FEMALE. — Eyes distinctly large, protruding slightly beyond the 
cheeks; cheeks very narrow; antennas brown, brownish yellow basally; 
thorax slightly wider than the head, the parapsidal grooves rather clearly 
cut posteriorly; furrow at base of the scutellum rather broad and 
smooth; legs bright golden yellow, only the coxae brownish; areolet quite 
large; length 1.7-2. 5 mm., averaging large. 
MALE. — As described for the species; areolet very large, more 
elongate than in ocularis. 
GALL. — A bud gall, as described for the species. On Quercus alba. 
RANGE. — Massachusetts: Springfield (Stebbins); Boston (Clarke). 
Connecticut: Waterbury (Bassett). New York (Beutenmuller). New 
Jersey: Lakehurst (in coll. Amer. Mus. Nat. Hist.); Ft. Lee (Beuten- 
muller in coll. Mus. Comp. Zook). Probably confined to a northeastern 
area of the United States. 
TYPES. — Females and galls. Holotype female at the Philadelphia 
Academy; paratype females and galls at the Philadelphia Academy, 
The American Museum of Natural History, the Museum of Comparative 
Zoology, and Stanford University, and in the Beutenmuller collection (?) 
and the Kinsey collection. From Waterbury, Connecticut; Q. alba; 
Bassett collector. 
Bassett recorded these galls as partially developed in the 
fall, maturing rapidly in the spring, and the insect emerging 
by the time the oak leaves are expanded, usually in April or 
early May. The Millett Thompson material from Massachu- 
setts (probably from near 'Worcester) is, as far as I can 
perceive, in agreement with the Bassett types, but possibly 
the Springfield, Massachusetts, record applies to another vari- 
ety. Vesicidn is probably confined to Quercus alba, and the
