The nu)S(|iiit() <iiu'sti<)n is ji serious one in IIa\v:iii. NO {ittcmpt liiis 

 Ih'cm niiule to destroy tiiein, simply protection from the adult l)ei!i^»- 

 practiced. The introduction of the insect into Hawaii, its distriljution 

 and ahundanco in the Teiritor\ , lias be(M» worked out. Determina- 

 tions made ])v Mr. Coquillett, of the I)i\ision of Kiitomoloj^y, l^. S. 

 Department of Agriculture, gives, besides the common mos!iuito(6W(?a:' 

 ptpie?is), two ypecies of the dangerous yellow-fever genus Stcgomyia, 

 the CuIkui yellow-fever species {^Ste<j<yiiiyhi fnxciata and aS\ Heutellarix). 

 The entomologist has given several lectures illustrated l)v lantern 

 slides on the life history and l^rceding places of moscpiitoes and the 

 methods used elsewhere to (h'stroy them. He is taking a leading part 

 in the campaign recently started luider the direction of the hoard of 

 health anci department of public works to lessen the num})er of this 

 pest in Honolulu and has in prei)aration a bulletin on the mosipiitoes 

 of Hawaii, the result of Ineeding experiments in the laborator}', and 

 observations in the field. 



This department has rapidly outgrown the small space allotted to it 

 at the beginning of the 3'ear. For the coming year's work an insectarj'^ 

 in which to carrj on breeding experiments and to observe more accu- 

 rateh' the metamorphosis of certain species is in course of construc- 

 tion, and moi'e la])oratory room with additional (Miuipment will be 

 given. 



Acknowledgments are given to Dr. L. O. Howard, Entomologist of 

 this Department, for determinations made of specimens sent to him 

 during the .vear^ and to Prof. V. L. Kellogg, of Stanford Universit}^, 

 for many \alual)lc suggestions made b}^ him in organizing the depart- 

 ment while visiting the islands one year ago.
