Head and face orange-luteous. Palpi pale. Antenne dark fuscous, 
basal joint whitish. Anterior wings black, with a whitish patch at the

rather triangular whitish-yellow spot, and Jeyond it on the inner margin 
is a larger triangular whitish-yellow spot; cilia whitish. Posterior 
wings pale grey, with paler cilia. 
Abundant among oaks in June. The pale greenish-white larva 
mines the leaves of the oaks in autumn; it keeps Close to a rib 
of the leaf, and though its mine is narrow, it turns upon itself so 
as to form a small blotch. It is a singular fact in vegetable phy- 
siology, that when the leaves are turning brown, the spots tenanted 
by these larvae remain green much longer than the remainder of 
the leaf, and this may frequently be observed in the leaves after 
they have fallen.
