1911] Cynipida of California 343 



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

 and broad, mesopleura and scutellum punctate, basal foveas on latter 

 obsolete. Abdomen compressed, dorsally bare, smooth and shining, 

 ridged apically, pubescent at sides and beneath, 2nd segment occupying 

 about one-half its length, 3rd tergite distinct, only sternites of following 

 segments visible, dorsal and ventral valves prominent and pubescent. 

 Wings hyaline, pubescent, veins prominent, radial cell open at margin, 

 vein at base angulate, areolet large, cubitus not reaching basal vein. 

 Length, 4 mm. 



Gall. Brownish, globular galls, about 10 mm. in diameter, occur- 

 ring singly or in clusters on the twigs i if Quercus douglasi. Sometimes a 

 little irregular in shape, not much roughened, and covered with a 

 yellowish brown fuzz. Monothalamous, with a large, globular larval 

 chamber, quite distinct from the cortical layer and held in place by 

 loose, spongy tissue. 



Habitat. Hornitos, Cal. (Miss Hazel Engebretsen).

 Cynipida- (1910), p. 377. 



Female. Very similar to C. canescens, but the pubescence is regularly 

 more extensive on abdomen, only a small rhomboidal area dorsally on 

 second segment remaining bare. The antenna? are brownish through- 

 out, the basal segments darker, but light at the joints. The abdomen 

 is not compressed apically but rotund, and all the tergitcs are visible. 



Gall. Pale yellowish, globular galls, about 12 mm. in diameter, 

 found on the twigs of Quercus douglasi. The galls are pointed at the 

 poles and the surface is roughened by irregular ridges, or bears short, 

 blunt tubercles giving it the appearance of coral. 



Habitat. Mt. Diabalo, California. (Harold Morrison.) 



Cynips multipunctata (Beutenm.) . 



Dryophanta multipunctata, Beutenmuller, Ent. News, vol. 22 (1911), p. 67. 



Female. Reddish brown, eyes, ocelli, tips of mandibles, face medi- 

 ally, pecten, dorsal and subdorsal vittae on mesonotum concurrent with 

 median longitudinal lines and lines over base of wings, abdomen dor- 

 sally, sometimes entirely black or blackish. Head broad, bulged 

 beyond the narrow eyes, faintly rugose and punctate, with a thick 

 covering of pale yellowish pubescence, antennas 14-segmented, 1st and 

 2nd segments brown, following segments brownish black, 1st to 4th 

 segments light brown distally, 1st and 2nd segments as usual stout, 

 3rd segment longest, longer than 1 and 2 together and a trifle longer 

 than 4th, the following segments progressively shorter except the last, 

 which is one-third longer than penultimate. Thorax faintly rugose 

 and punctate, pubescent, except on median longitudinal lines which 

 are bare, parapsidal groqves complete, median longitudinal lines reach- 

 ing more than half-way to posterior margin, smooth lines over base of
