  Although 
  very 
  closely 
  allied 
  to 
  T. 
  niveirostris, 
  this 
  is, 
  

   I 
  have 
  no 
  doubt, 
  a 
  distinct 
  species 
  ; 
  the 
  surface 
  is 
  more 
  

   variegate 
  in 
  colour, 
  and 
  the 
  three 
  nodular 
  elevations 
  

   placed 
  in 
  a 
  line 
  on 
  each 
  elytra 
  are 
  very 
  large 
  ; 
  the 
  

   thoracic 
  carina 
  is 
  at 
  each 
  side 
  less 
  deflexed 
  backwards. 
  

   The 
  thorax 
  is 
  separated 
  from 
  the 
  elytra 
  by 
  an 
  angular 
  

   incision 
  on 
  each 
  side, 
  as 
  in 
  T. 
  niveirostris.

  Brevis,

  fusco 
  nigroque 
  variegatus, 
  rostro 
  albidescente, 
  

   tuberculatus 
  ; 
  prothoracis 
  carina 
  praebasali 
  a 
  basi 
  longe 
  remota, 
  

   thorace 
  ab 
  elytris

  separato.

  Antennae 
  rather 
  short 
  and 
  slender, 
  red, 
  with 
  the 
  club 
  darker, 
  the 
  

   first 
  joint 
  of 
  this 
  latter 
  part 
  elongatej 
  second 
  about 
  as 
  long 
  as 
  

   broad, 
  terminal 
  joint 
  rather 
  shorter. 
  Rostrum 
  very 
  short 
  and 
  

   broad, 
  dilated 
  over 
  the 
  insertion 
  of 
  the 
  antennae, 
  whitish 
  ; 
  eyes 
  

   widely 
  separated, 
  but 
  convergent. 
  Thorax 
  short 
  and 
  broad, 
  

   greatly 
  narrowed 
  in 
  front, 
  its 
  carina 
  very 
  conspicuous, 
  placed 
  far 
  

   in 
  front 
  of 
  the 
  base, 
  straight 
  in 
  the 
  middle 
  for 
  the 
  greater 
  part 
  of 
  

   its 
  length, 
  towards 
  the 
  sides 
  very 
  slightly 
  directed 
  backwards, 
  not 
  

   continued 
  forwards 
  along 
  the 
  sides 
  ; 
  behind 
  the 
  carina 
  the 
  thorax 
  

   is 
  greatly 
  narrowed 
  so 
  as 
  to 
  leave 
  a 
  deep 
  excision 
  between 
  it 
  and 
  

   the 
  elytra. 
  Elytra 
  with 
  an 
  elongate 
  subcariniform 
  elevation 
  at 
  

   the 
  base 
  of 
  each 
  near 
  the 
  suture, 
  and 
  behind 
  the 
  middle 
  with 
  a 
  

   smaller 
  elevation 
  ; 
  the 
  general 
  colour 
  is 
  blackish, 
  with 
  the 
  apex, 
  

   the 
  summit 
  of 
  the 
  basal 
  elevations, 
  and 
  a 
  small 
  patch 
  round 
  the 
  

   scutellum, 
  brownish. 
  Pygidium 
  tawny. 
  Legs 
  feeble, 
  variegate. 
  

   Middle 
  coxae

  distant. 
  

  

  This 
  elegant 
  insect 
  is 
  allied 
  to 
  T, 
  niveirostris. 
  Only 
  

   two 
  specimens 
  were 
  met 
  with 
  at 
  Ichiuchi, 
  1st 
  May, 
  1881, 
  

   and 
  Omama, 
  27th
