  shown. 
  As 
  regards 
  the 
  cerci, 
  the 
  difference 
  is 
  also 
  somewhat 
  doubtful, 
  as 
  the 
  type 
  

   of 
  H. 
  tonkinensis 
  has 
  only 
  the 
  right 
  cercus 
  left, 
  and 
  its 
  shape 
  may 
  be 
  due 
  to 
  malfor- 
  

   mation 
  of 
  the 
  inner 
  tooth 
  following 
  some 
  injury 
  to 
  it 
  during 
  moulting. 
  Since, 
  however, 
  

   no 
  specimens 
  of 
  H. 
  banian 
  are 
  known 
  from 
  Tonkin, 
  or 
  from 
  China 
  in 
  general, 
  I 
  prefer 
  

   to 
  keep 
  H. 
  tonkinensis 
  separate 
  until 
  further 
  material 
  is 
  available. 
  

   The 
  type 
  is 
  from 
  Hanoi, 
  Tonkin.

  This 
  species 
  and 
  the 
  very 
  closely 
  related 
  H. 
  oryzivorus 
  form 
  a 
  somewhat 
  aberrant 
  

   group 
  within 
  the 
  genus, 
  but 
  I 
  see 
  no 
  reason 
  for 
  separating 
  them 
  off, 
  as 
  the 
  principal 
  

   characters 
  which 
  may 
  be 
  considered 
  of 
  generic 
  value 
  are 
  sufficiently 
  uniform 
  throughout 
  

   all 
  species 
  included 
  in 
  it. 
  

  

  H. 
  daganensis 
  is 
  remarkable 
  for 
  its 
  very 
  pale 
  greenish 
  coloration, 
  with 
  the 
  hind 
  

   femora 
  straw-coloured 
  on 
  the 
  outer 
  side 
  and 
  more 
  or 
  less 
  reddish 
  below 
  ; 
  hind 
  tibiae 
  

   pale 
  blue 
  ; 
  black 
  marks 
  on 
  the 
  lateral 
  lobes 
  of 
  pronotum 
  very 
  sharp, 
  the 
  first 
  and 
  

   third 
  sulcus 
  being 
  connected 
  by 
  a 
  black 
  line 
  below, 
  while 
  the 
  sulci 
  on 
  the 
  disc 
  are 
  

   unicolorous. 
  

  

  Both 
  macropterous 
  and 
  brachypterous 
  forms 
  are 
  known 
  ; 
  the 
  former 
  seems 
  to 
  

   be 
  more 
  common 
  than 
  the 
  latter, 
  which 
  is 
  known 
  in 
  the 
  female 
  sex 
  only 
  and 
  has 
  

   been 
  named 
  by 
  Krauss 
  var. 
  abbreviata.

  This 
  species 
  is 
  very 
  intimately 
  related 
  to 
  H. 
  daganensis, 
  the 
  only 
  significant 
  

   difference 
  between 
  them 
  being 
  in 
  the 
  shape 
  of 
  the 
  male 
  subgenital 
  plate, 
  and 
  this 
  

   may 
  prove 
  to 
  be 
  not 
  quite 
  constant 
  when 
  longer 
  series 
  are 
  studied. 
  There 
  seems 
  to 
  

   be, 
  however, 
  a 
  more 
  or 
  less 
  constant 
  difference 
  in 
  the 
  dimensions, 
  H. 
  oryzivorus 
  

   being 
  smaller 
  on 
  the 
  average, 
  and 
  I 
  think 
  it 
  may 
  justify, 
  when 
  the 
  distribution 
  of 
  

   both 
  species 
  is 
  taken 
  into 
  consideration, 
  at 
  least 
  their 
  subspecific 
  separation 
  ; 
  in 
  the 
  

   meantime, 
  and 
  especially 
  for 
  the 
  practical 
  purposes 
  of 
  economic 
  entomologists, 
  it 
  

   may 
  be 
  more 
  convenient 
  to 
  treat 
  them 
  as 
  separate 
  species. 
  

  

  Carl 
  described 
  the 
  species 
  from 
  two 
  females 
  only 
  and 
  he 
  felt 
  inclined 
  to 
  attribute 
  

   to 
  it 
  the 
  male 
  figured 
  by 
  Lefroy 
  (Mem.
