190 CATERPILLARS AND THEIR MOTHS 



In all the years since we have never found a myops 

 on that tree, but we never pass it without a feeling 

 that we may see another procession. We often find 

 single caterpillars on hazel-bushes which grow in a 

 clump near a big rock, and on wild-cherry trees, espe- 

 cially young trees and saplings. 



The first eggs we had were sent us by a friend ; the 

 second lot we found on the under side of leaves, eight 

 on one leaf. The eggs were ovoid and pale green, and 

 soon showed a white line — the caterpillar. The egg- 

 period was fifteen days in the first instance; in the 

 second we had no means of knowing ; a third brood 

 hatched in seven days. The first lot hatched the last 

 week in June, the second on the 28th of July, the third 

 about the middle of July. 



The caterpillars were pale yellow, becoming yellow- 

 green after eating, and had short sette all over, as do 

 all young sphingid larvae. The caudal horn was pink- 

 ish, rough, short, and thick. They ate nearly all of 

 their shells, drank eagerly, and ate holes in the paren- 

 chyma of the wild-cherry leaves, leaving the fibers un- 

 touched. They fed on the under side of the leaves 

 always, clasping a vein with their props ; but after a 

 day or two they crawled to the edge of the leaf and ate 

 curves out of it. They always rested at some distance 

 from the feeding-place. Their anal props had "trains" 

 like those of T. modesta. In a day or two faint yellow 

 lines appeared on the side of the thoracic segments, 

 and faint yellow obliques. 



The first molt occurred five days after hatching. 

 The first brood was unchanged, until three days later, 

 when faint red spots began to show. 



The second brood had the heads, first and anal seg-
