patches. The moths appear in July, when, after pairin^^, 

 tlie female deposits her eggs singly on the leaves of the gra[)e- 

 vine, or Virginia creeper, J.mp6/opsi8 quinquefolia, wheve they 

 shortly hatch, producing small green larvae of a pinkish hue 

 along the sides, and with a very long pink horn at the tail. 

 As the caterpillar increases in size, the horn becomes shorter.

and after a time curves round, as shown at c, Fig. 259. As 

 the larva approaches maturity, it changes to a reddish-brown 

 color, and after the third moult entirely loses the caudal 

 horn, which is replaced by a glassy, eye-like spot. The 

 mature larva, when in motion, as shown at a in the figure, 

 will measure nearly four inches in length, but when at rest it 

 draws the head and two adjoining segments within the fourth, 

 as shown in the figure at 6, which shortens its body nearly 

 an inch, giving it a very odd appearance, with its anterior 

 portions so blunt and thick. It is of a rich reddisli-brown 

 color, of a lighter shade along the back, with five nearly 

 oval cream-colored spots along each side from the seventh to 

 the eleventh segment inclusive. On the anterior segments 

 there are a number of black dots; a dark, polished, raised.
