ATHYRMA. 
Athyrma, Hiibner, Verz. bek. Schmett. p. 267 (1816); Guénée, Sp. gén. des Lép. vii. p. 261; 
Walker, Cat. xiv. p. 1416. 
This genus is represented in Central America by two species, one of which is distri- 
buted from Mexico to Panama. 
1. Athyrma adjutrix. 
Phalena Noctua adjutriz, Cram. Pap. Exot. iii. p. 144, t. 272. ff. BE, F’. 
Athyrma adjutriz, Hiibn. Verz. bek. Schmett. p. 267; Guén. Sp. gén. des Lép. vii. p. 2627; Walk. 
Cat. xiv. p. 1416”. 
Hab. Mexico, Paso de San Juan (Schaus), Coatepec (Brooks) ; Guaremana, Volcan 
de Atitlan 2500 to 3500 feet, Pantaleon 1700 feet (Champion); Costa Rica, Volcan de 
Trazu 6000 to 7000 feet (Rogers); Panama, Volcan de Chiriqui below 4000 feet 
(Champion), Chiriqui (Ridbe).—Gutana, Surinam 123, 
Walker states * that A. dormitrix, Guén., may be a variety of this species. 
2. Athyrma tuberosa. — 
Athyrma tuberosa, Feld. & Rogenh. Reise der Nov., Lep. t. 117. f. 21, Erkl. der Taf. 117. no. 21°. 
Hab. Panama, Chiriqui (Ribbe, in mus. Staudinger).—Amazons 1, 
Dr. Staudinger’s specimen from Chiriqui is slightly darker than Felder’s figure. 
OPHIUSA. 
Ophiusa, Guénée, Sp. gén. des Lép. vii. p. 263 (1852) ; Walker, Cat. xiv. p. 1418. 
Walker included forty-seven species in this genus, which is represented in nearly all 
parts of the globe ; two only are known to me from within the limits of our fauna. 
1. Ophiusa detinquens. 
Ophiusa delinquens, Walk. Cat. xiv. p. 1423". 
Hab. Mexico, Acapulco (J. J. Walker), Cordova (Riimelt); Panama, Bugaba (Cham: 
pton).—VENEZUELA }. 
This species varies very considerably in colour ; some specimens being quite pale and 
others very dark. 
2. Ophiusa antica. 
Ophisma (?) antica, Walk. Cat. xxxi. p. 954°. 
Hab. Mexico, Acapulco (7. J. Walker).—VEneEzvrta }. 
Our specimen from Acapulco does not differ from Walker’s type in the National 
Collection. I think it most likely that 0. antica will prove to be not distinct from 
O. delinquens.
