TYPES. — I have not been able to locate the Kieffer material. From 
Ucles, Spain; Q. Ilex; Pantel collector. 
The present remarks on this insect are based on the original de- 
scription. 
Nothing seems to be known of this insect beyond the data 
accompanying Kieffer’s original description of ilicis quoted 
in this paper. The insect characters mentioned in the de- 
scription would not distinguish any variety of folii, and even 
the tuberculate surface of the gall would not of itself warrant 
the recognition of a distinct variety. Nevertheless I cannot 
accept Kieffer’s (1903) later conclusion that ilicis is a syno- 
nym of yubescentis, for the hosts of the two, Q. Ilex and Q. 
yubescens, are as distinct as Q. alba and Q. virginiana in the 
eastern United States. From our American experience we 
should expect distinct, host-limited varieties from each of 
these oaks, and it seems unwise to bury this insect in 
synonomy until we have had an opportunity to compare good 
series of Q. Ilex insects from Central Spain with series of 
Q. yubescens insects from Austria. 
In combining ilicis with the generic term Cyniys, we find 
the name pre-occupied by Fabricius’ ilicis (1798), and have 
consequently substituted the new name ilicicola.

FEMALE. — Entire body including the legs and antennae piceous to 
jet black, rarely with a little rufo-piceous; the mesonotum smooth, shin- 
ing, and quite naked except around the rim and along the parapsidal 
grooves, with a fine reticulation in places especially anteriorly between 
the anterior parallel lines; anterior parallel and lateral lines obscure; 
scutellum as rugose anteriorly as posteriorly; the foveal groove at least 
in part rugose; the mesopleuron with a smooth and naked spot or band 
above the center; the tip of the second abscissa of the radius not at all 
enlarged; length 2.1 to 2.7 mm., conspicuously smaller than folii or 
yubescentis. Figure 96. 
GALL. — Apparently similar to the galls of the variety folii, the 
dried galls soft and spongy, probably nearer 10. mm. in diameter. On 
the leaves of the Q. Robur group of oaks. 
RANGE. — Denmark: Bromme (Hoffmeyer; types). Korsor (Hoff- 
meyer in Kinsey coll.). 
Probably restricted to a more northern area in Europe near the 
northern limits of oaks. Figure 15.
