HEMIPTERA 587 



Vars. Both sexes vary more or less in the following directions, head often scarcely 

 fuscate. Apex of commissural and of subcostal cells, etc. dark fuscous ; these may 

 meet and be extended in a large median black blotch in the $. Abdomen often orange 

 red, more or less marked with black. Length ,? 2-J; ? 3^ — 3-| mm. 



Hab. Kauai, 400 ft. (Oct., Giffard) ; Oahu, Honolulu (Stal), Tantalus, 1300 ft. 

 (Kirkaldy, Giffard, Perkins, Swezey, Terry), on Ipomoea bonanox, etc. ; Honolulu and 

 Kalihi, sea-level to 50ft., on Jussiaea villosa (June, Swezey); Makiki, 150ft., on 

 Dolichos lablab (March, Swezey). Hawaii, above Hilo, 1800 ft. (Dec, Perkins, two tt), 

 Olaa (Nov., Perkins, one $). 



This is perhaps the commonest endemic Asiracid. I have not seen Stal's type, 

 but I have no doubt of the correctness of the identification ; the name given by him, 

 however, is preoccupied. 



Macropterous form. Head with keels brownish yellow, the intracarinal spaces more 

 or less fuscous. Nota brownish yellow, more or less strongly and entirely suffused /^ 

 with dark fuscous, the keels usually excepted. Tergites mostly blackish brown. 

 Tegmina hyaline, veins pale testaceous, basal margin and a mark on the commissure 

 blackish, apical veins (at least apically) and apical margin, also veins of wings, fuscous. 

 Length 4 mm. 



(9) Nesosydne haniadryas, sp. nov. 



%. Shining dark fuscous ; keels of frons and clypeus narrowly margined with 

 fuscous. Antennae, labium and legs, pale yellowish white. Scutellum piceous. Teg- 

 mina hyaline iridescent, appearing blackish basally, owing to the abdomen showing 

 through, veins fuscous. Head dorsally scarcely longer than broad, extending very little 

 beyond the eyes ; lateral margins of frons subparallel. Antennae reaching well beyond 

 the base of the clypeus, second segment one-half longer than the first. Tegmina reach- 

 ing well beyond the abdomen, with six apical veins, second and third with a common 

 base, and the third forked near its base. Pronotum with the lateral keels not reaching 

 the hind margin but also not curving away. Spur with 10 spines. Length % 4^ mm. 



Hab. Oahu, Tantalus (i ?, Perkins, 1906). 



I am indebted to Dr Perkins for the loan of this, the only specimen he has taken. 



(10) Nesosydne haleakala, sp. nov. 



$. Brownish yellow ; genae, clypeus and apical part of frontal keel blackish brown. 



Teo-mina with a fuscous stripe obliquely from the base (exteriorly) to apex of clavus, 



darkening at the two ends. Tarsi blackish. Tegmina scarcely reaching beyond the
