51 



FEMALE. — Median groove evident in part; parapsidal grooves con- 

 tinuous; abdomen hairy on the sides of all the segments; almost a score 

 of spots in the cubital cell; length about 4.5 mm. HEAD: Not as 

 broad as the thorax, considerably widened behind the eyes; brownish 

 rufous, darker on the median elevation and piceous on the mandibles; 

 finely rugose, mostly hairy, dense with long, yellowish hairs on the 

 face, naked on the front. Antennae deep brown, tinged with rufous on 

 the first two segments; hairy; with 14 segments, the first segment almost 

 as long as the fourth, the second segment globose, the third consider- 

 ably longer than the fourth, the last distinctly longer than the pre- 

 ceding. THORAX: Bright rufous, black between the parapsides except 

 posteriorly, and black about the lateral lines; mesonotum smooth, finely 

 punctate, not heavily covered with long, yellow hairs; parapsidal 

 grooves continuous, distinct to the pronotum, rather well convergent 

 posteriorly, only gradually divergent anteriorly; median groove dis- 

 cernible for almost half the length of the mesonotum, quite distinct 

 posteriorly; anterior parallel lines fine but evident, most distinct and 

 smooth and divergent posteriorly, extending half way to the scutellum; 

 lateral lines very prominent, broad, elevated, smooth, and naked; scutel- 

 lum wide, but considerably longer than wide, rounded posteriorly, rich 

 rufous, finely rugose, sparsely hairy, dense with yellow hairs at the 

 sides, with a slight indication of a longitudinal, median depression as 

 in the genus Amphibolips; basally with two very large foveas, black, 

 shining, deeply grooved, indistinctly separated by irregular ridges; pro- 

 notum at the sides rich rufous, smooth, finely punctate, sparsely hairy; 

 mesopleurae rufous with some black, punctate, hairy, densely so ventrally. 

 ABDOMEN: Longer than wide, the segments only slightly produced 

 dorsally, rufous to rufo-piceous and black, darkest dorsally and ventrally, 

 practically smooth tho very microscopically punctate, more distinctly 

 punctate where hairy, a heavy coating of yellowish hairs on the sides 

 of all the segments, a tuft of long, yellow hairs on the tip of the ventral 

 spine. LEGS: Femora rufous, coxae yellow rufous, tarsi and tibiae 

 rufous brown; punctate, dense with yellow hairs, hairs only sparse on 

 the femora; tarsal claws heavy, toothed. WINGS: Tinged with yel- 

 low, veins yellowish brown, cross-veins darker; areolet large; radial 

 cell open, the second abscissa of the radius not reaching the margin, 

 curved, thickened, and peculiarly knobbed terminally; the first abscissa 

 sharply angulate but without a projection, infuscated, as is also the 

 subcosta terminally; light brown clouds in the cubital and discoideal 

 cells, about a score of distinct, brown spots in the cubital cell, LENGTH : 

 4.5-5.0 mm. 



GALL. — Globular leaf gall; monothalamous; 15.-35. mm. in diam- 

 eter, thin-shelled, smooth, yellov/ish brown, rather closely marked with 

 irregular, purplish brown spots. Internally with a hard-shelled larval 

 cell, 3. X 5. mm., held centrally by a moderately dense mass of silky, 

 sparingly branched fibers. On leaves of Quercus garnjiuia. 



RANGE. — Washington: White Salmon. Oregon: Ashland, Junc- 

 tion City, Grants Pass, Roseburg, Canby; Portland (E. 0. Hovey) ; 

 Albany (Trotter). California: Ukiah(?), Yreka; McConaughy, Siski- 

 you Co. (Fullaway) ; Elsies Creek, Amador Co. (G. Hansen, in Gray
