the base. The femora are more or less conspicuously spotted, but 
less so than in delectus, in which on the upper side of all the femora 
the black spots often unite to form a continuous line and the apices 
of the tibiae are much more black. 
This species varies much in size and in the colour of the head, 
In some examples there is only a narrow longitudinal median pale 
line on this part, in others the whole of the middle of the head in 
front is widely red. 
NV. delectulus is the Nysius 101 from Hawaii and 71 
from Maui of the Blackburnian collection. Specimens 
from Oahu are wrongly named J. coenosulus. 
Hab. All the islands from sea level to high elevations in 
the mountains. 
Nysius sublittoralis, sp. nov. 
Rufescent, dull, covered with whitish fine appressed pubescence, 
a longitudinal stripe along each side of the head, the region of the 
callosities, forming a band across the pronotum, one or more areas 
on the scutellum, black or dark-coloured ; clypeus white, or whitish. 
Tegmina with the widely explanate costal margins of the corium 
conspicuously white in fresh examples, all the rest of the corium 
and the clavus appearing comparatively sordid, in old examples 
yellow, a conspicuous dark longitudinal stripe down the middle of 
the corium and generally a dark line on each side of this, each about 
equidistant from it and subparallel, apical angle without a dark spot ; 
membrane white with two dark longitudinal stripes, and sometimes 
a third. Legs of an obscure reddish colour, the femora with only 
very inconspicuous darker dots, or without any. 
A very narrow, elongate species, the rostrum reaching only to the 
base of the hind coxae, the metapleura with the hind margin 
truncate or nearly so. Pronotum very long, the punctures rather 
fine and dense and much more even than in most of the other 
species. Head with only some fine punctures, not at all rugulose, 
but the sculpture is in fresh examples concealed beneath the 
tomentose clothing and that of the pronotum appears more sparse 
than is really the case. 
Length g 9, 4-5°5 mm. 
This species appears to resemble NV. longicollis more 
closely than any other species, but it is very distinct by 
the more widely explanate costal margins of the tegmina, 
the unspotted or faintly marked femora, ete. Blackburn 
took specimens on Maui (Vysiws No. 72). 
Hab. OAHU, Maui, on the lowlands; Hawaii in the 
higher fields of sugar cane.
