Th» usual colour is a bright crimson, but it some- times inclines to green ; especially when young or on the under side of the leaf; for though it is more often found on the upper side, I have met with it antijiosed. Upon cutting into these galls, we shall find them to be hol- low, and each to contain a pale orange larva, Trhich probably resembles those already men- tioned in transforming under ground. The gall was at first briefly described by Baron .Osten Sacken (Diptera of N. A., part I., ,T). 202). Similar but distinct galls grow on the leaves of Hickory and Hackberry, but are always Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Entomological Society of Ontario; Ontario.
