226 CATERPILLARS AND THEIR MOTHS 



The egg was small, hemispherical, flat on the under 

 side, greenish yellow, with a white bloom over it. 

 Under the lens it showed honeycomb reticulation. 

 Putting it safely away, she looked for others, but 

 found none. 



The egg hatched in four days, at noon, but the 

 young caterpillar could not be identified at this 

 stage. It was really exciting, for we could hardly 

 hope to carry one larva through all its stages, — at least, 

 the chances were against it, — and if this were hidentata 

 we were — or might be, if it lived — the first to publish 

 its history. 



This much-tended crawler was less than a quarter 

 of an inch long. Its head was dark brown, lighter 

 down the middle. Its body was green, sparsely hairy, 

 with a shining-looking brown spot on the dorsum of 

 the fifth segment, a similar one on the substigmatal 

 line of the same segment, and a dorsal one on the 

 eleventh segment. The legs and props were shining 

 brown, the anal props being drawn out very thin and 

 making a taper end to the body. They were carried 

 in the air when the caterpillar crawled, the whole 

 end of the body, from the fourth pair of abdominal 

 props, being raised when in motion. 



The caterpillar molted in three days, August 16. It 

 was one fourth of an inch long, with a large, nearly 

 round, bilobed head, pale olive-green, with face-lines of 

 darker olive, very smooth. Its body was pale glassy 

 green, darker on the dorsum. The fifth segment had 

 on the dorsal line a large, brown, double tubercle or 

 prominence, and a substigmatal one on each side. The 

 eleventh segment had a brown dorsal hump, the tenth
