184 HETEROCERA. 
Boisduval has renamed the species figured by Cramer (loc. cit. t. 77. f. B, 2) as 
Jo episcopus; but, upon comparison with my specimens from Bogota and Ecuador, I 
feel certain that the species is distinct from G. abas, Fabr., and should stand under 
Dr. Felder’s name. Cramer’s figure is not very good. 
HYPERCHIRIA. 
Hyperchiria, Hiibner, Verz. bek. Schmett. p. 155 (1816). 
Io, Boisduval, Ann. Soc. Ent. Belg. xviii. p. 206 (partim). 
Two species (H. nausica and H. io, from Surinam) were placed under this generic 
name by Hiibner. I take Attacus nausica, Cram., as the type of Hyperchiria ; it 
differs greatly both from Automeris and Gamelia. 
Walker, in my opinion, erroneously placed these two last-named genera aS synonyms 
of Hyperchiria. In our country the genus is represented by a single species, which we 
now trace northwards to Mexico. 
1. Hyperchiria nausica. 
Phalena-Bombyx Attacus nausica, Cram. Pap. Exot. iii. p. 97, t. 249. ff. D, E(¢?), et t. 3038. ff. B, 
C (gy). 
Hyperchiria nausica, Hiibn. Verz. bek. Schmett. p. 155; Walk. Cat. vi. p. 18097. 
Io nausica, Boisd. Ann. Soc. Ent. Belge, xviii. p. 229°. 
Hab. Mexico, Cordova! (Hége).—Gu1ana, Surinam !?3, Cayenne®; Braz ?. 
The specimen before me from Cordova agrees well with Cramer’s figures D, E, 
excepting that the abdomen is banded with black on each segment and that the black 
markings are not quite so distinct; on the underside it is almost identical. The larva, 
according to Stoll, lives upon Anacardium giganteum, and is described as “‘ Verte ou 
d’un vert pale, garnie de quatre rangées d’épines rameuses de la méme couleur. L 
dernier segment est marqué d’une petite raie noire et d’une autre incarnate, plus grande, 
de forme semilunaire.” | 
ANTHERZEA. 
Antherea, Hiibner, Verz. bek. Schmett. p.152; Walk. Cat. v. p. 1239. 
This genus now contains a large number of Eastern species; but from the New 
World I only know of one (A. chapata), from Mexico, that I can with certainty refer 
to it. This last-named species agrees very well generically with the male of A. mylitta 
from Ceylon; the neuration appears to be identical. 
Hubner placed three species (A. mylitta, A. paphia, and A. jana) under this generic 
name, and Walker twenty-one, all Asiaticand African forms. The American species I 
include in it was placed doubtfully in Attacus by Walker.
