  at 
  Nagasaki, 
  Kiga, 
  and 
  Higo 
  in 
  single 
  

   examples. 
  

  

  3. 
  Tropideres 
  latirostris, 
  n. 
  sp. 
  

  

  Niger, 
  ochraceo-variegatus, 
  rostro 
  in 
  faciem 
  externam 
  capiteque 
  

   sub 
  oculos 
  griseo-vestitis 
  ; 
  antennarum 
  clava 
  valde 
  elongata, 
  

   articulis 
  inaequalibus, 
  intermedio 
  transverso. 
  Long, 
  rostro 
  deflexo 
  

   8—9 
  mm. 
  

  

  This 
  Tropideres 
  may 
  be 
  at 
  once 
  identified 
  by 
  the 
  peculiar 
  con- 
  

   struction 
  of 
  the 
  chib 
  of 
  the 
  antennae, 
  the 
  first 
  and 
  third 
  joints 
  of 
  

   this 
  part 
  being 
  very 
  elongate, 
  while 
  the 
  intermediate 
  one 
  remains 
  

   quite 
  short 
  ; 
  the 
  intermediate 
  joints 
  are 
  slender, 
  each 
  reddish 
  in 
  

   colour, 
  marked 
  with 
  fuscous. 
  The 
  rostru.m 
  is 
  very 
  broad, 
  covered 
  

   with 
  very 
  minute 
  cinereous 
  or 
  griseous 
  tomentum, 
  this 
  colour 
  

   extending 
  between 
  the 
  eyes, 
  while 
  below 
  each 
  eye 
  there 
  is 
  a 
  patch 
  

   of 
  similar 
  colour. 
  The 
  thorax 
  is 
  not 
  coarsely 
  sculptured, 
  and 
  

   bears 
  several 
  small 
  obscure 
  spots 
  of 
  an 
  ochraceous 
  colour. 
  The 
  

   elytra 
  are 
  much 
  variegate, 
  in 
  a 
  complex 
  manner, 
  with 
  a 
  similar 
  

   colour, 
  and 
  the 
  tibiae 
  and 
  tarsi 
  are 
  marked 
  with 
  pallid 
  rings. 
  The 
  

   male 
  has 
  a 
  well-marked 
  mucro 
  at 
  the 
  extremity 
  of 
  the 
  inner 
  face 
  

   of 
  the 
  middle 
  tibia, 
  and 
  the 
  eyes 
  in 
  front 
  are 
  separated 
  by 
  a 
  smaller 
  

   interval 
  than 
  they 
  are 
  in 
  the 
  female.

  Oyayama 
  at 
  the 
  end 
  of 
  

   March 
  ; 
  Kurigahara, 
  5th 
  of 
  August. 
  One 
  specimen 
  

   marked 
  as 
  being 
  found 
  under 
  bark 
  of 
  pine. 
  

  

  The 
  structure 
  of 
  the 
  club 
  of 
  the 
  antennae 
  is 
  similar 
  to 
  

   what 
  exists 
  in 
  Acorynus.

  Tropideres 
  japonicus.

  japonicus,

  Ent. 
  Belg.,

  Iv. 
  

  

  This 
  species 
  as 
  yet 
  has 
  been 
  found 
  only 
  by 
  Hiller 
  at 
  

   Tokio. 
  I 
  do 
  not 
  know 
  why 
  it 
  was 
  placed 
  in 
  Litocerus, 
  as 
  

   it 
  is 
  extremely 
  closely 
  allied 
  to 
  T. 
  albirostris, 
  the 
  type 
  of 
  

   the 
  genus 
  Tropideres 
  ; 
  it 
  may, 
  however, 
  be 
  distinguished 
  

   from 
  it, 
  as 
  well 
  as 
  from 
  the 
  following 
  species, 
  by 
  the 
  

   antennae 
  being 
  rather 
  more 
  slender 
  and 
  pallid 
  in 
  colour, 
  

   with 
  a 
  rather 
  longer 
  basal 
  joint 
  to 
  the 
  club, 
  and 
  by 
  the 
  

   upper 
  surface 
  being 
  clothed 
  with 
  a 
  very 
  delicate 
  more 
  

   fuscous 
  tomentum, 
  which 
  is 
  very 
  indefinitely 
  variegate. 
  

   I 
  have 
  been 
  able 
  to 
  inspect 
  a 
  small 
  series 
  of 
  the 
  examples 
  

   found 
  by 
  Mr. 
  Hiller, 
  and 
  I 
  cannot 
  see 
  any 
  variation,
