  The 
  thorax 
  varies 
  in 
  outline 
  in 
  this 
  species 
  and 
  in 
  

   E. 
  dimidiata, 
  and 
  the 
  striae 
  are 
  equally 
  fine 
  in 
  both, 
  with 
  

   a 
  tendency 
  in 
  those 
  near 
  the 
  suture 
  to 
  break 
  up 
  into 
  

   punctures 
  or 
  short 
  lineoles. 
  The 
  difference 
  in 
  the 
  colour 
  

   of 
  the 
  upper 
  surface 
  is, 
  however, 
  constant 
  throughout 
  a 
  

   fair 
  series 
  of 
  each, 
  the 
  head 
  and 
  thorax 
  being, 
  in 
  

   E. 
  dimidiata, 
  always 
  strongly 
  contrasted 
  in 
  colour 
  

   (metallic-green) 
  with 
  the 
  elytra, 
  which 
  vary 
  from 
  cop- 
  

   pery 
  red 
  to 
  golden 
  green. 
  The 
  mesosternal 
  process 
  in 
  

   E. 
  chrysopJiana 
  is 
  immarginate 
  at 
  the 
  apex, 
  in 
  E. 
  dimi- 
  

   diata 
  (which 
  Chaudoir 
  places 
  in 
  the 
  section 
  of 
  the 
  genus 
  

   having 
  a 
  margined 
  prosternum) 
  it 
  is 
  variable, 
  the 
  mar- 
  

   gin 
  being 
  often 
  feeble, 
  and 
  in 
  some 
  examples 
  quite 
  

   obsolete. 
  The 
  apical 
  ventral 
  segment 
  in 
  both 
  sexes 
  has 
  

   two 
  large 
  fovese 
  ; 
  the 
  four 
  foveae 
  of 
  the 
  ? 
  is 
  not 
  there- 
  

   fore 
  a 
  generic 
  character, 
  as 
  stated 
  by 
  Chaudoir.
