22. N. ralUardiae Kirk. 



Antennae very short, first segment less than half the length of 

 second; aedeagus very short, flattened, deep at base, a small row of 

 spines on ventral side near apex, another on dorsal slightly on right 

 side, none on left side.

23. N. ipomoelcohi Kirk. 



Antennae reaching beyond middle of clypeus, first segment more 

 than half the length of second. Aedeagus tubular, flattened on dorsal 

 surface at apex, a stout spine on each side of the flattened area; 

 anal spines short, stout, wide apart and pointing backward. 



Kirkaldv's figure of the styles in this species is not very 

 clear. This species is widely distribnted in the archipelago 

 and appears to have several distinct subspecies or varieties 

 which only more material vill fnlly elucidate. In one form 

 there are three s])ines around the apex on the ventral side 

 (Kilauea, Hawaii, Giflfard and Muir, January) ; in another 

 very distinct form the flattened surface is practically absent 

 and the two large spines are quite close to the apex (Kilauea, 

 Hawaii, Gift'ard and Muir, January). This last variety is 

 distinct enough to be given a specific name.

24. N. licdia Kirk. 



Antennae reaching nearly to apex of clypeus, first segment more 

 than half the length of second. The aedeagus appears to be an ex- 

 treme development of ipomoeicola, the dorsal, flattened portion be- 

 coming membranous; on the right edge of this membranous sur- 

 face there are three spines, the basal one large and bifurcate, the 

 left having only one feebly furcate spine.

25. N. giffardi sp. n. 



^ Frontal carina forking a little beyond middle; antennae reach- 

 ing nearly to middle of clypeus, first joint more than half the length 

 of the second; tegmina reaching about middle of abdomen. Brown, 

 face and clypeus darker between carinae; posterior edge of abdo- 

 minal segments darker. Tegmina light brown, a small dark mark 

 at apex of clavus, veins concolorous as membrane, very minute gran- 

 ules with black hairs. No spines on anal segment, ventral edge 

 lipped; styles long and narrow; aedeagus large, laterally flattened, 

 base very deep, apex deep, two spines on dorsal surface about middle
