apex. Abdomen slightly longer than head plus thorax, length to

Types.—vU.8.N.M. No. 56377: Type and four paratypes. Paratypes 
in California Academy of Sciences and Chicago and American Muse- 
ums of Natural History. 
Gall (pl. 2, fig. 11) —A terminal bud gall, globular, up to 84 
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. , 
Host and habitat.—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 1986. Two paratypes are from galls on Quercus oblongifolia, 
which she sent from Nogales on Ferbuary 4, 1935, then containing 
living 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. 
ANDRICUS CGORTUS, new species 
Female.—Black, with more or less red on mandibles, legs, and 
ventral abdomen, especially on specimens cut out of the galls in No- 
vember. Head coriaceous; from above transverse, cheeks broadened 
behind eyes; from in front malar space 0.4 eye, striate, antennae 13-seg- 
mented, segments as (scape) 15:9:14:14:11:11:10:9:8:8:8:7: 15. 
Sides of pronotum pubescent, with faint striae. Mesoscutum covered 
with short appressed hairs, which do not hide the coriaceous sculpture,
