254 LEPIDOPTERA. 



egg was about one-tenth of an inch long. The head is medium 

 sized, black, and shining ; the body above is dark brown, with 

 transverse lines of a paler color, especially on the anterior seg- 

 ments ; it is thickly covered with stout hairs of a pale brownish 

 color ; between the first and second moult it is one-fourth of an 

 inch long. The head is bilobed, shining, black and hairy, and 

 the body above is greenish black, the greenish tinge most 

 apparent on the second and third segments, with a few small 

 yellowish dots along each side, and transverse rows of strongly 

 elevated, black tubercles, emitting numerous short, black hair- 

 like spines. 



"The under surface is similar to the upper ; the feet are black 

 and shining, and the prolegs are black, tipped with a paler hue. 

 After the second moult there are two fleshy tubercles on the 

 second segment much longer than the others, being three or 

 four times their length, which are covered throughout with 

 small hair-like spines. The yellowish spots along the sides of 

 the body assume more of an orange tint, and there are one or 

 two faint, longitudinal streaks of the same color along the sides 

 close to the under surface, and between the rows of large, raised 

 tubercles, are many smaller ones which are also black and 

 appear but slightly raised. August 7th the larva was full- 

 grown. The head is, at this period, slightly bilobed, black, 

 shining, and covered with short, fine, black hairs. 



"The body above is dark greyish brown, beautifully spotted 

 and dotted with deep velvety black ; the second segment, has 

 two long, fleshy horns, yellowish white at base, black above, 

 covered with minute, blackish, hair-like spines. The third and 

 fourth segment, have each four whitish spines tipped with 

 black, those on the sides placed on the anterior portion of 

 the segment, those above about the middle. All the other seg- 

 ments have six whitish spines, excepting the terminal one, 

 which has four. All the spines have fine branches of a black 

 or brownish black color and are about one-third the length of 

 the fleshy horns on the second segment. A pale line extends 

 along each side from the fifth to the terminal segments close to 

 the under surface. The under surface is brownish black, darker 

 on the anterior segments ; feet black and shining ; prolegs 

 brown, with a shining band of brownish black on the outside.
