  Kashiwagi, 
  16th 
  June, 
  1881 
  ; 
  one 
  specimen. 
  Also 
  two 
  

   examples 
  from 
  the 
  collection 
  made 
  by 
  Mr. 
  Lewis 
  in 
  

   1869. 
  

  

  28. 
  Tropideres 
  difficilis, 
  n. 
  sp. 
  

  

  Niger, 
  tibiis 
  anterioribus 
  et 
  intermediis 
  piceis, 
  antennarum 
  clava 
  

   sat 
  elongata 
  ; 
  prothoracis 
  carina 
  bicurvata, 
  ad 
  basin 
  valde 
  approxi- 
  

   mata. 
  Long. 
  2f 
  mm. 
  

  

  This 
  resembles 
  T. 
  bruchoides 
  and 
  T. 
  imperfectus 
  ; 
  it 
  is 
  dis- 
  

   tinguished 
  from 
  the 
  first 
  by 
  its 
  smaller 
  size, 
  narrower 
  form, 
  and 
  

   the 
  shorter 
  antennae, 
  the 
  eighth 
  joint 
  of 
  which 
  is 
  markedly 
  smaller 
  ; 
  

   at 
  first 
  sight 
  it 
  more 
  resembles 
  T. 
  imjperfectus, 
  but 
  is 
  radically 
  

   distinct 
  from 
  it 
  by 
  the 
  position 
  of 
  the 
  eyes, 
  by 
  the 
  nature 
  of 
  the 
  

   antennal 
  club, 
  and 
  by 
  the 
  thoracic 
  carina 
  being 
  very 
  near 
  to 
  the 
  

   base, 
  so 
  that 
  in 
  some 
  positions 
  it 
  almost 
  touches 
  the 
  elytra. 
  The 
  

   three 
  joints 
  of 
  the 
  club 
  are 
  of 
  subequal 
  length, 
  the 
  tenth 
  about 
  as 
  

   long 
  as 
  broad. 
  The 
  rostrum 
  is 
  very 
  short, 
  very 
  finely 
  sculptured, 
  

   the 
  eyes 
  separated 
  by 
  the 
  greater 
  part 
  of 
  its 
  width. 
  The 
  thoracic 
  

   carina 
  closely 
  follows, 
  in 
  two 
  curves, 
  the 
  outlines 
  of 
  the 
  base 
  of 
  the 
  

   elytra, 
  and 
  its 
  angles 
  project 
  backwards 
  rather 
  than 
  outwards. 
  

   The 
  striation 
  of 
  the 
  elytra 
  is 
  coarse 
  even 
  at 
  the 
  base.

  Xylinades 
  japonicus, 
  n. 
  sp. 
  

   Minor, 
  fulvo 
  fascoque 
  variegatus, 
  pedibus 
  rufis, 
  antennis 
  piceis 
  ; 
  

   prothorace 
  tuberculato-rugoso, 
  carina 
  prsebasilari 
  curvata 
  ; 
  elytris 
  

   profunde, 
  subtiliter 
  striatis, 
  striis 
  subtiliter 
  tuberculatis. 
  Long, 
  

   cimique 
  rostro 
  10 
  mm. 
  

  

  Antennae 
  short, 
  the 
  terminal 
  joint 
  compressed, 
  acuminate 
  in 
  one 
  

   direction, 
  covered 
  with 
  a 
  pallid 
  silky 
  pubescence 
  ; 
  the 
  penultimate 
  

   joint 
  also 
  silky, 
  strongly 
  transverse, 
  the 
  basal 
  joint 
  of 
  the 
  club 
  

   twice 
  as 
  long 
  as 
  the 
  penultimate 
  joint, 
  dark 
  in 
  colour, 
  hke 
  the 
  rest 
  

   of 
  the 
  antennae. 
  Head 
  with 
  a 
  deep 
  longitudinal 
  impression 
  along 
  

   the 
  middle, 
  this 
  impression 
  divided 
  behind 
  into 
  two 
  by 
  a 
  broad 
  

   polished 
  elevation. 
  Thorax 
  about 
  as 
  long 
  as 
  broad, 
  greatest 
  width 
  

   a 
  little 
  in 
  front 
  of 
  the 
  middle, 
  thence 
  a 
  good 
  deal 
  narrowed 
  behind 
  

   close 
  to 
  the 
  front 
  abruptly 
  narrowed; 
  the 
  surface 
  covered 
  with 
  

   tubercular 
  rugosities 
  ; 
  the 
  prsebasal 
  carina 
  not 
  in 
  the 
  least 
  angu- 
  

   late 
  in 
  the 
  middle. 
  Elytra 
  tawny, 
  with 
  some 
  dark 
  marks 
  ; 
  these 
  

   are 
  variable, 
  the 
  most 
  conspicuous 
  being 
  a 
  large 
  one 
  on 
  each 
  side 
  

   just 
  behind 
  the 
  middle, 
  extending 
  inwards 
  towards 
  the 
  suture, 
  so 
  

   that 
  the 
  two 
  almost 
  connect 
  at 
  the 
  suture 
  ; 
  the 
  stride 
  very 
  fine, 
  and 
  

   tubercles 
  in 
  them 
  small.
