  Though 
  closely 
  allied 
  to 
  G. 
  densipenne, 
  this 
  is 
  a 
  narrower 
  

   insect, 
  readily 
  distinguished 
  by 
  the 
  narrower 
  head, 
  more 
  

   sculptured 
  in 
  front, 
  and 
  the 
  more 
  shining 
  wing-cases.

  Nigrum 
  : 
  antennis 
  pedibusque 
  testaceis 
  ; 
  elytris 
  thorace 
  paulo 
  lon- 
  

  

  gioribus, 
  densissiine 
  ruguluso-punctatis. 
  

   Long. 
  10 
  millim. 
  

  

  Antennae 
  unicolorous, 
  yellow. 
  Head 
  elongate 
  and 
  narrow, 
  

   a 
  little 
  narrower 
  than 
  the 
  thorax, 
  distinctly 
  narrower 
  than 
  

   the 
  elytra, 
  densely 
  and 
  coarsely 
  punctured, 
  the 
  punctuation 
  

   scanty 
  in 
  front, 
  the 
  surface 
  shining 
  and 
  very 
  little 
  sculptured 
  

   between 
  the 
  antennal 
  elevations. 
  Thorax 
  elongate 
  and 
  nar- 
  

   row, 
  slightly 
  narrower 
  in 
  front, 
  very 
  shining, 
  black, 
  coarsely

  smooth. 
  

   Elytra 
  slightly 
  longer 
  than 
  the 
  thorax, 
  dull, 
  densely 
  punc- 
  

   tured, 
  the 
  punctures 
  confluent, 
  so 
  as 
  to 
  give 
  rise 
  to 
  a 
  rugulose 
  

   appearance 
  ; 
  the 
  line 
  on 
  the 
  inflexed 
  side 
  present, 
  but 
  fine. 
  

   Male 
  with 
  a 
  deep 
  excision 
  of 
  the 
  last 
  ventral 
  segment. 
  

  

  Closely 
  allied 
  to 
  C. 
  japonicum, 
  but 
  readily 
  distinguished 
  

   by 
  the 
  longer 
  elytra 
  and 
  narrower 
  head.
