Xanthoteras mediocre, new species

Host.--Quercus subturbinella Trelease

Gall.-- Similar in color and structure to the gall of Xanthoteras forticorne (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.
