  Long. 
  4 
  millim. 
  

  

  Platysoma, 
  scitulum 
  is 
  remarkable 
  in 
  having 
  the 
  thoracic 
  

   stria 
  interrupted 
  behind 
  the 
  eyes, 
  with 
  the 
  median 
  portion 
  

   hamate 
  at 
  either 
  end. 
  The 
  three 
  abbreviated 
  stria3 
  of 
  the 
  

   elytra 
  are 
  feebly 
  impressed 
  and 
  are 
  placed 
  before 
  the 
  apex, 
  

   the 
  middle 
  one 
  being 
  the 
  shortest 
  and 
  most 
  faint 
  and 
  the 
  

   sutural 
  one 
  in 
  front 
  of 
  the 
  others. 
  The 
  propygidium 
  is 
  irre- 
  

   gularly 
  punctured, 
  the 
  punctures 
  inclining 
  to 
  ocellation, 
  and 
  

   some 
  are 
  deeper 
  anteriorly 
  than 
  behind. 
  The 
  species 
  may 
  be 
  

   inserted 
  in 
  the 
  catalogue 
  near 
  P. 
  paugami, 
  Mars.

  Eblisia, 
  no 
  v. 
  gen. 
  

  

  This 
  genus 
  is 
  proposed 
  to 
  receive 
  Phelister 
  lunaticus, 
  

   Mars., 
  ard 
  its 
  allies 
  celebius, 
  speculipygus, 
  and 
  convexa 
  — 
  

   species 
  which 
  have 
  no 
  frontal 
  depression 
  such 
  as 
  would 
  

   authorize 
  their 
  inclusion 
  in 
  Platysoma, 
  and 
  yet 
  at 
  the 
  same 
  time 
  

   the 
  mesosternum 
  is 
  emarginate 
  in 
  front, 
  a 
  salient 
  character 
  

   which 
  must 
  exclude 
  them 
  from 
  Phelister. 
  The 
  type 
  of 
  Phe- 
  

   lister 
  is 
  venustus, 
  Mars., 
  an 
  insect 
  which 
  has 
  the 
  mesosternum 
  

   produced 
  in 
  trout, 
  and 
  the 
  generic 
  character 
  " 
  mesosternum 
  

   bisinuatum 
  " 
  is 
  conspicuous, 
  But 
  in 
  lunaticus 
  the 
  prosternum 
  

   corresponds 
  with 
  that 
  in 
  Platysoma, 
  inasmuch 
  as 
  one 
  of 
  the 
  

   essential 
  characters 
  of 
  the 
  genus 
  is 
  " 
  prosternum 
  compressum, 
  

   basi 
  rotundatuui 
  in 
  mesosterno 
  receptum." 
  The 
  genus 
  Platy- 
  

   soma 
  at 
  present 
  contains 
  some 
  species 
  which 
  1 
  think 
  must 
  

   ultimately 
  be 
  detached 
  from 
  it 
  ; 
  1 
  speak 
  of 
  species 
  such 
  as 
  

   decemstr 
  latum, 
  Motsch.,and 
  exiguum, 
  Lewis; 
  but 
  1 
  think 
  these 
  

   may 
  be 
  assigned 
  at 
  present 
  to 
  the 
  genus 
  Nicotikis, 
  Mars., 
  

   suggested 
  for 
  Platysoma 
  incisipygus 
  (Bull. 
  fcsoc. 
  Ent. 
  Fr. 
  (6)
