 Spec. Gen. Lepid. Noct. ii. p. 411 (1852). 



In this genus the antennae are simple ; the palpi long, 

 ascending, recurved, and approximating; the abdomen flattened, 

 with the extremity pointed ; the legs thick, with strong 

 spurs. The wings are rather broad, indented, or slightly 

 denticulated ; the fore-wings are oblong, with the hind margin 

 only slightly curved. The larvae are green, with distinct lines, 

 and the penultimate segment often humped ; they live exposed 

 on trees and low plants. The pupae are enclosed in cocoons 

 of silk or rubbish on the surface of the ground.
