ART. 10 GALL-INHABITING CYNIPID WASPS WELD 23 



Type.—Q^i. No. 27189, U.S.N.M. Type and 2 paratypes. Para- 

 types in American Museum, also in Field Museum and Stanford 

 University. 



Host. — Quercas hreviloba and Quercus laceyi. 



Gall (fig. 5). — An oak apple, 14-20 mm. in diameter, usually 

 single on under side of leaf in fall. Reddish-brown, not spotted, 

 wall thin, central cell supported by numerous silky fibers, a definite 

 Itundle of parallel fibers from cell to point of attachment of gall. 



IJahJfat.—The type material was collected in October 1917, near 

 Austin, Tex., on the shin oak, Q. hreviloha. A gall opened Novem- 

 ber 10, contained a pupa which transformed November 26. By De- 

 cember 4, adults had chewed out of the inner cell and were found 

 among the radiating fibers. The normal emergence date unknown. 

 These galls were seen also at Boerne and Kerrville. A paratype fly 

 came from a gall on Q. laceiji at Boerne, the gall containing a pupa 

 on November 20, which transformed by December 7. 



DIPLOLEPIS CENTRICOLA (Osten Sacken) 



The gall of this species is a spotted oak apple usually found singly 

 on under side of leaf of Quercus stellata in the fall. The writer has 

 r-ollected them at Ironton and Poplar Bluff, Mo.; Hoxie and Tex- 

 arkana, Ark.; and Tuskahoma, Okla. Ashmead collected galls at 

 Asheville, N. C, and J. Angus at West Farms, N. Y. Galls at Iron- 

 ton contained adults November 14 and some had already chcAved 

 their way out of the inner cell. Some emerged November 27, and 

 December 8. Galls at Hoxie contained pupae October 10, and adults 

 November 17. At Washington adults were found inside the galls 

 October 9, and 20, and on November 1, some had chewed out of the 

 inner cell.

 Jacksonville, Fla. ; saccularius from Q. coccinea and velutina in 

 Connecticut. They seem to the writer to be the same. The galls 

 have been noticed on the following oaks also: Q. rubra^ viaxima, 

 irribricaria^ marilandica., and phellos^ and at the following localities : 

 Evanston, Glencoe, Ravinia, Fort Sheridan, Waukegan, Palos Park, 

 and Moline, 111.; North East, Pa.; East Hampton (C. R. Crosby) 

 and Medina, N. Y.; Plummer Island, Md.; Washington, D. C;
