Fig. 'X Fig. 4. iBTeiied. Digitized by Google Digitized by Google 6 So far as known to me, this is the first instance of this insect having been observed attacking nursery trees, and also the first record of their working below the ground. All previous rec- ords represent them as working above the surface, their attacks being confined to the trunk and larger branches. Dr. Harris states that the adult Saperda vestita (Fig. 3), after having emerged from the trunk and larger branches of the trees,... will fly into the top and there feed upon the epidermis of the tender twigs and the petioles of the leaves, often wholly denuding the latter and causing the leaves to fall. It may not be out of place to state that a few years ago a specimen Saperda Candida (Fig. 5) was sent me, accused of gnawing into the young growing apples, and specimens of these that accom- panied the insect gave abundant evidence of the truth of the statement. The species under consideration is said to deposit their eggs, two or three in a place, upon the trunk and branches, especially about the forks, making slight incisions and punc- tures for their reception with their strong jaws.
