My first practical acquaintance with this species began at New Brunswick, N.J., in the spring of 1889. In the Rutgers College campus there are a considerable number of elms, many of them grand old trees, which for several seasons ins succession and up to 1888 had been defolidated by Galeruca xanthomelœna, larva and imago. A double row of young trees, many of them elms, extends from the College campus to the Theological Seminary, a distance of about 280 yards, and at the beginning of this row, most distant from the Seminary, the Experiment Station building in situated. There are also a considerable number of elms among the other shade trees in this part of the city.
