Kinsey: The Genus N euroterus 
79 
black, only a little larger than the thorax, almost as high as to higher 
than long, distinctly triangulate, the ventral spine almost lacking; legs 
largely yellow, tarsal claws very fine, simple (weakly toothed in contor- 
tus) ; wings clear, ciliate, very short or not ciliate on the anterior mar- 
gins; areolet placed symmetrically below the apex; radial cell of more 
moderate width, with the terminal portion of the subcosta rather long; 
the first abscissa bent only very near the subcosta; length 1. 2-2.2 mm. 
MALE. — Color similar to the female or more often largely yellow, 
the legs and antennae more yellow; eyes more or less enlarged, in some 
cases distinctly protruding beyond the cheeks; the third segment of the 
antenna as long to twice as long as in the female and more or less 
distinctly curved; thorax including the scutellum more narrow and 
elongate; abdomen very small, much smaller than in the female; areolet 
larger or smaller than in the female; length a little greater than in the 
female. 
GALL. — A simple, inseparable swelling of the affected part, usually 
several cells located together so the swelling is more or less continuous, 
polythalamous, but the cells separate in cupule or anther galls. Hyper- 
trophy never great, sometimes very little, irregular in outline (except in 
ament galls), succulent or woody as the normal tissue, covered with 
the normal tissue, solid, the larval cells with distinct but wholly in- 
separable linings. On older or younger stems, petioles, leaf veins, ament 
stems, anthers, or cupules; of white oaks of all groups. 
RANGE. — North America, from the Atlantic to the Pacific, probably 
wherever white oaks occur. 
TYPE . — Cynips q. majalis Bassett = Neuroterus (Dolichostrophus) 
irregularis variety majalis (Bassett). Implied by Ashmead, 1887, Trans. 
Amer. Ent. Soc., XIV, p. 129, and affirmed by Ashmead, 1903, Psyche, 
X, p. 151. 
This subgenus is known from 8 American species, batatus, 
contortus, decipiens, duhius, irregularis, minutus, quercicola, 
and rileyi, representing 25 varieties. These eight species may- 
present a total of about 240 distinct varieties. Other distinct 
species may be found among root swellings, or very slight 
stem or leaf vein swellings; some species may not produce 
galls at all, as is the case sometimes with varians. Direct 
alternate generations are known for 5 of the varieties, of 
three species, and can safely be predicted for all the varieties 
of batatus, contortus, quercicola, and rileyi. Four species 
occur only in eastern North America, one is known only from 
Texas, one is restricted to western North America, one is 
restricted to the Pacific Coast, and one is transcontinental. 
I do not recognize Dolichostrophus in the Old World. 
The galls of Dolichostrophus are all very simple, but little 
better than larval cells in plant tissue, but there is some
