The bramble-leaf miner seems also to differ fromthat of the rose-leaf, by eating the pulp both fromthe upper and under surface, at least the track isequally distinct above and below; yet this may arisefrom the different consistence of the leaf pulp, thatin the rose being firm, while that of the bramble issoft and puffy. On the leaves of the common primrose {Primulaveris), as well as on the garden variety of it, thepolyanthus, one of those mining caterpillars may veryfrequently be found.
