   This 
  genus 
  is 
  near 
  Phyllubius 
  in 
  its 
  general 
  characters 
  ; 
  the 
  head 
  

   and 
  thorax 
  are 
  proportionately 
  smaller, 
  the 
  elytra 
  more 
  elongated, 
  

   less 
  convex, 
  and 
  each 
  elytron 
  is 
  distinctly 
  rounded 
  at 
  the 
  apex 
  ; 
  

   the 
  rostrum 
  is 
  shorter 
  and 
  narrower, 
  and 
  the 
  antennal 
  groove 
  is 
  

   differently 
  formed 
  — 
  it 
  is 
  represented 
  by 
  a 
  small 
  and 
  short 
  curved 
  

   fovea 
  placed 
  towards 
  the 
  apex 
  of 
  the 
  rostrum 
  ; 
  the 
  fore 
  part 
  of 
  the 
  

   fovea 
  opens 
  outwards, 
  and 
  the 
  hinder 
  part 
  is 
  curved 
  inwards, 
  and 
  

   forms 
  a 
  notch 
  on 
  the 
  upper 
  surface 
  of 
  the 
  rostrum, 
  and 
  the 
  space 
  

   between 
  the 
  notches 
  entering 
  from 
  opposite 
  sides 
  of 
  the 
  rostrum 
  

   is 
  much 
  contracted. 
  On 
  the 
  upper 
  surface 
  of 
  the 
  terminal 
  por- 
  

   tion 
  of 
  the 
  rostrum 
  is 
  a 
  slightly 
  raised 
  plate, 
  nearly 
  of 
  a 
  quadrate 
  

   form, 
  the 
  posterior 
  angles 
  of 
  which 
  extend 
  partly 
  over 
  the 
  an- 
  

   tennal 
  foveae. 
  The 
  eyes 
  are 
  less 
  prominent 
  than 
  in 
  Phyllobius, 
  

   and 
  the 
  claws 
  are 
  larger 
  and 
  less 
  diverging. 
  The 
  antennae 
  scarcely 
  

   differ.

  The 
  outline 
  of 
  the 
  head 
  is 
  continuous 
  with 
  that 
  of 
  the 
  rostrum 
  

   both 
  above 
  and 
  at 
  the 
  sides, 
  in 
  the 
  latter 
  interrupted 
  only 
  by 
  the 
  

   eyes, 
  which 
  are 
  of 
  a 
  short 
  oval 
  form, 
  very 
  little 
  convex, 
  and 
  placed 
  

   longitudinally. 
  The 
  thorax 
  is 
  very 
  small 
  in 
  proportion 
  to 
  the 
  

   elytra, 
  about 
  equal 
  in 
  length 
  and 
  breadth 
  and 
  nearly 
  cylindrical, 
  

   but 
  with 
  the 
  middle 
  part 
  somewhat 
  swollen. 
  The 
  elytra 
  are 
  

   ample, 
  much 
  elongated, 
  about 
  four 
  times 
  the 
  length 
  of 
  the 
  thorax, 
  

   have 
  the 
  humeral 
  angles 
  prominent, 
  almost 
  in 
  the 
  form 
  of 
  right 
  

   angles, 
  the 
  angle 
  being 
  slightly 
  rounded 
  off'; 
  they 
  gradually 
  in- 
  

   crease 
  in 
  width 
  till 
  they 
  have 
  attained 
  their 
  maximum 
  diameter, 
  

   at 
  a 
  point 
  considerably 
  behind 
  the 
  middle, 
  and 
  then 
  decrease 
  

   again 
  with 
  a 
  gentle 
  convex 
  curve 
  towards 
  the 
  apex, 
  where 
  each 
  

   elytron 
  is 
  rather 
  obtusely 
  rounded. 
  The 
  green 
  scales 
  which 
  cover 
  

   the 
  upper 
  parts 
  have 
  a 
  silky, 
  metallic 
  lustre. 
  

  

  Specimens 
  of 
  this 
  insect 
  will 
  be 
  found 
  in 
  the 
  collection 
  of 
  the 
  

   British 
  Museum. 
  Of 
  course, 
  considerable 
  interest 
  attaches 
  itself
