Female. Pale yellowish brown, the antenna? distally from H )ih 

 segment and abdomen dorsally fuscous to black, eyes, ocelli, tips of man- 

 dibles, presternum, metathorax, tips of tarsi and ventral valve black. 



Head faintly rugose, almost granulose, face pubescent, antenna 1 I 

 mented, filiform, 1st and 2nd segments stout, 1st obconic, 2nd oval, 3rd 

 est, as long as 1 and 2 together and a little longer than 4th, 

 succeeding segments to 9th progressively. shorter, 9th-13th subequal, last 

 ent longer than penultimate by a half. Thorax elevated, subspher- 

 ical, pronotum narrow in the middle, granulose, slightly pubescent, 

 mesonotum reticulate, almost shagreened, parapsidal grooves di 

 impressed, not quite complete but approaching anterior margin, median 

 longitudinal lines reaching half-way to posterior margin, smooth lines 

 over base of wings long and very distinct, pleura largely granulose, 

 slightly pubescent above and beneath, aciculate in the middle, scutellum 

 granulose, pubescent, basal fovea' large, oval, transverse, and shallow, 

 with smooth, shining bottom, approximate, metathorax shallowly 

 punctate, pubescent. Abdomen long oval, smooth and shining, 2nd 

 segment occupying about half its length, 3rd and 4th segments rather 

 succeeding segments narrow, posterior margins in all oblique, 

 ovipositor sheath exserted, pubescent. Wings hyaline, pubescent, 

 veins pale brown, radial cell long, narrow, open at the margin, vein at 

 base angulate, areolet distinct, cubitus not reaching basal vein.

( rail. Moderately large, brownish, hard, globular galls, about 

 10 mras, in diameter, on twigs of Quercus agrifolia, surface microscopic- 

 ally pubescent. Internally composed of a dense, cork-like substance, 

 in which the single larval cell is imbedded. 



Habitat. Palo Alto, Cal. (R. W. Patterson.)

 dorsally darker, head and thorax pubescent. Head faintly rugose, 

 antennas 14-segmentcd, 1st segments obconic, 2nd 1< ing i »val, 3rd segment 

 >t, as long as 1 and 2 together and incised proximally for two-thirds 

 its length, succeeding segments to 9th progressively shorter, 9th and 

 following segments, which are fuscous, subequal, except last, which is 

 longer than penultimate. Thorax closely punctate, punctation rather 

 coarse, parapsidal and median grooves from posterior margin distinct, 

 the former almost complete, median longitudinal lines reaching nearly 

 half-way to posterior margin, smooth lines over base of wings rather 

 long, scutellum flat, closely punctate, basal fovea? transverse and not 

 separated by a carina. Abdomen smooth and shining, 2nd segment 

 occupying less than half its length, pubescent at base, 3rd, 4th and 5th
