Island, Md. ; and Washington, D. C. Flies emerged from the Ithaca 

 galls on June 15, New Lenox, June IG. Similar galls on Q. stellata, 

 giving similar flies, have been seen in Virginia and Texas. William 

 Beutenmueller collected them at New York City, the flies emerging 

 June 5, 1915. 



ANDRICUS WILTZAE FuUaway 



This species Avas described from Palo Alto, Calif., from Q. lobata. 

 The writer has collected galls on this oak at Palo Alto, Paraiso 

 Springs, Paso Robles, Kaweah, Visalia, Stockton, Oroville, Chico, 

 Red Bluff, Upper Lake, Lakeport, Ukiah, and Santa Rosa. Dr. 

 J. C. Bradley collected galls at Sacramento and Davis, March 9, 

 1918, and reared adults, some of which were still alive in the box 

 on May 10. The young galls may be found developing in early 

 September. The writer reared flies which agree with the Stanford 

 type from galls on Q. dumosa^ flies emerging April 5 from galls 

 collected at Descanso on March 6 and from galls collected in the 

 Santa Ana range on March IG. On March 18 a living fly was cut 

 from a gall collected in Waterman Canyon in the San Bernardino 

 Mountains. The galls were seen also at Boulevard, Ojai, and Palo 

 Alto.
