half an inch from the tip, having within it a semicircular mark of a pearl colour. From this spot to the 

 anterior edge runs a serpentine line of white, bordered on the outer side with red. Between this and 

 the orange bar is a broad tinge of light purple. The other side, next the tip, is light brown, stained 

 with blood colour. From the black spot to the interior angle runs a black serpentine line, inclosing a 

 space of dark buff, between which and the dark buff margin is a light buff irregular streak. Posterior wings 

 similar to the superior, but the orange bar is redder and broader, running parallel with the external edge, 

 and is bordered on the inner side with white ; the part of the wing within this is deep rusty brown, 

 with a larger white spot in the middle, verged with black, and tinged behind with red brown. The 

 colour below the red bar is deep rusty brown, the border along the external edge being of a dark dirty 

 buff, whereon are two small dark lines, having an irregular indented line of the same dirty buff above 

 them. Tlie wings are entire. 



Under Side. The markings on all the wings are more distinct, and brighter than on the upper. The 

 posterior wings, and the major part of the anterior, being covered with dust-like buff hairs, except the 

 spots and buff margins round tiie edges. The posterior wings along the anterior edges being verged 

 with white, which becomes broader as it approaches the shoulders. 



The caterpillar of this fine moth feeds upon the wild American plum (Prunus Pensyl- 

 vanica), garden plum, &e. It is thick and fleshy, of a pale green colour, with a pair of 

 small blue spots on each segment, and with two rows of short and setose yellow dorsal tubercles. 

 One observed by Abbot, spun up on the 17th of June, and the moth came out on the 30th 

 of March following. The cocoon is attached to a twig. The outside web is coarse, and 

 the inner covered with silk, like a silk-worm's cocoon. Abbot states that this silk has been 

 carded, spun, and made into stockings, and that it will wash like linen. The species is, 

 however, too rare to be of any utility in Georgia, It is, however, much more abundant in 

 the neighbourhood of New York, and has been bred in England from some brought over in 

 the chrysalis state. It is difticult to rear it in confinement.
