2 of each sex (Weld No. 131) from the galls of Acmspis maerocarpae 

 Bassett at Evanston, 111. ; 3 females and 1 male from the woody form 

 gall of Neuroterus noxiosus (Bassett) on swamp white oak {Q. hi- 

 color) at Evanston, 111.; 4 females and 2 males from the gall of 

 Acj'ospis viacrocarpae Bassett at the same place ; 1 female and 2 males 

 from the gall of Andncm murtfeJdtae Ashmead on Q. stelluta, East 

 Falls Church, Va. ; and the same collector deposited in the United 

 States National Museum 3 females and 2 males (Hopkins U. S. 

 15634'"), all only 2 mm. long and with apex of scutel and the pro- 

 podeum in part black, from the galls of G ompsodryoxenus humilis 

 Weld on Q. chapmanl, June 30, 1920, at Ocala, Fla. 



In the United States National Museum are also 6 females and 

 4 males that can not be separated from fiava Ashmead except by size. 

 But all grades of size occur in the material of different lots before 

 me. The present 10 specimens were reared by Theodore Pergande 

 on June 16-21, 1883, from galls of Neuroterus hatatus (Fitch) on 

 Q. alba^ in Virginia. R. A. Cushman reared a female and two males 

 (Quaintance No. 7173) from an oak gall at Vienna, Va., August 16, 

 1911. The males are of special interest because they have more 

 black above on the thorax than the average individual of this sex. 

 A series of 11 females and 9 males (No. 2251) are small but other- 

 wise not distinguishable from flava. The galls from which these 

 came were not identified, but the following description of them 

 remains in the records of the Museum : " These galls are sometimes 

 on the leaf stem and connected with the main twig, sometimes on the 

 leaf but always entirely deforming the leaf. They have a com- 

 pound appearance like a coalescence of several buds, shape irregular 

 but usually globular." They were received at Washington, D. C, 

 on June 20, 1880. 



Dr. A. C. Kinsey sent 4 females and 7 males from galls of Neuro- 

 ter'us hatatus noxiosus form noxiosus (Bassett) on stems of Q. hicolor 

 at Waterbury, Conn. These specimens were a part of the collection 

 of Homer F. Bassett. Another series, 19 females and 3 males, were 

 received from Doctor Kinsey, who reared them from the galls of 

 Andricus aclculatus Beutenmueller on Q. stellata at Yoakum, Tex., the 

 gall makers having been reared November 30, 1919. I also have 12 

 females and 5 males reared by Kinsey at Forest Hills, Boston, Mass., 

 in 1919 from the galls of Cynips (Acraspis) pezoiiiachoides Osten 

 Sacken, which makes its galls on Q. alba. The specimens from the 

 latter galls are as a whole distinct from all other -flowa at hand, but 

 the differences are only in the color, which is generally darker. Their 

 form, proportions of the antennal joints, sculpturing, vestiture, and 

 wing bands are in all respects like the typical -flava. One male, reared 

 by Dr. L. L. Huber at Bluffton, Ohio, on April 12, 1921, from the
