half inches. It much resembles that of Pandoras, No. 133, 

 and feeds also on the Virginia creeper [Ainpelopsis qydnquefolia) 

 as well as on the grape-vine. The egg is laid on the under 

 side of the leaf in July, and the young larva, when hatched, 

 is of a light-green color, with a very conspicuous reddish- 

 brown horn, half as long as its body, which, as the larva 

 increases in size, becomes shorter, and finally disappears, its 

 place being occupied by a polished tubercle with a central 

 black dot. The mature larva varies from a pale straw-color 

 to a reddish brown, the color growing darker down the sides,

becoming deep brown as it approaches the under surface. An 

 interrupted line of brown runs along the back, and another 

 unbroken one extends along each side ; below this latter there 

 are six cream-colored spots, as shown in the figure, one on each 

 segment, from the sixth to the eleventh inclusive. The body 

 is much wrinkled, and dotted with minute spots, which are 

 dark on the back, lighter and annulated at the sides. The 

 head and next two segments are small, and are drawn within 

 the fourth when at rest, as seen in the figure. It becomes full 

 grown during the latter part of August or early in September, 

 and just before undergoing its next change assumes a beau- 

 tiful pink or crimson color. 



Leaving the vine, it descends to the ground, where it buries 

 itself to the depth of several inches, and, having formed for 

 itself a smooth cell, changes to a chrysalis (Fig. 261) of a 

 dark, shining, mahogany color, with the anterior edges of the 

 segments along the back roughened wdth minute points, and 

 with a short, blunt spine at the extremity. The insect usually
