on November 24 and it lived in a pill-box until January 1. Galls 

 have been observed at Nogales and in the Mule, Huachuca, Pata- 

 *ronia, and Tumacacori Mountains. 



CYNIPS STROBILANA Osten Sacken 



Galls of this species were collected on Que7xus hicolor at River 

 Grove and New Lenox, 111. ; at Ironton, Mo. ; and at Great Falls, Va. 

 They were found on Q. 7nacrocarpa at Algonquin, 111., at Fort 

 Worth, Tex., and Miss Howe collected them at Ithaca, N. Y. Wil- 

 liam Beutenmueller writes that they were very abundant in the fall 

 of 1922 at Highwood. N. J. Galls collected in Chicago area Novem- 

 ber 1, 1914, then contained a few adults as well as larvae. When 

 opened April 24, 1916, larvae and living flies were found in about 

 equal numbers. It is inferred that some flies emerge each spring 

 for at least three seasons and Packard records finding an adult and 

 a pupa in galls six years old. Galls were collected on Q. lyrata at 

 Poplar Blufi^, Mo., and at Hoxie and Texarkana, Ark., in November, 

 1917, when the fresh galls were almost solid and cut like cheese and 

 the old galls contained pupae or adults which emerged and died in 

 breeding cage before the middle of the next May. 



CYNIPS SULCATA Ashmead 



Described from '* live oak " from Fort Grant, Ariz., the writer 

 has collected galls and reared flies which agree with the Ashmead 

 types from QuercuH arizonica^ ohlonr/ifolia^ and reticulata. The 

 Ashmead type galls seem to be on Q. aHzonica. Galls on ai'izonica 

 collected December 17 at Oracle contained pupae, adults emerging 

 April 1-27. Galls from the Mule Mountains contained adults and 

 pupae on January 13, flies emerging April 25. Adults emerged 

 April 16-26 from galls collected in the Chiricahua Mountains. Galls 

 from the Tumacacori Mountains gave flies March 8, April 6 and 26. 

 In the Santa Rita Mountains on December 7 galls on Q. ohlonglfoVia 

 were greenish or if in the sun mottled with pink and just beginning 

 to harden, containing full-grown larvae. Living flies were cut out 

 on February 4. (xalls were observed at Prescott. Nogales, Bisbee, 

 and Patagonia. 



CYNIPS WASHINGTONENSIS Gillette 



The species was described from one specimen from Olympia. 

 Wash., from Q. garryana. McCracken and Egbert reported it on Q. 

 lohata. du77iosa, and durata. The writer has collected galls on all 

 these hosts and on Q. douglasii also as follows: on Q. garryana at 

 Shelton and Tillicum. Wash., at Odell, Albany, Corvallis (adults 

 nearly all emerged by August 24, 1916), Cottage Grove (some in 

 pupa state July 18), Oakland, Wolf Creek. Holland, and Siskivou.
