Ilab. Oahu, Pimalim (Swezey, June, 1911). This species 

 is very distinct, the aedeagus not being closely related to any 

 of the described species. Along with N. palustris it shares the 

 distinction of having the ventral edge of the pygophor produced 

 into a large spine. 



N. l-oehelcl sp. nov. PL V, figs. 10, 10a. 



^ Brachypterous, tegmina reaching to base of pygophor; anten- 

 nae reaching beyond middle of clypeus, first segment nearly equal to 

 second in length; frontal carina simple. 



Stramineous, fuscous between carinae of head and thorax, and 

 over the sides of abdominal tergites. Tegmina stramineous, veins 

 slightly fuscous, a dark mark at apex of clavus and another at apex 

 of costal cell. 



Pygophor wider than deep; anal segment with two short, broad 

 spines, their bases approximate and apices diverging; genital styles 

 broad at base, curved, narrow on apical third, the apices curved and 

 truncate; aedeagus short, flattened laterally, apex subcrassate and 

 bent to the left. 



Length 3.6 mm.; tegmen 2 mm. 



Hab. Oahu, Punaluu (Swezey, June, 1911). This species 

 is very distinct, but I place it in the vicinity of N. sharpi. 

 I name it after IMr. A. Koebele, whose associations with en- 

 tomological work of our island is well known to local entomolo- 

 gists. 



N. hJackhurni ]\[uir. 



One male taken at Punaluu, Oahu, by Swezey (June, 

 1911). Previously known only from Hawaii. 



N. iicphelias Kirk. PL V, fig. 8. 



One male specimen from Lanai, Ilalelepaakai (Perkins. 

 I^o. 134, July, 1894), which differs from the description by 

 having the carinae of the same color as the rest of the head 

 and thorax, the femora not striped and the two fuscous marks 

 on tegmina more extensive. The genitalia come near to those 

 of iV. anceps and N. sivezeyl. 



N. nif/rireps sp. nov. PL VI, figs. 33, 33a. 



$ Brachypterous; vertex longer than wide, slightly rounded at 

 apex; antennae reaching beyond middle of clypeus, first joint to 

 second as 1 to 1.7; lateral pronotal carinae straight, diverging poste- 

 riorly, reaching hind margin; frontal carina forking near base.
