  hair. 
  Wings 
  hyaline, 
  the

   fuscous. 
  Petiole 
  covered 
  with 
  long, 
  white, 
  soft 
  hair; 
  aluta- 
  

   ceous, 
  the 
  base 
  closely 
  longitudinally 
  striated; 
  its 
  under 
  

   part 
  keeled 
  down 
  the 
  centre 
  and 
  with 
  a 
  lateral 
  keel 
  between 
  

   it 
  and 
  the 
  edge. 
  In 
  this 
  latter 
  point 
  — 
  in

  under 
  side 
  of 
  

   the 
  petiole 
  being

  the

  This 
  species 
  is 
  omitted 
  entirely 
  by 
  Col. 
  Bingham. 
  It 
  

   comes 
  into 
  his 
  section 
  " 
  C 
  : 
  median 
  segment 
  convex, 
  

   vertical, 
  with 
  a 
  well-marked 
  groove 
  down 
  the 
  middle, 
  

   widening 
  at 
  apex 
  into 
  a 
  deep 
  /\-shaped 
  hollow 
  " 
  : 
  and 
  to 
  

   sub-section 
  " 
  a 
  : 
  Petiole 
  long, 
  gradually 
  widening 
  to 
  the 
  

   apex, 
  longer, 
  never 
  shorter 
  than 
  the 
  thorax 
  and 
  median 
  

   segment 
  united" 
  ; 
  but 
  it 
  can 
  hardly 
  be 
  said 
  to 
  be 
  "medially 
  

   with 
  well 
  developed, 
  prominent 
  lateral 
  tubercles." 
  The 
  

   petiole 
  is 
  distinctly 
  longer 
  than 
  the 
  head 
  and 
  thorax 
  but 
  

   not 
  longer 
  than 
  the 
  other 
  segments 
  united 
  ; 
  its 
  basal 
  third 
  

   is 
  distinctly 
  narrowed, 
  becoming 
  gradually 
  wider 
  ; 
  the 
  

   apical 
  third 
  is 
  of 
  uniform 
  thickness. 
  

  

  It 
  has 
  pretty 
  much 
  the 
  same 
  form 
  and 
  size 
  and 
  colour 
  

   of 
  the 
  wings 
  as 
  E. 
  vishnu 
  ; 
  but 
  differs 
  altogether 
  in 
  the 
  

   colour 
  of 
  the 
  legs, 
  and 
  in 
  the 
  form 
  of 
  the 
  antennal 
  tubercle, 
  

   which 
  here 
  is 
  rounded 
  at 
  the 
  top 
  and 
  has 
  a 
  long 
  pedicle 
  ; 
  

   while 
  in 
  E. 
  vishnu 
  it 
  is 
  much 
  shorter, 
  broader 
  and 
  

   triangular 
  at 
  the 
  top 
  and 
  with 
  a 
  short, 
  broad 
  pedicle.
