Prof. J. F. Rock of Honolulu and A. Holm of San Francisco, 

 who were botanizing and collecting- seeds from our indigenous 

 forest trees for the Goklen Gate Park in San Francisco. Our 

 stay of one and one-half days at Puuwaawaa was quite too 

 brief for systematic collecting of the insect fauna of that 

 interesting region and I therefore utilized the few hours at my 

 disposal searching for Delphacids and other Homoptera and 

 such Heteroptera and Goleoptera as could be incidentally cap- 

 tured. The rough nature of this region, covered as it is with 

 old lava floAvs of the a-a type, makes very slow walking or 

 riding and by the time the interesting forest region is reached 

 much of the day has been wasted getting there, and even then 

 due to loose scoria it is most difficult walking and collecting 

 amongst the sparse vegetation. Much of the latter, including 

 the lower foliage of the trees, has l^een destroyed of late years 

 by cattle and very many of the trees themselves destroyed liy 

 continuous drought and from other causes. A full week or ten 

 days insect collecting in these forests would undoubtedly pro- 

 duce very satisfactory results but due to the limited time at 

 my disposal (five hours in all of actual collecting) T endeav- 

 ored to confine myself to the Delphacids none of which had as 

 yet been recorded from this particular region in the district of 

 IsTorth Kona. As a result only one new species (Nesosydne 

 phyUoster/iae) was collected, but several new food plants of cer- 

 tain known species of Delphacids were found which in itself 

 was well worth the tri]). These latter and the fact that a series 

 of Alolia sirezeyt was captured for the first time on any other 

 island than Oahu, will be referred to in detail in the accom- 

 panying field notes. Incidentally, I believe this to be the third 

 species of the Genus Alolia taken on the Island of Hawaii. 



Before returning to Ililo from Kilauca a portion of the 

 "inside'" forests located at 21) j\lih\s (so-called) about two miles 

 north of the Volcano House, were visited for a few hours but 

 nothing of any special importance not already ])ul)lished Avas 

 captured. Due to a protracted drought in the neighborhood of 

 Glenwood and "25 ^Nliles" (so-called) Olaa, much interesting
