  Group 
  7. 
  Thoracic 
  carina 
  nearly 
  straight, 
  very 
  close 
  to 
  

   the 
  elytra, 
  forming 
  an 
  acute 
  angle 
  on 
  each 
  side.

  Fuscus, 
  pallido-rufo-signatus, 
  rostro 
  parcius 
  albido-vestitus, 
  

   antennis 
  testaceis, 
  articulis 
  3o 
  — 
  5m 
  clavaque 
  fusco-testaceis 
  ; 
  pro- 
  

   thorace 
  subconico, 
  carina 
  subrecta 
  ad 
  basin 
  approxiniata. 
  Long, 
  

   rostro 
  porrecto 
  4 
  mm. 
  

  

  Antennae 
  slender, 
  with 
  elongate 
  loosely-articulated 
  club, 
  the 
  first 
  

   joint 
  of 
  which 
  is 
  longer 
  than 
  either 
  of 
  the 
  two 
  others, 
  these 
  sub- 
  

   equal 
  in 
  length. 
  Eostrum 
  quadrate, 
  flat, 
  the 
  head 
  sparingly 
  

   clothed 
  with 
  white 
  pubescence, 
  the 
  eyes 
  widely 
  distant 
  behind, 
  

   much 
  convergent 
  in 
  front, 
  but 
  there 
  separated 
  by 
  about 
  half 
  the 
  

   width 
  of 
  the 
  rostrum. 
  Thorax 
  gently 
  narrowed 
  in 
  front, 
  not 
  

   impressed 
  nor 
  deplanate 
  on 
  the 
  disc, 
  largely 
  marked 
  with 
  rather 
  

   indefinite 
  pallid 
  spots 
  ; 
  the 
  carina 
  placed 
  very 
  near 
  the 
  base, 
  

   sharply 
  elevated, 
  straight, 
  joining 
  the 
  lateral 
  margin 
  by 
  a 
  sharply- 
  

   marked 
  rectangle. 
  Elytra 
  destitute 
  of 
  elevations, 
  fuscous, 
  much 
  

   marked 
  with 
  pallid 
  maculae 
  of 
  angular 
  form, 
  and 
  of 
  a 
  faint 
  pink 
  

   tinge. 
  Legs 
  rufescent, 
  vaguely 
  variegate. 
  Prosternum 
  very 
  

   short. 
  Middle 
  coxae 
  widely 
  separated. 
  

  

  I 
  must 
  at 
  present 
  treat 
  this 
  insect 
  as 
  an 
  aberrant 
  

   species 
  of 
  Tropideres 
  ; 
  it 
  differs 
  therefrom 
  by 
  the 
  shorter 
  

   prosternum, 
  and 
  by 
  the 
  thoracic 
  carina 
  ; 
  but 
  as 
  there 
  is 
  

   considerable 
  variety 
  on 
  these 
  points 
  in 
  Tropideres, 
  it 
  

   is 
  better 
  not 
  to 
  separate 
  T. 
  dehilis 
  at 
  present. 
  The 
  

   thoracic 
  carina 
  is 
  similar 
  to 
  that 
  of 
  Cratoparis, 
  except 
  

   that 
  it 
  is 
  slightly 
  separated 
  from 
  the 
  elytra. 
  

  

  Two 
  examples 
  were 
  found 
  at 
  Junsai. 
  From 
  their 
  very- 
  

   mutilated 
  condition 
  it 
  is 
  probable 
  that 
  they 
  were 
  cut 
  

   out 
  of 
  wood. 
  A 
  third 
  specimen, 
  found 
  at 
  Chiuzenji, 
  I 
  

   treat 
  as 
  a 
  variety, 
  though 
  it 
  is 
  rather 
  broader, 
  and 
  

   appears 
  to 
  have 
  the 
  thoracic 
  carina 
  a 
  little 
  more 
  distant 
  

   from 
  the 
  base.
