  scales 
  in 
  front 
  which 
  are 
  brilliant 
  blue 
  or 
  dull 
  grey 
  

   according

   and

  Thorax 
  : 
  pro- 
  

   thoracic 
  lobes 
  and 
  the 
  area 
  of 
  the 
  mesonotum 
  just 
  behind 
  them 
  clothed 
  with 
  flat 
  black 
  

   scales. 
  Integument 
  of 
  mesonotum 
  shining 
  blackish 
  brown, 
  except 
  round 
  the 
  front 
  

   margin, 
  where 
  it 
  is 
  orange, 
  rather 
  sparsely 
  clothed 
  with 
  very 
  narrow 
  straight 
  sub-

  scutellum 
  with 
  flat 
  black 
  scales. 
  Pleurae 
  orange, 
  with

  Abdomen 
  

   black-scaled 
  dorsally, 
  segments

  towards 
  

   the 
  apices 
  of 
  the 
  segments 
  ; 
  venter 
  golden. 
  Male 
  genitalia 
  very 
  similar 
  to 
  those 
  of 
  

   R. 
  coeruleocephala 
  (Leic), 
  but 
  the 
  " 
  setaceous 
  lobes 
  " 
  are 
  larger. 
  Legs 
  : 
  coxae 
  and 
  

   trochanters 
  orange 
  ; 
  femora 
  black, 
  hardly 
  paler 
  beneath, 
  each 
  with 
  two 
  silvery-white 
  

   spots 
  on 
  the 
  apical 
  half 
  in 
  front 
  ; 
  the 
  middle 
  femora 
  also 
  have 
  a 
  silvery 
  white 
  line 
  

   at 
  the 
  base 
  in 
  front

  tarsi 
  black. 
  In 
  the 
  male 
  the 
  claws 
  of 
  the 
  front 
  legs 
  

   are 
  very 
  unequal, 
  the 
  larger 
  one 
  with 
  a 
  distinct 
  tooth 
  ; 
  those 
  of 
  the 
  middle 
  legs 
  rather 
  

   small, 
  and 
  nearly 
  equal, 
  those 
  of 
  the 
  hind 
  legs 
  simple 
  and 
  equal. 
  Wings 
  with 
  small 
  

   brown 
  scales, 
  the 
  lateral 
  ones 
  narrow. 
  Base 
  of 
  the 
  upper 
  fork-cell 
  a 
  little 
  nearer

  wing

  This 
  species 
  rather 
  closely 
  resembles 
  R. 
  coeruleocephala 
  (Leic), 
  R. 
  nitidiventer 
  (Giles) 
  

   and 
  R. 
  powelli 
  (Ludlow), 
  differing 
  from 
  the 
  first 
  in 
  the 
  dark 
  colour 
  of 
  the 
  integument 
  

   of 
  the 
  mesonotum 
  and 
  in 
  the 
  greenish 
  scales 
  with 
  which 
  the 
  mesonotum 
  is 
  clothed, 
  

   as 
  well 
  as 
  in 
  the 
  claws 
  and 
  the 
  male 
  genitalia 
  ; 
  from 
  the 
  second, 
  in 
  the 
  blackish, 
  

   instead 
  of 
  blue, 
  scales 
  on 
  the 
  prothoracic 
  lobes 
  ; 
  and 
  from 
  the 
  third 
  in 
  the 
  greenish 
  

   instead 
  of 
  dark 
  brown 
  scales 
  of 
  the 
  mesonotum. 
  R. 
  nitidiventer, 
  R. 
  powelli 
  and 
  R. 
  

   vicina 
  might 
  well 
  be 
  regarded 
  as 
  forms 
  of 
  one 
  species, 
  but 
  as 
  I 
  could 
  see 
  no 
  variation 
  

   in 
  the 
  Borneo 
  specimens 
  and 
  as 
  the 
  males 
  of 
  R. 
  nitidiventer 
  and 
  R. 
  powelli 
  are 
  not 
  

   known, 
  I 
  have 
  provisionally 
  accorded 
  R. 
  vicina 
  specific 
  rank.
