  on 
  the 
  

  

  29. 
  Coelostomus 
  picipes. 
  Figured 
  by 
  Hope 
  (Col. 
  Man. 
  

   ii, 
  1838, 
  t. 
  2, 
  f. 
  6). 
  Nothing 
  further 
  has 
  apparently 
  been 
  

   pubhshed 
  regarding 
  this 
  genus 
  or 
  species, 
  and 
  as 
  both 
  

   names 
  replace 
  later 
  ones, 
  I 
  must 
  go 
  into 
  some 
  detail. 
  

  

  Under 
  the 
  name 
  of 
  Drimostoma 
  striatocolle 
  (Spec. 
  Gen. 
  

   V, 
  1831, 
  747) 
  Dejean 
  described 
  a 
  species 
  from 
  Senegal, 
  and 
  

   identified 
  with 
  it 
  another 
  example 
  he 
  had 
  received 
  from 
  

   the 
  " 
  Indes 
  Orientales." 
  A 
  new 
  species 
  was 
  described 
  by 
  

   Nietner 
  from 
  Ceylon 
  (Ann. 
  and 
  Mag. 
  of 
  Nat. 
  Hist. 
  3, 
  ii, 
  

   1858, 
  178) 
  as 
  Drimostoma 
  ceylanicum, 
  and 
  in 
  the 
  year 
  

   following 
  Motchulsky 
  (Et. 
  Ent.' 
  1859, 
  34, 
  t. 
  1, 
  f. 
  6) 
  described 
  

   a 
  new 
  genus 
  and 
  species 
  under 
  the 
  name 
  of 
  Stomonaxus 
  

   sculptipennis. 
  Two 
  years 
  later 
  Boheman 
  (Eug. 
  Res. 
  Zool. 
  

   Col. 
  1861, 
  13) 
  published 
  his 
  Driynostoma 
  rufipes 
  from 
  China. 
  

   In 
  1872 
  there 
  appeared 
  a 
  memoir 
  by 
  Chaudoir 
  entitled 
  

   " 
  Essai 
  monographique 
  sur 
  les 
  Drimostomides 
  " 
  (Ann. 
  Soc. 
  

   Ent. 
  Belg. 
  xv, 
  1872), 
  in 
  which 
  Stomotiaxus 
  was 
  admitted 
  as 
  

   a 
  genus, 
  and 
  striaticollis 
  Dej. 
  appears 
  (p. 
  13), 
  accompanied 
  

   by 
  the 
  following 
  svnonymy 
  D. 
  ruji'pes 
  Boh., 
  D. 
  marginale 
  

   Walk. 
  (Ann. 
  and 
  "Mag. 
  of 
  Nat. 
  Hist. 
  3, 
  iii, 
  1859, 
  51), 
  

   S. 
  sculpti'pennis 
  ? 
  Motch., 
  and 
  D. 
  ceylanicum 
  Nietn. 
  

   Walker's 
  species, 
  as 
  I 
  shall 
  mention 
  later, 
  belongs 
  to 
  quite 
  

   a 
  different 
  genus. 
  I 
  think 
  very 
  likely 
  S. 
  sculptipennis 
  

   Motch. 
  = 
  D. 
  ceylanicum 
  Nietn., 
  and 
  both 
  may 
  prove 
  to 
  

   be 
  identical 
  wdth 
  D. 
  rvfipes 
  Boh.; 
  I 
  have, 
  however, 
  no 
  

   means 
  at 
  present 
  of 
  determining 
  this. 
  Bates 
  (Trans. 
  Ent. 
  

   Soc. 
  1873, 
  283) 
  records 
  S. 
  striaticollis 
  from 
  Japan, 
  and 
  later 
  

   on 
  from 
  various 
  other 
  Eastern 
  localities. 
  Tchitcherin 
  

   described 
  S. 
  japonicus 
  (Hor. 
  Soc. 
  Ent. 
  Ross, 
  xxxii, 
  1898, 
  

   14) 
  also 
  from 
  Japan, 
  and 
  two 
  years 
  later 
  (I.e. 
  xxxiv, 
  1900, 
  

   262) 
  pubhshed 
  a 
  paper 
  in 
  which 
  he 
  pointed 
  out 
  (1) 
  that 
  

   Bates' 
  Japanese 
  S. 
  striaticollis 
  actually 
  belonged 
  to 
  his 
  

   S. 
  japonicus; 
  (2) 
  that 
  Dejean's 
  S. 
  striaticollis 
  from 
  Senegal 
  

   differed 
  from 
  the 
  Asiatic 
  species, 
  which 
  in 
  his 
  view 
  should 
  

   bear 
  the 
  name 
  S. 
  rufipes 
  Boh. 
  

  

  I 
  find 
  that 
  Boheman's 
  species 
  (though 
  I 
  have 
  not 
  seen 
  

   the 
  type) 
  is 
  identical 
  with 
  Macleay's, 
  so 
  that 
  a 
  further, 
  

   perhaps 
  the 
  final 
  change 
  to 
  be 
  made 
  is 
  the 
  substitution 
  of 
  

   Coelostomus 
  for 
  Stomonaxus 
  and 
  picipes 
  for 
  rufipes. 
  

  

  The 
  species 
  is 
  widely 
  distributed 
  throughout 
  S.E. 
  (Con- 
  

   tinental) 
  Asia, 
  but 
  the 
  type 
  is 
  the 
  only 
  specimen 
  I 
  have 
  

   seen 
  from 
  the 
  Malay 
  Islands. 
  Tchitcherin, 
  however, 
  

   records 
  a 
  local 
  form 
  from 
  Borneo 
  under 
  the 
  name 
  of 
  

   Stomonaxus 
  horneensis 
  (I.e. 
  xxxii, 
  1898, 
  13, 
  and 
  xxxiv, 
  1900,
