This Moth is a native of Surinam, and measures about two 

 inches in expanse. The body is orange-tawny, and the antennae 

 are short and pectinated. The wings are broad, rounded at 

 the extremities, and not very long ; the fore-wings are white, 

 with four transverse orange-tawny bands, the last marginal, with 

 a short streak of the same colour at the end of the cell between 

 the first and second bands. Hind-wings white, with two nar- 

 row orange-tawny stripes about the middle. 



The larva is yellow, with longitudinal black lines, and tufts 

 of long black hairs, knobbed at the extremity, of which there 

 are two pairs near the head, and one pair near the tail. The 

 other hairs are long and simple, and there is a row of white 

 silky brushes of hair on the back. It feeds on the pine-apple. 

 The cocoon is white, and the silk is drawn out into a point at 

 both ends.
