  projection, 
  the 
  colour 
  being 
  darkest 
  at 
  the 
  bottom 
  of 
  the 
  furrows 
  

   thus 
  formed. 
  Fixed 
  at 
  the 
  anal 
  extremity 
  to 
  the 
  upper 
  surface 
  

   of 
  a 
  blade 
  of 
  grass 
  near 
  the 
  part 
  where 
  in 
  separates 
  from 
  the 
  stem, 
  

   and 
  held 
  secure 
  within 
  the 
  curvature 
  of 
  the 
  leaf 
  by 
  a 
  silken 
  thread 
  

   thrown 
  across 
  the 
  body 
  beyond 
  the 
  middle, 
  the 
  surface 
  of 
  the 
  leaf 
  

   at 
  this 
  spot 
  being 
  covered 
  with 
  a 
  slight 
  web 
  of 
  silk.

  Often 
  found 
  in 
  chalky 
  places 
  among 
  

   grass 
  in 
  June 
  and 
  August, 
  being 
  one 
  of 
  the 
  commonest 
  of 
  our 
  

   small 
  moths 
  in 
  such 
  localities. 
  The 
  sexes 
  differ 
  considerably 
  in 
  

   colour, 
  the 
  female 
  being 
  smaller 
  and 
  darker 
  than 
  the 
  male, 
  and 
  the 
  

   fasciae 
  whiter 
  and 
  more 
  distinct. 
  

  

  The 
  species 
  is 
  altogether 
  very 
  similar 
  to 
  E. 
  nigrclla, 
  but 
  inde- 
  

   pendent 
  of 
  differences 
  in 
  the 
  perfect 
  insects, 
  there 
  are 
  the 
  others 
  

   of 
  the 
  larva 
  and 
  its 
  habits 
  which 
  indicate 
  a 
  distinction.

  Mines 
  upwards 
  in 
  leaves 
  of 
  Melica 
  uniflora 
  (fig.

  making 
  a 
  

   brownish

  separated. 
  It 
  burrows

  sometimes 
  two 
  larvae 
  are 
  in
