32 EBERHARTS OD TUNES OF 



comes out of the egg in five or six days, when it makps its 

 first meal on a part of the empty egg shell, and then at- 

 tacks the softer portions of the grape-vine leaves. When 

 first hatched, it is one-fifth of an inch long of a pale yel- 

 lowish-green color, with a large head and having a long 

 black horn near its posterior extremity, half as loDg as its 

 body. As it increases in size, the horn becomes relatively 

 shorter and changes in color; the markings of the larva 

 also vary considerably at each moult. When full grown it 

 is about two inches long, with a rather small head of a pale 

 green color, dotted with yellow, and with a pale -yellow stripe 

 down each side; the body is green, of a slightly deeper 

 shade than the head, and covered with small yellow dots 

 or granulations; along the sides of the body these gran- 

 ulations are so arranged as to form a series of seven 

 oblique stripes, extending backwards, and margined behind 

 with a darker green. A white lateral stripe with a dark- 

 green margin extends from just behind the head to the 

 horn near the other extremity. Along the back are a series 

 of seven spots, varying in color from reddish to bluish 

 green, granulated with black in front, and sometimes yellow 

 behind and at the tip. This larva has the power of draw- 

 ing the head and next two segments within the fourth and 

 fifth, causing these latter to appear much distended; the 

 feet are red, the pro-legs pale green. Some specimens 

 especially among those of the later brood, will be found 

 exhibiting remarkable variations in color; instead of green 

 they assume a delicate reddish-pink hue, with markings of 

 darker shades of red and brown, which so alter their ap- 

 pearance that they might at first be readily taken for a dif- 

 ferent species ; a careful comparison, however, will show the 

 Fame arrangements of dots and spots as in the normal
