Gen. NERUA, n. g.

_Foem. Corpus_ longiusculum, sublineare. _Caput_ transversum, thorace
non latius. _Antennae_ breves; articulus tertius rotundus; arista
apicalis, longa, tenuis, setiformis. _Thorax_ productus. _Scutellum_
spinis quatuor longiusculis. _Abdomen_ depressum, sublineare, thorace
vix latius, non longius. _Pedes_ graciles, non longi. _Alae_ angustae;
venae bene determinatae.

_Female._ Body rather long, nearly linear. Head transverse, not broader
than the thorax. Antennae short; third joint round; arista apical, long,
slender, setiform. Thorax long. Abdomen flat, thin, nearly linear,
hardly broader and not longer than the thorax. Legs slender, not long.

abdomen.
