contradiction in investigations such as life histories, cytology, 
host relations, distributions, etc. The lack of adequate tax- 
onomic work has undoubtedly been responsible for many mis- 
takes thruout the fields of biology. 
Both opacus and pulvinus occur at Yoakum and Austin, 
Texas, on the same host and even on the same leaves. It is 
hard to see what isolation factors are favoring the segregation 
of two distinct things. Possibly the two localities are on 
the boundary between two faunal areas. This view is favored 
by the fact that I secured opacus in abundance but failed to 
find pulvinus at the many localities where I collected in the 
areas eastward from Austin and Yoakum. 
Neuroterus verrucarum variety restrictus, new variety 
FEMALE, — Color generally black or piceous black; antennae brown, 
lighter brown basally but yellowish brown only on the second segment; 
middles of coxae, femora, and tibiae dark brown, the remainder of the 
legs rather light yellow; wing veins fine, the areolet of moderate size; 
length 1.2-1.5 mm. 
GALL. — Rather large, with a distinct papilla on the upper surface; 
on Quercus Chapmanii and Q. Margaretta (and Q. geminata?) . 
RANGE. — Florida: Bowling Green, Milton, New Smyrna. Georgia: 
Jesup. Probably confined to the very southeastern portion of the United 
States. 
TYPES. — 6 females, many galls. Holotype female, paratype fe- 
male, and galls at The American Museum of Natural History; paratype 
females and galls at the U.S. National Museum and in the Kinsey 
collection; paratype galls at the Museum of Comparative Zoology and 
the Philadelphia Academy. Labelled Bowling Green, Florida; Novem- 
ber 13, 1919; Q. Chapmanii; Kinsey collector. 
This insect is best distinguished from minutissimus by 
the larger size, the darker legs, and the larger areolet. The 
galls, collected in November, probably did not give adults 
until the following spring. Insects from Jesup, Georgia, and 
from Milton, Florida, on Q. Margaretta, and from New 
Smyrna on Q. geminata, appear to me to be the same as the 
types of restrictus. It is not impossible that some of the 
other related oaks of northern Florida and adjacent Georgia 
may bear the same variety.
