Callirhytis rugulosa (agamic)

Amphibolips quercuspomiformis (agamic)

Andricus rugulosus, sp. nov.

Gall. — Singly or in clusters of two to about eight, on the trunks of young trees or along the stems of very young shoots of red and black oaks (Quercus rubra and Quercus velutina) late in April until early in May (8th), when the leaves begin to develop. Monothalamous. Ovate or bud-like, somewhat rough and longitudinally ribbed. Bluntly pointed at the apex. Soft, fleshy and green when fresh, often tinged with red. Hollow inside. When mature they drop to the ground, and when old they turn brown and become thin-shelled, with a large chamber inside. Length, 5-6 mm.; width, 3-3.25 mm. 

Habitat. — New Jersey (Fort Lee district) ; New York (Van Courtlandt Park). 

The perfect insect reaches maturity late in October, but does not emerge from the gall until April in the year following. The species is closely allied to [Andricus (Trisolenia) saltatus Ashm.](https://www.gallformers.org/gall/878) and punctatus Ashm. The gall exudes a honey-like liquid, which is greedily partaken by ants, and, like A. saltatus has the power of jumping, due to the contraction and sudden relaxation of the larva within.

Andricus yosemite, sp. nov.

Gall. — On the twig of Quercus chrysolepidis, in August. Polythalamous. Irregularly rounded or almost globular, with a small nipple at the apex. It is covered with many short spine-like projections. The surface is also somewhat wrinkled. Light yellowish brown, with some of the spines tipped with pink. Inside it is completely filled with a light brown porous or pulpy substance, and at the base at the place of attachment to the twig are a number of hard oval larval chambers close together, and imbedded in the soft part of the gall. Diameter about 20 mm. Larval chamber 4 mm. long. Habitat. — Foot of Yosemite Falls, alt. 4,000 feet, Sierra Nevada, California. (Alfred C. Burrill.) 

Described from five females cut from the gall. The species is allied to A. singularis and A osten-sackenii in sculpture of the head, thorax and scutellum.
