p. 320. 
FEMALE. — Mouthparts light rufous, the first four antennal seg- 
ments yellow; mesonotum in large part roughened, with rather distinct, 
roughened traces of parapsidal grooves for the posterior half of the 
mesonotum; scutellum closely, entirely roughened, the basal furrow 
somewhat roughened; legs wholly golden yellow; areolet very small; 
length 1.5 mm. 
MALE. — As described for the species; with only three antennal 
segments yellow; with fine and more or less broken parapsidal grooves, 
but these distinct to the pronotum. 
GALL. — Not known. Probably similar to those described for the 
species. Apparently on Q. stellata. 
EANGE. — Connecticut: Waterbury. Probably confined to a more 
northeastern portion of the United States. 
TYPES. — 3 females, 5 males, no galls. Holotype female, paratype 
females, and males at the Philadelphia Academy. From Waterbury, 
Connecticut; Q. stellata; Bassett collector. 
The above descriptions are made from a paratype female 
and a paratype male. This insect was obtained by Bassett 
from a box of galls of Andricus prutnosus, and he did not 
find galls which might have been made by the Neuroterus. 
Pruinosus comes from Quercus stellata, and probably dubius 
has the same host.

FEMALE. — Head largely black, the face piceous; antennae brown, 
yellow to straw white basally, with 13 segments, the third twice as 
long as the fourth; thorax black, only a little longer than high or wide; 
mesonotum and scutellum smooth to faintly coriaceous, naked of hairs; 
mesopleurae finely roughened; abdomen in part black, in part piecous, 
higher than long, extending ventrally almost or fully as far as dorsally ; 
legs wholly straw yellow or whitish; areolet rather large, variable in 
size; a faint brownish cloud at the midpoint of the basalis; radial cell 
very largely closed; length 1. 5-2.0 mm. (figs. 4, 14). 
MALE. — Head black, the lower part of the face lighter than in the 
female, thorax dorsally and abdomen more or less brown, the thorax 
laterally and the petiole yellow to straw white; eyes very considerably 
enlarged ; antennae generally lighter, with the third segment much 
lengthened, distinctly curved, half again as long as the first plus the 
second; length a quarter greater than in the female (fig. 5). 
GALL. — A thick, leaf blade swelling, involving both surfaces of the 
leaf, with the larval cells mostly deeply imbedded. Polythalamous.
