Hawatian Hemiptera. 735 
N. monticola, Kirk. 
I have a specimen. of the other sex from Haleakala, 
Maui. The rostrum appears rather shorter, but it is 
clearly the same species. 
N. nubicola, Kirk. 
The rostrum reaches behind the hind coxae in this 
species, and far behind the coxae in JN. pteridicola. LN. 
nubicola is the No. 120 of the Blackburnian collection, 
but was never described. 
NV. hylaeus, Kirk. 
Described from Kauai, occurs also as a variety with the 
dark markings less developed on Oahu. 
Nysius haleakalae, sp. nov. 
Glabrous, smooth and shining, the rostrum shortish (if laid back 
probably reaching about to the hind coxae), hind margin of meta- 
pleura hardly concave, the upper angle almost a rectangle. Allied 
to Nysius whitei. Colour brownish-yellow, the head especially and 
part of the corium suffused with red. Hind lobe of the pronotum, 
except the hind margin, and much of the clavus and corium dark 
brown or infuscate; membrane with median conspicuous dark 
longitudinal band of infuscation. Front and middle legs wholly 
pale, yellow; the hind femora dark on more than the apical half, 
excepting the pale apex itself, their base as well as the tibiae and 
tarsi pale. Antennae yellow, asmall spot at the base of the 2nd and 
3rd joints dark. Head very smooth and shining, without rugulosity. 
Pronotum with a transverse row of punctures behind the front 
margin, another row behind the callosities, behind this very sparsely 
and subobsoletely punctate; scutellum pale, with dark punctures 
along each side. Tegmina smooth and shining. Abdomen beneath 
black, except the red apex and lateral margins. 
¢. Length 4°5 mm. 
Distinguished from JV. whitei by the more widely banded 
hind femora, less emarginate metapleura, smoother head, 
etc. 
Hab. Mauvt, Haleakala, below 2,000 ft. 
Nysvus hiloensis, sp. nov. 
Flavescent, shining, the head black ; the head and pronotum with 
very delicate pubescence, hardly noticeable except on the black
