Descril:)ed from one male sent me for identification by 
Prof. H. A. Surface of Harrisbiu'g', Pa. It was bred by him 
from a cocoon thought to be that of a species of microlepidopteron 
cohcctcd at Saegerstown, Pa., January 30. As all members of 
the grou]) are ]3arasites of leaf-hoppers, feeding externally and 
later spinning their own cocoons, it is probable that the ])arasite's 
own cocoon was mistaken for that of a moth.
