dria, Virginia, June, 1923, Quercus palustris,''^ and from it the above 

 notes were made. 



William Beiitenmiieller has suirgested in correspondence that this 

 peltatus would prove to be the same as his fondeiif^is and the rear- 

 ing of adults of peltatus now enables me to compare them with co- 

 types of foiide7\sis and they seem to me to be the same, oven Avlien 

 compared in balsam mounts. Peltatva tiius becomes a synonym of 

 the older name -fioridensis and from the characters given it will be 

 seen that the species goes in the genus Dryocosinus where it is evi- 

 dently the vernal sexual form in an alternation. 



Host. — D. fioridensis was described from Spanish oak, Q. rubra 

 {=zdigitato.=^falcata) and from Blue-jack oak, (2. chierea {^hrein- 

 folia) from Florida; peltatus from Q. marilandica., and the writer 

 here adds the following unrecorded hosts: Q. nigra., Q. imhricaria^ 

 Q. phellos., and Q. palustris. He has reared adults from palustris^ 

 rubra., and imbricaria. 



Biology. — About Washington the galls may be found just starting 

 in early May. They are then bright scarlet. As they develo]) the 

 bracts become green and unless gall is parasitized turn brown about 

 the time the adults emerge which is about the middle of June. For 

 rearing the galls must be left on the tree until the pupa stage is 

 reached and the living flies cut out of the dry galls later. May 27 

 was the earliest date at which a pupa was noted. By June 19, 1921, 

 almost all the flies were out. 



Hahitat. — The species seems to belong to the Atlantic coast plain. 

 The writer has seen galls at Chesapeake Beach, Md. ; East Falls 

 Church, Rosslyn, and Fredericksburg, Va. ; Fairfax, S. C. ; Marianna, 

 I\iver Junction, and (lainesville. Fla.; Troy and Dothan, Ala.: Pales- 

 tine, Houston, Trinity, and Texarkana, Tex.; and at Tuskahoma, 

 Okla. J. L. Zabriskie collected galls at Flatbush. N. Y.

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 conhrms 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. ruhra^ marilandica^
