NEMISTRINIDtK. 



Species of moderate size, thinly or thickly pilose. Neuration 

 complicated; the basal cells elongate. Antennae small, short; third 

 joint simple, with a terminal, slender, jointed style. Ovipositor of 

 the female elongate, often slender. Tibia; without spurs ; empodia 

 developed pulvilliform, but, with the pulvilli, often minute. 



But four species of this small family are known from the United 

 States, and they will be readily recognized by the accompanying 

 cut of the wing of llhynchocephalus volaticus Will. The 

 habits of the larva- of this family are known in but one species.
