galls November 4, 1918; insects November 11, 1919, and January 15, 
1919; Q. Gambelii; J. H. Pollock collector. 
The present re-description is made from all of the types, com- 
pared with my material from northern New Mexico. 
This is the southern Rocky Mountain variety of the species, 
a short-winged insect replaced in the southern two-thirds of 
New Mexico and Arizona by the long-winged acraspiformis, 
but in Utah by the short-winged calvescens. The material 
collected by Frederick Cogshall near Raton, New Mexico, was 
full-sized late in July (1926), and the larva was large enough 
to complete development in spite of a prolonged drying to 
which its gall was subjected before reaching our laboratory. 
This insect emerged out-of-doors at Bloomington, Indiana, on 
December 18 (1926). The galls of the type material were 
collected at Colorado Springs on November 4 (1918), one adult 
emerging on November 11 while others were found alive in the 
breeding cage on the following January 15.

Figures 59, 307-308, 366, 408 
FEMALE. — Close to the varieties alaria and villosa. Generally 
bright rufous with much dark rufous and piceous black; the head dis- 
tinctly wider than the thorax, very finely, irregularly rugose; the thorax 
much reduced, half again as long as wide; the parapsidal grooves very 
fine or nearly obliterated, extending at most half way to the pronotum; 
scutellum rather smooth with a not heavy punctation, anteriorly de- 
pressed to form the undivided, poorly defined foveal groove; the ridge 
between the scutellum and the rest of the mesonotum only very poorly 
indicated; mesopleuron punctate and very hairy; abdomen enlarged, 
rather elongate, largely hairy but naked in many spots on the second 
segment, naked on the basal half of the exposed portion of the third 
and fourth segments, and naked over a distinctly wide area on the 
whole abdomen dorsally; the second segment covering a half to two- 
thirds of the whole abdomen; the wfings much reduced but relatively 
broad, distinctly longer than in either of the varieties alaria or villosa, 
averaging 0.34 of the body in length, with a fairly complete venation in 
the basal half of the wing; length 2.8 to 4.0 mm., averaging nearer 3.3 
mm. Figures 366, 408. 
GALL. — Mature gall straw-yellow in color, up to 14.0 mm. in diam- 
eter, the spines up to 2.5 mm. in length, rather flexuous, slender, the 
whole gall appearing as a mass of coarse and tangled hairs; on the 
leaves of Quercus utahensis (and related oaks?). Figures 307-308.
