The antennae are long, pectinated for half of their length in 

 the male, and shortly verticillate in the female ; between them 

 is a diverging tuft of hair. The palpi are rather short, and the 

 abdomen is obtuse, and tufted at the tip. The wings are 

 entire, and the fore-wings are provided with one or two teeth 

 on the inner margin, and are marked with oblique transverse 

 lines. The larva is thick, with a large head and sixteen legs. 

 It has bifid tubercles on the fifth and eleventh segments, 

 and the sub-dorsal lines are much waved ; the pupa is sub- 

 terranean.

This Moth is a native of Brazil. It expands about an inch 

 and a third. 



The fore-wings are brown and rather pointed, with the hind 

 margin convex and obliquely curved, with a strong tooth at 

 the hinder angle, and a deep concavity between this and a large 

 rounded projection on the middle of the inner margin. Only 

 the first line is distinct ; it runs very obliquely outwards from 

 the costa to the tooth on the inner margin. The reniform 

 stigma is indistinctly visible, and a zig-zag line runs obliquely 

 from the costa near the tip, approximating to the first line on 

 the inner margin. The hind-wings are grey, darker towards the 

 margins, with a black line on the base of the fringes, and a 

 very distinct long patch of black scales before the extremity of
