  Considerably 
  larger, 
  and 
  proportionately 
  broader, 
  tban 
  0. 
  discors; 
  

   the 
  dilated 
  basal 
  j)ortion 
  of 
  the 
  rostrum 
  broader 
  and 
  sliorter 
  ; 
  the 
  

   puncturing 
  both 
  on 
  thorax 
  and 
  elytra 
  less 
  distinct, 
  the 
  punctures 
  

   being 
  smaller 
  and 
  more 
  remote; 
  the 
  interstices 
  of 
  the 
  striaj 
  of 
  the 
  

   elytra 
  broader, 
  and 
  the 
  alternate 
  interstices 
  very 
  distinctly 
  raised, 
  

   and 
  subcarinated. 
  The 
  ridges 
  formed 
  by 
  the 
  fourth 
  and 
  sixth 
  

   interstices 
  are 
  united 
  at 
  some 
  distance 
  from 
  the 
  apex 
  of 
  the 
  elytra; 
  

   the 
  suture, 
  on 
  the 
  hinder 
  half, 
  is 
  also 
  raised, 
  and 
  from 
  the 
  apex 
  

   there 
  is 
  a 
  short 
  ridge 
  which 
  runs 
  obliquely 
  forwards 
  and 
  slightly 
  

   outwards 
  to 
  meet 
  the 
  second 
  interstitial 
  ridge. 
  A 
  series 
  of 
  very 
  

   minute 
  tubercles, 
  each 
  bearing 
  a 
  single 
  pointed 
  scale 
  at 
  its 
  sum- 
  

   mit, 
  is 
  seen 
  on 
  each 
  of 
  the 
  ridges 
  mentioned. 
  The 
  general 
  colour 
  

   is 
  sometimes 
  ashy, 
  sometimes 
  very 
  pale 
  rufous 
  brown. 
  The 
  

   middle 
  pale 
  band 
  on 
  the 
  thorax 
  does 
  not 
  extend 
  quite 
  to 
  the 
  base. 
  

   On 
  the 
  forehead 
  is 
  a 
  small 
  fovea, 
  and 
  on 
  the 
  basal 
  portion 
  of 
  the 
  

   rostrum 
  is 
  a 
  longitudinally-impressed 
  line 
  ; 
  in 
  front 
  of 
  this 
  the 
  

   rostrum 
  is 
  keeled 
  ; 
  in 
  the 
  female 
  the 
  keel 
  is 
  very 
  short, 
  but 
  in 
  

   the 
  male 
  it 
  reaches 
  about 
  half 
  way 
  to 
  the 
  apex 
  of 
  tiie 
  rostrum 
  : 
  

   here 
  the 
  rostrum 
  is 
  rather 
  shorter 
  than 
  in 
  the 
  female, 
  and 
  

   strongly 
  punctured 
  ; 
  the 
  scales 
  extend 
  beyond 
  the 
  point 
  of 
  in- 
  

   sertion 
  of 
  the 
  antenna, 
  whilst 
  in 
  the 
  female 
  scales 
  extend 
  only 
  to 
  

   the 
  points 
  mentioned, 
  and 
  the 
  fore 
  part 
  of 
  the 
  rostrum 
  is 
  nearly 
  

   smooth. 
  

  

  Several 
  specimens 
  of 
  this 
  insect 
  were 
  brought 
  from 
  North 
  

   China 
  by 
  Mr. 
  Fortune, 
  so 
  well 
  known 
  for 
  his 
  travels 
  and 
  re- 
  

   searches 
  in 
  that 
  quarter 
  of 
  the 
  globe. 
  It 
  is 
  after 
  this 
  gentleman 
  

   that 
  I 
  have 
  named 
  the 
  insect.
