On the 27th of September, 1882, while riding through Mt. Hope Cemetery, near Bangor, the leaves on several trees of Basswood (Tilia Americana) were observed to be rolled in a peculiar manner, and to contain a green larva with a black head, which I supposed at the time to be that of some Tortricid; but it quite puzzled me, as it was larger than the larva of any Tortricid in this region with which I was familiar. Miss Murtfeldt, who was riding with me at the time, said that she had seen the leaves of Basswood attacked and rolled in precisely the same manner in Minneapolis, but failed to secure any of the larve.
