FEMALE. — Antennse basally golden yellow, legs bright yellow, in 
part yellowish brown; areolet quite small; length 1.5-1. 7 mm. 
MALE. — As described for the species; pleurae wholly brownish 
piceous. 
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. 
TYPES. — Named Neuroterus politus Bassett. Holotype male, para- 
type males (and females) and galls at the Philadelphia Academy. From 
Southern Utah; Q. Gambelii { = Q. undulata only of older authors); 
Siler collector. 
This insect most closely resembles variety congregatns 
of more eastern Colorado, but the more golden yellow of the 
antennse and legs, and the much smaller areolet will distin- 
guish quercicola. The male only was described by Bassett, 
but he stated that he had a female also, and I have examined 
both female and male type material. Bassett’s name politus 
was preoccupied by Neuroterus politus Hartig, 1840, and was 
changed to quercicola by Dalla Torre.

Neuroterus washingtonensis Beutenmuller, 1913, Can. Ent., XLV, p. 280, 
pi. IX. Felt, 1918, N.Y. Mus. Bull., 200, p. 81. 
FEMALE. — Antenna basally golden yellow; the legs golden yellow, 
in part dark brown; the areolet of moderate size, and the length 
1. 5-2.0 mm. 
MALE. — As described for the species; pleurae wholly bright, brown- 
ish yellow; the legs wholly golden yellow. 
GALL. — As described for the species; a rather large vein swelling 
involving and deforming more or less of the blade; of indefinite shape; 
green, succulent when fresh, drying brown and rather hard, without 
much shrivelling; up to 35. mm. in length and 15. mm. in diameter. On 
leaves of Quercus garryana. 
RANGE. — Washington: Friday Harbor (Puget Sound) (Weld 
coll.). Oregon: Ashland, Canby. Probably thruout northern Califor- 
nia, Oregon, Washington, and northward, wherever Q. garryana occurs. 
TYPES. — Hundreds of adults and galls. Holotype in the Beuten- 
muller collection; paratypes at the U.S. National Museum, the Museum
