Dryocosmus rileyi
Andricus rileyi
This species was described from St. Louis, Mo., from Q. maxima [rubra] only. The writer has collected the galls on ten other oaks as follows : Q. velutina, coccinea, marilandica, rubra, cinerea, nigra, catesbaei, imbricaria, texana, and laurifolia, and records the following localities: Evanston, Winnetka, and Ravinia, IL.; Ironton and Poplar Bluff, Mo. ; Little Rock, Hot Springs, and Texarkana, Ark. ; Palestine, Trinity, Wharton, Richmond, Boerne, and Kerrville, Tex.; Hugo and Tuskahoma, Okla. ; Troy, Ala.; Cottondale, Marianna, and Ocala, Fla. ; Washington, D. C. ; Bluemont, Va. ; Kanawha Station, W. Va. (A. D. Hopkins) ; Riverhead, N. Y. (C. R. Crosby); New York City (Beutenmueller).
Galls collected at Poplar Bluff in fall of 1915 gave adults Septemer 25-October 21, 1916. From galls collected at Ironton in fall of 1918 by S. A. Rohwer two flies emerged March 15, 1920. From galls of 1911 on coccinea at Evanston adults emerged June 15, 24, 1912, and others in spring of 1913. As the mesoscutum of the type is smooth, the head sculptured, claws simple, no malar groove and third segment of antenna longer than fourth the species is here transferred to Dryocosmus.
