Ai:x. 10 GALL-INHABITING CYNIPID WASPS WELD 107 



near Bisbee in Mule Mountains, and in the Santa Catalina Moun- 

 tains. The National Museum has galls from the Santa Rita and 

 Chiricahua IMountains and from Fort Grant. The writer has not 

 reared adults. Seventeen of the types range from 5.2-6.3 mm. 

 Average 5.G mm. 



AMPHIBOLIPS NUBILIPENNIS (Harris) 



This species forms a fleshy translucent yellowish-white gall 

 resembling a green grape attached to the under side of leaf in 

 spring. A gall on Quercus cocci nea at Miller, Ind., contained a 

 pupa on May 30 and another found June 30 showed an exit hole 

 where the maker had recently escaped. Galls were seen on red oak, 

 Q. maxima^ at Fort Sheridan, 111., and at Indian Falls, N. Y. Crosby 

 collected a lot of fresh galls 10-22 mm. m diameter at Farmingdale, 

 N. Y., on June 14, 1914, on Q. coccinea and velutina and from these 

 a male issued June 22, another June 23, and two females June 24, 

 and one June 25. Four-fifths of the galls were parasitized. 



AMPHIBOLIPS RACEMARIA (Ashmead) 



This species was described from females from " Florida " on 

 Q. laurifolia. The types are labeled " Jacksonville " and with them 

 is a male of a subsequent rearing determined by Ashmead. The 

 writer collected galls on Q. laurifolia at Daytona, Clearwater, and 

 Ocala; also on Q. phellos at Jacksonville, Carrabelle, and Gaines- 

 ville, rearing one adult, a female, some time after April 23. The 

 flies are closely related to nubilipennis (Harris) and a comparison 

 of a larger series of specimens may show that it is not worth wliile 

 to maintain the name raceinaria for individuals attacking southern 

 oaks. There is a similar gall on Q. nigixi at Texarkana, Ark., and 

 on Q. iiiibricaria about Washington but no adults have been reared. 



AMPHIBOLIPS SPINOSA Ashmead 



This species w\as described from one specimen from " Florida " 

 reared in January, the gall on Q. laurifolia. The writer has found 

 the gall on Q. phellos also and at the following localities : Jackson- 

 > ille, Daytona, Live Oak, Madison, River Junction, Tallahassee, 

 Gainesville, and Clearwater. Among galls collected on ground at 

 Madison on October 21, 1919 some contained pupae but the adults 

 never emerged. When the galls were cut open October 10, 1920 

 moulded adults, a pupa and a larva were found. These adults were 

 females. 



AMPHIBOLIPS TINCTORIAE Ashmead 



Galls on Q. velutina have been collected in the fall at Poplar Bluff, 

 Mo, ; Moline, 111. ; and Washington, D. C. The type flies emerged 

 October 16, locality unlmown. The Avriter has never reared adults.
