New American Cynipid Wasps From Galls

Trichoteras rotundula, new species

Host. — Quercus chrysolepis.

Gall (pl. 16, fig. 2). — A midrib cluster of a few globular galls, usually on the under side of a leaf in the fall. Covered with short straight hairs when young and green, later bare, smooth, tan, up to 2.7 mm. in diameter with a central cell 1.5 by 1.2 mm. supported by stout radiating fibers.

Habitat. — The type emerged in November from a gall collected at Camp Baldy, Calif., on November 7, 1939. One paratype was cut out September 5, 1918, from a gall collected at Los Gatos. Another was cut out November 10, 1949, from a gall collected at Idyllwild on November 6, 1948. One (not in the type series and all amber) was cut out dead in 1946 from a gall collected on Mount St. Helena in August 1922.
