  Var. 
  a, 
  capite 
  rostroque 
  sub 
  oculos 
  niveo-tomentosis, 
  elytris 
  

   albido-variegatis. 
  

  

  Var. 
  /3, 
  minus 
  variegatus, 
  rostro 
  capiteque 
  parum 
  tomentosis. 
  

  

  This 
  species 
  is 
  closely 
  allied 
  to 
  the 
  European 
  T. 
  albi- 
  

   rostris, 
  but 
  the 
  club 
  of 
  the 
  antennae 
  is 
  a 
  little 
  longer, 
  

   and 
  the 
  white 
  marks 
  on 
  the 
  posterior 
  part 
  of 
  the 
  elytra 
  

   are 
  small 
  and 
  disconnected, 
  and 
  do 
  not 
  form 
  a 
  large 
  

   common 
  patch 
  as 
  they 
  do 
  in 
  T. 
  albirostris. 
  

  

  I 
  refer 
  to 
  T. 
  (jermanus 
  a 
  series 
  of 
  about 
  a 
  dozen 
  ex- 
  

   amples, 
  but 
  if 
  they 
  are 
  all 
  one 
  species, 
  it 
  is 
  a 
  very 
  variable 
  

   one 
  in 
  colour. 
  The 
  specimens 
  I 
  have 
  treated 
  arbitrarily, 
  

   as 
  the 
  types 
  were 
  found 
  at 
  the 
  Moon 
  Temple, 
  Kobe, 
  and 
  

   at 
  Buno, 
  in 
  the 
  end 
  of 
  August, 
  1881 
  ; 
  these 
  are 
  the 
  

   most 
  different 
  in 
  appearance 
  from 
  T. 
  albirostris. 
  Three 
  

   examples, 
  which 
  I 
  have 
  little 
  doubt 
  are 
  the 
  same 
  species, 
  

   though 
  they 
  differ 
  in 
  the 
  colour 
  of 
  the 
  elytra 
  and 
  their 
  

   markings, 
  were 
  found 
  at 
  Nikko, 
  Yuyama, 
  and 
  Kashiwagi. 
  

   The 
  two 
  very 
  different-looking 
  individuals 
  I 
  have 
  treated 
  

   as 
  var. 
  a 
  were 
  found 
  at 
  Sapporo, 
  and 
  the 
  exponents 
  of 
  

   var. 
  (3 
  at 
  Junsai. 
  

  

  7. 
  Tropideres 
  vilis, 
  n. 
  sp. 
  

   Niger, 
  fere 
  concolor 
  ; 
  antennis 
  brevioribus, 
  clava 
  brevi. 
  Long. 
  

   5 
  mm. 
  

  

  This 
  differs 
  from 
  T. 
  germanus 
  by 
  the 
  smaller, 
  less 
  

   variegate, 
  surface, 
  and 
  by 
  the 
  shorter 
  basal 
  joint 
  to 
  the 
  

   club 
  of 
  the 
  antennae. 
  It 
  scarcely 
  differs 
  in 
  any 
  im- 
  

   portant 
  point 
  from 
  T. 
  albirostris, 
  though 
  the 
  different 
  

   colour 
  of 
  the 
  head, 
  rostrum, 
  and 
  apical 
  part 
  of 
  the 
  

   elytra 
  render 
  them 
  very 
  distinct 
  on 
  superficial 
  in- 
  

   spection. 
  

  

  A 
  few 
  specimens 
  were 
  found 
  in 
  the 
  Island 
  of 
  Yezo, 
  

   Hitoyoshi, 
  and 
  Kashiwagi. 
  

  

  I 
  am 
  by 
  no 
  means 
  sure 
  as 
  to 
  the 
  validity 
  of 
  the 
  dis- 
  

   tinctions 
  between 
  these 
  two 
  Japanese 
  forms 
  and 
  T. 
  albi- 
  

   rostris. 
  I 
  have 
  examined 
  the 
  male 
  organs 
  in 
  them, 
  but 
  

   these 
  do 
  not 
  settle 
  the 
  point, 
  as, 
  though 
  they 
  exhibit 
  

   certain 
  differences, 
  it 
  is 
  quite 
  possible 
  these 
  may 
  not 
  be 
  

   constant, 
  and 
  they 
  are 
  but 
  slight.
