This species expands about four inches and a half. It is 

 found in the Southern United States of America, and in the 

 West Indies, as well as in South and Central America. It 

 is of a rich brown, varied with white blotches and mottlings. 

 The base of the fore-wings is white, and there is a white band 

 before the middle, running from the costa to the inner margin, 

 which is broadly white beyond. A central band connects it 

 with another undulating white band passing from the costa to 

 the inner margin, which it reaches beyond the middle. The 

 brown area on the costa, bounded by these two bands, contains 

 a small round white spot, and there is a narrow waved white 

 streak on the brown patch near the apex of the wing. All the 

 white portions of the wings are more or less varied with 

 light brown in places. The hind-wings are brown, with the 

 base and a few marks near the anal angle white. The fringes 

 of all the wings are chequered with brown and white. The 

 moth varies considerably in the proportion and intensity of 

 the black, white, and brown of the wings. The head is brown 

 and white, and the thorax is brown, marked with a large trian- 

 gular patch somewhat resembling a dog's skull, and two white 

 dots in front of it. The abdomen is brown, with three large 

 round yellow spots on each side, and brown and white incisions. 

 The larva is green on the sides, merging into yellowish 

 above, with a series of oblique stripes on the sides of the 

 segments, consisting of white, purple, and pale blue. These
