Hawatvian Hemiptera. 731 
posteriorly and tegmina green; clavus for the most part blackish, 
membrane smoky black, with a clear area adjoining and extending 
behind the cuneus. Second and following joints of the antennae 
dark, the second sometimes yellow except at the apex. Basal joint 
of antennae about three times as long as wide ; second about 1} the 
length of the third, fourth about ? as long as the latter. Eyes 
nearly similar in the sexes. Head, thorax and tegmina with pale 
pubescence. Bristles of the hind tibiae pale, the tarsi more or less 
dark. 
Length 2-2 to about 3 mm. 
dé with the right and left clasper very unlike, the one wide and 
blunt at the apex with a tuft or area of very long hairs towards the 
base, the other narrow and elongate, somewhat twisted, with a 
chitinous hook at the apex, preceded by a sharp angle ; hairs near 
the base much shorter than on the other clasper (Fig. B). 
This small and delicate species resembles some varieties 
T. kanakanus, but it is much smaller, very little variable 
and quite distinct structurally. Owing to the variability 
of some of the Hawaiian Tichorhinus the number of 
species is quite uncertain, and probably will remain so 
until the claspers and other male characters are thoroughly 
investigated. 
Hab. OAnU, one of the commonest insects on Mt. Tan- 
talus, near Honolulu, on the leaves of the Urticaceous 
tree Pipturus. It is also found in widely separated localities 
on the island. 
Tichorhinus kirkaldyt, sp. nov. 
Colour almost as in typical 7. kekele, Kirk., but much smaller and 
easily distinguished structurally by the short basal joint of the 
antennae, which is only about twice as long as wide. Tegmina seen 
from in front or from the side with black hairs and no appressed 
golden pubescence. Hairs of the head and pronotum and the 
bristles of the hind tibiae black. Membrane smoky, with a white 
spot adjoining the cuneus. Hind tibiae hardly four times as long 
as the tarsi. The second joint of the antennae is much wider in 
proportion to its length than that of O. kekele. 
Length about 2°5 mm, 
Hab. Hawau, Kilauea; found on Cyathodes.
