maturing- about the first of DecemiDer ; he secured adults about 
the first of March, 1921. Dr. Patterson has bred galls from 
both Q. stellata and Q. hreviloha, and I cannot see any dif- 
ferences between the two lots of material. Another variety, 
patter soni, also occurs at Austin on both of these oaks, but 
the insects and galls are always distinguishable. Evidently 
two faunal areas, meeting at Austin, have effected an isolation 
which is not accomplished by the two hosts.

Neuroterus papillatus Beutenmuller, 1910, Bull. Amer. Mus. Nat. Hist., 
XXVIII, pi. X, fig. 2. 
FEMALE. — Color generally piceous rather than black; the an- 
tennae brown, pale yellowish brown basally; the legs pale yellowish; the 
areolet very small; the length 0.7 mm. 
MALE. — As described for the species. 
GALL. — Elongate, quite slender, small, with fairly well-defined 
boundaries, without a trace of a central point on either side. On 
Quercus bicolor (fig. 35). 
RANGE. — Rhode Island: Providence (in Thompson coll.). New 
York: Bronx Park, New York City (Beutenmuller) ; West Nyack (Felt 
in N.Y. State Mus.). Probably confined to a more northeastern area 
of the United States, on Q. bicolor. 
TYPES. — Females, males, and galls in the Beutenmuller collec- 
tion? Adults and galls, probably types, at The American Museum of 
Natural History. Adults at the Museum of Comparative Zoology. 
From Bronx Park, New York; Q. bicolor; Beutenmuller collector. 
I have not been able to examine the types of this variety, 
and have made my descriptions from Q. bicolor material from 
West Nyack, New York, sent me by Dr. Felt. I have galls 
from the Thompson collection, from the typical host, from 
Providence. These agree with Beutenmuller’s figure in being 
narrowly elongate, and quite distinct from the more circular 
galls of niger or per minimus. The cynipid fauna of Q. bicolor 
is usually unique, and it is not likely that this variety occurs 
on any other host.
