144 CATERPILLARS AND THEIR MOTHS 



pillars ate their shells and drank water eagerly. They 

 rested on the upper side of the leaf, on the midrib. 



The first molt occurred eight days after hatching, 

 and the larvae ate their skins except the masks. The 

 head was large and round. The body was bright 

 green, granulated with whitish, and had a dark dorsal 

 line, while the lateral lines were whitish. The obliques 

 showed faintly. The horn was dark brown, light at 

 base except in front, and set thickly with spines. 

 Two days later the granulations became yellow. The 

 legs and mouth-parts were pinkish. 



A week from the first molt came the secondo The 

 head was plain green. The body was yellow-green, 

 very rough with granules, and had a lateral line and 

 obliques of yellow granules, the obliques meeting on 

 the dorsal line, the last pair being edged above with a 

 little brown near the horn. The horn was brown, 

 lighter at the base, and very spiny. Two days later 

 the obliques were faintly edged with reddish brown, 

 and the lateral line was visible on the thoracic seg- 

 ments only. The horn and legs became red. 



Six days later the third molt took place. The head 

 was pointed and very yellow-green, with yellow face- 

 lines; the thoracic segments were yellow-green, and 

 the rest of the body was apple-green, whiter below, 

 thickly covered with yellow granules. The anal shield 

 was edged with yellow. The horn was reddish and 

 very rough. The obliques were clearly edged above 

 with violet. A week later the granules were all white, 

 except on the thoracic segments and anal shield. The 

 horn was redder, and the obliques were yellow edged
