INTRODUCTION. 
tain a quite full account of it, especially of its different food-plants 
other than cotton ; of its habits, characters, natural history, and natural 
enemies. A summary of its distinguishing points as compared with 
Aletia $ a full consideration of the different methods that are available 
to counteract its injuries, and a bibliography are also given. It is for- 
tunate that the best methods of underspraying the leaves of cotton 
with poisons to destroy the Aletia also prove, all things considered, the 
best means of preventing the injury to cotton of this Heliothis. 
Finally, in the Appendices will be found such reports from agents 
and observers as have been deemed worth publishing as supplementary 
to the report proper. The tabulated replies to the first circular issued 
from the department are not included, as they were published in the 
Department Cotton Insect Eeport^ while the more valuable of those in 
reply to Circular No. 7 are given in Appendix VII. As already stated, 
these Appendices include also Mr. Branner's report on observations 
made in Brazil, as well as the reports from consular agents upon the 
insect in other countries. 
The Notes, as already stated in the Preface, either contain matter of 
a technical nature that it was deemed advisable to exclude from the 
main text, or matter needed to still further elucidate or supplement it.
