Type Iwae. 



1. N. I'oae Kirk. 



This species is at present known from Oahu and Ilaw^aii ; 

 female specimens from Waimea, Kauai (Swezey, February) 

 mav be the same, but the fact that the species attached to the 

 phyllodia of koa in that island is distinct from that on Oahu 

 or Hawaii makes it probable that the green species is also 

 distinct. 



Both the nvmphs and adults are of the same bright green 

 as the young leaves of Acacia koa on which they feed ; a few 

 stra}^ specimens are occasionally taken from the phyllodia. 



The type locality of this species is Tantalus. In specimens from 

 this locality the anal spines are fairly long and slender, the aedeagus 

 slightly compressed, slightly curved in profile esnecially along the 

 ventral edge and towards the base, being broadest in the middle; 

 a row of strong spines curves from an apical-dorsal point across the 

 right side to a ventro-basal point, on the left side a less well defined 

 row of spines runs from apex to near base near to the ventral edge. 



Specimens from Kilauea, Hawaii, are characterized by being 

 darker, especially on the mesonotum; the aedeagus is not so greatly 

 curved on the ventral edge and the anal spines are shorter and 

 thicker. 



Fig. 32. This figure is not so broad in the middle or so 

 strongly curved on ventral edge as it should be. 



2. N. ruhescens Kirk.

This I consider to be a distinct species from koae and treat it 

 accordingly. It is attached to the phyllodia of Acacia koa and is 

 colored in accordance with its habitat both in the nymphal and aduu 

 stages; a few stray specimens are occasionally found on the young 

 leaves. 



The type locality is Tantalus, Oahu, where the average color is 

 a light reddish brown with lighter carinae. The anal spines long 

 and thin; aedeagus straight to near base, the apical opening on the 

 right side, a dorsal row of strong spines runs from apex to near
