 F2, latter about as long as each of F3 to F5, these broadening slightly 

 toward club and scarcely longer than broad, club slightly longer than 

 F4 and F5 combined ; dorsum of thorax umbilicately punctate, meso-

Type locality. — San Bernardino, Calif. 



Ty/je.— Female, U.S.N.M. No. 42236. 



ReTnarks. — The type, the allotype, and 18 female and male para- 

 types were reared by Dr. A. C. Kinsey from the leaf galls of Andri- 

 Gus lasius areolarius Kinsey taken at the type locality on Quercus 

 chrysolepis. The gall maker came from the galls on January 31, 

 1920. The allotype and a paratype of each sex are with the type in 

 the United States National Museum. The rest of the paratypes are 

 in the writer's collection. 



It was reared as follows by Doctor Kinsey in California from 

 cynipid galls: Andricus lasius sublasius Kinsey on Q. cht^jsolepis^ 

 Pasadena and San Jacinto; A. lasius lasius Ashmead on Q. chryso- 

 lepis^ El Portal; same gall and oak at Dunsmuir and Placerville; 

 Plagiotrochus chrysolepidicola (Ashmead) on Q. dwmosa, at Paso 

 Robles; Disholcaspis corallina (Bassett) on Q. douglasi at Napa; D. 

 canescens (Bassett) on Q. douglasi, at Gait; and Gynips weldi var. on 

 Q. grisea, Prescott, Ariz. A good series of both sexes is involved in 

 these records. The Cynipidae were reared from these lots between 

 January 25 and April 3, 1920.
