tween each striae distinctly indented. The egg was contracted at the apex, 

 the striae protruding at the tip all around, beyond the body of the egg. The 

 eggs became much darker in color before the larvae appeared. 



The larva hatched in six or seven days, and when fresh from the egg was 

 about one-tenth of an inch long. Head medium sized, black and shining. 

 Body above dark brown with transverse lines of a paler color, especially on 

 the anterior segments ; and thickly covered with hair-like spines of a pale 

 brownish color. 



Between the first and second moult its length was one-fourth of an inch. 

 Head bilobed, shining, black, and hairy. Body above greenish black, the 

 greenish tinge most apparent on 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. Under surface 

 similar to upper; feet black and shining; prolegs black, tipped with a paler 

 hue. 



After the second moult there were two fleshy tubercles on second segment 

 much longer than the others, three or four times their length, and covered 

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

 of body assumed more of an orange tint, and one or two faint longitudinal 

 streaks of the same color appeared along the sides close to under surface. 

 Between the rows of large raised tubercles were many smaller ones, also 

 black, appearing but slightly raised. 



August Tth. Appearance of the full-grown larva. — Length, eight-tenths 

 of an inch. Head slightly bilobed, black, shining, covered with short fine 

 black hairs. 



Body above dark greyish brown, beautifully spotted and dotted with deep 

 velvety black, second segment with two long fleshy horns, yellowish white at 

 base, black above, covered with minute blackish hair-like spines. The third 

 and fourth segments have each four whitish spines tipped with black, those 

 on sides are placed on the anterior portion of segment, those above about the 

 middle. All the other segments have six whitish spines, excepting the ter- 

 minal 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 second segment. A pale line extends along each side from fifth to termi- 

 nal segments, close to under surface. The under surface is brownish black, 

 darker on anterior segments; feet black and shining; prolegs brown, with a 

 shining band of brownish black on the outside. 



The chrysalis is about half an inch long, of a pale grey color, dotted and 

 streaked with black. At the tip, beyond the base of antennae, are two large 

 conical tubercles. On the thorax, also, are several smaller pointed tubercles, 

 and a double row along the abdomen of a similar character, those on the third
