occurring- west of the Appalachians until we found it in 
western Kentucky and southern Missouri where I have re- 
covered fine series of the insects. From west of Dexter, in 
the southeastern corner of Missouri, collections made on a 
small clump of Q. stellata scrub, located very near the fault 
that separates the river lowlands from the highlands, gave 
me forty insects, two of which represent the Ozark variety 
unica and 38 of which are typical Carolina. From Springfield, 
from near the southwestern corner of Missouri, I have 25 in- 
sects, 9 of which are unica and 16 of which are Carolina. The 
insect is so unique as to leave no possibility of mis-determina- 
tion, and the galls of unica and Carolina are similarly distinct, 
so there can be no doubt of the occurrence of the Atlantic 
Coastal Plain variety all the way across the state of Missouri. 
Except for the type collections, all of the insect material I 
have examined has come from Q. stellata (the post oak), to 
which the variety seems largely confined. The type speci- 
mens recorded as from Q. alba seem no different from this 
Q. stellata material unless the insects average a little smaller 
in size. Beutenmuller’s record (in Smith, 1910, Ins. N.J. : 
599) of similar galls on Q. prinoides (the chinquapin oak) , and 
specimens I have from this same oak from Roselle, N. J. (C. J. 
Long, Jr., coll.) will probably prove to belong to another va- 
riety. Weld’s record of Carolina from Q. stellata at Ironton 
in the Missouri Ozarks should be re-examined in connection 
with the numerous varieties now described. 
Beutenmuller records the galls as occurring in August, Sep- 
tember, and October. I have found mature galls still attached 
to the leaves in the middle of October in southern New Jersey 
and Virginia, and at the end of October in the mountains of 
the western part of North Carolina and eastern Tennessee. 
The galls I collected at Dexter, Missouri, late in October 
(1926), were mature and dropping from the trees, but the 
insects did not emerge until the following March. I have bred 
other material early in January. Weld collected galls in Octo- 
ber from which he reared adults in the following June, but 
this seems late emergence for a species in which the other 
known varieties emerge in the late winter or early spring. 
One of my insects from Marshall, North Carolina, seems 
identical with typical Carolina from the same locality except 
that it is almost entirely piceous in color.
