N euroteo'-us cockerelli Beutenmuller, 1910, Bull, Amer. Mus. Nat. Hist., 
XXVIII, p. 125, pi. XI, %. 10. Felt, 1918, N.Y. State Mus. Bull., 
200, pp. 82, 104, fig. 107 (10). 
The original description is as follows: 
FEMALE. — Head, thorax and scutellum black, shining and micro- 
scopically crackled and wrinkled, more distinctly so at the sides of the 
head and thorax. Antennse 13-jointed, slender, first, second and third 
joints pale yellowish, remaining joints dusky brown. Thorax without 
grooves. Scutellum with a broad transverse groove at the base. Ab- 
domen shining, smooth, pitchy brown black or wholly black. Legs: 
Femora and tibiae dark brown, joints pale, coxae and tarsi pale yellow- 
ish. Claws black. Wings hyaline, veins distinct, brown. Areolet large. 
Cubitus reaching the first cross-vein. Length, 1.25 to 1.75 mm. 
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 sal- 
tatorius. 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 de- 
scription 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 Cynipidse has an oppor- 
tunity to study the Beutenmuller type. In the statistics given 
thruout this paper, I have treated cockerelli as some variety, 
instead of a distinct species.
