The gall (PI. 2, fig. 9) consists of parts of the abort ed ovary and lower corolla-tube. In the case of those containing larvae the inside of the tube becomes quite pubescent; but this disappears with the formation of the pupa. The length is 5 mm., the width 2 mm. The upper part of the corolla retains the bud-like structure until the adult pushes through it. The galls appear as buds until the fruits mature.
