p. 116. 
FEMALE. — Mouthparts light piceous, antennae brown, the second 
and third segments straw yellow; abdomen hardly longer than wide, 
more or less produced dorsally; legs dull straw color at the joints and 
on the tarsi; areolet averaging a little larger than in tectus; radial 
cell rather narrow, length 0.8-1.5 mm. 
MALE. — As described for the species. 
GALL. — As described for the species; swelling on petioles, mid- 
veins, or ament stems, or anther capsules on Quercus stellata (figs. 
24, 25). 
RANGE. — Connecticut: Waterbury (?), West Rock (Bassett). New 
York (Beutenmuller). New Jersey: Lakehurst (Beutenmuller). Vir- 
ginia: Rosslyn. Probably confined to a northeastern area of the United 
States. 
TYPES. — Neuroterus exiguus: Females, males, and galls. Holotype 
female at the Philadelphia Academy; paratype females, males, and galls 
at the Philadelphia Academy and in the Kinsey collection; paratype 
females and males at The American Museum of Natural History, the 
Museum of Comparative Zoology, and in the Beutenmuller collection (?). 
From West Rock, Connecticut; Q. stellata; Bassett collector. 
Neuroterus gillettei: Females and males. Holotype female at the 
Philadelphia Academy; paratype females and males at the Philadelphia 
Academy and in the Kinsey collection. Probably from near Waterbury, 
Connecticut; on Q. stellata; Bassett collector. 
Bassett found his galls in May, the insects emerging by 
the end of the month. My material from Rosslyn, Virginia, 
was about ready to emerge on May 16, 1920. 
Felt’s reference to N. floccosus on ament flowers is ex- 
plained, by Dr. Felt himself, as a clerical confusion of exiguus 
with exiguissimus and the reduction of exiguissimus to a 
synonym of floccosus (following Beutenmuller) ; the reference 
applies to exiguus. 
Gillettei is certainly a complete synonym of exiguus. I 
have examined good series of paratypes of both names, com- 
paring them with types of all the related things, and cannot 
find any differences at all. The hosts of the two are the same.
