and reticulata. Galls were seen in the Santa Catalina Mountains at 

 Oracle and in Sabino basin, in the Santa Rita, Tumacacori, Pata- 

 gonia, Huachiica, IViiile, and Chiricahna Mountains, and at Xo^ales, 

 Bisbee, Prescott, Hackberry, Ashfork, and Williams, Ariz. In New 

 Mexico they were seen in the Burro Mountains, at Fierro, Kingston, 

 Hiilsboro, Nogal Canyon, Magdalena, Blue Canyon near Socorro, 

 and in Sandia IMountains at Abo Pass and Tijeras. The galls were 

 nearly full grown on arizonica in the Huachucas on July 9, and at 

 Hackberry on undulata contained pupae on October 6. At Tijeras 

 they were common on undulata^ and on November 1 contained adults 

 just beginning to emerge. A lot of flies cut out on that date lived 

 in a pill-box without attention until December 30, and three were 

 still living on January- 12. Few of the galls were parasitized here. 

 In the Chiricahuas only six adults were secured by opening G5 galls, 

 and in the Santa Ritas only one in fifty contained a producer. 



DIPLOLEPIS BREVIPENNATA (Gillette) 



This species, Avhose type locality is Manitou, Colo., seems to be 

 very common on all the oaks in the region of the Spanish Peaks, 

 It occurs on every type of oak found about Las Vegas Hot Springs, 

 and extends as far south as the Sandia Mountains. In the Garden 

 of the Gods on October 4, 1921, galls on Quercus gamhelil contained 

 both pupae and adults. At Wetmore the galls were common, and 

 on October 6 contained adults ready to emerge which were found 

 dead (and others living) in the box when the material was ex- 

 amined on December 31. Galls sent to Washington (Hopkins U. S. 

 No. 15635«) gave flies October 31, November 15, and January 10. 

 At the Alvarado ranger station near West Cliff the galls were rare. 

 Adults were chewing out of the inner cell at La Veta on October 10 

 and could be found among the fibers. At Trinidad galls were seen 

 on Q. fendleri. In New Mexico the galls were seen at Raton, Wagon 

 Mound, Shoemaker, Glorieta, and at Tijeras a few occurred on 

 fendleH and gnsea and one gall was found on the same bush of 

 undulata that bore the similar galls of a fully-winged species Diplo- 

 lepis hella (Bassett). This is the most southern point where the 

 Avriter found the one and the most northern locality for the other.
