Kinsey: Gall Wasp Genus Cynips 
308 
ung heller braunlich-gelb ; das bucklig abgerundete Schildchen neigt 
nach hinten liber, ist dicht und lang behaart, namentlich an der Spitze. 
Mit der Lupe erkennt man deutlich die Furchen der Parapsiden und 
die Griibchen an der Basis des Schildchens. Die lang vorgezogene Spitze 
des ersten Hinterleibssegmentes ist mit starkeren braunen Borsten 
besetzt. Die gelbbraunliche, wenngleich schwache Behaarung giebt dem 
Thiere trotz der dunkelbraunen Grundfarbe ein helleres Ansehen. Die 
Fliigel endlich sind ausserst charakteristisch : seine Areola ist nicht 
vollig geschlossen, die aussere Cubitalzelle zeigt nahe dem Fliigelrande 
eine zickzackfbrmige Zeichnung von derselben dunkelbraunen Farbe wie 
die Adern des Fliigels. Auch ist im Gegensatze zu No. 1 und 2 die 
innere Cubitalzelle in der hinteren Innenecke often. 
Translation. — Diplolepis quercus-rubrae new species. The gall is 
nearly spherical with a diameter of 20.0 mm. At the point of attach- 
ment (to the leaf?) there is a small depression resembling a navel and 
the entire base of the gall is rather flattened. The wall of the gall 
consists of a thin, opaque shell, the upper half of which is yellowish 
and marked with irregularly distributed, reddish brown splotches or 
spots, while the lower half is beautifully whitish and unmarked. In the 
hollow interior there is a small, irregularly shaped larval cell, which is 
solidly held in place in the center of the gall by radiating and very 
delicate, yellowish white fibers which extend from numerous, irregularly 
developed points to the inner surface of the outer wall of the gall. In 
the Berlin Museum there are exhibited two nearly identical specimens 
of this pretty gall showing the emergence holes of the insect, these 
galls consequently fully developed but differing somewhat in their size, 
for the larger has a height of 20.0 mm. and a horizontal diameter of 
23.0 mm. The label of this specimen reads “from Van Zandt, from 
Quercus rubra Linnaeus.” Further data are lacking, and only the gall 
and its producer are there, so it is impossible to state precisely where 
the gall is attached to the tree; but because of the similarity of the 
gall to our Diplolepis longiventris it seems not unwarranted to conclude 
that this is also a leaf gall. 
In the examples available, the insect shows principally Dryophanta 
characters. It is 4.0 mm. long, with a wing expanse of 11.0 mm. The 
antennae are 14-segmented and are not enlarged terminally ; the body, 
antennae, and legs are brown, the body [thorax] is densely set with 
short hairs, the hairs bright brownish yellow; the hump-backed, rounded 
scutellum projects posteriorly and it is densely hairy with long hairs, 
particularly at the tip. With a lens one may readily discover the parap- 
sidal grooves and the foveae at the base of the scutellum. The elongated 
tip [hypopygial spine?] of the posterior segment of the abdomen is set 
with rather stiff brown hairs. The golden brown hairs, even tho not 
abundant, give the animal a brilliant aspect in spite of its dark brown 
ground color. Finally, the wings are very characteristic: the areolet 
is not small, the third cubital cell has, near the anterior margin of the 
wing, a zigzag marking of the same dark brown color as the veins of 
the wing. On the other hand the first cubital and discoidal cells are 
open at base [ i.e . the cubitus does not extend to the basalis].
