This Bulletin consists of descriptions of some of the new species 

 of Fulgoroidea in the collection of the Hawaiian Sugar Planters' 

 Experiment Station, collected by Mr. Koebele and myself during 

 our investigations abroad. 



The first part is from manuscript notes left by the late Mr. G. 

 W. Kirkaldy. The delay in publishing these descriptions is to 

 be regretted, as some of the names may now be synonyms, but 

 the illness and sudden death of Mr. F. W. Terry, who had the 

 disposing of the library and papers of his former friend and col- 

 league, has been the cause of the delay, and now the doubly sad 

 task falls to me. I publish Kirkaldy's notes as he left them, un- 

 corrected, as my present knowledge of some of the families he 

 deals with is not sufficient to allow me to correct his work. 



The second part is by myself, with a few of Kirkaldy's descrip- 

 tions incorporated. It deals only with the famil}' Derbidae.
