It appears during the early part of July, when the female punc- tures the stem of the vine and deposits an Qgg therein, which shortly hatches, producing a tiny whitish grub, which lives within the swollen part and feeds upon it. At first the gall is small and inconspicuous, but towards the end of the season it assumes the form of an elongated knot or swelling, as shown in the figure; this is generally situated immediately above or below a joint. Usually there is a longitudinal depres- sion on one side, dividing that portion into two prominences, which commonly have a rosy tint. Within the gall the larva remains until June of the following year. When full grown, it is about a quarter of an inch long, white, cylindrical, and footless, with a large yellowish head. During the month of June it changes to a chrysalis, from which the perfect beetle is produced in about a fort- night. These galls do not appear to injure to any material extent the branches on which they occur; should they ever multiply so as to become injurious, their increase may be readily checked by cutting off and burning those portions of the canes on which they are situated, before the beetles escape.
