2(l4 LITIIOCOLLKTID.K. 



Very common among oaks in June. The larva (according to 

 Eatzebnrg) mines in the autninn in oak-leaves, making large 

 white blotches, within which the larva may be observed in a 

 curved position ; the mined leaves remain perfectly flat. The 

 larva, when full-fed, spins its cocoon within the leaf, but remains 

 unchanged till spring; there does not appear to be more than 

 one brood in the year. (I have repeatedly met with the larvoe, 

 but have not hitherto succeeded in rearing them.)

 rowly /«.sfo//.s at the base, more broadly towards the apex, the hinder 

 margin broadly fmcona, with a round black spot above the anal angle ; 

 cilia at the apex ochreous, at the anal angle grey. Posterior wings fus- 

 cous, with paler cilia. 



Common among brambles in May and August. The larva 

 mines the leaves of the bramble in autumn and winter, and in 

 July; the mines appear as whitish blotches, palest at their origin, 

 of a cornucopia shape; they pucker the leaf a little; the larva 

 changes to a pupa in the mine, not forming a cocoon; the jjujki 

 is extremely active.
