  except 
  that 
  the 
  males 
  have 
  the 
  eyes 
  very 
  approximate 
  in 
  

   front, 
  and 
  a 
  mucro 
  directed 
  inwards 
  on 
  the 
  inner 
  margin 
  

   of 
  the 
  extremity 
  of 
  the 
  middle 
  tibia. 
  I 
  have 
  dissected 
  

   out 
  the 
  copulatory 
  organs 
  of 
  a 
  male 
  example, 
  and 
  they 
  

   leave 
  no 
  doubt 
  that 
  T. 
  jajjonicus 
  is 
  quite 
  distinct 
  from 
  

   T. 
  alhirostris 
  and 
  T. 
  vilis.

  This 
  differs 
  from 
  the 
  following 
  three 
  species 
  by 
  the 
  more 
  elon- 
  

   gate, 
  slender, 
  and 
  less 
  compact 
  club 
  to 
  the 
  antennae, 
  and 
  also 
  by 
  a 
  

   distinct 
  difference 
  in 
  the 
  direction 
  of 
  the 
  prsbasal 
  carina 
  of 
  the 
  

   thorax, 
  as 
  weU 
  as 
  by 
  the 
  eyes 
  being 
  a 
  little 
  more 
  distant. 
  The 
  

   three 
  joints 
  of 
  the 
  club 
  of 
  the 
  antenna 
  are 
  subequal 
  in 
  length, 
  and 
  

   all 
  are 
  slender, 
  each 
  much 
  longer 
  than 
  broad. 
  The 
  thoracic 
  carina 
  

   is 
  widely 
  separated 
  from 
  the 
  base 
  in 
  the 
  middle, 
  but 
  on 
  each 
  side 
  

   becomes 
  slightly 
  more 
  approximate 
  to 
  the 
  base, 
  instead 
  of 
  more 
  

   distant 
  from 
  it 
  as 
  it 
  is 
  in 
  the 
  following 
  species 
  ; 
  there 
  is 
  a 
  large 
  

   quadrate 
  ochraceous 
  mark 
  in 
  front 
  of 
  the 
  scutellum. 
  The 
  elj'tra 
  

   have 
  a 
  very 
  small 
  pallid 
  mark 
  adjacent 
  to 
  the 
  scuteUum, 
  and 
  each, 
  

   just 
  behind 
  the 
  middle 
  near 
  the 
  suture, 
  has 
  a 
  small 
  but 
  conspicuous 
  

   white 
  mark. 
  The 
  legs 
  bear 
  rings 
  of 
  pallid 
  colour", 
  there 
  being 
  two 
  

   such 
  rings 
  on 
  each 
  tibia. 
  

  

  It 
  seems 
  difficult 
  to 
  distinguish 
  the 
  sexes 
  in 
  this 
  

   species 
  ; 
  indeed, 
  I 
  have 
  not 
  detected 
  any 
  certain 
  external 
  

   distinctions 
  : 
  the 
  club 
  of 
  the 
  antennae 
  is 
  more 
  elongate 
  

   in 
  certain 
  examples, 
  but 
  I 
  fancy 
  this 
  is, 
  in 
  T. 
  laxus, 
  not 
  

   a 
  sexual 
  variation. 
  The 
  colour 
  of 
  the 
  pallid 
  clothing 
  of 
  

   the 
  rostrum 
  and 
  head 
  varies 
  considerably, 
  and 
  the 
  small 
  

   pallid 
  marks 
  on 
  the 
  elytra 
  are 
  by 
  no 
  means 
  similar 
  in 
  

   all 
  the 
  examples. 
  

  

  T. 
  laxus 
  was 
  found 
  in 
  small 
  numbers 
  in 
  several 
  

   localities 
  from 
  Yezo, 
  southwards 
  to 
  Yuyama.
