Notes on cynipid wasps, with descriptions of new North American species

Amphibolips trizonata Ashmead.

The gall of this species was said to be "in the blossoms of an oak," but no description was given and the host oak unknown.

Host.--Quercus emoryi and Quercus hypoleuca

Gall.--Globular, 25-40 mm in diameter; green, turning to a tan later; smooth or with a finely coriaceous surface. Interior of a dense cellular structure lighter in color than surface, but darker toward the nonseparable larval cell in center. From the attachment a number of whitish strands run up through the cellular tissue to the larval cell. Atached singly to side of small twigs, not a flower gall.

Habitat.--AZ, NM
