  Mr. 
  G. 
  R. 
  Waterhouse's 
  Descriptions 
  of 
  

  

  granules 
  are 
  seen 
  on 
  the 
  hinder 
  half 
  of 
  the 
  thorax 
  ; 
  the 
  sides 
  are 
  

   rounded, 
  have 
  an 
  uneven 
  outline 
  on 
  the 
  hinder 
  half, 
  and 
  a 
  distinct 
  

   notch 
  in 
  the 
  middle 
  : 
  where 
  they 
  join 
  the 
  anterior 
  lobe, 
  which 
  pro- 
  

   jects 
  over 
  the 
  head, 
  they 
  are 
  considerably 
  contracted 
  ; 
  the 
  sides 
  

   of 
  the 
  lobe 
  are 
  straight, 
  converging 
  anteriorly, 
  and 
  the 
  apex 
  is 
  

   notched. 
  Elytra 
  less 
  than 
  twice 
  the 
  length 
  of 
  the 
  thorax, 
  and 
  

   rather 
  broader 
  and 
  strongly 
  convex 
  in 
  the 
  middle; 
  two 
  rows 
  of 
  

   very 
  large 
  shallow 
  fovese 
  are 
  seen 
  on 
  the 
  sides, 
  and 
  on 
  other 
  parts 
  

   are 
  smaller 
  depressions, 
  but 
  disposed 
  without 
  order, 
  the 
  whole 
  

   upper 
  surface 
  being 
  very 
  uneven. 
  Granules 
  are 
  sparingly 
  scattered 
  

   over 
  the 
  surface, 
  and 
  each 
  elytron 
  has 
  five 
  large 
  rounded 
  rugose 
  

   tubercles 
  ; 
  three 
  in 
  a 
  line 
  at 
  a 
  little 
  distance 
  from 
  the 
  suture, 
  the 
  

   middle 
  tubercle 
  being 
  placed 
  about 
  halfway 
  between 
  the 
  extre- 
  

   mities 
  of 
  the 
  elytra, 
  the 
  foremost 
  about 
  midway 
  between 
  the 
  

   middle 
  one 
  and 
  the 
  base 
  of 
  the 
  elytra, 
  and 
  the 
  hindermost 
  

   very 
  little 
  more 
  removed 
  from 
  the 
  middle 
  tubercle 
  than 
  that 
  is 
  

   from 
  the 
  first; 
  the 
  remaining 
  two 
  large 
  tubercles 
  are 
  external 
  

   to 
  the 
  three 
  noticed, 
  not 
  far 
  removed, 
  and 
  nearly 
  opposite 
  their 
  

   interspaces 
  : 
  besides 
  these 
  there 
  is 
  a 
  small 
  tubercle 
  near 
  the 
  

   shoulder, 
  and 
  an 
  oblong 
  tubercle 
  behind 
  this 
  near 
  the 
  middle 
  of 
  

   the 
  lateral 
  portion 
  of 
  the 
  elytra. 
  Each 
  elytron 
  has 
  an 
  obtuse 
  

   transverse 
  ridge 
  at 
  the 
  base, 
  which 
  extends 
  from 
  the 
  suture 
  nearly 
  

   to 
  the 
  shoulder, 
  becoming 
  broader 
  externally. 
  The 
  apical 
  pro- 
  

   cesses 
  are 
  larger 
  and 
  more 
  produced 
  than 
  in 
  P. 
  Chevrolalii, 
  and 
  

   have 
  a 
  nearly 
  triangular 
  base. 
  The 
  whole 
  of 
  the 
  upper 
  parts 
  are 
  

   covered 
  with 
  minute 
  brown 
  scales, 
  but 
  these 
  do 
  not 
  quite 
  hide 
  

   the 
  surface; 
  and, 
  mixed 
  with 
  thetn, 
  are 
  scattered 
  large 
  scales; 
  

   on 
  the 
  summits 
  of 
  the 
  tubercles 
  there 
  are 
  large 
  scales, 
  and 
  on 
  the 
  

   apex 
  of 
  the 
  thorax 
  the 
  scales 
  are 
  sub-setiform. 
  The 
  legs 
  are 
  

   covered 
  with 
  brown 
  setiform 
  scales, 
  with 
  an 
  admixture 
  of 
  small 
  

   black 
  setae 
  ; 
  the 
  femora 
  are 
  edentate. 
  

  

  I 
  have 
  named 
  this 
  species 
  after 
  M, 
  Jekel 
  of 
  Paris, 
  so 
  celebrated 
  

   for 
  his 
  knowledge 
  of 
  the 
  Curcuiwnides, 
  and 
  to 
  whom 
  I 
  am 
  in- 
  

   debted 
  for 
  much 
  information 
  on 
  this 
  branch 
  of 
  Entomology.
