  Four 
  new 
  species 
  of 
  this 
  genus 
  are 
  described,

  these 
  are 
  

   placed

  two 
  sections.

  P. 
  Chevrolatii, 
  which 
  is 
  of 
  an 
  elongate-ovate 
  form, 
  has 
  the 
  thorax 
  attenuated 
  and 
  

   two-pointed 
  in 
  front, 
  and 
  produced 
  considerably 
  beyond 
  the 
  head,

  a 
  short 
  keel 
  in 
  

   the 
  middle 
  of 
  the 
  dorsal 
  surface, 
  and 
  an 
  obtuse 
  tubercle 
  on 
  each 
  side 
  of 
  this 
  keel 
  : 
  

   small

  the 
  surface 
  of

  two 
  

   near 
  the 
  shoulder: 
  the 
  apex 
  is 
  produced 
  into 
  two 
  conical 
  tubercles, 
  one 
  belonging 
  to 
  

   each 
  elytron.

  besides 
  a 
  transverse 
  irregular 
  elevation 
  at 
  the 
  base; 
  the 
  apex 
  produced 
  

   into 
  a 
  large 
  tubercle,
