Orders of the Board of Agriculture of British Guiana, Georgetown,

 being injured by Brassolis sophorae. All leaves of palms which are 

 being or have been destroyed by this caterpillar are to be removed at

Ephestia kuehniella (the Mediterranean flour moth) , Plodia in- 

 ierpunctella (the Indian meal moth), Pyralis farinalis (the meal snout 

 moth), Sitotogra cerealella (the Angoumois grain moth), Calandra 

 granaria (the grain weevil), and c. oryzae (the rice weevil) are 

 collectively responsible in various parts of Canada for losses amount- 

 ing to many thousands of dollars. Recent experiments in the super- 

 heating method of control of these insects are described. The in- 

 stallation of additional radiation in warehouses necessary for this 

 method, can be made at a cost not exceeding the expense of one 

 fumigation with hydrocyanic acid gas, and the super-heating method 

 destroys such minute insects as Triholium confusum (the confused 

 flour beetle), which hides in places inaccessible to hydrocyanic acid 

 gas. In a large food store, which was badly infested with E. kuehniella, 

 the heating system consists of steam pipes, box stoves and steam 

 radiators distributed over the three floors. Steam was turned on
