 season. Unusually early and late records are: March 23 at Carmel, 

 Calif.; April 14 at Black Point, Marin Co., Calif.; May 1 at Robson,

Rearing records are as follows: 1 rearing from Andricus gplls, 2 in 

 Oregon from "Cynips maculipennis," 1 from galls of Disholcaspis 

 eldoradensis, 9 from galls on Quercus, 15 from "oak apple" (a cynipid

 of Quercus lobata, 1 from Quercus, 2 from nuts of wild Corylus, 3 from

This species is widely distributed in western United States and in

 The hosts are varieties of larvae in many kinds of galls and nuts, 

 particularly on Fagaceae.
