Kinsey: The Genus Neuroterus 
95 
published descriptions give 14 segments for female antennae, 
all but these two records are errors; only irregularly do in- 
dividuals of some of the other species of this subgenus show 
14 segments, while duhius has that number regularly. 
Two varieties previously described, and one new variety, 
all known from only a limited amount of material, represent 
about all we yet know of duhius, and this information is not 
sufficient to warrant too much prediction concerning the oc- 
currence of other varieties; but the wide distribution of the 
known varieties suggests that many faunal areas and many 
hosts are affected, with consequently several score of vari- 
eties in existence. In addition to the varieties described here, 
I have an insect from Q. prinoides in eastern Massachusetts. 
All of the known varieties are bisexual, in spring galls, 
the insects emerging not very late in the spring. The galls 
of only a single form are known, the other insects having 
curiously turned up in collections of galls of other Cynipidse. 
Probably the galls of all varieties are so small and simple 
as to be overlooked in collecting.

FEMALE. — Mouthparts piceous yellow, only the first three anten- 
nal segments yellow; mesonotum largely smooth, with little or no traces 
of parapsidal grooves; scutellum only in part roughened, the basal fur- 
row smooth; legs light yellow, in part suffused with light brownish; 
areolet very small, almost closed; length 1.2-1. 5 mm. 
MALE. — As described for the species; with the first three antennal 
segments yellow; with only fine indications or no indications of parap- 
sidal grooves. 
GALL. — As described for the species; on the edge of the leaf, or on 
aments of Quercus alba (figs. 53, 54). 
EANGE. — Massachusetts: Magnolia (Clarke coll.). New Jersey: 
Broadway. Probably confined to a more northeastern portion of the 
United States. 
TYPES. — Females, males, and galls in the Beutenmuller collection. 
From Magnolia, Massachusetts; Q. alba; Cora H. Clarke collector. 
Beutenmuller’s Massachusetts material emerged in late 
May and early June; my New Jersey material emerged soon 
after collecting on May 19, 1920. The type galls occurred on 
leaves ; my material was on the aments ; I have not been able
