Neuroterus cockerelli
Hosts: Quercus sp
GALL. — On the leaves of a species of oak. Hemispherical or subhemispherical, pale brown, minutely crackled, hard and flattened at the base. Width, 4 mm.; height, 2.50 mm. (fig. 36).
HABITAT.— Manitou, Colorado (T. D. A. Cockerell).
I have been unable to secure any certain information as to this name. The type may be in the Beutenmuller collection, and is unavailable to me. This is the only published name in the American groups of the genus which I have not been able to interpret. From the original description one might place the insect in Diplobius, and it may be a variety of saltatorius. Professor Cockerell has sent me what appeared to be galls similar to the material he had sent Beutenmuller; these galls were on Q. Gambelii; they fitted the original description and figure, but they contained insects related to Dryophanta eburnea Bassett. The original description of the insect does apply to a Neuroterus, but the possibility of the insect having been wrongly connected with the gall must be considered when some student of Cynipidae has an opportunity to study the Beutenmuller type. In the statistics given thruout this paper, I have treated cockerelli as some variety, instead of a distinct species.
