148 LEPIDOPTERA. 



upraised scales, grey-brown, striped across the collar, and 

 broadly down each side of the very large and long shoulder- 

 lappets, with dull white ; abdomen short, thick, black, very 

 downy, the back of each segment edged with yellow or rusty- 

 orange, and the whole surface shaded with scattered white 

 hair-scales ; anal tuft hoary. Fore wings narrow from the 

 base, expanded toward the anal angle ; costa faintly concave 

 to near the tip, -where it becomes a little arched ; apex bluntly 

 rounded ; hind margin very long, not very oblique till below 

 the middle, which is faintly elbowed, and from which it 

 curves oiF with a long sweep right round the w^ide anal angle ; 

 dorsal margin straight ; white, with three very oblique trans- 

 verse slate-grey stripes ; the first arising broadly on the 

 dorsal margin near the base, and running inward upon every 

 nervure, tapers off a little as it approaches the costa far 

 beyond the middle ; the second is broad throughout but 

 least so at the costa, and parallel with the outer edge of the 

 first ; and the third, almost equally broad, lies along the hind 

 margin ; nervures grey-black ; discal spot a similar slender 

 crescent ; costa dusted with the same colour ; cilia pale slate- 

 grey dashed or tipped with white. Hind wings narrow and 

 much elongated, rather squared at the apex, and rounded 

 behind ; white, with the nervures slate-grey ; across the 

 middle is a slender stripe of the same colour, often visible 

 principally upon the nervures ; another stripe, broader, of a 

 paler tint of the same colour, or sometimes divided by a white 

 intersecting line, lies along the hind margin ; cilia of the 

 same colour. Female nearly apterous, but possessed of four 

 minute useless flaps of wings, black, but fringed with long 

 white hairs ; antennas quite simple; head and thorax black 

 but with abundant white hair-scales ; these also are scattered 

 over the abdomen, which otherwise is black, thick, and ovate, 

 the edge of each segment marked by a yellow line; the 

 lower portion of the body is clothed with longer browm hair- 

 scales ; legs black, but feet pale brown.
