This genus was first cliaracterized by Dr. Leach, 
and has been adopted ivith some modifications by 
most succeeding writers. The species which it 
formerly embraced are noted for their beautiful tints 
of green, which caused them to be known by the 
appellation of Emerald-moths. These, however, are 
now distributed in other genera, and the only one 
left imder the old designation is the fine insect 
represented on the adjoining plate. The wings 
generally exceed two inches in extent, and some- 
times are two inches and a half in the female ; the 
surface deep grass- green, with two rows of whitish 
spots extending across both wings, rather behind the 
middle ; on the disk of each there is an obscure 
crescent-shaped spot of a deeper green than the 
rest ; the Singe is greenish -yellow, and the antennas 
reddish-brown, particularly in the male.
