GALL. — As described for the species, apparently indistinguishable 
from the galls of other varieties of this species and of Cynips dugesi. 
On Quercus grisea, Q. undulata, Q. undulata var. pungens ( = Q. 
wrightii) , Q. Gambelii, Q. Toumeyi (acc. Weld), Q. oblongifolia, Q. 
arizonica, Q. diversicolor (acc. Weld; =Q. reticulata), and probably 
related oaks. Figure 263. 
RANGE. — New Mexico: Magdalena ( Q . grisea, Weld inch Kinsey 
coll.). Blue Canyon near Socorro, Abo Pass (in Sandia Mts.?), Nogal 
Canyon, Burro Mountains, Fierro, and Tijeras (galls, acc. Weld 1926). 
Near Alamogordo at 7000 ft. ( Q . arizonica, also galls on Q. undulata, 
Kinsey coll.). Highrolls (galls, Q. undulata, Kinsey coll.). Mountain 
Park (galls, Q. undulata var., L. H. Bridewell in Kinsey coll.). Hills- 
boro ( Q . grisea, Kinsey coll.). Kingston (galls, Q. grisea and Q. Gam- 
belii, Kinsey coll.). Organ Mountains (R. R. Larkin, Q. Wrightii; 
maculipennis types). Soledad Canyon in Organ Mountains ( Q . arizonica, 
L. H. Bridewell in Kinsey coll.). 
Arizona: Prescott ( Q . grisea, Kinsey coll.). Safford, Oracle, 
Courtland, Fort Huachuca, and Bisbee (galls, Q. arizonica, Kinsey coll.). 
Tucson (= Santa Catalina Mountains? Cox coll., bella types). Sabino 
Trail in Santa Catalina Mountains and Santa Rita Mountains ( Q . ob- 
longifolia, Q. arizonica, Kinsey coll.). Tumacacori Mountains, Patagonia 
Mountains, Chiricahua Mountains, Mule Mountains, and Nogales (galls, 
acc. Weld 1926). 
Probably confined to the desert mountain ranges of more southern 
New Mexico and Arizona (and adjacent Mexico?). Figure 45. 
TYPES. — Of bella: Holotype female, paratype female, and galls at 
the Philadelphia Academy; one female at the U.S. National Museum; 
galls at the American Museum of Natural History. From Tucson 
(probably the Santa Catalina Mountains), Arizona; host unknown; E. 
T. Cox collector. 
Of maculipennis: 1 female and fragments of a gall in the U.S. 
National Museum. From the west slope of the Organ Mountains, New 
Mexico; on Q. Wrightii (= Q. grisea var.) ; T. D. A. Cockerell collector. 
All of the type material of both bella and maculipennis was exam- 
ined in making the present re-descriptions. 
This is the most widespread variety of the species. The 
oak-inhabited mountain ranges of this part of the Southwest 
are isolated by broad deserts, but the available insect material 
does not show variation enough (unless in the size of the 
areolet) to warrant a distinction of varieties in this whole 
area. Weld, however, records galls from Hackberry, Ash- 
fork, and Williams in Arizona, and these more northern locali- 
ties may represent some other, as yet undescribed variety if 
the distribution of this insect agrees with that of most of the 
other Cynipidae of Arizona. The material from the Apache
