68 BULLETIN NO. 4, DIVISION OF ENTOMOLOGY. 
fact that I found that Dr. Antonio de Lacerda, a Brazilian gentleman 
living at Bahia, and one already well known for his intelligent interest in, 
and contributions to, entomology, informed me that he had bred a moth 
from a larva found by himself upon cotton in the suburbs of Bahia. 
Dr. Lacerda gave me this specimen. It is thesame as the larger cotton 
moth found by us at Bonito, and the same as the one common in the 
United States. 
I hoped, however, that we might be able to find the other moth in the 
immediate vicinity of the city. With this object in view, we examined 
all the cotton plants we could tind growing about the houses in the sub- 
urbs, and were fortunate enough to obtain a number, both of larvae and 
of eggs, which being bred, gave us both species of moth found at 
Bonito. We considered this sufficient evidence of the existence of 
both species of cotton moth at Bahia, and made arrangements to stop 
field-work and leave Bahia at once. 
In order to obtain all available publications upon entomology, histori- 
cal facts and statistics of production and exportation from the whole 
empire, and also to obtain the indorsement of his Excellency the Min- 
ister of Agriculture for the circular I proposed sending out asking for 
information, I found it necessary to continue my voyage to the capital, 
at Rio de Janeiro. Arriving in that city on the 29th of March, I pre- 
pared at once a circular containing fifty-two questions asking informa- 
tion in regard to the history of cotton culture in the country, the kinds 
planted, the methods of working and harvesting, the climate and soil 
found most favorable to it, the diseases and insects that attack it, and 
the remedies used for such evils; and also concerning oranges, varieties, 
methods of propagation and cultivation, and the insects and plants in- 
jurious to the trees. This circular included inquiries concerning the 
destructive locusts and concerning the direction of the winds. It was 
submitted to the Minister of Agriculture for his approval, and he cheer- 
fully indorsed it, and urged those who might receive it to give it their 
careful attention. Five hundred copies of this circular were printed and 
sent out through the empire, more especially through those parts of the 
country where cotton is or has been grown most extensively. The 
presidents of the provinces of Pernambuco and Maranhao aided me in 
directing these circulars to planters and other persons who were able to 
give me intelligent and trustworthy answers. 
During my stay in Rio de Janeiro I got together all the information 
and special reports to be had in the Portuguese language upon ento- 
mology. These consisted of a few valuable articles by Fritz Miiller, pub- 
lished in the Archivos of the National Museum, and a few miscellaneous 
contributions to be found scattered through old periodicals in the National 
Library. These latter articles, however, are rather curious than valuable, 
and could only be had by copying from the books. Through the kindness 
of Mr. W.T. Gepp I obtained access to the reports and statistics of Brazil- 
ian commerce kept by the Commercial Association in Rio de Janeiro, and
