216 CATERPILLARS AND THEIR MOTHS 



down, and was yellowish, with a row of red-brown 

 tubercles on each dorsal edge. They did not eat their 

 egg-shells, which were just as prismatic as before, and 

 could not be distinguished from shells containing 

 larviB. The little caterpillars were given two bayberry- 

 leaves only, because they were so small that we feared 

 losing them if they had more surface to wander over. 

 They could be found without using a lens, but un- 

 trained eyes never saw anything but leaves in the box 

 until we pointed out the little crawlers, usually greeted 

 with : " That speck! Why, I can hardly see it ! " To 

 describe them a lens was needed. 



They hatched late in July, and molted nine days 

 later. Their backs looked pitted, and the red-brown 

 tubercles became slightly raised dots. A transverse 

 red line crossed the middle of the dorsum. Otherwise 

 they were not changed, and they had grown very little. 

 They ate their skins entirely. - 



In eight days they molted again. The head was 

 brown. The body was palest green, with a red-brown 

 bar across the first segment, red-brown subdorsals 

 from this bar to the anal end, two red-brown patches 

 about half-w^ay down the subdorsal lines, and two 

 similar patches near the anal end. There were no 

 tubercles. The head was drawn under the edge of the 

 first segment, which had a margin of brown and was 

 like a hood. There were no legs or props to be seen, 

 and the pale yellowish venter was contracted and ex- 

 panded, when the caterpillar crawled, with a wave- 

 motion. 



Six days later they molted a third time, the only 

 change being in size, and that a very slight one.
