Andricus bracteatus, new species.

A terminal bud gall, globular, up to 8.4 mm. in diameter, more or less covered with leafy bracts, which are green when young, becoming tan. Occurs in fall. Monothalamous, with a thick cavernous wall.

The type is selected from a series from galls collected by Mrs. N.W. Capron on November 1, 1935, at Young, Ariz., on an undetermined oak, the adults emerging some time before April 1936. Two paratypes are from galls on Quercus oblongifolia, which see sent from Nogales on February 4, 1935, then containing live adults. Two others are from Wolf Creek Camp, 10 miles from Prescott, Ariz. One is from a gall the writer collected in the Santa Rita Mountains, Ariz., on December 7, 1921, on Q. diversicolor containing a living adult and one from a gall from the Huachuca Mountains on the same host. These galls were seen on Q. arizonica also at Oracle and on Q. toumeyi at Patagonia, Ariz.
