the entire back between tbe white lateral lines is claret red, and angulated 

 downwards on the sixth and ninth segments. 



A young specimen, found Sept. 10, 1841, had the whole back deep claret 

 red, bounded on each side by an irregular whitish line. The claret color 

 was angularly dilated on the sixth and ninth segments, and the tubercles on 

 the fourth and eleventh segments were also deep claret red. Length three 

 fourths of an inch. 



Sept. 10, 1842. Found on ground under button wood tree. Fed it with 

 leaves of button wood; figured Sept. 14. [PI. I, fig. 5.] Green, with a 

 broad salmon colored stripe on the back, edged and variegated with deep 

 red. Head reddish with a divaricating darker stripe each side. Legs 

 green, anal prolegs reddish, tipped with black. A few scattered purplish 

 dots on sides of body. Spiracles black, above which are the remains of 

 an irregular, broken, yellowish, lateral line. It rests "beneath a leaf, the 

 head and fore part of the body being curled sidewise. It touches the 

 anal prolegs in creeping, but does not seem to have any clinging power; they 

 are raised (as in the figure) when at rest. 



Sept. 16. Secured itself in a leaf, doubled and fastened with bands of 

 silk.

 between two orange colored tubercles, begins a white dorsal line, edged with 

 green, which also extends to the tip of the twelfth segment. The lateral 

 lines on the first three segments are edged within or above with pink or pur- 

 ple, and sometimes a narrow purple edge borders the lateral line above to 

 the end. On the eleventh segment two very minute orange tubercles, and 

 a few very small yellow ones on the sides of the body. A yellow lateral line 

 just above the feet on the first three or four segments. Spiracles orange. 

 The minute tubercles on the fourth and eleventh segments emit each a black 

 hair, and the other tubercles small whitish hairs. Twelfth segment with 

 the prolegs elevated when the insect is at rest.
