   Two 
  examples. 
  

  

  A 
  distinct 
  species, 
  not 
  closely 
  allied 
  to 
  any 
  hitherto 
  

   described. 
  The 
  outline 
  of 
  the 
  thorax 
  is 
  less 
  semicircular 
  

   than 
  in 
  P. 
  rotundipenjiis, 
  and 
  more 
  nearly 
  resembles 
  

   that 
  of 
  P. 
  sftibangulatus 
  ;, 
  the 
  hind 
  angles, 
  however, 
  are 
  

   less 
  distinctly 
  pronounced 
  than 
  in 
  that 
  species, 
  without 
  

   being 
  broadly 
  rounded 
  off, 
  as 
  in 
  P. 
  rotimdipennis 
  ; 
  the 
  

   sides 
  also 
  are 
  more 
  broadly 
  rounded 
  in 
  the 
  middle, 
  and 
  

   converge 
  more 
  to 
  the 
  base, 
  where 
  the 
  thorax 
  is 
  much 
  

   narrower; 
  the 
  basal 
  impressions 
  are 
  faintly 
  marked. 
  

   The 
  elytra 
  are 
  somewhat 
  elongate-ovate, 
  convex, 
  the 
  

   strise 
  wdde, 
  not 
  sharply 
  impressed, 
  opaque, 
  and 
  without 
  

   distinct 
  punctuation 
  ; 
  the 
  interstices 
  convex, 
  nearly 
  

   equal 
  in 
  width, 
  the 
  8.th 
  without 
  the 
  usual 
  row 
  of 
  punc- 
  

   tures.

  This 
  might 
  be 
  considered 
  merely 
  a 
  local 
  variety 
  of 
  

   S. 
  tcxanus^ 
  but 
  the 
  nearly 
  smooth 
  and 
  polished 
  elj^tra 
  

   give 
  it 
  a 
  distinct 
  facies 
  ; 
  the 
  eyes, 
  too, 
  are 
  decidedly 
  less 
  

   convex, 
  and 
  the 
  head 
  broader 
  behind 
  than 
  in
