MACRODES *, 
Macrodes, Guénée, Sp. gén. des Lép. vii. p. [2 (1854) ; Walker, Cat. xvi. p. 4. 
Euclystis (pars), Hiibner, Verz. bek. Schmett. p. 341. 
Guénée included three species in this genus, and others have since been described. 
Macrodes seems to be peculiar to Tropical America ; some of its species are found over 
a very extended range of country, but they are nowhere common.
