Feron scutellum (agamic)

Atrusca capronae (agamic)

Trigonaspis mediocre (agamic)

Andricus scutella, new species

Hosts: Quercus subturbinella [turbinella]

Gall. — A cup-shaped spangle up to 4.5 mm. in diameter and 3.5 mm. high, brown with a whitish bloom, attached to underside of leaf. The edge of the cup is thin, not in-rolled, often collapsed. The larval cell 2 mm. long by .7 mm. in diameter is placed transversely in very base of cup. The exit hole is into the bottom of cup. The gall resembles that of Trigonaspis cupella Weld on the same host, but lacks the in-rolled margin and dark color of that species and the adult is fully winged.

Range: AZ

Diplolepis capronae, new species

Host. — Quercus subturbinella Trelease.

Gall. — Globular, 8 to 18 mm. in diameter, attached to midrib or strong vein on under side of leaf. Its straw-yellow color with vertical purple streaks makes it a beautiful object when fresh. The outer shell is about half a millimeter thick and crinkly radiating fibers support a central larval cell.

Xanthoteras mediocre, new species

Host.--Quercus subturbinella Trelease

Gall.-- Similar in color and structure to the gall of [Xanthoteras forticorne](https://www.gallformers.org/gall/851) (Walsh) but not so large. The clusters are roughly globular, about 20 mm. in diameter, on young shoots under debris. The individual fig-shaped galls contain from 2-6 cells, while those of forticorne are monothalamous. 

Habitat. — The type material is from Camp Creek, Arizona. Mrs. Capron sent galls on November 20, 1928, and living flies were cut out on December 8. On December 27, 1928, she collected another lot of galls and flies were cut out January 2 and others emerged indoors about January 22, 1929.
