  Philonthus 
  cunctator, 
  n. 
  sp. 
  (Group 
  6, 
  Erichson.) 
  

  

  Angustulus, 
  niger, 
  elytris 
  seneis, 
  antennarum 
  basi 
  apiceque 
  pedi- 
  

   busque 
  testaceis, 
  abdominis 
  segmentorum 
  marginibus 
  posterioribus 
  

   ferrugineis 
  ; 
  capite 
  anguste 
  ovato 
  ; 
  elytris 
  abdomineque 
  dense 
  

   punctatis. 
  

  

  Long. 
  8 
  millim. 
  

  

  Antennae 
  elongate, 
  very 
  slender, 
  fuscous, 
  with 
  the 
  two 
  

   basal 
  joints 
  and 
  the 
  apical 
  joint 
  yellow 
  ; 
  palpi 
  yellow. 
  Head 
  

   very 
  narrow, 
  only 
  half 
  as 
  broad 
  as 
  the 
  thorax 
  ; 
  this 
  latter 
  

   elongate, 
  narrowed 
  in 
  front, 
  the 
  punctures 
  of 
  the 
  dorsal 
  series 
  

   rather 
  fine. 
  Elytra 
  closely 
  and 
  finely 
  punctate. 
  Hind 
  body 
  

   with 
  the 
  hind 
  margins 
  of 
  the 
  segments 
  reddish, 
  those 
  at 
  the 
  

   base 
  only 
  narrowly 
  so, 
  those 
  at 
  the 
  extremity 
  broadly 
  ; 
  ter- 
  

   minal 
  styles 
  elongate, 
  their 
  extreme 
  base 
  and 
  the 
  median 
  lobe 
  

   red. 
  Legs 
  clear 
  yellow, 
  middle 
  coxa? 
  contiguous 
  ; 
  male 
  with 
  

   the 
  anterior 
  tarsi 
  slightly 
  dilated 
  and 
  an 
  extremely 
  slight 
  

   excision 
  of 
  the 
  last 
  ventral 
  segment. 
  

  

  This 
  species 
  is 
  allied 
  to 
  P. 
  jumarius, 
  though 
  abundantly 
  

   distinct 
  by 
  a 
  number 
  of 
  characters. 
  

  

  A 
  single 
  example 
  was 
  met 
  with 
  at 
  Yokohama 
  on 
  the 
  27th 
  

   October, 
  1881. 
  

  

  Philonthus 
  spadiceus, 
  n. 
  sp. 
  (Group 
  7, 
  Erichson.) 
  

  

  Elongatus, 
  depressus, 
  nigerrimus 
  ; 
  antennis 
  palpisque 
  piceis, 
  illis 
  

   gracilibus, 
  elougatis 
  ; 
  elytris 
  abdoiniueque 
  crebrius 
  punctatis, 
  

   illis 
  sat 
  nitidis. 
  

  

  Long. 
  10-11 
  millim. 
  

  

  Antennas 
  rather 
  longer 
  than 
  head 
  and 
  thorax, 
  not 
  thicker 
  

   externally, 
  quite 
  slender, 
  the 
  penultimate 
  joint 
  much 
  longer 
  

   than 
  broad. 
  Head 
  suboblong, 
  densely 
  punctate 
  at 
  the 
  vertex 
  

   and 
  the 
  sides 
  of 
  the 
  eyes. 
  Thorax 
  elongate 
  and 
  slender, 
  

   nearly 
  parallel-sided, 
  with 
  a 
  dorsal 
  series 
  of 
  eight 
  rather 
  large 
  

   punctures, 
  this 
  series 
  more 
  or 
  less 
  irregular, 
  and 
  frequently 
  

   with 
  one 
  or 
  two 
  additional 
  punctures 
  intercalated. 
  Elytra 
  

   quite 
  black, 
  flat, 
  very 
  finely 
  pubescent, 
  finely 
  punctate, 
  a 
  little 
  

   shining. 
  Hind 
  body 
  densely 
  punctate. 
  Femora 
  picescent 
  ; 
  

   middle 
  coxas 
  rather 
  narrowly 
  separated 
  ; 
  front 
  tarsi 
  of 
  female 
  

   a 
  little, 
  of 
  male 
  much, 
  dilated 
  ; 
  the 
  latter 
  sex 
  with 
  a 
  rather 
  

   broad, 
  not 
  deep, 
  emargination 
  on 
  the 
  last 
  ventral 
  plate. 
  

  

  This 
  is 
  allied 
  to 
  P. 
  prolatus, 
  but 
  is 
  readily 
  distinguished 
  

   by 
  the 
  longer 
  and 
  more 
  slender 
  antennae, 
  by 
  the 
  deeper 
  

   black 
  colour, 
  longer 
  and 
  flatter 
  elytra 
  with 
  less 
  conspicuous 
  

   pubescence, 
  and 
  by 
  the 
  additional 
  puncture 
  in 
  the 
  thoracic
