head and anal segment. On the tliird day a 

 whitish siibdorsal line showed faintly, ex- 

 tending from head to liorn. The head was 

 like old ivory in color and the body was 

 almost as glassy green as that of a young 

 Thyreus abbottii . 



June iSth. — First moult. Head round, 

 bilobed, orange-brown, smooth and large. 

 Body, \ inch long, slender, dark green, 

 speckled with lighter green, and had a bilobed 

 horny plate of lighter- green on the dorsnm 

 of first seginent. There was a faint yellow 

 stigmata! line on first three segments, and a 

 bright yellow subdorsal line from head to 

 horn, in most cases, but some larvae had no 

 yellow lines Feet and props of lighter green. 

 Horn lighter green at base, black and rough 

 above. Some larvae had the anal shield 

 orange-brown. Ate very little. 



June 22d. Second moult. Larvae k inch 

 long. Head large, round, bilobed, orange- 

 brown, speckled with lighter. Body almost 

 black, speckled with yellow-white. Sub- 

 dorsal line of bright yellow, widening into a 

 yellow patch on each segment. Stigmatal 

 wavy line of bright yellow. Body tapered 

 from the third segment to the head. Feet, 

 props and anal shield orange-brown. Horn 

 orange-brown at base, black and rough 

 above. Gave woodbine, which they ate 

 eagerly, leaving the grape for it. 



June 27th. — Third moult. \ inch long. 

 Head round, large, bilobed, deep orange- 

 brown, with white dots and many setae. 

 Body black, with transverse lines of white 

 dots, velvety black on the dorsum and be- 

 tween the segments. Subdorsal line of bright 

 yellow, widening into a spot on each seg- 

 ment. Bright yellow stigmatal line wavy 

 and broken. Feet and props orange-brown. 

 Horn black, shining, rough, still ending in 

 two setae. Anal shield black, speckled and 

 edged with yellow-white, and looking very 

 high above the props. 



July ist. Fourth moult. i4 inches long. 

 Head orange-brown, speckled with lighter, 

 small, round. Body pale green, with black 

 transverse lines from stigmatal line to dorsal 



band. Dorsal band velvety black, giving off 

 a short band of black, on each side, between 

 each two segments. Subdorsal and stigmatal 

 lines yellow, the yellow dot of the former 

 occurring in the short black band. Dorsal 

 plate on first segtnent orange-brown, speckled 

 with lighter, as were the anal props and 

 shield. Feet and abdominal pi-ops orange- 

 brown. Horn slender, rough, orange-brown 

 at base, black above, ending in two tiny 

 tubercles. Spiracles yellow-white, encircled 

 with black. Venter paler, and mottled, as 

 well as striated, with black. One larva had 

 the head, dorsal plate, and anal props and 

 shield, green speckled with orange, the body 

 hardly striated with black, the yellow lines 

 very pale and greenish, and on each segment 

 an orange spot. The dorsal black band 

 was very faint and divided by a dorsal line of 

 green, but the short black bands were very 

 velvety and deep in color. In this stage all 

 the larvae had a habit of moving the caudal 

 horn as a finger might be moved, not merely 

 depressing it backwards. They were very 

 active, dropped from the stems when dis- 

 turbed, and jerked their heads from side to 

 side like larvae of T. abbottii. The body 

 still tapered from the third segment to the 

 head. 



July 5th. Fifth moult. \\ inches long. 

 Head, dorsal plate on first segment, anal 

 props and shield orange-brown, speckled 

 with lighter. Body mustard-yellow with 

 short blue-black bands between the segments. 

 Dorsal line very fine and yellow. Subdorsal 

 and stigmatal lines yellow, broken, with a 

 yellow dot on each segment. Feet, props, 

 and horn orange brown, the horn longer in 

 proportion, and rough. Spiracles orange, 

 circled witli black. The second form had the 

 head, dorsal plate, anal props and shield 

 green, dotted with lighter; feet, abdominal 

 props, and horn dull, pale orange. Body 

 green, with much less black striation ; dorsal 

 line broad, green, in a wide, but less black 

 band. Subdorsal yellow line contracted 

 into a yellow spot, enclosing an orange 

 dot set in the short black band on each
