LETTER OF TRANSMITTAL. 



To the Experiment Station Committee of the Hawaiian Sugar 

 Planters' Association, Honolulu, T. H. 



Gentlemen : — I, herewith, submit for publication Bulletin IV 

 of the Division of Entomology. This is based almost entirely on 

 the parasites and leaf-hoppers recently collected and studied by 

 Mr. Koebele in Arizona. It has been prepared by Mr. Kirkaldy 

 and myself. 



Yours obediently, 



R. C. L. PERKINS, 

 Director, Division of Entomology.
