This genus is closely allied in general appearance and habits to 
Lasioptera, and is separated therefrom only by the fifth vein fork- 
ing at the extreme base of the wing or by the sixth being entirely 
independent of the preceding | pl. 34, fig. 8]. This character, while 
not always determined with ease, affords a very good basis for 
making a division, even though this latter may not be closely cor- 
related with variations in habit. The female antennae may be com-

As in the genus Lasioptera, there is frequently a variation of four 
or five segments between the sexes and apparently following no law. 
The species of this gents, as in the case of Lasioptera, breed 
mostly in subcortical stem galls on herbaceous and woody plants, 
most of the forms producing distinct enlargements, though the 
presence of N. hibisci is indicated only by a somewhat gen- 
eral enlargement of the stem. N. squamosa has been bred 
from grass, presumably a stem gall, while N. vitinea makes 
a characteristic conical gall on the grape petiole.
