DOLBA HYL^US 159 



The second molt was a week after the first. This 

 time they had seven pale yellow- white obliques, the 

 last being whiter and wider than the others and ex- 

 tending np the horn. There was a dark dorsal line 

 from head to horn, and the horn was ijrowner. 



The third molt, six days later, made them an inch 

 long, a trifle longer when they crawled. The head 

 was green, the body pale green on the dorsum with a 

 dark green dorsal line, and deeper green elsewhere, 

 with a yellow lateral line broken by the yellow obliques, 

 which were edged above with dark green. The horn 

 was long, sharp, and rough, green at the base, almost 

 black elsewhere. The legs and props were green. The 

 body was granulated with yellow, and most densely 

 on the thoracic segments. In this stage the yellow 

 horizontal lateral line disappeared from the abdominal 

 segments after two days. The last pair of obliques 

 became edged above with blue-black, and the head 

 gained blue-black granules. The legs became red- 

 brown at the tips. One caterpillar showed his indi- 

 viduality by having an olive-green horn, very pale at 

 the tip. 



Five days later the fourth molt occurred. The head 

 was round, green, granulated. The body was green, 

 and granulated with yellow on the thoracic segments, 

 venter, and anal shield. The dorsum was very white- 

 green, with a deep green dorsal line. There were no 

 yellow lateral lines. The obliques were whiter, edged 

 above with dark green, then a faint blue-l)UTck line, 

 the last one whiter, wider, and having a marked blue- 

 black line. The spiracles were blue-black encircled 

 with white, inconspicuous even now. The caudal horn
