This species is found throughout America as far north as the 

 Southern United States, as well as in the West Indies, and 

 measures about three inches across the wings. It is greyish 

 olive-brown, with the head flesh-coloured, and a stripe of the 

 same colour on each side of the thorax, which is clay-coloured 

 on the back, and yellowish-brown on the sides. The fore- 

 wings are greyish olive-brown, with several delicate parallel 

 lines, black and whitish alternately, extending from the base 

 somewhat obliquely to the apex. The hind-wings are black at 

 the base, and brown along the hind margin, these two colours 

 being separated by a row of light yellow triangular spots. The 

 fringes are white. 



The larva is delicate green, with numerous small reddish 

 brown longitudinal spots, yellow pro-legs, and a yellow oval 

 spot on each segment except the second and third, marked 

 with black above and below, and placed on a lighter ground. 

 Above these is a white stripe extending from the fifth segment 

 to the horn, marked with a row of five red-centred ocellatcd 

 spots ; in a line with these, on the fourth segment, is a larger 

 ocellatcd spot. The horn is red. The pupa is yellowish 

 brown,
