NOTES ON THE EARLY STAGES OF DEILEPHILA INTERMEDIA. 
BY ALLYN COX, WINDSOR, VT. 
THE eggs, laid June 17th, were small, oval, and green, turning dirty white before 
hatching. 
Three caterpillars hatched in six days, two dying almost immediately. The 
remaining caterpillar was whitish, growing greener as it ate. It did not eat the shell, 
but attacked the leaves immediately. It had whitish lines between the segments, 
a fold of whitish skin behind the head, and a short whitish horn. ‘The setae were 
invisible to the naked eye and the horn nearly so. It was about three sixteenths of

The first molt came in four days and the caterpillar was much more gaudy than 
before. ‘The dorsum was blue-green with whitish green subdorsal lines. ‘The sides 
were yellow-green with black spiracles. ‘The venter was blue-green and the legs and 
props yellow-green. ‘The head was small, round, bright green, and still had a fold 
of whitish skin behind it. In this molt the larva ate from the sides of the leaves. 
The second molt came in nine days. ‘The dorsum was blue-green, the sides were 
yellow-green granulated with white, and the venter was blue-green. ‘There was a 
greenish white dorsal line and greenish white subdorsals which had on each segment 
a bright yellow dot. ‘The stigmatal line was light green, but on the first two segments
