HEMIPTERA 583 



(2) Nesopleias f dubautiae, sp. nov. 



Highly variable in colour, in some examples almost immaculate pale brownish 

 yellow ; in others, the tegmina and abdomen above are heavily blotched with blackish 

 brown. These colour variations are not sexual. Spur with nine spines. The pygophor 

 has a minute spine on the lip. The ^ styles are contiguous to the oedeagus at their 

 laterobasal angle and are produced ventralwards in a triangular lobe ; using the inner 

 side of this as a base, they are acuminately and obliquely triangular and are very 

 different to those of any other Hawaiian species. Length 3 mm. 



Hab. Oahu, Tantalus (1907, Perkins) ; Konahuanui, 2000 ft. (May, Dec, Swezey) 

 on Naenae {Dubautia pianiaginea).

This genus corresponds more or less with Delphacodes Fieber in the section with 

 non-compressed spur. The type is N. koae, but the genus as now comprehended is 

 doubtless heterogeneous.
