Museum of Comparative Zoology, the Philadelphia Academy, the Cal- 
ifornia Academy, the Berlin Museum, and the British Museum. All of 
the females are broken. Labelled Fallbrook, California; February 26, 
1920; Q. Engelmannii; collector. 
Larvse were in these galls on February 24 and 26, 1920. 
Neuroterus iiiger variety grisese, new variety 
agamic form 
FEMALE. — Color generally piceous black; legs and antennae in 
part piceous black, the antennae light brown basally; areolet very small 
or closed; length probably a little less than 1.0 mm. 
GALL. — A little more elongate than circular, with very poorly de- 
fined boundaries and not much thickening of the blade, perceptible mostly 
because of a discoloration, less perceptible on the under surface. On 
Quercus grisea. 
RANGE. — Texas: Fort Davis. New Mexico: Hillsboro. Probably 
occurs in West Texas, New Mexico, and adjacent Mexico (and Ari- 
zona?) . 
TYPES. — 3 females, 30 pins of galls. Holotype female and 
paratype galls at The American Museum of Natural History; paratype 
females and galls in the Kinsey collection; paratype galls at the U.S. 
National Museum, the Museum of Comparative Zoology, and at the 
Philadelphia Academy. The insects are broken, but total complete parts. 
Labelled Fort Davis, Texas; December 16, 1919; Q. grisea; Kinsey col- 
lector. 
The insects probably did not emerge from the galls until 
early in the spring after collecting. The galls are indistinct 
and not at all noticeable; the insect is clearly different from 
other varieties; so it seems worth describing even tho the 
type material is not abundant.
