  Salius 
  (Mygnimia) 
  EXCELSUS, 
  Ca7n. 
  

  

  Has 
  the 
  typical 
  Heniipepsis 
  wing. 
  Head 
  slightly 
  convex 
  

   in 
  front 
  and 
  behind. 
  Eyes 
  not 
  arcuate 
  at 
  top, 
  parallel 
  or 
  

   nearly 
  so 
  ; 
  ocelli 
  in 
  a 
  curve 
  ; 
  the 
  posterior 
  separated 
  from 
  

   each 
  other 
  by 
  a 
  distinctly 
  greater 
  distance 
  than 
  they 
  are 
  

   from 
  the 
  eyes 
  ; 
  the 
  ocellar 
  region 
  raised, 
  a 
  depression 
  on 
  

   either 
  side 
  of 
  it. 
  Clypeus 
  convex, 
  the 
  apex 
  depressed, 
  

   waved 
  inwardly 
  in 
  the 
  centre. 
  Pronotum 
  a 
  little 
  shorter 
  

   than 
  the 
  head, 
  the 
  sides 
  rounded, 
  narrowed 
  towards 
  the 
  

   base 
  ; 
  the 
  apex 
  roundly 
  concave. 
  Pronotum 
  short, 
  sharpl}' 
  

   oblique 
  from 
  base 
  to 
  apex, 
  there 
  being 
  no 
  break 
  in 
  the 
  

   surface 
  from 
  the 
  base 
  to 
  the 
  apex 
  ; 
  the 
  lateral 
  tubercles 
  

   distinct. 
  Abdomen 
  subsessile 
  ; 
  the 
  apex 
  with 
  a 
  thick 
  tuft 
  

   of 
  hair. 
  The 
  third 
  cubital 
  cellule 
  at 
  the 
  top 
  is 
  a 
  little 
  

   longer, 
  at 
  bottom 
  considerably 
  shorter 
  than 
  the 
  second 
  ; 
  

   the 
  second 
  recurrent 
  nervure 
  received 
  a 
  little 
  before 
  the 
  

   middle 
  — 
  a 
  little 
  less 
  than 
  the 
  length 
  of 
  the 
  second 
  transverse 
  

   cubital 
  nervure 
  ; 
  the 
  anal 
  nervure 
  in 
  hind 
  wings 
  interstitial. 
  

   The 
  long 
  spur 
  of 
  the 
  hind 
  tibiae 
  reaches 
  beyond 
  the 
  middle 
  

   of 
  the 
  metatarsus. 
  

  

  There 
  is 
  another 
  larger 
  species 
  (22 
  mm.) 
  which 
  resembles 
  

   excehus 
  in 
  colouration, 
  except 
  that 
  the 
  body 
  has 
  a 
  bluish 
  

   tinge, 
  and 
  the 
  wings 
  have 
  a 
  deep 
  purple 
  iridescence. 
  This 
  

   is 
  probably 
  vitripennis, 
  Sm., 
  from 
  Sumatra. 
  From 
  excelsus 
  

   it 
  is 
  easily 
  known 
  by 
  the 
  median 
  segment 
  having 
  an 
  oblique 
  

   slope 
  to 
  the 
  apex, 
  when 
  it 
  curves 
  down 
  obliquely 
  ; 
  the 
  

   anal 
  nervure 
  in 
  hind 
  wing 
  is 
  received 
  beyond 
  the 
  cubital 
  — 
  

   the 
  ocelli 
  are 
  larc^er.
