ART. 10 GALL-INHABITING CYNIPID WASPS WELD 41 



Flagstaff, Williams, Grand Canyon, and in Santa Catalina, Chi- 

 ricahiia, and Huachuca Mountains, Ariz. In all cases the collecting 

 has been done at such a time that the maker has not been reared. 

 The flies probably emerge just as the new wood begins to harden in 

 midsummer. 



DISHOLCASPIS SPONGIOSA (Karsch) 



The galls of this species were collected on Quercus steUata, rtiar- 

 garetta, and chaprtiani at the following localities: Thebes (E. 

 Schwab) and Floyd's Island in Okefenokee Swamp (Dr. J. C. 

 Bradley), Ga. ; Green Cove Springs, Daytona, St. Petersburg, Clear- 

 water, Ocala, Gainesville, Madison, Marianna, River Junction, and 

 Tallahassee, Fla.; Montgomery and Troy, Ala.; Mineola, Palestine, 

 Trinity, and Houston, Tex. ; Texarkana, Hoxie, and Hot Springs, 

 Ark.; Hugo and Tuskahoma, Okla. ; Poplar Bluff and Ironton, Mo. 

 In 1917 adults had emerged at Poplar Bluff by November 3, at 

 Hoxie they contained pupae on October 10 and emerged November 

 16, at Palestine they contained pupae and adults on October 16. 

 They emerged from Daytona galls on December 5.

The writer has collected the common fusiform stem swelling of 

 this species on Quercus emoryi at Fierro, Kingston, and in the 

 Burro Mountains, N. Mex.; in the Chiricahua, Huachuca, Mule, 

 Patagonia, Tumacacori, Santa Rita and Santa Catalina Mountains, 

 and at Bisbee, Nogales, Oracle, and Prescott, Ariz. The galls were 

 seen on Quercus hypoleuca in the Santa Catalina, Patagonia, 

 Huachuca, and Mule Mountains and at Fierro and Kingston. In 

 April, June and July only old galls were found. E. Jacot collected 

 a fresh gall in the Huachucas September 17, too immature to rear. 

 The writer collected mature fresh galls on emoryi at Oracle on 

 December 17 containing both pupae and adults which emerged 

 January 4-24. Galls on emoryi from the Mule Mountains collected 

 early in December gave adults December 31, January 13, 24, Febru- 

 ary 4 and 14. These flies run to Dryocosmus in the Tierreich key.

These galls long known in literature under the name decidua 

 before the adult was reared are the ones to which Dr. A. D. Hop-
