organizatiou, laying the foundation of what has developed 

 into an institution peculiarly serviceable and desirable for the 

 interchange of views, for important discussions, and for the 

 presentation of valuable entomological information, bearing on 

 local matters as well as matters of foreign import but related 

 to Hawaiian entomological interests, all of which has gradually 

 perfected a spirit of harmonious co-operation and co-ordination 

 along certain lines of systematic research and labor, which, 

 otherwise, might never have been possible. 



The Haw^aiian Entomological Society is not only to be con- 

 gratulated on the harmonious relations which have always 

 existed among the active members, but it is to be most heartily 

 congratulated because of the iuiportant and far-reaching results 

 which have been achieved by many of the men who have been 

 most actively engaged as members of this society. 



Working in their official capacities, members of this society 

 have, during the fifteen years of the organization, scored nu- 

 jnerous entomological achievements of far-reaching economic 

 importance. One of the ])rincipal reasons for so much entomo- 

 logical work having been undertaken may be found in the fact 

 that the ravages of the hopper on sugar cane, from 1902 to 

 1904, called for strenuous and continuous action. One might 

 say that the society owes its existence to the leaf-hopper. To 

 this cause, and the fear of further introductions of insect pests, 

 and the paramount necessity of inspection and the control of 

 all importations of plants and other vegetable matter, must also 

 be attributed the formal organization of the Board of Agri- 

 culture and Fortstrv and its various divisions, including that 

 of entomology. The excellent residts accomplished in the 

 work of controlling the cane leaf-hopj^T by the practical use 

 of its natural enemies are too well known by the members of 

 this society, and others, to reipiire any detailed review in an 

 address of this nature. The immense monetary saving to the 

 sugar plantations during 190r> and 100«), and in the years 

 following, has won the appi'eciative ackuowledgment of the
