head, where its golden colour renders it more evident. Antennae 
pale, scape near the tip and extreme base of the following joints with 
a small dark spot. Clypeus, a line adjoining it on each side, and 
one surrounding each eye, yellow. Pronotum flavescent, the callosi- 
ties rather browner, the hind angles with a dark spot and sometimes 
a median one between these ; seutellum more or less brownish- 
suffused, dark only in the extreme front ; tegmina, with the corium 
and clavus, generally more sordid than the pronotum, but the former 
quite pale along the costal margin, at the apex of which is a dark 
spot ; membrane with a conspicuous large smoky-black apical median 
spot, and a round one near the corium. Owing to the transparency 
of the membrane, when the tegmina are closed two round spots are 
naturally seen, one belonging to each membrane, followed by a large 
apical wedge-shaped mark. Legs yellow, the hind femora generally 
feebly and sparsely spotted with fuscous. 
Rostrum short, reaching to the metasternum, the metapleura 
conspicuously emarginate behind, the upper angle acutely produced. 
Head dull, very minutely rugulose or subgranulate; pronotum 
shining, moderately closely punctured, the callosities, a narrow 
median line, and the extreme hind margin impunctate.

Nysius comitans, sp. Nov. 
General appearance and colour almost identical with that of NV. 
hiloensis, but it differs as follows: the head is reddish or brownish, 
sometimes infuscate in front and with a very distinct median longi- 
tudinal pale yellow line, which, however, does not form a percurrent 
stripe with the clypeus ; all the femora bear conspicuous black dots, 
the infuscate pattern of the membrane is generally much fainter, the 
meso- and metapleura are reddish or reddish-brown (in hiloensis they 
vary in colour but are partly or sometimes nearly wholly black). 
Metapleura conspicuously emarginate behind, as in hiloensis, but 
the rostrum is long and reaches well behind the posterior coxae ; 
sculpture and clothing as in N. hiloensis.

Nyswus delectulus, sp. nov. 
This name may be used for the extremely abundant insect called 
N. delectus by Kirkaldy. It is very like that species, but may easily 
be distinguished by red or pale second and third antennal joints, 
which are either all black above in delectus or at least widely dark at
