Kinsey: The Genus Neuroterus 
75 
tary, the U.S. National Museum, the Museum of Comparative Zoology, 
and the Philadelphia Academy, and in the Kinsey collection. Labelled 
Massachusetts; spring; Q. bicolor; Thompson collection number 103. 
This insect has been passing as true floccosus, altho the 
type locality of the latter is in a different faunal area. The 
hosts of the two are the same, but their ranges are distinct. 
Pernotus is generally more rufo-piceous than floccosus, and 
decidedly smaller, with a smaller areolet. The Bassett ‘Types” 
of floccosus contain a considerable amount of pernotus, as 
explained under floccosus. The type material of pernotus was 
bred by Millett Thompson. Insects and galls from Q. bicolor 
in New Jersey do not appear to differ from the Thompson 
material, but varieties in this species are to be distinguished 
by such poor characters that one should not conclude that 
the whole of Massachusetts and New Jersey lie in the same 
faunal area. 
Neuroterus verrucarum variety pulvinus, new variety 
FEMALE. — Color generally black; antennae brown, lighter only on 
the second segment; the middles of the coxae, femora, and tibiae brownish 
black, the legs otherwise rather light yellow; wing veins quite fine; 
areolet of moderate size or a little smaller; the first abscissa not as 
angulate as in inflciens; length 1.0-1. 2 mm. Differs from opacus only in 
averages, not sufficient to determine every individual; slightly larger, 
the abdomen slightly more produced dorsally, the first abscissa slightly 
more angulate, the eyes slightly larger. 
GALL. — Quite different from the galls of other varieties; mono- 
thalamous, a flattened hemisphere, roughened, but with only a slight, 
microscopic pubescence; older galls dark brown; rather thick-walled; 
lying largely below the under surface of the leaf, the point not at all 
evident on the upper surface, but the gall attached broadly, solidly, and 
not easily separable. On Querciis stellata. 
RANGE. — Texas: Austin (Patterson coll.); Yoakum, Sinton. 
TYPES. — 440 females, many galls. Holotype female, paratype 
females, and galls at The American Museum of Natural History; para- 
type females and galls at the Museum of Comparative Zoology, the 
U. S. National Museum, the Philadelphia Academy, Stanford University, 
and the California Academy, and in the Kinsey collection. Labelled 
Yoakum, Texas; November 30, 1919; Q. stellata; Kinsey collector. Some 
adults of variety opacus may be in these types. 
In late November the type galls contained active adults; 
many galls showed exit holes, but whether of cynipids or 
parasites I could not determine. Dr. Patterson cut insects 
from his galls in January.
