  Only 
  one 
  species 
  of 
  this 
  genus 
  has 
  been 
  recorded 
  from 
  

   Continental 
  India 
  — 
  E. 
  antennalis 
  West., 
  from 
  Bombay. 
  It, 
  

   and 
  the 
  two 
  species 
  here 
  described, 
  may 
  be 
  separated 
  by 
  

   means 
  of 
  the 
  following 
  table

  ;

  In 
  coloration 
  comes 
  near 
  to 
  the 
  Ceylonese 
  E. 
  erythro- 
  

   soma, 
  but 
  that 
  differs 
  from 
  it 
  in 
  many 
  respects, 
  e.g., 
  in 
  

   having 
  the 
  face 
  longitudinally 
  striated 
  and 
  keeled 
  down 
  

   the 
  middle,
