on the 25th. An example confined in the Insectary went in-
, to the sand July 2, was a pupa July 3, and yielded an adult
on the night of July 14. This example simply illustrates
what occurs here every season, and probably what occurs in
Southern Kentucky somewhat earlier, if we may judge by
the observations thus far made.
Rearings in Insectary in 1909.
I The first brood reared is not to be understood as the first
` produced during the season, for I had myself secured an
· adult moth on July 14, as noted above, from eggs laid in
June, but unquestionably shows the number produced from
parent moths emerging from hibernating pupae somewhat late
in the season. In their case as in these rearings there is
little chance for the development of more than three broods
before cold weather comes on. ·
First Brood Rcared.
July 5, 1909, two individuals, emerging from pupae kept
over winter, were mated in a cage where they were provided
` with corn growing in a flower pot. Eggs were found on the
wire gauze of the cage July 7 and both moths were dead on
the 10th. Most of the eggs hatched on the 12th and 13th,
the total number hatching being about 125.
The history of the mated moths is as follows: (1) Egg
laid September 11, 1908. Hatched, September 15. Ready to
pupate September 27. Adult, a female, emerged July 4,
1909. (2) Egg laid September 11, 1908. Hatched Septem-
ber 15. Ready to pupate September 28. Adult, a male,
emerged July 5, 1909.
The individuals reared from these moths gave the following
record:
