Dryophanta pulchripennis, new species

Gall.--The specimens of the gall from which this species was reared can not now be found in the collection, but the following description of it may assist in its identification:

from Arizona, a leaf of an undetermined oak with six galls on its under surface; four of these are in a row in the middle between the midrib and the margin; they are light brown, almost hemispherical, subopaque, reticulate, and with scattered, very minute, reddish tubercles, which have some short white hairs basally.

Reared during April, 1881

Diplolepis pulchripennis

Described as from Quercus undulata, the writer has collected galls and reared flies which agree with the type on Q. undulata and grisea and collected what seem to be the same galls on arizonica, oblongifolia, 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 Mountains 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 collected 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.

Ball-gall wasp

Hosts: Quercus arizonica, oblongifolia, turbinella, toumeyi, rugosa

Galls measure 3-4 mm in diameter, occur singly--not in clusters--but may be in distinct rows on either side of the midrib, with space between each gall and the next.
