 
  branch. 
  The 
  sculpture 
  of 
  the 
  head 
  

   approaches 
  very 
  nearly 
  that 
  of 
  P. 
  aurita, 
  Lew., 
  in 
  which, 
  

   however, 
  the 
  vertex 
  is 
  not 
  pressed 
  forward 
  over 
  the 
  trans- 
  

   verse 
  excavation. 
  In 
  the 
  latter 
  species, 
  too, 
  the 
  lower 
  part 
  of 
  

   the 
  face 
  is 
  rough 
  and 
  swollen, 
  and 
  the 
  oblique 
  impressions 
  

   are 
  much 
  smaller. 
  

  

  P. 
  laticollis, 
  Lew. 
  — 
  This 
  species 
  also 
  was 
  described 
  upon 
  $ 
  

   specimens 
  only, 
  but 
  a 
  ^ 
  in 
  the 
  Paris 
  Museum 
  (Mt. 
  Takao, 
  

   E. 
  Gallois, 
  18. 
  iv. 
  09) 
  appears 
  to 
  be 
  conspecific 
  with 
  two 
  ? 
  $ 
  

   from 
  the 
  same 
  locality 
  (23. 
  iv. 
  11) 
  that 
  I 
  identify 
  with 
  

   laticollis, 
  Lew. 
  The 
  sculpture 
  of 
  the 
  head 
  is 
  that 
  of 
  ritbri- 
  

   cullis, 
  Lew., 
  viz., 
  a 
  very 
  broad 
  and 
  distinct 
  transverse 
  depres- 
  

   sion 
  occupying 
  the 
  greater 
  part 
  of 
  the 
  front 
  of 
  the 
  liead, 
  

   almost 
  divided 
  by 
  a 
  median 
  carina 
  arising 
  from 
  its 
  anterior
