lows : Q. vehdina, coccinea, marilandica^ rubra^ cinerea^ niyra^ 

 cateshaeu imhricaria, texaiw^ and laurifolia^ and records the follow- 

 infj localities: Evanston, Winnetka, and Ravinia, 111.; 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, Mari- 

 anna, and Ocala, Fla. ; Washington, D. C. ; Bluemont, Va. ; Kana- 

 wha 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 Septem- 

 erb 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 trans- 

 ferred to Dryocosnius. 



LOXAULUS MAMMULA (Bassett) 



Galls on Quercus aJha collected at Aj^ple Orchard Camp in Bed- 

 ford County, Va., on June 27, 1920, had the nutritive layer used up 

 and larvae full grown. Adults emerged some time in July. 



LOXAULUS SPICATUS Bassett 



Galls, agreeing with the Bassett type described from Arizona on 

 ""Quei^cus virens.''' have been collected by the writer from Q. ari- 

 zonica, ohlongifolia^ and tounieyi in the Santa Catalina Mountains 

 at Oracle and in Sabino Basin, in the Huacliucas at mouth of Carr 

 Canyon, in the Mule Mountains, in the Santa Ritas, and in Patagonia 

 Mountains. From galls collected in December flies emerged December 

 31, January 1 and 24. They do not seem to be congeneric with the 

 genoty^ie of this genus but the species is left in Loxcuulus for the 

 present.
