Nysius vulean, F. B.-W. 
This is common at Kilauea, Hawaii, and specimens from 
this locality and considered (probably rightly) by Kirkaldy 
as identical with others from Lanai and Molokai, which he 
described as WV. montiwvagus, are clearly N. vulean. The 
actual type of WV. montivagus is from Lanai. 
N. pteridicola, ¥. B.-W. 
This distinct species is the one described as new by 
Kirkaldy under the name J. insulivagus. 
NV. coenosulus, St. 
Buchanan-White and Kirkaldy identified the same 
species under this name, but the latter had mixed there- 
with some quite different species, including NV. nemorivagus, 
F. B-W. 
NV. nemoriwagus, F. B.-W. 
This is a very distinct species, the dark antennae, the 
pale mottled tegmina and conspicuously black-spotted 
femora being evident superficial characters. The meta- 
pleura are very little emarginate in some examples, more 
so in others. It occurs at Kilauea, and was apparently 
considered a variety of NV. coenosulus by Kirkaldy. 
N. kamehameha, Kirk. 
This appears to me to be very close to the true J. 
delectus, F. B.-W. 
NV. ochriasis, Kirk. 
Usually found in the native composite plants, Railardia. 
NV. oribasus, Kirk. 
Probably a dark variety of the very variable NV. arbori- 
cola, F. B.-W. 
N. oresitrophus, Kirk. 
The unique type has evidently been placed in a damp 
jar for relaxation until the gum has spread over the whole 
surface. Until cleaned it is in no condition for being 
described. The description will probably be found 
incorrect.
