ART. 10 GALL-INHABITING CYNIPID WASPS WELD 27 



tyi^es are labeled Jacksonville. The writer collected galls at Jack- 

 sonville on April 4 from which not all the adults had yet emerged. 

 Galls were noted on Q. phellos at Richmond, Falls Church, Clarendon, 

 and Alexandria, Va., and at Chesapeake Beach, Md. In Virginia 

 the galls appear with the opening of the buds in spring and are 

 about full grown by the middle of April when the leaves have 

 reached about half their normal size. For rearing they should not 

 be gathered until they contain pupae or adults. Falls Church galls 

 gave adults May 8-15, 1920. Clarendon galls gave flies May 14—18, 

 1!)21. It is questionable whether this name should be maintained 

 as distinct from palustris (Osten Sacken). 



DIPLOLEPIS NOTHA (Osten Sacken) 



Galls Avere collected at Evanston, Winnetka, Glencoe, Fort Sheri- 

 dan, and Waukegan, 111. Adults issued June 7, 1909, before June 4, 

 1913. June 3, 1915. At Washington, D. C, flies issued on May 18 

 from galls on Q. palustris.

 Nuhiln was described from an unknown oak from Mule Pass 

 Mountains, Ariz., the galls collected in November. The writer has 

 collected galls in several localities in Arizona and on several hosts. 

 The species seems to be most common on Q. arizonica and galls were 

 taken at Bisbee, in Chiricahua Mountains (flies emerging January 

 2). in Ramsey Canyon in Huachuca Mountains, at Patagonia, in 

 Tumacacori Mountains (flies out of January 13, February 6 and 10), 

 in Santa Rita Mountains and at Oracle in Santa Catalina Range. 

 Galls collected at Oracle December 17, 1921, gave adults December 

 31. January 3, 4, 10, 12, 14, 16, 22, 23, 24, and February 6. The 

 forest insect collection has galls from the Santa Catalinas from 

 which adults emerged March 30, 1916. Galls on Q. toumeyi were 

 collected in the Patagonia Mountains on December 12, 1921, and 

 flies emerged January 13 and 24 and February 4. The flies from 

 arizonicci range from 2.6-4.6 mm. Average of 58 specimens 2.88 mm. 

 Those from toumeyi average smaller but all measured were within 

 the range of the arizonica series. The writer collected the galls on 

 Q. ohlongifolia in the Huachuca, Patagonia, Santa Rita, and Santa 

 Catalina Mountains and at Nogales but reared no adults. The galls 

 were noted also on Q. reticulata in the Santa Catalina Mountains. 

 Incomptus was described from two adults cut out of galls of an 

 unknown oak at San Luis Potosi, Mexico. The writer has examined 

 both, comparing one directly with a Basset type of mihila. As the
