Eumayria floridana Ashmead.

Eumayria multiarticulata (gall only)

Gall. On the roots of laurel-leaf oak (Quercus laurifolia). Polythalamous. Hard, rounded and composed of many hard larval cells. 

Habitat: Florida.

Solenozopheria vaccinii Ashmead.

Gall. (Plate LI, Figs. 2-8.) On the stems of various kinds of blueberry (Vaccinium pennsylvanicum, V. corymbosum, V. canadense, V. vacillans), and huckleberry (Gaylussacia dumosa, G. frondorsa, G. resinosa). Polythalamous. Green and fleshy when fresh, brown, hard and pithy when old and dry. Irregularly rounded, and usually kidney shaped. Concave at the place of attachment to the stem, turning the same downward. Diameter 12 to 25 mm. 

Habitat. Canada to Florida and Texas. 

The gall is usually very abundant, but the true gall-maker seems to be difficult to obtain. I have had hundreds of the galls, but have not as yet succeeded in rearing the gall-fly. The galls are mostly always infested by a species of guest-fly, which cause the larvae of the gall-maker to succumb before reaching maturity. The gall-fly is known only by a single female, in the United States National Museum.
