582 FAUNA HAWAIIENSIS 



pale yellowish. Antennae yellowish. Tegmina subhyaline pale yellow, veins yellowish 

 white, sparsely granulate with brown ; middle two-thirds of tegmen from subcosta to 

 suture, smoky. Tergites yellowish, sutures blackish, lateral margins variegated with 

 black, sternites mostly blackish. Labium reaching to hind coxae ; second segment of 

 antennae scarcely twice as long as the first, the second being about as long as the 

 median width of the frons. Tegmina micropterous, extending about as far as the apex 

 of the abdomen, with 5 — 6 apical cells. Spur with eight spines. 



?. Usually much paler than the male, the vertex, pronotum, and scutellum being 

 more or less pallidly suffused, but sometimes these approach the coloration of the male. 

 Tergites dark with yellowish markings apically. Length 4 mm. 



Hab. Hawaii, Kilauea, 4000 ft. (July — Sept., nos. 578, 656, 686 & 691, Perkins, 

 July, Giffard, Dec, April — May, Kirkaldy) on Myoporum sandwicense ; Kona, 4000 — 

 5000 ft. (June — July, Perkins). 



The type is a Kilauean example. 



Nesopleias, gen. nov. 



This genus has very much the appearance of Nesorestias, but the tegmina are not 

 reticulate, and the frons has two entire keels. From Aloha, etc. it differs by the form 

 of the tegmina, and by the elongate frons, which has two fine, very distinct, subparallel 

 keels, which enclose a sublinear space throughout, meeting just basal of the truncate 

 apical margin. The genal carina meets the frontal keels acutely. Pronotum with three 

 straight keels, the lateral ones meeting archedly in front ; all meeting the hind margin 

 straightly. Scutellum tricarinate. 



Conspectus specierum hawaiiensiuni. 



I. Tegmina cellulis apicalibus destituta ; margine postica densata i ntmbata nov. 



I a. Tegmina cellulis apicalibus instructa ; margine postica ordinaria 2 dubautiae nov. 



(i) Nesopleias ttinibata, sp. nov. 



%. Pale brownish yellow, paler beneath, the tegmina with a fuscous band just 

 exterior to the clavus and crossing it at the apex, where it darkens and thickens ; basal 

 of this band the colour is paler. Tergites blackish brown laterally. Tegmina scarcely 

 reaching beyond the middle of the hopper, roundedly arched externally, rounded 

 apically. Subcostal cell and apical margin strongly thickened, especially the latter, 

 which is not venose. Radial and brachial veins forked obscurely immediately basal of 

 the apical margin. Length 3 mm. 



Hab. Oahu, Tantalus, 1500 ft. (Feb., 1907, Perkins). I have seen only a single 

 female of this curious form.
