  Waterhouse's 
  Descriptions 
  of 
  

  

  and 
  in 
  the 
  middle 
  is 
  a 
  longitudinal 
  groove. 
  On 
  the 
  lower 
  part 
  of 
  

   the 
  sides 
  of 
  the 
  thorax 
  the 
  scales 
  are 
  more 
  dense, 
  and 
  of 
  a 
  more 
  

   decided 
  yellow 
  colour. 
  Scutellum 
  transverse; 
  elytra 
  at 
  the 
  base 
  

   equal 
  in 
  width 
  to 
  the 
  part 
  of 
  the 
  thorax 
  which 
  they 
  join, 
  they 
  

   then 
  swell 
  out 
  very 
  gradually, 
  and 
  assume 
  an 
  elongate 
  oval 
  form 
  ; 
  

   each 
  elytron 
  is 
  slightly 
  produced 
  at 
  the 
  apex; 
  the 
  upper 
  surface 
  

   is 
  moderately 
  convex 
  ; 
  the 
  punctures 
  of 
  the 
  striae 
  remote, 
  and 
  of 
  

   moderate 
  size 
  ; 
  interstices 
  flat, 
  or 
  very 
  nearly 
  so, 
  and 
  very 
  in- 
  

   distinctly 
  setose 
  : 
  the 
  third 
  and 
  fifth 
  interstices 
  are 
  rather 
  broader 
  

   than 
  the 
  others. 
  The 
  tibiae 
  are 
  but 
  indistinctly 
  denticulated 
  

   within. 
  The 
  terminal 
  segment 
  of 
  the 
  abdomen 
  is 
  destitute 
  of 
  

   scales 
  ; 
  the 
  femora 
  dusky 
  at 
  the 
  apex. 
  The 
  anterior 
  coxae 
  are 
  

   separated 
  as 
  in 
  L. 
  warginatus. 
  

  

  I 
  have 
  named 
  this 
  species 
  in 
  honour 
  of 
  Mr. 
  Walton, 
  who 
  has 
  

   determined 
  with 
  so 
  much 
  care 
  the 
  British 
  species 
  of 
  Ciirculio- 
  

   nides.

   This 
  genus 
  1 
  am 
  inclined 
  to 
  place 
  near 
  to 
  Prostomus 
  ; 
  the 
  form 
  

   of 
  the 
  head 
  is 
  nearly 
  the 
  same 
  as 
  in 
  that 
  genus, 
  but 
  the 
  eyes 
  are 
  

   less 
  prominent, 
  and 
  rather 
  more 
  remote 
  from 
  the 
  thorax 
  ; 
  the 
  ros- 
  

   trum 
  has 
  the 
  same 
  general 
  proportions, 
  but 
  wants 
  the 
  two 
  grooves 
  

   and 
  three 
  longitudinal 
  ridges 
  ; 
  the 
  antennal 
  groove 
  takes 
  the 
  same 
  

   direction, 
  and 
  terminates 
  at 
  a 
  little 
  distance 
  below 
  the 
  eye 
  ; 
  the 
  

   joints 
  of 
  the 
  antennae 
  are 
  rather 
  shorter 
  ; 
  the 
  thorax 
  presents 
  

   nearly 
  the 
  same 
  outline, 
  but 
  is 
  rather 
  less 
  convex, 
  as 
  are 
  also 
  the 
  

   elytra, 
  which 
  differ, 
  moreover, 
  in 
  not 
  having 
  the 
  humeral 
  angle 
  

   produced. 
  The 
  fore 
  legs 
  are 
  longer 
  than 
  the 
  rest 
  ;
