Neptunimyia Felt 

 1912 Felt, E. P. N. Y. Ent. Soc. Jour., 20:237 



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. t r i d e n s n. sp.

This most interesting female was reared April 17, 191 1, from 

 a jar containing maple leaves infested last year with the larva 

 of Cecidomyia ocellaris O.S. It is possible that the

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 O.S.
