Characters. — Cornicles absent. Stem-mother with five-segmented antennae; alate 
form with the media simple, the cubitus and anal joined near their bases. Hind wings 
with only the media present, antennae of six segments, armed with large subcircular 
or elongate sensoria. Forms living in true galls. 
Type (mono typical), Tetraneura lentici Pass.

Walsh erected his genus for rliois Fitch, a species forming galls on 
sumach and in his discussion mentioned the Chinese gall, wonder- 
ing if it could be congeneric. The writer has recently published an 
account of the Chinese gall 1 and therein placed Schlechtendalia Licht. 
as a synonym of Melaphis. Del Guercio' s genus w^as erected with 
his lazarewi as type and placed as a thelaxine. Although the writer 
has never obtained specimens of this species he is of the opinion 
that it can not possibly be one of these insects and that it evidently* 
belongs in the Melaphini where the shape of the stigma would imme- 
diately place it as a Melaphis. 
Characters. — Cornicles absent. Apterous form with five-segmented antennae. 
Alate form with either five or six segmented antennae which are armed with some- 
what linear or oval sensoria. Fore wings with the media simple, although sometimes 
slightly forked, distal extremity of the stigma rather long drawn out; hind wings with 
both media and cubitus present; abdomen with distinct wax plates. Forms living 
in galls from which the alate forms escape in late summer or fall. 
Type (monotypical), Btjrsocryjpta rhois Fitch.

Matsumura erected his genus Nurudea for his Nurudea ibofuslii, a 
species somewhat similar to a species of Melaphis. This species differs 
quite markedly, however, in the form of the stigma. At the same 
time he erected the genus Nurudeopsis with N. sJiiraii as type. This 
species differs little from ibofuslii excepting in the proportions of the 
segments, and in the fact that the cubitus and first anal are some- 
what closer togetner at the base. The writer is of the opinion that 
these characters are not sufficient on which to form another genus. 
In the same work also he erected the genus Fushia with Fushia rosea 
Mats, as type. This species differs somewhat from the t} r pe of Nuru- 
dea but the writer believes that there are not differences sufficient 
to cause this to be considered as a separate genus. The antennae
