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

 who were botanizing and collecting seeds from our indigenons 

 forest trees for the Golden Gate Park in San Francisco. Onr 

 stay of one and one-half days at Pnnwaawaa 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 Coleoptera as could be incidentally ca])- 

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

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

 riding and by the time the interesting forest region is reached 

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

 due to Idosc scoria it is most difficult walking and collecting 

 amongst the sparse vegetation. Much of the latter, including 

 the lower foliage of the trees, has been destroyed of late years 

 In- cattle and very many of the trees themselves destroyed by 

 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) I endeav- 

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

 yet been recorded from this particular region in the district of 

 Xortli Kona. As a result only one new species (Nesosjjdne 

 phyllostegiae) was collected, but several new food plants of cer- 

 tain known species of Delphacids were found which in itself 

 was well worth the trip. These latter and the fact that a series 

 of Alalia sii'czci/i 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, 1 believe this to be the third 

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



Before returning to Hilo from Kilauca a portion of the 

 ''inside" forests located at 29 Miles (so-called) about two miles 

 north of the Volcano House, were visited for a few hours l)ut 

 nothing of any special importance not already published M'as
