  male 
  has 
  a 
  slight 
  emargination 
  on 
  the 
  hind 
  margin 
  of 
  the 
  

   last 
  ventral 
  plate 
  and 
  the 
  following 
  segment 
  is

  Oyayama 
  and 
  Miyanoshita 
  in 
  April 
  and 
  May. 
  

  

  This 
  is 
  the 
  only 
  species 
  in 
  this 
  section 
  that 
  possesses 
  

   spotted 
  elytra. 
  

  

  Stenus 
  palpalis, 
  n. 
  sp. 
  (Sect. 
  II. 
  A, 
  Erichson.) 
  

  

  Nigerrimus, 
  nitidus, 
  subcylindricus 
  ; 
  antennis, 
  palpis 
  pedibusque 
  

   rufo-testaceis, 
  illarum 
  clava 
  fuscescente 
  ; 
  fortiter 
  rugoso-punc- 
  

   tatus 
  ; 
  elytris 
  thoraceque 
  longitudine 
  sequalibus 
  ; 
  abdomine 
  obso- 
  

   lete 
  marginato. 
  

  

  Long. 
  6 
  railliru. 
  

  

  Palpi 
  extremely 
  long. 
  Head 
  very 
  broad, 
  broader 
  than 
  the 
  

   elytra, 
  not 
  excavate, 
  with 
  two 
  broad 
  vague 
  grooves. 
  Thorax 
  

   about 
  as 
  long 
  as 
  broad, 
  rounded 
  at 
  the 
  sides 
  and 
  much 
  nar- 
  

   rowed 
  behind, 
  coarsely, 
  deeply, 
  and 
  very 
  densely 
  punctate. 
  

   Elytra 
  extremely 
  coarsely 
  punctate, 
  very 
  slightly 
  narrowed 
  

   at 
  the 
  shoulders. 
  Hind 
  body 
  sparingly 
  punctate, 
  the 
  punc- 
  

   tures 
  at 
  the 
  base 
  very 
  coarse, 
  on 
  the 
  apical 
  segment 
  much 
  

   less 
  so. 
  Tarsal 
  lobes 
  large. 
  The 
  male 
  characters 
  are 
  slight, 
  

   but 
  there 
  is 
  in 
  that 
  sex 
  a 
  broad, 
  rather 
  shallow, 
  angular 
  

   notch 
  on 
  the 
  last 
  ventral 
  plate. 
  

  

  Ichiuchi 
  and 
  Sendai 
  ; 
  two 
  specimens. 
  

  

  This 
  is 
  somewhat 
  similar 
  to 
  8. 
  subcylindricus, 
  Scriba, 
  but 
  

   is 
  much 
  closer 
  to 
  an 
  undescribed 
  species 
  from 
  Amurland. 
  It 
  

   connects 
  the 
  species 
  of 
  this 
  section 
  with 
  those 
  of 
  the 
  following, 
  

   being 
  similar 
  to 
  S. 
  mysticus 
  ; 
  that 
  species 
  possesses 
  traces 
  of 
  

   the 
  lateral 
  margin 
  on 
  each 
  of 
  the 
  segments 
  of 
  the 
  hind 
  body 
  

   in 
  the 
  form 
  of 
  a 
  single 
  raised 
  line 
  ; 
  but 
  in 
  8. 
  palpalis 
  there 
  

   are 
  two 
  raised 
  lines 
  on 
  each 
  segment, 
  so 
  that 
  the 
  side-margin 
  

   exists, 
  though 
  not 
  raised 
  or 
  prominent.

  breviterque 
  albido-pubescens 
  ;

  fuscis 
  ;

  the 
  vertex 
  and 
  very 
  slightly 
  

   depressed 
  on 
  each 
  side.

  longer 
  than 
  broad, 
  rather 
  

   closely 
  punctate,

  indistinct, 
  rather 
  short, 
  smooth

  on 
  the
