19, 20, and 28, 1922, and Avhen some of the galls were cut open the 

 next July a few contained larvae indicating that the emergence of 

 the species is probably distributed over two seasons.. 



Similarly affected acorns were observed on the middle fork of 

 the Kaweah Eiver in Sequoia National Park, on Mount St. Helena, 

 on Mount Diablo, at Los Gatos, in California Redwood Park, in 

 Palo Colorado Canyon in the Santa Lucia Mountains, at Camp 

 Baldy in the San Gabriel Mountains, in Waterman Canyon in the 

 San Bernardino Mountains, at Idylhvild in San Jacinto Mountains, 

 and on trail to Santiago Peak in the Santa Ana Mountains.

Galls of this species were collected on the Capitol Grounds at 

 Washington on Q. phellos by J. C. Crawford. They were beginning 

 to drop on May 4. He reared adults April 23, 1910. The writer 

 collected galls from a tree of Q. palustris on the Smithsonian grounds 

 on. May 16, 1920. Flies emerged April 10, 1921. 



Galls have also been collected on Q. phellos at Clarendon and 

 Cherrydale, Va. ; Anniston, Livingston (J. W. A. Wright), and 

 Montgomery, Ala.; and Rome (U. S. D. A. 5733), Ga.; and Tupelo

 deum, and abdomen black; antennae, sides of pronotum, rest of 

 mesoscutum, disk of scutellum, and legs reddish-brown, much lighter 

 in specimens cut out of gall in fall and killed at once than in those 

 that emerged naturally in out-of-door breeding cage in spring. 

 Head from above as broad as thorax, cheeks scarcely broadened 

 behind eyes, vertex coriaceous ; from in front transverse, interocular 

 space .53 transfacial and area one and one-tenth times as broad 

 as high, malar space .4 eye, antennae 13-segmented, lengths as 

 (scape) 11 : 7 : 16 : 14 : 11 : 10 : 8 : 7.5 : 7 : 6 : 6 : 6 : 11, malar space faintly 

 rugose, face and genae pubescent. Pronotum pubescent. ]\Iesonotum 

 with tawny appressed pubescence not dense enough to hide sculp- 

 ture, lateral and parallel lines bare. Mesoscutum smooth and shin- 

 ing between the punctures, the parapsidal grooves deep, smootli, nar- 

 rowing in front and not reaching as grooves much over half-wa}^ to 

 pronotum. Scutellum rugose behind with slight tooth on each side, 

 disk smoother with two distinctly separated smooth transverse pits 

 at base. Carinae on propodeum slightly converging above, inclos- 

 ing a smooth area broader than high, spiracular areas pubescent. 

 Wing pubescent and ciliate, veins not heavy, second abscissa of 

 radius not quite angled, radial cell three and one-half times as long
