Genus CALLOPISTRIA Hubner (1) Callopistria floridensis Guenee, Plate XXIX, Fig. 61, male. As the name indicates, the species is from Florida. Genus METATHORASA Moore A genus represented in both hemispheres, and particularly well in Asia. (1) Metathorasa monetifera Guenee, Plate XXIX, Fig. 62, female. A native of the Appalachian subregion, ranging from Canada to Florida. Thus far it does not appear to have been reported from any locality west of the Allegheny Mountains. I found it one summer quite abundantly at Saratoga, New York. Genus EUHERRICHIA Grote A small genus represented by three species in our fauna. Euherrichia granitosa occurs in Florida; Euherrichia cervina on the Pacific slope; and the species, which we figure, from Canada to Florida and westward to Colorado. (1) Euherrichia mollissima Guenee, Plate XXIX, Fig. 63, male. Syn. rubicunda Walker. The specimen depicted was taken in the neighborhood of Saratoga, N. Y.
