(locality on pin) in cynipid galls on Q. loisUzemii, February, 1886; 

 1 from Mountain View, Calif., labeled " Ehrhorn Lot 2"; 3 males 

 from galls questionably determined as Dryophanta on live oak (prob- 

 ably Q. virginiana), at Idlewild, Bexar County, Tex., L. Biediger, 

 collector; 4 males reared by Doctor Ashmead from a gall on willow 

 oak {Q. phellos), Jacksonville, Fla., April 18, 1881, and described 

 by him as a distinct species, but it has all the essential characteristics 

 of D. varians Walsh. 



L. H. Weld sent me three from the galls of Disholcaspis eldora- 

 densis (Beutenmuelier) on Q. lohata, at Cottonwood, Calif., January 

 22, and four of each sex reared by him from the galls of Biorhiza 

 caepulifomlis (Beut.) at Evanston, 111. The pins bear Weld's record 

 number 270. The rather strange shade of yellow is probably due to 

 the preservative in which these specimens were first kept, but the 

 slightly more blocky form of head hints that these specimens com- 

 prise a distinct species. Specimens at hand include 2 (No. 245) of 

 each sex from Gallirhytis gemmaria (Ashmead), Evanston, 111; 1 

 male (Hopk. U. S. 13685 «) reared February 26, 1918, from galls of 

 Disholcaspis globulus (Fitch) on Q. alba^ Falls Church, Va., by 

 William Middleton; 2 females and 1 male (Hopk. U.S. 14636^) 

 reared by William Middleton, April 27, 1920, Falls Church, Va., 

 from galls determined by him as Gallirhytis sp. on Q. alba ; 4 females 

 (Hopk. U. S. 10774'') presumably from galls on Q. stellata^ Ironton, 

 Mo., May 28, 1919, and 1 female (Hopk. U. S. 10776 ^) from same 

 locality, reared June 18, 1919, by S. A. Rohwer from galls determined 

 by him as Disholcaspis fa^ciata Bassett, on common red oak {Q. 

 'rubra) ; 3 females and 1 male (Hopk. U. S. 10781 ^) reared by J. H. 

 Pollock at Colorado Springs, Colo., presumably from galls, on an 

 undetermined species of Quercus\ 4 females and 3 males (Hopk. 

 U. S. 13651 ") reared by F. R. Herbert, February 26 and April 5, 

 1918, from galls determined by William Middleton as Disholcaspis 

 sp., from Q. durata at Los Gatos, Calif.; L. H. Weld obtained 5 

 females and 1 male (Hopk. U.S. 15608^) from the same locality. 

 May 24, 1918, presumably from galls, on Q. agrifolia^ and 1 female 

 (Hopk. U. S. 15605 '') at Upland, Calif., June 8, 1918, from Q. chrys- 

 olepis. These Hopkins lots exhibit some further noteworthy varia- 

 tions. Specimens of both sexes from California and Missouri are as 

 small as 2 or 2.1 mm. in length, and whereas the abdomen is usually 

 more or less granulose in the species, some present individuals have 

 this part perfectly smooth and polished. The setae on the sub- 

 marginal veins range from 9 to 16, both extremes being found on 

 California material. Several males from California are unusual in 

 being black, only the oral area, the front lateral portions of the pro- 

 notum, and parts of the legs brown-yellow; on the other hand, the 

 form of the head and wing band, the size and wing vestiture, and the
