  This

  This

  closely 
  allied 
  to

  is 
  a 
  much 
  more 
  

   slender 
  and 
  parallel 
  insect, 
  and 
  differs 
  as 
  follows 
  : 
  — 
  the 
  head 
  

   is 
  almost 
  as 
  broad 
  as 
  the 
  elytra, 
  suboblong; 
  the 
  thorax 
  is 
  

   piceous 
  ; 
  the 
  elytra 
  are 
  only 
  about 
  as 
  long 
  as 
  the 
  thorax 
  and 
  

   are 
  more 
  sparingly 
  punctured, 
  and 
  have 
  a 
  larger 
  yellow 
  apical 
  

   spot.
