SOME NEW OAHUAN (HAWAIIAN) HBMIPTERA. 177 



three lateral longitudinal silvery stripes, the median of these three not 

 nearly reaching the base. Ovipositor in the female pale brownish. 

 Tibial spur with eight c-trong spinelets. Long. 2^ mill. 



Oabu : Leahi. On a yellow composite not yet determined. 

 (Only inside the crater, or on top, not on the lower slopes. 

 March-April, 1904— G. W. K.). 



The above is the colouring in living examples ; when dry the 

 green often turns to pale yellow, and the whole colouring becomes 

 more obscure. 



Aloha/^'- gen. nov. 



Belongs to the division with short antennae, and straight 

 entire pronotal keels. 



Head narrower than the pronotum (lateral margins between the 

 eyes subparallel), little prominent before the eyes, as seen from above, 

 anterior margin roundly truncate ; vertex shaped something like 

 Delphacodes, Fieb.f (nee Melichar), but the middle keel generally 

 almost obsolete (sometimes, however, strongly developed), with an im- 

 pressed spot on each side. First segment of antennse about two-thirds 

 of the length of the second. Frons somewhat narrow, subparallel, 

 with two median keels which are subparallel, but slightly rounded out- 

 wardly, obsolete on the arched part of the head. Clypeus tricarmate, 

 median keel strongly developed. Eostrum reaching to posterior coxte. 

 Pronotum short, keels entire. First segment of posterior tarsi about 

 twice as long as the other two together, tibial spur about two-thirds 

 the length of the first segment of tarsi. Tegminal venation very 

 similar to that of Megamelus. 



Aloha ipomoe^, sp. n. 



? . Flavo-tesfcaceous above and beneath, exterior lateral margins 

 spotted with blackish brown. Tegmina hyaline tinged with brownish, 

 immaculate in the long-winged form, except that the apical angle of 

 the lower claval area is dark brown ; in the short-winged form there 

 is a spot at the apex of the costal area ; veins with setigerous blackish 

 granulations. 



(?. Similar to the female, but darker; abdomen blackish, apical 

 margin (and lateral margins more or less) pale ochreous or flavous. 

 Tegmina spotted with black. Long. 2h-6 mill. ; expanse of tegmina, 

 8 mill. 



Hah. Honolulu, from coast-line up to about 1000 ft. ; on 

 various species of Ipomoea (R. C. L. Perkins and G. W. K. ; 

 March, April, 1904). This species is doubtless autochthonous. 



Deltocephalus iiospes, sp. n. 

 In structure somewhat near to D. signatifrons, Van Duzee, 

 but with different head pattern, &c. 



* "Aloha," the Hawaiian salutation (lit. "love"). 



f The type of Delphacodeis, Fieb., is muhanti, Fieb. For Melichar's 

 genus Deljphacodes I propose the uauie Pscu(l((r(eo2}iis,typc lethierryi (Rey).
