Light chestnut, lighter over the carinae of pronotum and vertex;

 wliite bars on middle of face and a smaller one near base, none of

Female. Macropterous ; similar to male. Length 3.4 mm; tegmen 

 4 mm. 



The genitalia of this species are near to A^ dryopc and N. 

 munroi but they are quite distinct from both. Described from 

 nine males and twelve females from 29 miles, O'aa, Hawaii, 

 elevation 2300 feet, feeding on Antldcsma plafyplixllitiii, the 

 native name of which is haa {Giffard, Aug., 1918, Jan., 1919). 

 Also 9 males and 5 females from 23 miles, Olaa, Hawaii, on 

 the same food plant (Gififard, Aug.. Sept., 1919). These were 

 all taken in company of A'^. dr\opc.

Male. Brachypterous ; length 2.5 mm., tegmen 1.8 mm.; length 

 of vertex 1.3 times the width, apex wider than base, slightly rounded, 

 base about middle of eyes ; length of face twice the width, sides 

 slightly arcuate, median carina simple ; antennae reaching middle of 

 clypeus, second joint 1.8 times the length of first ; tegmina reaching 

 to apex of pygofer; hind femora reaching to end of abdomen, first 

 hind tarsus longer than the other two together. 



Opening of pygofer similar to 7. nigroceps (Muir), the anal spines 

 much smaller but diverging as in that species. The aedeagus has a
