(lata as to the insects of this ahiiost continuoush' wet region 

 might have been gathered had it been possible for me to remain 

 at Kilanea for a sufficient length of time. As it was I was able 

 to visit and collect at these latter places for a few honrs on two 

 separate days with satisfactory results. Besides the discovery 

 of one new species of Delphacid (Ncsosydne cyrtandricola) the 

 hitherto unknown food plant of the single male i\". anreps 

 taken by Muir in 1915 was found to be Frcycinctla aniottl 

 (ieie vine). A good series of both sexes of the last named Del- 

 phacid was taken. Undoubtedly the absence of moisture over- 

 head and on foot in the boggy forests of this region would have 

 produced much better collecting had I been able to stay over 

 another week, as insects in general were more plentiful there at 

 the time than 1 had ever found them on previous visits, which 

 were always attended by more or less precipitation and conse- 

 (juent inability to properly collect. 



I am indebted to my friends Messrs. Muir and Kock for 

 assistance, by the former in the determination of the Delpha- 

 cids collected and by the latter of the food plants. 



Following are the detailed field notes* covering certain 

 of the species taken during the visits referred to, viz. : 



Leialoha Jehuae hairaiiensis Muir, Olaa 20 miles (Xos. 7 

 and 30. Long series males and females off Mctrosideros poly- 

 moi'pha var. Incana (Ohia lehua). Also reared a number of 

 adults from nymphs on the leaves of this food plant. One male 

 (Xo. 44) Olaa 25 miles, 3000 ft. elev., off Platydesma sp. 

 Probably this was an accidental capture although no ohia was 

 growing in this particular section of forest. 



Nesodryas dry ope Kirk. Glenwood 22 miles, 2300 ft. elev. 

 (Xos. 26, 34 and 38) 12 males and 3 females off A)ifides)na 

 platyphyUiun. 



Nesodryas maculata Muir. Kapua, South Kona, 2000 ft.
