and a series of large spines around the rim of the dorsal portion of 

 apex.

5 One specimen which agrees in structure and color I place 

 with this male. 



Length 3 mm. ; tegmina 1.15 nun. 



Hab. Tantalus, Oahu (Giffard, March) ; 9 Pacific Heights, 

 Oahn (Swezey, March). 



PL 3, fig. 54; PI. 4, fig. 74. 



26. N. niontis-tanfalus sp. n. 



^ Frontal carina forking at extreme base; antennae reaching 

 to middle of clypeus, first joint considerably more than half the 

 length of second; tegmina reaching about one-fourth from end of 

 abdomen. Light brown, fuscous between carinae on face and clypeus, 

 abdomen dark brown, base, median line and some medio-lateral spots 

 on dorsum lighter. Tegmina light brown, with a darker mark from 

 base of costa to apex of clavus a small dark mark at apex of costal 

 cell, veins concolorous as membrane with a few fine black hairs. 

 Shape of pygophor much like that of giffardi; apex of anal segment 

 slightly emarginate, each corner produced into a short, broad, blunt 

 point; no anal spines; styles long, thin, tapering to a point; aedea- 

 gus on plan of giffardi with three spines on medio-dorsal position 

 and two on ventral side near base, two small spines at apex on 

 dorsal side and four on right side. 



Length 2.3 mm. ; tcgmen 1.5 mm. 



9 Similar to male, but lighter, the fuscous mark across tegmen 

 very faint. 



Length 2.5 mm. ; tegmen 1.4 mm.

27. N. sharpi sp. n. 



^ Brachypterous, tegmina reaching nearly to end of abdomen; 

 antennae reaching nearly to apex of clypeus, first joint considerably 

 longer than half the second; furcation of frontal carina at extreme 

 base. 



In coloration this species is very like u-ailiiijejisis : legs are a 

 little more fuscous, especially the hind tarsi. In shape the aedeagus 

 is near ivailupensis : the anal segment is truncate at apex with a 

 large curved spine from each corner; styles long, thin, with apices 

 truncate and slightly expanding; the aedeagus on a plan somewhat 

 like giffardi or halia, flattened laterally, the apex ventrally drawn 

 out into a long point, and dorsally on right side produced into a
