66 BULLETIN NO. 4, DIVISION OF ENTOMOLOGY. 
On the day following our arrival at Palmares we took horses for 
Bonito, and arrived at our destination in the evening of the same day. 
The village of Bonito is a small one, on the southeastern border of 
the cotton-growing district. There being no hotel in the place, and it 
being impossible to arrange any other way to live and carry on our 
work, it was necessary to hire a house for these purposes. With con- 
siderable difficulty one was obtained, and preparation made for a short 
stay in the place. 
Arriving at Bonito on the 6th of January, it was my expectation that 
we would be able to leave for the provinces further south, in which 
much cotton is grown, within a couple of weeks at the most. It was 
found later, however, that in order to carry out our investigations sat- 
isfactorily it would be necessary to remain at Bonito much longer than 
I originally proposed. The fact that we had arrived so early in the 
season, as far as insects were concerned, also made it necessary to re- 
main here longer than would have been necessary had we come later, 
say in April or May, when insects are more active. 
Once in the cotton-producing country, there was no difficulty in learn- 
ing of the existence of caterpillars that destroy the plants. On the 
day following our arrival we visited some fields of cotton near Bonito, 
but, though we found various interesting insects injuring the plants, we 
were not able to find any indication of the existence of caterpillars. The 
people assured me that it was too early in the season, and that the 
weather was not of the kind favorable to these insects. The next day, 
however, Mr. Koebele found both larve and eggs, and, although they 
never appeared in large numbers during our stay at Bonito, from that 
time forth we found a few every day. In order to obtain as good a col- 
lection as possible of these insects in every stage of development, and 
of their parasites, we arranged to breed all we could find until our col- 
lections and observations were complete. At the same time especial 
efforts were made to find and raise caterpillars that feed upon other 
species of malvaceous plants. We had about a hundred breeding cases 
in our house for the different kinds of insects, parasites, We. 
We made observations on and collections of insects injurious to other 
industrial plants, such as oranges, coffee, corn, beans, tobacco, &e., and 
also of useful insects, such as bees. 
Sugar cane is not grown at Bonito in, sufficient quantity to allow of 
our doing much in regard to the sugar-cane disease, or insects affecting 
it. At the city of Pernambuco I learned that the Imperial Government 
had appointed a committee to investigate the causes and report upon 
remedies for the cane disease that has been doing great damage in this 
country for several years, but I was unable to find that anything had 
been made public in regard to what the committee had accomplished. 
The Pernambuco Agricultural Society had sent specimens of diseased 
cane to Germany for examination, and a short report from the gentle- 
man to whom they were sent was given me. This report says that a
