DIPLOLEPIS PULCHRIPENNIS (Ashmead) 



Described as from Quercus unduJata^ the writer has collected 

 galls and reared flies which agree with the tj^pe on Q. undulata and 

 grisea and collected what seem to be the same galls on at'inonica, 

 oblonf/ifoUa, toumeyi, and reticulata. Galls were collected at the 

 "breaks" south of Bard (PI E. Goddard), Wagon Mound, Las 

 Vegas Hot Springs, Glorieta, Tijeras, and Abo Pass in the Sandia 

 Mountains, near Socorro, Magdalena, Nogal Canyon, Hillsboro, 

 Kingston, and in the Burro INfountains in New Mexico; at Williams, 

 Prescott, Oracle, Patagonia, and in the Santa Rita and Chiricahua 

 Mountains in Arizona. At Las Vegas Hot Springs galls were col- 

 lected on October 17 when flies were just beginning to emerge. A 

 lot were out and had died by January 2 and a few more emerged 

 by January 13. 



DIPLOLEPIS RYDBERGIANA (Cockerel!) 



The type fly and gall of this species are in the National Museum. 

 The writer collected galls at the type locality. Las Vegas Hot 

 Springs. N. M., in October, 1921, and cut out living flies January 2. 

 Galls sent east for rearing gave flies December 31, January 4, 20, 

 February 1 and 6, the flies coining out in largest numbers on last 

 date. From galls collected at Shoemaker on October 23, 1922, flies 

 emerged and were alive on February IG, 1923. Galls were collected 

 at Wagon ]Mound also. They are saddled on the midrib on the 

 under side of the leaf. The type fly measures 2.8 mm. The series 

 of reared specimens ranges from 2.5-3.8 mm. Average of 88 speci- 

 mens, 3.1G mm.
