586 FAUNA HAWAIIENSIS 



(6) Nesosydne gouldiae, sp. nov. 



Brownish white ; frons and ciypeus between the keels, dark fuscous ; pronotum 

 and scutellum between the keels, genae, etc., more or less fuscous. Tegmina yellowish 

 brown, hyaline, veins more or less fuscous, the apical ones yellowish brown, apex of 

 clavus and of subcostal dark fuscous. Legs and sterna pale yellowish. Tergites more 

 or less variegated with dark fuscous. Second segment of antennae one-third longer 

 than the first. Tegmina with the clavus not completely sutured off; three apical cells, 

 subcostal cell apically acute. Spur with lo — 1 1 spines. Tegmina not reaching to the 

 apex of the abdomen. Length 4 — 5 mm. 



The nymphs of the last instar have the same general colour as the adult, but the 

 tergites are fuscous except a narrow longitudinal row of spots down the middle (making 

 a broken line), and two sublateral longitudinal brownish yellow stripes on two or three 

 segments. There are also some pale specks, etc. Second antennal segment about 

 twice as long as the first, fore and middle tarsi unjointed, hind tarsi trisegmentate, the 

 spur with 7 — 8 spines.

Nesosydne ipomoeicola Kirkaldy, 1908, op. cit. 202, PL 4, fig. 4. 



Somewhat like A'", kalia, but the pronotal keels are more divergent and curving, 

 and do not reach the hind margin ; the brachial and radial veins are forked near the 

 subapical line ; there are five apical cells and the tegmina are a little longer. The frons 

 is nearly parallel-sided, very slightly (and gradually) narrower basally than apically. 

 Antennae shorter, scarcely reaching beyond the base of the ciypeus. Basal margin of 

 tegmina fuscous. 



^. Head, pronotum and scutellum dark fuscous, or blackish, keels of head pale. 

 Sterna, abdomen more or less, etc., dark fuscous or blackish. 



$. Similar to the same sex in N. kalia, but the abdomen is more obscure.
