This genus represents a unique form intermediate in develop- 
ment between Lestremia and the highly reduced antennal struc- 
tures of Microcerata and Tritozyga. It is more closely allied to 
the former though easily separated therefrom by the normal second 
antennal segment, the digitate antennal appendages and _ the 
stoutly pectinate claws. The type species is N. tridens n. sp.

insect developed from the very slight amount of decaying organic 
matter brought in with the sand. We are unwilling to believe that 
it is the parent insect of the semitransparent larvae producing. in 
midsummer the numerous ocellate galls on soft maple leaves. 
Paridris nigricornis Brues was reared from this jar 
and may be a parasite of C. ocellaris OS,
