136 CATERPILLARS AND THEIR MOTHS 



gray horn, which was darkest at the tip. The horn was 

 slender, smooth, blunt at the tip, and almost as long as 

 the caterpillar. The setae were sparse. The larvae did 

 not eat their shells. 



In three days they molted, and were half an inch 

 long, slender and green. The head was round, bilobed, 

 and green. The body was green, with a lateral white 

 line and a faint stigmatal one from the head to the 

 anal shield. The setae were sparse. The legs and 

 props were green, the spiracles indistinct. The horn 

 was long, sharp, green at base, brown above, and rough 

 with black thorns or spines. There were seven pairs 

 of faint white obliques, the last pair wider and whiter 

 than the others. 



The second molt followed in four days, with little 

 increase of length. The head was green, and rough 

 with yellow granules. The body was green, with yel- 

 low granules, more numerous on the dorsum. There 

 was a yellow lateral line from head to horn. The 

 obliques were yellow. On the fourth segment, close 

 above the oblique, was a very noticeable large blue- 

 black dot. The caudal horn was green, with a black 

 tip and black spines. The legs and props were green. 

 A few days later yellow face-lines appeared, and faint 

 blue-black lines above some of the obliques. The 

 thoracic and anal segments were thickly dotted, rather 

 than granulated, with yellow. The legs gained a red- 

 dish brown dot on each. 



On the fourth day they molted for the third time, 

 and were one and one eighth inches long. The head 

 was now broader at the bottom than at the top, slightly 

 bilobed, green, with yellowish face-lines, and lightly 

 granulated. The body was green, slightly granu-
