HEMIPTERA

(7) Nysins kylaetis, sp. nov. 



Pale yellowish testaceous, glabrous. Vertex with some dark markings, principally 

 longitudinal, which vary in situation and depth of colour, in the three specimens before 

 me. Second and third (except extreme apex), a spot on fourth, and the whole of the 

 fourth segment of antennae, blackish brown (in one example, second and third paler). 

 Eyes red-brown. Ocelli red. Pronotum with a short, oblique, subpyriform, laevigate, 

 black spot on each side of the middle, not nearly reaching the lateral margins of the 

 pronotum. Pronotum closely punctured, punctures mostly nearly colourless, except on 

 and near the apical margin. Postero-lateral angle in some examples dark, also the 

 hind margin is soiled in some. Scutellum similarly punctured, a blackish spot on the 

 anterior half in the middle. Sterna dark brown, polished ; pleura closely punctured, 

 a little darkly suffused in part ; hind margin of metapleura pale, not punctured. 

 Tegmina rather feebly mottled with brownish grey, apical margin of corium in some 

 examples more darkly so, apical angle in some blackish brown. Membrane hyaline, 

 mottled with brown. Femora with a subapical dark brown ring, tinged with rose 

 apical of this. Abdominal sternites tinged with rose, a sublateral black blotch on basal 

 half (this is somewhat variable). Antennae with the first segment extending just 

 beyond apex of vertex, second slightly longer than the third, and slightly shorter than 

 the clavate fourth. Labium reaching to metasternum. Pronotum with the lateral 

 margins very slightly sinuate, not much wider basally than apically, toothed minutely 

 at the antero-lateral angle. $ not remarkable. $ 5th sternite apically obtusangulate, 

 6th acutangulate. Length 45 mm. 



Hab. Kauai, high plateau (Aug., Perkins), Waimea Mts., 4000 ft. (May, Perkins). 



This species is easily recognized among the pale glabrous forms by the short, 

 pyriform, laevigate areas on the pronotum. 



Nysius kantehameha Kirkaldy. 



Nysiiis kamehameha Kirkaldy, huj. op. iii. p. 164. 



Hab. Hawaii, Hualalai, 5000 ft. (Aug., Perkins). 



I have seen no specimens beyond the carded type of this, for a Nysius, handsome 

 species. The labium extends practically as far as the hind coxae. The tegmina are 

 parallel for about one-seventh of their length, thence gently rounded. The exterior 

 half of the metapleura black, the hind margin and the interior half, together with the 

 orifice, pale.
