States engaged, or about to be engaged, in similar work. Mr. Busck's 

 report on a brief trip to Puerto Rico is in liue with other articles pre- 

 viously published. The trip was made at slight expense to the Divis- 

 ion, owing to the courtesy of the United States Commissioner of Fish 

 and Fisheries, and was practically a reconnaissance expedition to gain a 

 preliminary idea of the abundance of destructive insects on the island 

 and the probability of the entrance of new injurious species into the 

 United States through increased commercial relations with the island. 

 The insects collected on the trip have been named, but only the list of 

 scale insects is published at this time. 



Housekeepers will be interested in Mr. Tepper's Australian remedy 

 for cockroaches and Dr. Fisher's clothes-moth remedy, while the infor- 

 mation given about the recent spread of the Mediterranean flour moth 

 will interest those connected with milling industries.
