8 BULLETIN NO. 4, DIVISION OF ENTOMOLOGY. 



Mr. Branner's report is preliminary to a more extended one, but gives 

 a definite idea of what work was accomplished during the Brazilian trip, 

 and, with the statement of his instructions, will indicate the objects of 

 the trip and the important beariug of the information on the work of 

 the Division. 



Mr. Voyle, in his report, gives the results of experiments by which he 

 has determined the amount of cold which Scale-insects can bear, thus 

 settling a point which has long been in dispute among orange-growers.
