  mentis 
  duobus 
  basalibus 
  marginibus 
  flavo-maculatis 
  ; 
  femoribus 
  

   ad 
  basin 
  nigris 
  ; 
  elytris 
  punctis 
  adjectis 
  numerosis. 
  

   Long. 
  8-10 
  millim. 
  

  

  This 
  differs 
  from 
  0. 
  niaculiventris 
  not 
  only 
  in 
  the 
  colour 
  of 
  

   the 
  antennae 
  and 
  palpi, 
  but 
  also 
  in 
  other 
  characters 
  which, 
  

   though 
  not 
  so 
  conspicuous 
  at 
  first 
  sight, 
  are 
  really 
  more 
  

   important. 
  The 
  thorax 
  is 
  longer 
  and 
  the 
  elytra 
  possess 
  

   numerous 
  irregularly 
  placed 
  punctures, 
  amidst 
  which 
  the 
  two 
  

   lines 
  of 
  serial 
  punctures 
  are 
  not 
  very 
  definite 
  ; 
  the 
  large 
  

   black 
  patch 
  at 
  the 
  outer 
  angle 
  of 
  the 
  elytra 
  extends 
  inwards 
  

   and 
  meets 
  its 
  fellow 
  of 
  the 
  opposite 
  side 
  ; 
  the 
  femora 
  are 
  

   black 
  at 
  the 
  base 
  and 
  the 
  tibia? 
  a 
  little 
  infuscate 
  at 
  the 
  base 
  

   and 
  apex. 
  

  

  I 
  have 
  seen 
  only 
  two 
  specimens. 
  

  

  Oxyporus 
  germanus, 
  n. 
  sp. 
  

  

  Niger 
  ; 
  palpis, 
  pedibus, 
  elytris 
  abdominisque 
  marginibus 
  lateralibus 
  

   pallide 
  flavis 
  ; 
  antennis 
  rufis 
  ; 
  elytris 
  sutura 
  anguste 
  maculaque 
  

   ad 
  angulum 
  externum 
  nigris. 
  

  

  Long. 
  7-10 
  millim. 
  

  

  Very 
  closely 
  allied 
  to 
  the 
  North-American 
  0. 
  vittatus, 
  

   Grav., 
  but 
  differing 
  in 
  several 
  minor 
  points. 
  The 
  head 
  is 
  

   less 
  elongate 
  ; 
  the 
  black 
  colour 
  of 
  the 
  suture 
  of 
  the 
  elytra 
  is 
  

   not 
  at 
  all 
  dilated 
  in 
  front 
  ; 
  the 
  terminal 
  two 
  segments 
  of 
  the 
  

   hind 
  body 
  are 
  entirely 
  black, 
  while 
  the 
  whole 
  of 
  the 
  raised 
  

   margins 
  of 
  the 
  preceding 
  segments 
  are 
  pallid 
  yellow, 
  and 
  this 
  

   colour 
  extends 
  inwards 
  at 
  the 
  front 
  angle 
  of 
  each 
  segment, 
  so 
  

   as 
  to 
  surround 
  the 
  stigmata. 
  The 
  legs, 
  including 
  the 
  coxas, 
  

   are 
  entirely 
  pallid 
  yellow, 
  but 
  the 
  breast 
  is 
  all 
  black. 
  There 
  

   are 
  but 
  few 
  punctures 
  on 
  the 
  elytra, 
  and 
  the 
  two 
  discoidal 
  

   striae 
  are 
  indistinct. 
  

  

  Sendai, 
  Nikko, 
  and 
  Sanolie 
  ; 
  four 
  examples. 
  

  

  Oxyporus 
  lonyipes, 
  n. 
  sp. 
  

  

  Rufo-testaceus 
  ; 
  capite, 
  elytrorum 
  abdominisque 
  apicibus 
  nigris 
  ; 
  

  

  antennis 
  pedibusque 
  rlavis. 
  

   Long. 
  9 
  millim. 
  

  

  Antennas 
  rather 
  long, 
  fourth 
  joint 
  longer 
  than 
  broad, 
  tenth 
  

   but 
  little 
  longer 
  than 
  broad. 
  Head 
  elongate, 
  entirely 
  black, 
  

   with 
  a 
  moderately 
  deep 
  fovea 
  on 
  the 
  middle 
  near 
  the 
  front. 
  

   Thorax 
  short, 
  without 
  constrictions 
  or 
  depressions. 
  Scutel- 
  

   lum 
  and 
  elytra 
  reddish 
  yellow, 
  the 
  latter 
  with 
  a 
  large 
  patch 
  

   of 
  black 
  colour 
  behind, 
  with 
  but 
  few 
  punctures. 
  Three 
  termi- 
  

   nal 
  segments 
  of 
  hind 
  body 
  black. 
  Legs 
  elongate, 
  clear 
  yellow.
