1911] Cynipidce of California 355 



from pubescence. Cheeks full, bulging. Antennas 14-jointed, filiform, 

 the 3rd joint slightly larger than 4th and narrowed toward base, the 

 apical joint twice as long as the preceding, fusiform. Parapsidal 

 grooves distinct, a more or less distinct medial groove and distinct 

 grooved lines on the shoulders. Scutellum rugose, with two large 

 foveas at base, separated by a carina; pleura anteriorly slightly rugose, 

 posteriorly nearly smooth, with some very delicate striae. Abdomen 

 smooth, with a few hairs on the side of second segment; the terminal 

 segments show a fine, delicate punctuation; the spine of the ventral 

 valve is long. Wings hyaline, except the entire apical third, which is 

 smoky or dark brown, the veins stout, black, the angular projection in 

 marginal cell at base being very distinct. 



"Type. No. 3067, U. S. N. M. 



"Three specimens, reared by Mr. Albert Koebele, form galls collected 

 in Sacramento County, California, but the year of collecting and the 

 date of rearing are not given. A single specimen (No. 3714) was reared 

 February 17, lS.Xli. The bright red o>lur and smoky liases of wings will 

 readily distinguish the species." (W. H. Ashmead). 



I have not seen examples of this species.

Female. Black, antennas, legs, mandibles and abdomen vcntrally 

 dark brown. Head coarsely rugose, antennas 14-15 segmented, 1st and 

 2nd segments stout, 3rd segment longest, a little longer than 4th, suc- 

 ceeding segments to 9th progressively shorter, 9th and following seg- 

 ments subequal, 15th a mere tip on preceding segment. Thorax 

 coarsely rugose, parapsidal grooves distinct, complete, median longi- 

 tudinal lines reaching half-way to posterior margin, scutellum rugose, 

 with subcircular basal foveas shallow, smooth and shining at bottom, 

 not exactly approximate. Abdomen more or less smooth and shining, 

 2nd segment occupying about two-thirds its length, ventral valve and 

 sheath of ovipositor pubescent. Legs clothed with pubescence. Wings 

 hyaline, radial cell open at the margin, a black cloud at base, subcostal 

 vein scarcely reaching margin, vein at base of radial cell angulate, areolet 

 distinct, cubitus not always reaching basal vein. Length 3 mm. 



Gall. Yellowish, subspherical galls, about 35 mm. in diameter, 

 the surface more or less roughened by slight elevations in the form of 

 longitudinal ridges, containing within numerous oval larval cells im- 

 bedded in the pithy substance of the gall. 



Habitat. Stanford University, Cal. (R. W. Patterson.)
