ISOGONA.—CEROMACRA. 391 
Of this species we have only received one specimen; it agrees with others from 
Chiriqui in Dr. Staudinger’s collection. 
The Guatemalan example is figured. 
EPIDROMIA. 
Epidromia, Guénée, Sp. gén. des Lép. vii. p. 325 (1852) ; Walker, Cat. xiv. p. 1518. 
Guénée founded this genus upon two species, both from Brazil; and several others, 
from the Amazons, have since been described by Butler. Some of the Tropical- 
American species referred by Walker to Thermesia also belong to it. Three are here 
recorded from Central America. 
1. Epidromia distincta. 
Epidromia distincta, Butl. Trans. Ent. Soc. Lond. 1879, p. 537. 
Hab. Panama, Volcan de Chiriqui (Trétsch, in mus. Staudinger).—Amazoys }. 
A specimen from Chiriqui in Dr. Staudinger’s collection is almost identical with 
Butler’s type in the National Museum. 
2. Epidromia tinctifera. 
Thermesia tinctifera, Walk. Cat. xv. p. 1570'. 
Hab. Mexico, Valladolid in Yucatan (Gawmer); GuateMata, in the city (Rodriquez), 
Zapote (Champion); Honpuras (Dyson1); Panama, Chiriqui (Zrétsch, Ribbe, in mus. 
Staudinger). 
This species varies considerably in colour. 
3. Epidromia suffusa. 
Thermesia suffusa, Walk. Cat. xv. p. 1561'. 
Hab. Panama, Chiriqui (Ribbe, in mus. Staudinger).— ANTILLES, San Domingo 1. 
It is quite possible that this insect is only a pale form of the preceding species. 
CEROMACRA. 
Ceromacra, Guénée, Sp. gén. des Lép. vii. p. 827 (1852) ; Walker, Cat. xiv. p. 1519. 
This genus includes one species only, the Phalena Bombyx tymber of Cramer.
