The ~'ynips quercus gernmce, is another species which deposits its future progeny in the oak buds, ad produces One of the finest galls, leafed like a rose-bud beginning to blow. Whilst the gall is small, these leaves are compressed, and are set one upon another, like the tiles of a roof. Open one of these galls, and you will find a kind of ligneous kernel, enclosing a cavity, that serves as a cradle for the little larva, which undergoes its metamorphosis in that enclosure. Oak trees afford nourishment to a multitude of insects. Barbut says, that not less than fifty species, of this tribe alone,. are supported on it.

C The Cynips roses, produces on the sweet
brier, dog-rose, &c. a gall of a singular app

small, white maggot, is discovered in the centre
of this solid, fleshy substance; and sometimes
there are several inhabitants in the same mass.
The leaves of willows are marked by large,
irregular, red swellings, during the summer,
which are caused by a small species of the
'nips, of a yellow colour, with a black thorax.
The process of foming these galls is very cu
