DESCRIPTIONS OF NEW SOUTH AMERICAN MOTHS. By William Schaus,Of Timckenham, England. The following 470 species are described from my collection, which Ihave deposited in the United States National Museum. They comprisespecies from the families Saturniidic, Citheroniidiv, Syntomida% Litho-siidne, Nolida?, Arctiida^, Notodontida^ Melalophida?, Eupterotida?,Lasiocampichv, Lacosomida\ Dalcerida\ Aedida^, Megalopygida\ Cos-sidse, and Psychida\ Those of other families will appear later. 1 amindebted to my friend Sir George F. Hampson for kindl}' examiningthe species of Syntomida\ Lith()siida\ Nolida\ and Arctiida\Family SATURNIID.E.Genus ROTHSCHILDIA Grote.ROTHSCHILDIA AROMA, new species.Body brownish red, the abdomen irrorated with lilacine. Collarwhite. A wdiite transverse basal band on al^domen; anal hairs white;a lateral white band spotted with red-brown; ventral white marks.Wings bright reddish brown; the transparent spots siibtriangular,outlined with white and black, extending on to postmedial line; thelines broad, white, medially edged with black. Primaries: costa irro-rated with gre}'; the lilacine and grey irrorations lieyond postmedialbarely extending above vein 5. This species is most nearly allied toRothscldldla Icheaui Guerin, but the primaries are more falcate andmore brilliantly colored.Expanse.?Male, 123 mm.Hahltat.?Honduras.%?..?Cat.

Primaries: the postniedial line is straighter above vein 5 thanin RothschikUa liesperus Linna?us, and is not followed above that veinby the lilacine irrorations; the apex is not so falcate as in kesperusmale, and the irrorations beyond the postmedial are not distinctlydentate as in hesperus, and aurota Cramer.
