ccii FAUNA HAWAIIENSIS 



species are really pretty insects. The nymphs are often abundant on the under side of 

 the leaves of the trees, in company with the adults. Unless disturbed by shaking, very 

 rarely are any of the latter seen on the wing. 



Koanoa, with one recognized species only, is almost universally distributed in the 

 forests of all the islands. It appears not so much to frequent leaves as the woody 

 parts of trees and is often taken on dead branches, when one is collecting beetles. 

 Kaniehanieha lunalilo, a species exhibiting some variability, is chiefly to be found in 

 damp forests, living on the mosses or creeping ferns, which clothe the trunks and 

 branches in such situations. Consequently it may be obtained from many kinds of 

 trees by indiscriminate beating of the branches. 



The Cyrtopeltis {C. hatvaiiensis) was obtained from a shrub or tree, not noted at 

 the time, but probably Dodonaea, at a high elevation, 8000 ft. or more, on Haleakala. 

 An apparently allied form is very common in the mountains round Honolulu, living, in 

 all stages, beneath the leaves of Gonldia. 



The small flightless Nesidiorchestes, in which the wings are absent, is terrestrial, 

 living chiefly in damp shady places, where the soil is more or less covered with decaying 

 leaves. Sometimes it is seen in numbers in company with the flightless Nitidulid 

 beetle, Apctinns cxplanatiis, and the flightless Dolichopodid fly, Eniperoptera, and 

 young of the flightless crickets iyParatrigonidiuni), which it slightly resembles in 

 appearance. 



Pseudoclerada moral is a remarkable insect, exhibiting conspicuous variation. 

 Some of these varieties, however, may prove to be closely allied species. There is 

 great sexual difference in the development of the eyes, and brachypterous forms occur. 

 The species inhabits damp shady places in the forest and has been found beneath bark 

 of dead branches of trees, and also amongst the moss or creeping ferns growing on 

 these. Like Mdrarga, they hide at the bases of the leaves of Freycinetia, where 

 rubbish accumulates. They may possibly prove to be predaceous. 



In the genus Sarona there are a number of forms, the extremes differing greatly 

 in size and colour, but apparently showing little or no distinction in superficial structure. 

 In most localities on Oahu they are rare, but in parts of Hawaii occur in great 

 numbers, frequenting the leaves of various forest trees. On one occasion I examined 

 a large number of specimens from Mefrosidenis, and found great variability in size and 

 colour, while close by on a species of Raillardia were many specimens, small, black, 

 and hardly at all variable either in size or in colour. On Oahu, near Honolulu, they 

 are to be found on Pclea, and I think these Oahuan specimens do not vary much, nor 

 do they visit the trees of Metrosidcriis, in the neighbourhood of the Pelea. Unless 

 new characters for specific distinction are discovered, the number of species that exist 

 will, I expect, remain very uncertain. The largely developed hooks of the male 

 genitalia may prove of use for distinguishing the species. 



Kalania hawaiiensis is allied to the preceding and resembles it in habits, and in
