ART. 2S CHALCID FLIES NOETH OF MEXICO BALDUF 49 



The type is selected from a series of nine females and four males 

 reared by the writer in the laboratory during the period of March 15 

 to April 15, 1929, from the galls of Disholcaspis glohuhis var. 

 undetermined, collected from the stems of, and from the ground 

 beneath, one specimen of Quercus michattxii at Catlin, 111., on Feb- 

 ruary 24, 1929. The galls and oak were determined by Doctor 

 Kinsey. The paratypes are in the collections of the United States 

 National Museum and the writer, and the allotype is deposited with 

 the type. 



Remarks. — The United States National Museum collection contains 

 two specimens bearing record number 66 """^ which issued on June 28, 

 1883, from the galls of D. globulus (Fitch). The galls were collected 

 by A. T. Packard at Providence, R. I., and were received at Wash- 

 ington, D. C, on April 7, 1863. I have one male from Doctor Kinsey 

 reared by A. F. Leach, Diablo, Calif., in 1923, from the galls of 

 D. eldoradensis var. on Quercus lohata; and from the same oak, at 

 Cottonwood, Calif., two females and a male from undetermined galls; 

 also a female and two males that I reared from the galls of D. glob- 

 ulus (Fitch) on Q. alba between May 1 and 15, 1923, at Urbana, 111. 

 Three females and a male were obtained from the galls of Biorhiza 

 forticornis (Walsh) by L. H. Weld (No. 36) at Evanston, 111. Two 

 males (Hopk. U. S. 13685 ^) were reared by William Middleton at 

 Falls Church, Va., April 5 and 12, 1918, from the galls of D. globulus 

 on Q. alba. The same lot of galls contained D. varians Walsh, 

 D. dubia Walsh, and D. dAibia var. rufosa Balduf. 



The following are additional Hopkins lots : A female and 3 males 

 (Hopk. U. S. 15637 ^) , reared October 2, 1922, by L. H. Weld, Tijeras, 

 N. Mex., from galls of Disholcaspis sp. undescribed, on Q. pungens; 

 2 females (Hopk. U. S. 15637^), same locality and oak, by Weld, 

 from gall of Andricus tecturnarum Kinsej'^; a male (Hopk. U. S. 

 15637^), reared June 1, 1922, Las Vegas, N. Mex., from galls of 

 CalUrhytis ruglnosu^ (Bassett) collected on various oaks; a female 

 and 3 males (Hopk. U. S. 13686 «), reared by L. H. Weld, April 5, 

 1918, from galls of Disholcaspis spongiosa Karsch, on Q. stellata at one 

 or more of the following localities : Thebes, Liberty County, Ga., or 

 Palestine, Trinity, or Houston, Tex.; 1 female (Hopk. U. S. 10777"), 

 reared by S. A. Rohwer, May 14, 1919, Poplar Bluff, Ariz., from galls 

 on Q. stellata; and a pair (Hopk. U. S. 10777''), same collector, 

 locality, and oak, May 14 and 21, 1919, with no cynipid record. 

 There is also a lot of 2 females and 9 males (Hopk. U. S. 1365 »), 

 reared by F. R. Herbert, February 26, and April 5 and 24, 1918, at 

 Los Gatos, Calif., from galls of Disholcaspis sp. on Q. chrysolepis. 



I sometimes have difficulty in distinguishing between this species 

 and dubla Walsh. D. globuli Balduf may represent the smaller,
