FEMALE. — Generally rich, dark rufous, darker to rufo-piceous in 
places, almost black on the thorax anteriorly between the parapsidal 
grooves and about the lateral lines, the abdomen rufo-piceous, the legs 
mostly rufous but darker to rufo-piceous on the coxae ; mesonotum 
posteriorly punctate with a distinctly coriaceous surface between the 
punctations, anteriorly rugoso-punctate ; parapsidal grooves quite ob- 
scure anteriorly; scutellum rather roughly rugose; mesopleuron smooth 
and shining between the punctations but everywhere finely, shallowly 
punctate; the sides of all the segments of the abdomen sparsely hairy, 
the second segment with heavier patches of hair antero-laterally ; in- 
fuscation on the first abscissa of the radius prominent, extending more 
than a third the length of the radial cell, part of the infuscation almost 
as dark as the vein itself; the enlargement at the tip of the second 
abscissa of considerable size, extending parallel to the margin of the 
wing and entirely to one side (toward the tip of the wing) from the 
radius; areolet large to remarkably large; smoky patches in the cubital 
cell very large, filling a large part of the apical third of the cell, usually 
fused; a large and heavy insect, 3.5 to 4.0 mm. in length. Figure 397. 
GALL. — The core straw to dirty brown in color, the hair-like spines 
whitish at base but for the most part rich wine-purple, fading to pur- 
plish pink; the bases of the spines somewhat swollen; on leaves of 
Quercus arizonica and Q. oblongifolia (and Q. Toumeyi ?) . 
RANGE. — Arizona: Santa Rita Mountains ( Q . arizonica , Q. ob- 
longifolia, Kinsey coll.; also acc. Weld 1926). Courtland and Fort 
Huachuca ( Q . arizonica, Kinsey coll.). Whetstone (galls, Q. arizonica, 
Kinsey coll.). Ramsay Canyon in Huachuca Mountains ( Q . arizonica 
and galls on Q. oblongifolia, acc. Weld 1926). Patagonia ( Q . arizonica, 
Q. Toumeyi, and galls on Q. oblongifolia, acc. Weld 1926). Tumacacori 
Mountains, Bisbee, and Chiricahua Mountains ( Q . arizonica, acc. Weld 
1926). Mule Pass Mountains (E. T. Cox, types). Nogales (galls, Q . 
oblongifolia, acc. Weld 1926.) 
Known only from Arizona south of Tucson, probably in the moun- 
tains of southwestern New Mexico. Figure 58. 
TYPES. — 3 females and galls in the Philadelphia Academy. 1 fe- 
male in the U.S. National Museum. From the Mule Pass Mountains, 
Arizona; Q. arizonica (?) ; November, 1879; E. T. Cox collector. 
The present re-descriptions are based on the holotype and all the 
paratypes, and on material from other localities in southern Arizona. 
The type material of nubila was collected in November. 
Weld collected galls in December and bred adults on January 
2 and 13, and February 6 and 10. From the galls I collected
