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 the same 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 find 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 Bio 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 countrj 7 , the kinds 

 planted, the methods of workiug 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, aud 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 Bio 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 obtai ued access to the reports and statistics of Brazil- 

 ian commerce kept by the Commercial Association in Bio de Janeiro, and
