Dryocosmus imbricariae

Andricus imbricariae
Holcaspis fasciata
Dryocosmus fasciatus

William Beutenmueller calls the attention of the writer to the fact that fasciata Bassett, described from Q. ilicifolia, is the same as imbrecariae Ashmead described from Q. ilicifolia and imbricaria. A comparison of the types confirms this conclusion. The original spelling imbrecariae is a typographical error and Ashmead had corrected it in his own copy of the paper to conform it with the name of the host oak. This "banded bullet" gall was reported by Miss Stebbins from two other host oaks, Q. coccinea and velutina. The writer here records as additional hosts, Q. rubra, marilandica, cinerea, catesbaei, texana, and lawifolia and the following localities where the galls have been seen : Ithaca, N. Y. ; Evanston, Wilmette, Winnetka, Glen Ellyn, and Kingston, IL. ; Kilbourn City and Dele- van (D. Watt), Wis.; Webster Groves, Ironton, and Poplar Bluff, Mo.; Little Rock, Hot Springs, and Texarkana, Ark.; Hugo, Okla. ; Palestine, AVharton, Victoria, and Boerne, Tex.; Troy and Dothan, Ala.; Cottondale, Marianna, River Junction, Madison, Live Oak, Gainesville, and Ocala, Fla. ; Bluemont, Va. ; Kanawha Station (A. D. Hopkins), W. Va., and Washington, D. C. Brodie collected galls on Q. coccinea at Toronto.

Galls collected at Evanston in fall of 1916 gave adults September 22, 1917, but a few galls still contained larvae indicating that the emergence is distributed over at least two seasons. From galls collected in fall of 1917 at Ironton flies issued before October 10, 1918, and some still contained larvae. Galls from Poplar Bluff in fall of 1917 gave flies October 10, 1918. From galls collected at Victoria, Tex., J. D. Mitchell reared flies November 20, 1906. The Ashmead types emerged September 6 and October 12 and Bassett's type flies also emerged in the fall.
