24 THE CHINCH BUG. 
we have in South Australia the following facts regarding the codling 
moth, Carpocapsa pomonella, of which, though being still double brooded, 
" the winter caterpillars hatch into moths irregularly from the begin- 
ning of October until the middle of November and deposit their eggs 
accordingly, giving rise to a succession of young caterpillars until the 
beginning of December. About the third week in December the first 
moths of the second brood begin to appear and deposit eggs, and mem- 
bers of this second generation of moths continue hatching and egg lay- 
ing until the end of February." * 
My notes on the chinch bug in northeastern Ohio are as follows: 
Very young larvae, with what appeared to be their progenitors, were 
observed at Jefferson, Ashtabula County, within 11 miles of the shores 
of Lake Erie, on June 16, 1893, no advanced larva? being observed 
among them. On August 27, 1896, a few miles south, at West Andover, 
in the same county, I could find only adults in two days' search, though 
some of these showed by their color that they had but recently passed 
the pupal stage. In this latter locality, on May 7, 1897, the sexes were 
pairing, but no young were present, so far as could be observed, while 
to the south and west of this locality, on June 8 and 9, precisely the 
same conditions obtained as to the bugs, no young appearing at this 
time. Quite copious rains might have destroyed the young, but within 
15 miles of these localities, on July 14 of this year also, I found larva? 
after first molt and stages intervening between these and the adults. 
Near Youngstown, on October 3, 1897, 1 could find only adults and pair- 
ing was not in progress, and the insect was not pairing in Ashtabula 
County on August 27, 1896. June 9, 1898, only two very young larva? 
could be found at Salem, about 15 miles southwest of Youngstown. In 
the light of the information that has been gained by these observations 
I am led to doubt the occurrence of a second brood of young in north- 
eastern Ohio. Hatching is not fully in progress here before the 25th 
of June, only an occasional individual having passed the first molt 
before the 10th of July, t 
The late Dr. J. A. Lintner, in his studies of the outbreak of this 
insect in New York State in 1882 and 1883, seems to have relied much 
on the published habits of the species farther west (as indeed I have 
until receutly done myself), and made no exact studies of the species at 
that time; and in his annual report, where the outbreak is discussed, I

tUp to date of revision of proof sheets of this bulletin, October 17, 1898, no 
young of a second brood have been observed though careful search has been made 
from time to time in the fields and meadows of northeastern Ohio, and a large 
number of adults which developed in July and August, and since kept in confine- 
ment, have not only not reproduced but have shown no disposition whatever to 
pair. On the other hand, in southwestern Ohio, in the vicinity of Cincinnati, on 
September 24, where the species occurred in abundance, fully seventy-five per cent 
were pupye, the remainder being made up of larvae, some of them quite young, and 
adults in about equal proportions, some of the latter showing by their immature 
colors that they had but just passed the pupal stage.
