THIS genus was first characterized by Dr. Leach, 

 and has been adopted with 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 under 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 fringe is gree'nish -yellow, and the antennas 

 reddish-brown, particularly in the male.
