  Antennae 
  black, 
  slender, 
  elongate 
  ; 
  club 
  very 
  long, 
  its 
  first 
  joint 
  

   longer 
  than 
  the 
  seventh 
  and 
  eighth 
  together, 
  tenth 
  and 
  eleventh 
  

   joints 
  subequal, 
  each 
  distinctly 
  shorter 
  than 
  the 
  ninth. 
  Eostrom 
  

   short 
  and 
  broad, 
  transversely 
  impressed 
  across 
  the 
  front, 
  dark 
  in 
  

   colour, 
  with 
  some 
  delicate 
  pallid 
  pubescence 
  rear 
  the 
  eyes, 
  most 
  

   distinct 
  at 
  the 
  vertex 
  ; 
  eyes 
  encroaching 
  on 
  the 
  front, 
  but 
  separated 
  

   by 
  half 
  the 
  width 
  of 
  the 
  rostrum. 
  Thorax 
  gently 
  narrowed 
  in 
  

   front, 
  marked 
  with 
  some 
  widely 
  sepai-ated 
  small 
  spots 
  of 
  pallid 
  

   pubescence 
  ; 
  the 
  carina 
  remote 
  from 
  the 
  base, 
  forming 
  two 
  cui-ves, 
  

   with 
  their 
  convexities 
  forwards, 
  which 
  meet 
  in 
  the 
  middle 
  in 
  an 
  

   excessively 
  obtuse 
  angle 
  ; 
  the 
  hind 
  angles 
  prominent, 
  so 
  that 
  an 
  

   incision 
  exists 
  between 
  the 
  bases 
  of 
  the 
  thorax 
  and 
  elytra 
  on 
  each 
  

   side. 
  Elytra

  Two 
  specimens. 
  

  

  This 
  and 
  the 
  following 
  species 
  are 
  allied 
  to 
  the 
  

   European 
  T.

  This 
  differs 
  from 
  T. 
  guttifer 
  in 
  being 
  smaller 
  and 
  uni- 
  

   formly 
  covered 
  with 
  pallid 
  pubescence 
  ; 
  the 
  ninth 
  joint 
  

   of 
  the 
  antenna 
  is 
  but 
  little 
  longer 
  than 
  the 
  seventh 
  ; 
  this 
  

   latter 
  distinction 
  may 
  be 
  sexual, 
  as 
  the 
  unique 
  example 
  

   of 
  T. 
  concolor 
  is 
  a 
  male, 
  while 
  the 
  two 
  specimens 
  of 
  T. 
  

   guttifer 
  are 
  females. 
  The 
  middle 
  coxse 
  are 
  rather 
  less 
  

   widely 
  separated 
  in 
  T. 
  concolor 
  ; 
  the 
  thoracic 
  carina 
  is 
  

   similar.
