Kinsey: The Genus Neuroterus

not show a larval cell grossly distinguishable from the rest 
of the tissue. The insect is very closely related to the other 
American species of this subgenus, and most closely to um- 
hilicatus, but the dorsally produced abdomen is unique to sal- 
tatorius and may again indicate some specialization. 
Galls, undoubtedly varieties of this species, have been 
recorded from a wide range of localities and hosts, including, 
in addition to the described varieties, material from Quercus 
alba, Q. stellata, Q. macrocarpa, Q. dumosa, and Q. garryana, 
from Connecticut, New York, New Jersey, Ohio, Indiana, 
Missouri, Michigan, and Colorado. I have galls from localities 
in western Texas on Q. grisea, northern California on Q. 
chrysolepis, New Mexico on Q. grisea and Q. Gambelii, North 
Carolina on Q. stellata, and Indiana on Q, alba. The species 
then ranges across the continent, on white oaks including 
the evergreen species, but as far as known excluding the 
chestnut oaks. Almost seventy varieties of this species should 
occur in the United States. The following are the published 
references to undescribed varieties.

Neuroterus saltatorius variety australis, new variety 
FEMALE. — Antennae golden yellow basally; legs largely yellow 
including the coxae, the front legs especially yellow, legs brown on the 
middle and hind femora and tibiae; length 1.0-1. 2 mm. 
GALL. — Rather spherical, slightly elongate, without an apical tip; 
entirely but very finely pubescent; rather small; on Quercus stellata. 
RANGE. — Texas: Austin (Patterson collector). 
TYPES. — 11 females, 12 pins of galls. Holotype female, para- 
type female, and galls in The American Museum of Natural History; 
paratype females and galls in the U.S. National Museum, the Museum 
of Comparative Zoology, the Philadelphia Academy, and the Kinsey col- 
lection. Labelled Austin, Texas; galls 1921, insects March 6 to 13, 1923; 
Q. stellata; Patterson collection 111. 
The insects emerged from March 6 to 13, 1923. This 
gall has been known for some time, but the insect is not easily 
reared. Dr. Patterson secured only 11 females from many
