and others were found by the writer at Maplewood, New Jersey. Alto- 
gether 449 cocoons were obtained during the winter of 1898-99. These were 
allowed to remain out of doors in Cambridge (Mass.), where they were 
exposed to the winter’s cold, and then on May 5th they were taken to Logger- 
head Key, one of the Dry Tortugas Islands, Florida. 
This situation was most favourable for the prosecution of the experiments, 
for this insect does not extend south of the Carolinas, and thus the moths 
were separated many hundreds of miles from others of their species, More- 
over, Loggerhead Key is a small sandy island surrounded by many miles of 
ocean, and thus no interference with the experiments could come from the 
outside. 
‘The cocoons were hung under the shade of some trees, where they were 
protected from the direct rays of the sun, It was remarkable that all but 
five of the moths (three females and two males) issued from the cocoons 
during the early morning hours between sunrise and 11 o'clock, 
The following table will show the rate at which the moths issued from 
their cocoons :==
