Quercus reticulata [rugosa], gambelii, subturbinella [turbinella]
Leaf galls
Integral
Many-celled midrib thickening, 19 by 10 mm, South Utah on same oak as sileri above.

Neuroterus quercicola variety pubescens, new variety
agamic form

GALL. — As described for the species. A moderate-sized mid-vein or petiole swelling, woody, packed densely with larval cells, covered with a bluish gray, dense, short pubescence; on leaves of Quercus grisea.

RANGE. — Arizona: Globe, Safford. Probably confined to the mountain country just south of the Colorado Plateau.

This gall is rather distinct from others of the species in its coat of bluish gray pubescence. It is of interest as an agamic generation in a leaf gall; the only other agamic form known inhabits twigs or acorns, but the evergreen leaf of the host of the present variety allows the fall and winter form to survive on the leaf. This form may also occur in twigs with or without producing a gall. The bisexual form probably occurs in a similar gall on the leaf.

Neuroterus quercicola variety quercicola
bisexual form

GALL. — Typical for the species; a leaf midvein swelling; on Q. Gambelii.

RANGE. — Utah: a southern part (Bassett); Salt Lake City (thru C. T. Dodds) . Probably confined to a region in Utah.

Weld's galls, collected on July 2, 1911, gave adults July 30. This is considerably later than the March and April emergence of variety pacificus further south, and shows the considerable dependence of cynipid development upon the development of the host. The above descriptions are made from paratypes. The insect differs only slightly from pacificus, but has not gone the way of the usual synonomy. The gall is very much like that of pacificus on Q. Douglasii. It is possible that the aments of garryana will show galls of variety washingtonensis similar to the ament galls of pacificus on Q. lobata. The alternate generation of this insect may be either a similar leaf swelling, a woody stem swelling, or a cell in an acorn cup, and I have collected the latter gall at Ashland, Oregon.
