Kinsey: The Genus Neuroterus 
45 
Neurotus niger Felt, 1918 (in part), N.Y. State Mus. Bull., 200, p. 82. 
FEMALE. — Apparently (from the original description) is largely 
black in color, with the areolet rather large, the length 1.0 mm. 
GALL. — Rather rounded, somewhat elongate, with well-defined 
boundaries, without a central point on the upper surface. On Quercus 
macrocarpa. 
RANGE. — Iowa: Ames (Gillette). Illinois: Algonquin (Nason). 
Michigan: Lansing (Gillette). Possibly confined to a smaller area about 
Ames, Iowa. 
TYPES. — Females and galls supposed to be in the collections of 
C. P. Gillette and of the Agricultural College at Ames, Iowa. From 
Ames, Iowa; Q. macrocarpa; Gillette collector. 
I cannot locate the types of this variety. There are insects 
and galls in the Thompson collection, from Massachusetts 
on Q. macrocarpa, which fit the original description, but these 
may prove a distinct variety when we can make comparisons 
with types. Gillette stated that the galls of this agamic gen- 
eration appear late in August ; he collected his galls on October 
20, 1887 ; adults emerged on May 10, 1888. The Thompson 
material also over-wintered in the galls, emerging about the 
middle of May. Beutenmuller’s further data appear to be 
derived in part from variety perminimus which he considered 
a synonym of niger. 
Neuroterus uiger variety nigripes, new variety 
agamic form 
FEMALE. — Color generally dark piceous black to black; almost 
black on parts of the legs and antennse, the latter hardly lighter basally ; 
areolet of moderate size; length 0. 8-1-2 mm., decidedly larger than 
pattersoni. 
GALL. — About circular, slightly elongate, very slightly larger than 
pattersoni, with less well-defined boundaries and with a distinct central 
point on the upper surface. On Quercus stellata and Q. breviloha 
(fig. 34, 42). 
RANGE. — Texas: Austin, Leander. 
TYPES. — 12 females, many galls. Holotype female, para type 
female, and galls at The American Museum of Natural History; para- 
type females and galls in the U.S. National Museum, the Philadelphia 
Academy, and the Kinsey collection; paratype galls in the Museum of 
Comparative Zoology. Labelled Austin, Texas; December 4, 1919; Q. 
stellata; Kinsey collector. 
Larvae were in the galls I collected on December 4, 1919. 
Dr. Patterson has made detailed observations on this species, 
finding that the young galls were evident on July 28, 1921,
