Kedescribed from many specimens of both sexes as follows: Oarbon- 
dale, Illinois, .lime 2i-20, 1907, ,1. I). Hood, both se.xes reared abundantly 
from pup;e taken in phylloxera galls on hickory leaves; Hillery. 111., 
.lime 10, 1908, (4. .\. Hart, both sexes common on hickory leaves; Alt. 
(’armel, TIL, Alay, l.SSt, in phylloxera galls on hickory leaves (.\cc. No. 
2:’)dS, III. State Lab. .Nat. Hist.); Pulaski. III.,.May 21, 1907, ('. .\. Hart. 
I male swept from gra.ss and weeds; Plummer’s Island, Alaryland, .Tune 
S and 29, 1918, .1. 1). H., on hickoi-y leaves, and reared from juipu' in 
phylloxera galls on hickory leaves. 
The large size, truncate vertex, long, i)ointed bristles, and the long 
tube are the |)rincipal diagnostic characters. 
I have ilesignated the above specimens as the “ neoty|K's ” of thespecies, 
Fitch’s oris,dnal types having been lost.
