1911] CynipidcB of California 347 



"Gallfly. Female. Length, 3 to 5 mm. Reddish brown, antennae 

 and legs brownish yellow, eyes and abdomen dark, reddish brown. 

 Head and thorax closely punctate, sparsely pubescent. Antennae 

 14-jointed, very slightly thickened at tips. The thorax, besides the 

 two parapsidal grooves, which are obsolete anteriorly, has a median groove 

 extending anteriorly for more than half length of the mesonotum, two 

 short median grooves anteriorly on each side of this, and the usual 

 groove on the shoulders. Scutellum cushion-shaped, rugose, the 

 fovea? distinct, pleura finch', minutely rugose, slightly striated at base. 

 Abdomen polished, the short apical segments under a high power 

 show a fine, delicate punctuation,' while the ventral valve projects but 

 slightly. Wings glossy, hyaline, veins yellowish, areolet small; neither 

 the apex of the submarginal nor the radial vein reach the margin. 



"Types No. 30G6, U. S. N. M. 



" One female, reared from a gall found on Quercus chrysolepis, at 

 Colfax, Placer County, California, October 8, 1885, by Mr. Albert 

 Koebele; and two specimens reared January 18 and 29, 1886, from 

 same galls. Other of the galls are numbered 3S10 U. S. N. M." (W. H. 

 Ashmead.) 



I have not seen examples of this species.

"Gall. An irregular, rugose, yellowish brown woody swelling, 

 containing numerous cells, growing apparently from the extreme tips 

 of very slender twigs of Quercus chrysolepis, the gall appearing to have 

 a long peduncle, or it may be at the apex of the petal of a leaf, the leaf 

 in consequence being aborted. The gall is more or less contracted in 

 the middle and varies in length from 2-4 cm. and in diameter from 

 1-2 cm. 



"Gallfly. Female. Length, 2 mm. Pale brown or brownish yellow, 

 the eight terminal antennal joints, the middle and posterior tibiae, 

 metathorax, abdomen dorsally, and wing veins brown. Head and 

 thorax closely, uniformly punctate. Antenna? 14 or 1.5-jointed, depend- 

 ing upon whether the terminal joint, which presents a rather distinct 

 suture, is counted as one or two joints. The terminal joints all appear 

 delicately fluted. Mesonotum has three distinct grooves, extending its 

 whole length, and the groove on the shoulder is long. Scutellum 

 minutely rugose, the fovea? oblique, distinct, but rather widely sep- 

 arated. Wings hyaline, wdth short pubescence. 



"Type. No. 3068 U. S. N. M. 



"Seven female specimens, received from Prof. E. W. Hilgard, 

 Oakland, California, and reared November 10, 1876. The gall also 

 occurs on Quercus agri folia, and Prof. Riley says "a woody deformation 

 of the stamniate aments and quite abundant on some trees." (W. H. 

 Ashmead) .
