DIPLOLEPIS DUBIOSA Fullaway 



The writer has collected galls on Quercus agrifolia at Pasadena, 

 Santa Anita (contained adults April 20, emerged April 27, 1918), 

 Newhall, Piru, Fillmore, Ojai (adults emerging April 27, 1918, and 

 April 16-25, 1922), Carpinteria, Montecito, Santa Barbara, Gaviota, 

 Santa Margarita, Paso Robles, Paraiso Springs, Monterey, San 

 Juan, Palo Alto, Berkeley (galls developing in March, flies out 

 before May 8), and Santa Rosa, Calif. 



DIPLOLEPIS EBURNEA (Bassett) 



The galls of this species were described as from the leaves of an 

 unknown oak in southern Utah. The writer has collected them on 

 Quercus gambelii^ undulata^ grisea. They sometimes occur on young 

 twigs as well as on both sides of the leaves. They have been ob- 

 served at Garden of the Gods (Hopkins U. S. 10781m), Wetmore, 

 West Cliff, La Veta, Trinidad, and Morley, Colo.; Raton, Wagon 

 Mound, Shoemaker, Las Vegas, Hot Springs, Glorieta, Rito de los 

 Frijoles near Buckman, Tijeras, Magdalena, and Kingston, N. Mex. ; 

 Hackberry, Ashfork, Flagstaff, Williams, and Grand Canyon, Ariz. 

 At Wetmore the galls could have been collected by the quart on leaves 

 of young shoots of gamhelii and contained adults on October 6, 1921. 

 They emerged from early December to January 14. 



DIPLOLEPIS GEMULA (Bassett) 



Collected galls on Quercus alba at Winnetka, 111., on June 9, 1917, 

 when most of the flies had already emerged. Galls at Ravinia con- 

 tained pupae on May 23, 1919. A similar gall exists on hicolor and 

 macrocavpa in the Chicago area and in the South on prinus^ stellata^ 

 margaretta^ and 7nontanxi. 



DIPLOLEPIS IGNOTA (Bassett) 



The galls on Quercus hicolor are common about Evanston and 

 Wilmette, 111., becoming full grown by middle, of September and 

 dropping with the leaves. During the winter the woolly covering 

 weathers away more or less exposing the tan-colored galls which in 

 shape and size resemble a cluster of cocoons of the braconid genus 

 Micrcplitis. They contained pupae March 10, 1909, and adults 

 emerged April 1-15. The next spring the flios began to emerge 

 March 24. Similar galls on Q. macrocarpa were noted at Evanston 

 and Algonquin, 111., and Nebraska City, Nebr. 



DIPLOLEPIS LAURIFOLIAE (Ashmcad) 



This globular leaf gall with a free-rolling cell was described from 

 Quercus laurifolia from "Florida", the flies emerging in March. The
