the same host at Hillsboro, the flies cut out November 16. Paratypes 

 also are from Prescott, Ariz., (host not recorded), the galls collected 

 April 13, 1918, the flies emerging before April 20 (Hopkins U. S. 

 No. 15617/i;). The galls have been collected on Q. undulata at the 

 '• breaks " south of Bard, N. Mex., (E, E. Goddard), and at Ashfork, 

 Ariz. The writer has collected what he takes to be galls of this 

 species on Q. grisea at Magdalena, N. Mex.; on Q. arizonica ai 

 Bisbee and Oracle, Ariz. ; and on Q. ohlongifolia at Nogales, Pata- 

 gonia, and in Huachuca and Santa Catalina Mountains, Ariz. 



DIPLOLEPIS ATRIMENTA (Kinsey) 



This species was described from imperfect specimens from galls 

 on Q. douglasii from Three Rivers and Redding, Calif. The writer 

 has collected the galls on two other California oaks also: on Q. 

 douglasii at Three Rivers, Kaweah, Bagby, Placerville, Oroville, 

 Red Bluff, Shasta, Ukiah, Lakeport (flies emerging May 12), 

 Cloverdale, Calistoga, St. Helena, Mt. Diablo, Stanford Uni- 

 versity (flies emerged May 1-8), Los Gates, Paraiso Springs, Brad- 

 ley, Jolon, Paso Robles (flies emerged April 25), Santa Margarita, 

 and Lebec; on Q, lohata at Los Gatos, Stanford L^niversity, Lake- 

 port, and Red Bluff; on Q. dumosa at Paso Robles, Jolon (flies 

 emerged April 25) and Paraiso Springs. The galls are sometimes 

 attached to the staminate flower axis as well as to leaves. 



Miss Egbert reared adults of this species in April, 1917, and in- 

 cluded a description in her manuscript thesis presented at Stanford 

 L^niversity in May, 1917. 



DIPLOLEPIS BELLA (Bassett) 



Cynips bella Basseix Canad. Ent., vol. 13, ISSl, p. 93. 



Holcaspis macuUpennis Gillette, Canad. Ent., vol. 26, 1894, p. 236. 



H. 77iaculipe7inis was described from a single specimen from the 

 west slope of the Organ Mountains in New IMexico. Without seeing 

 this type Beutenmueller and Fullaway have erroneously determined 

 a large oak apple on Quercus garryana from Oregon and northern 

 California as this species. This has since been described as Cynips 

 mirahilis Kinsey (see p. 64). The writer has compared the Gillette 

 holotype of macuUpennis with a Bassett type of hella in the National 

 Museum and finds they are the same. Because of the percurrent 

 parapsidal grooves and very oblique hind margin of the second 

 tergite Mayr, in 1881, placed the species in Dryophanta — now knoAvn 

 as Diplolepis. 



This species, described from an unknown oak from Tucson, Ariz., 

 has been reared by the writer from galls on Quercus arizonica^ 

 toumeyi^ grisea^ and undulata, and the galls found on ohlongifolia
