  Much 
  praise 
  is 
  due 
  to 
  Mr. 
  Fortjine 
  for 
  the 
  attention 
  he 
  was 
  

   able 
  to 
  give 
  to 
  the 
  subject 
  of 
  insects 
  during 
  his 
  interesting 
  journey 
  

   after 
  plants 
  and 
  seeds 
  of 
  the 
  tea 
  shrub, 
  for 
  it 
  must 
  be 
  borne 
  in 
  

   mind, 
  that 
  Entomology 
  formed 
  no 
  portion 
  of 
  his 
  arduous 
  duties, 
  

   and 
  it 
  was 
  only 
  a 
  desire 
  to 
  make 
  himself 
  generally 
  useful 
  to 
  the 
  

   scientific 
  world 
  which 
  induced 
  him 
  to 
  collect 
  insects, 
  he 
  well 
  

   knowing 
  how 
  interesting 
  they 
  would 
  prove 
  to 
  the 
  Entomologist. 
  

  

  Mr. 
  Fortune 
  has 
  kindly 
  furnished 
  me 
  with 
  a 
  short 
  account 
  of 
  

   the 
  district 
  from 
  whence 
  the 
  greater 
  portion 
  of 
  the 
  specimens 
  were 
  

   obtained. 
  He 
  informs 
  me, 
  that 
  this 
  district 
  is 
  included 
  between 
  the 
  

   parallels 
  of 
  20° 
  and 
  32° 
  north 
  latitude, 
  on 
  the 
  east 
  coast 
  of 
  China. 
  

   Some 
  were 
  taken 
  on 
  the 
  Island 
  of 
  Chusan 
  and 
  on 
  other 
  members 
  of 
  

   the 
  Chusan 
  Archipelago, 
  but 
  these 
  form 
  only 
  a 
  very 
  small 
  portion 
  of 
  

   the 
  whole 
  collection. 
  Looking 
  to 
  a 
  map 
  of 
  China, 
  the 
  country 
  which 
  

   he 
  visited 
  will 
  be 
  perceived 
  at 
  once. 
  From 
  the 
  Islands 
  of 
  Chusan 
  his 
  

   researches 
  were 
  extended 
  westward 
  to 
  116° 
  east 
  longitude, 
  that 
  is 
  to 
  

   say, 
  from 
  about 
  122° 
  to 
  116"; 
  and 
  hence 
  it 
  will 
  be 
  evident 
  that 
  he 
  

   penetrated 
  some 
  considerable 
  distance 
  into 
  the 
  interior 
  of 
  the 
  coun- 
  

   try. 
  With 
  the 
  exception 
  of 
  the 
  great 
  plain 
  of 
  Shanghai, 
  the 
  country 
  

   visited 
  is 
  of 
  a 
  mountainous 
  character, 
  running 
  into 
  elevations 
  from 
  

   1 
  000 
  to 
  2000 
  feet 
  in 
  height. 
  The 
  chief 
  of 
  the 
  larger 
  and 
  more 
  

   interesting 
  species 
  were 
  obtained 
  from 
  this 
  elevated 
  district. 
  Clay, 
  

   slate, 
  and 
  granite, 
  are 
  the 
  most 
  abundant 
  rocks 
  in 
  this 
  hill 
  country. 
  

   The 
  soil 
  is 
  generally 
  of 
  a 
  reddish 
  colour, 
  composed 
  of 
  clay, 
  sand, 
  

   and 
  vegetable 
  matter, 
  and 
  much 
  mixed 
  with 
  particles 
  of 
  the 
  rocks 
  

   of 
  the 
  country. 
  The 
  vegetation 
  of 
  the 
  district 
  appears 
  to 
  be 
  lux- 
  

   uriant 
  and 
  abundant. 
  

  

  Turning 
  now 
  to 
  the 
  specimens 
  which 
  Mr. 
  Fortune 
  collected 
  — 
  

   they 
  consisted 
  of 
  insects 
  of 
  all 
  orders, 
  among 
  which 
  were 
  a 
  con- 
  

   siderable 
  number 
  of 
  w'ell-known 
  forms, 
  combined 
  with 
  others 
  of 
  

   very 
  great 
  rarity, 
  and 
  a 
  large 
  number 
  of 
  altogether 
  new 
  species. 
  

   Of 
  the 
  latter, 
  those 
  described 
  hereafter 
  will 
  fully 
  establish 
  the 
  

   value 
  of 
  Mr. 
  Fortune's 
  researches; 
  and 
  I 
  may 
  mention, 
  among 
  

   insects 
  of 
  great 
  rarity 
  and 
  interest, 
  the 
  following 
  Coleoptera 
  as 
  

   particularly 
  worthy 
  of 
  notice. 
  

  

  Dicronocephalus 
  WaUkhii 
  $ 
  , 
  which 
  had 
  only 
  previously 
  been 
  

   obtained 
  from 
  Nepaul. 
  A 
  single 
  $ 
  specimen 
  was 
  procured, 
  and 
  

   tlys 
  has 
  all 
  the 
  characters 
  of 
  the 
  Indian 
  examples, 
  except 
  that 
  the 
  

   ^orns 
  on 
  the 
  clypeus 
  are 
  less 
  elongate, 
  and 
  but 
  little 
  curving 
  

   upwards 
  at 
  the 
  extremity. 
  In 
  this 
  respect 
  the 
  specimen 
  much 
  

   resembles 
  the 
  figure 
  in 
  Gory 
  and 
  Pecheron's 
  monograph 
  of 
  the 
  

   Cctoniadce 
  (pi. 
  26, 
  fig. 
  1). 
  The 
  female' 
  of 
  this 
  interesting 
  and 
  

   remarkable 
  insect 
  is 
  still 
  unknown, 
  and 
  should 
  be 
  carefully 
  sought
