tive evidence, and we need further proof that this summer 
generation is agamic, but it does look as if here might be 
a case of a species in which no bisexual generation ever does 
occur. I have further examined fine lots of saltatorius mate- 
rial collected at frequent intervals thru the late fall and winter 
of two years by Mr. Leach, and these galls do not mature 
until January or February, the insects emerging late in the 
winter or early in the spring. This is very evidently the 
winter generation, agamic as we have observed and as would 
be expected in Neuroterus. I have not described these two 
generations as different forms because they are apparently 
identical (even as to sexuality) except for their seasonal 
occurrence. 
Neuroterus saltatorius variety texanus, new variety 
FEMALE. — Antennae light brown, golden yellow basally; legs dull 
yellow at the joints and on the tarsi; length 0.6-0. 9 mm. 
GALL. — About globose, hardly any longer than high or wide, en- 
tirely irregularly roughened, without a trace of a distinct tip apically; 
gall small; on Quercus virginiana (fig. 28). 
RANGE. — Texas: Austin (Patterson coll.); Yoakum, Skidmore, 
Hondo, (Leander?). 
TYPES. — 13 females, 5 pins of galls. Holotype female, para- 
type female, and gall at The American Museum of Natural History; 
paratype females and galls at the U.S. National Museum and in the 
Kinsey collection ; paratype females at the Museum of Comparative 
Zoology and the Philadelphia Academy. Labelled Austin, Texas; March 
8, 1922; Q. virginiana; Patterson collection No. 12. 
I have galls of this variety from several localities, but 
Dr. Patterson has succeeded in breeding the wasp. He states 
that the galls appear late in the fall, the insects emerging 
by March 8 in 1922. My Leander record may apply to a 
distinct variety confined to a small area in Central Texas.
