  the 
  apex, 
  the 
  sides 
  raised 
  and 
  forming 
  carinae, 
  within 
  which 
  

   are 
  two 
  carina? 
  converging 
  towards 
  the 
  apex 
  and 
  enclosing 
  an 
  

   inner 
  rugulose 
  area, 
  raised 
  above 
  the 
  lateral 
  margins. 
  The 
  

   first 
  recurrent 
  nervure 
  is 
  rather 
  nearer 
  to 
  the 
  second 
  cubital 
  

   eel! 
  than 
  in 
  the 
  male.

  The 
  male 
  is 
  the 
  type. 
  

  

  In 
  the 
  almost 
  complete 
  absence 
  of 
  the 
  appendix 
  to 
  the 
  

   radial 
  cell 
  this 
  species 
  agrees 
  with 
  lati/rons, 
  Kohl. 
  The 
  

   second 
  cubital 
  cell 
  is 
  very 
  narrowly 
  triangular, 
  so 
  that 
  the 
  

   distance 
  between 
  the 
  recurrent 
  nervures 
  is 
  no 
  greater 
  than 
  is 
  

   usual 
  in 
  the 
  genus, 
  although 
  in 
  this 
  species 
  the 
  first 
  recurrent 
  

   is 
  received 
  by 
  the 
  first 
  cubital 
  cell. 
  The 
  third 
  cubital 
  cell 
  

   is 
  almost 
  rectangular. 
  In 
  the 
  form 
  of 
  the 
  apical 
  segment 
  

   in 
  the 
  male 
  the 
  species 
  is 
  isolated, 
  differing 
  from 
  all 
  others, 
  

   the 
  dorsal 
  plate 
  being 
  much 
  broader 
  than 
  in 
  P. 
  saundersi, 
  

   Morice, 
  the 
  only 
  other 
  species, 
  so 
  far 
  as 
  I 
  know, 
  in 
  which 
  

   there 
  are 
  no 
  spines 
  or 
  bifurcation. 
  

  

  P. 
  saundersi 
  may 
  prove 
  to 
  be 
  the 
  male 
  of 
  dongalensis,

  The

  one 
  of 
  each 
  

   sex, 
  collected 
  by 
  T. 
  Fukai 
  at 
  Horisha, 
  Formosa. 
  I 
  also 
  find 
  

   a 
  male 
  in 
  the 
  Sauter

  from 
  the 
  Berlin 
  Museum, 
  

   collected

  is 
  

   about 
  12 
  mm. 
  long, 
  narrow, 
  with 
  pubescence 
  much 
  as

  abdomen 
  with 
  narrow 
  entire 
  red 
  hair-bands, 
  and 
  

   some 
  red 
  hair 
  in 
  the 
  basal 
  depressions 
  of 
  the 
  segments, 
  the 
  

   face 
  with 
  much 
  red 
  hair, 
  the 
  vertex 
  and 
  disc 
  of 
  thorax 
  with 
  

   a 
  good 
  deal 
  of 
  black 
  hair. 
  The 
  mandibles 
  are 
  quadndentate, 
  

   the 
  teeth 
  sharp, 
  the 
  second 
  one 
  smaller 
  than 
  the 
  others 
  ; 
  

   antennae 
  long 
  and 
  black 
  ; 
  anterior 
  coxae 
  with 
  short 
  spines, 
  

   bidden 
  among 
  the 
  hairs 
  ; 
  anterior 
  tibiae 
  and 
  tarsi 
  simple 
  ; 
  

   sixth 
  abdominal 
  segment 
  retracted, 
  its 
  upper 
  surface 
  granular, 
  

   elevated 
  in 
  the 
  middle, 
  and 
  with 
  only 
  scattered 
  erect 
  dark 
  

   hairs 
  in 
  the 
  Kanshirei 
  specimen, 
  but 
  in 
  the 
  other 
  with 
  some 
  

   appressed 
  pale 
  yellow 
  tomentum 
  in 
  the 
  middle;

  of
