Body rather slender. Palpi porrect, rather slender. Legs 

 slender. Fore wings rather narrow, straight along the costa, 

 rounded at the tips, very oblique along the exterior border ; second 

 inferior vein about thrice further from the third than from the first. 

 Hind wings extending far beyond the abdomen, with very long

The two species of Eudcemonia differ much in structure, and 

 E. Semiramis ought probably to be transferred to the genus Tropcea. 

 E. Argus is perhaps the most aberrant form of all the Saturniidce.
