Mvi: 10 GALL-INHABITING CYNIPID WASPS WELD 83 



Gall (fig. 19). — A midrib cluster of a few galls on under side 

 of leaf in fall, dropping to ground when mature. The individual 

 galls are nearly globular, up to G nun. in diameter, dark red in 

 color, covered with short blunt tubercles, have a scar at apex and are 

 drawn out at base into a short pedicel. Monothalamous. 



Ilahitat. — The type material was collected at Hoxie, Ark., October 

 10, 1917. Two adults issued April 11. 1920, and both larvae and 

 pupae were found inside of galls opened October 10, 1920, indicating 

 that the emergence is distributed over at least three seasons. Galls 

 were seen also at Texarkana and at Poplar Bluff, Mo. 



ANDRICUS SALTATUS Ashmead 



Described from Q. clnerea from '" Florida," the writer collected 

 galls like the ty]:»es at Jacksonville and Ocala in April on Q. ruhra^ 

 the Spanish oak. but failed to rear adults. 



ANDRICUS SINGULARIS (Bassett) 



These galls on red oak, (J. tna.rimn, were collected at Evanston. 

 Glen EUyn, and Willow Springs, 111.: Delevan (D. Watt), Wis.: 

 North East, Pa.: Medina and Ithaca, X. Y. : Bluemont, Alexandria, 

 and Bedford County, Va. At Medina adults issued July 3. HM-l. 

 Brodie found the galls at Toronto and says the flies are usuallv 

 all out by the middle of July but in 1891 they emerged July 14-27, 

 males appearing first. Middleton reared flies July 6 from galls 

 collected at Phnnmer Island, Md. 



ANDRICUS SPECTABILIS Kinsej 



Tliis species was described from Q. clwi/solepis. The Avriter has 

 collected galls on Q. tnhoxli in the Santa Catalina and Chiricahua 

 Momitaiiis, Ai-iz., Avhere on November 28, 1921, the galls on the cur- 

 rent year's wood wei-e but partly grown and those on 1920 wood 

 still without exit holes but containing living adults. The writer 

 collected galls on Q. chr>/solej/is in Waternum Canyon in the San 

 Bernardino .Mountains on March IS, 1922, and cut out living adults 

 ai-paivntly nearly ready to emerge. Other nearly full-grown galls 

 contained much nutiitive material in the cells and small larvae. 

 Galls on rhr//solej>Ls were collected at Idyllwild, in Santa Ana 

 iiange, on Mount Lowe (J. ^Martin), in Sequoia National Park, in 

 Fresno County on Horse Corral tiail, in Yosemite National Park 

 (J. C. Bradley), Placerville, Kyburz, Pulga, in Santa Lucia Range,
