LEPIDOPTERA. 
Ophiusa : with the “ anterior wings brown, with a longitudinal green daub ; posterior 
pair yellowish, with a lunar spot and border of black.” Expanse of the wings, 
3 inches. 
Donovan observes that “ this moth agrees entirely with the Noctua Dioscoreae of 
Fabricius, (Ent. Syst . t. 3, p. 2, p. 16, n. 26.) except in having a large green streak 
on the upper wings. It appears, indeed, to have been hitherto confounded with that 
species, either as a sexual difference, or variety ; but we are persuaded it is neither. 
Both sexes of N. Dioscoreae, in particular, have occurred to our observation, without 
this streak. Found in Bengal.” It should be observed, however, that Fabricius, not 
only in this, but also in the allied species Materna, (figured by Drury, vol. 2, t. 13.) 
states that the colour of the anterior wings is liable to great variation. The emargina- 
tion of the posterior margin of the fore wings in this figure, is also noticed by Fabricius 
under Dioscoreae, and is probably a sexual character.
