ELACHISTA. 259 
which is less sharply defined than the inner edge being very nearly 
straight ; cilia grey, but at the apex, beyond the dark hinder marginal 
line, yellowish. Posterior wings grey, with paler cilia. 
Common in hedges in May and August. The larva feeds in 
March and April, in the upper part of the leaves of a coarse- 
growing grass (I had thought this grass was Medica uniflora, 
but am now doubtful on that point ; it is not a very easy matter 
to distinguish each species of grass from an examination of the 
leaf only); its mines are rather puckered and brownish; the sum- 
mer brood of the larva I have not observed.

Common in marshy ground in May and at the end of August ;
