yellow. Tegmina hyaline, faintly brown, a dark brown mark at 

 apex of clavus and a very faint one at end of costal cell; margins 

 of tegmina, except at end of clavus, light yellow, veins concolorous 

 as membrane, apical veins slightly lighter, no granulations. 



The aedeagus is bent much more than in the preceding species, 

 a ring of spines toward apex, formed of some eight or nine spines 

 on right side and four on left side. 



Length 2.6 mm.; tegmen 1.8 mm. 

 Hab. Haleakala, Maui, 5000 feet elevation. 

 From one male specimen (No. 636) of Dr. R. C. L. Per-

14. N. wailupensis sp. n. 



$ Brachypterous, tegmina not reaching quite to end of abdo- 

 men. Antennae reaching to near apex of clypeus, first joint consid- 

 erably more than half the length of second, furcation of frontal 

 carina about a third from base. Head fuscous or black between 

 carinae, antennae and carinae light brown or yellowish, thorax 

 brown or fuscous brown with light carinae, legs fuscous brown, front 

 tibiae with darker band at apex; abdomen dark brown, light at base 

 and a small line down dorsum. Tegmina light brown, margins 

 whitish, except at apex of costal cell and apex of clavus where it is 

 brown, this brown extending into membrane; veins fuscous except 

 apical veins which are light, no granules, a few black hairs along 

 apical margin and a few on nerves. 



Pygophor very distinct, lateral edges angular, anal segment with 

 large stout spines, wide apart and slightly diverging, ventro-apical 

 edge lipped; styles long and narrow; aedeagus tubular, slightly 

 curved, a small group of spines on ventro-apical point and a few 

 on left side near apex, four or five along middle on dorsal side, four 

 or five in a corresponding ventral position and a few along the right 

 side. 



Length 3.3 mm. ; tegmen 2.3 min. 

 2 Brachypterous, tegmina not quite reaching apex of abdomen. 



Length 3.7 mm. ; tegmen 2.5 mm. 



Hab. Wailupe, Oahn (Swezey, January). Some speci- 

 mens (immature?) are nearly all yello\yish, the tegmina with 

 only the dark mark at apex of clavus and apex of costal cell.

15. N. pipturi Kirk. 



Anal spines long, thin, pointed, nearly straight, slightly diverg- 

 ing apically; aedeagus small, tubular, slightly curved and pointed 

 apically. There appears to be some variation in the spines on aedea- 

 gus; in some they are absent, in others irregular around middle or 

 arranged in more or less of a line. These variations appear to follow
