Kinsey: The Genus Neuroterus 
47 
Neuroterus niger variety pattersoni, new variety 
bisexual form pattersoni, new form 
FEMALE. — Color generally light piceous; the legs and antennae 
in no part darker than a light brown; the antennae very light yellow 
basally; areolet a little less than moderate sized; length 0. 6-1.0 mm., 
decidedly smaller than nig ripe s. 
MALE. — As described for the species. 
GALL. — Circular, not elongate, very slightly smaller than nigHpes, 
with more well-defined boundaries and without a trace of a central point 
on the upper surface. On Quercus stellata (fig. 43). 
RANGE. — Texas: Austin (Patterson coll.). 
TYPES. — 46 females, 69 males, and 8 pins of galls. Holotype 
female, paratype females, males, and galls at The American Museum of 
Natural History; paratype females, males, and galls at the U.S. Na- 
tional Museurn, the Museum of Comparative Zoology, the Philadelphia 
Academy, Stanford University, the California Academy, and in the 
Kinsey collection. Labelled Austin, Texas; March 10, 1921 (galls), and 
May 7, 1921 (insects) ; Q. stellata; Patterson collection number 93. 
Dr. Patterson, for whom this variety is named, collected 
and bred the type material. He states that in 1921 the gall 
first appeared March 10, the adults beginning to emerge on 
May 7. Dr. Patterson sent me records (a year ago) of breed- 
ing 453 females and 450 males, making the important observa- 
tion that a single leaf of galls usually yields only a single sex 
of the wasp. The detailed record of these observa- 
tions I should leave for Dr. Patterson to publish. It would 
appear that the agamic females are of two sorts, either 
female- or male-egg-producing. What is evidently the agamic 
form of pattersoni is described in the following paragraph. 
Neuroterus niger variety pattersoni 
agamic form hiemalis, new form 
FEMALE. — Does not differ from the bisexual female unless in 
average size and the shape of the abdomen. 
GALL. — Probably quite similar to that of the bisexual generation. 
On Quercus breviloba. 
RANGE. — Texas: Austin (Patterson coll.). 
TYPES. — 3 females, no galls. Holotype female at the Amer- 
ican Museum of Natural History; paratype females with the author. 
Labelled Austin, Texas; March 5, 1922; Q. breviloba; Patterson col- 
lection number 10 in small part. 
This material, altho on a different host than the types of 
pattersoni, does not appear to differ in any respect from the
