yellow fascia on their
apical margins; beneath, the two basal segments entirely ferruginous.

_Hab._ Aru.

This species is closely allied to the _P. fastidiosus_ of Saussure, and,
notwithstanding the difference in colouring, may possibly, I think, be
an extreme variety of that species.

5. POLISTES ELEGANS. _P._ ferrugineus; capite thoraceque flavo variis;
segmentis abdominis flavo marginatis.

_Female._ Length 8 lines. Ferruginous; the clypeus, mandibles, cheeks,
and the face, as high as the middle of the emargination of the eyes,
yellow. Thorax: the margins of the prothorax, two longitudinal stripes
on the mesothorax, the scutellum, postscutellum, and sides of the
metathorax broadly, yellow; the legs beneath, the coxae and the sides of
the thorax spotted with yellow; the intermediate and posterior coxae
spotted with ferruginous or fusco-ferruginous; the metathorax finely
striated transversely; the wings hyaline with the nervures ferruginous.
Abdomen: the first and three following segments with yellow marginal
fasciae, that on the fourth usually more or less obliterated.

_Hab._ Aru; Key Island.

Gen. FOENUS, _Fabr._

1. FOENUS GRACILIS. _F._ niger, facie lateribusque thoracis argenteo
pilosis; pedibus anticis et intermediis pallide rufo-testaceis, tibiis
posticis basi tarsisque albis; abdomine subtus rufo-testaceo.

_Female._ Length 6 lines. Black; subopake; the face, sides of the thorax
and beneath with silvery pubescence; the mandibles, palpi, and scape in
front rufo-testaceous. Thorax: the anterior and intermediate legs
rufo-testaceous, the femora having a darker stain above; the posterior
legs black, with the base of the tibiae and the tarsi white. Abdomen
rufo-testaceous beneath; the ovipositor white at its apex.

_Hab._ Aru.

Gen. STENOPHASMUS.

Head globose; antennae longer than the body, and very slender and
setaceous; the prothorax forming a slender neck; the anterior wings with
one marginal and three submarginal cells; the femora slightly
incrassate, not denticulate; the tarsi 5-jointed. Abdomen petiolated,
the petiole as long as the abdomen; the ovipositor as long as the
petiole and abdomen united.

This genus is founded on the examination of a single individual, which
in general appearance exactly resembles the smaller species of the genus
_Megischus_; on examination, however, it will be found that it differs
from that genus in the neuration of the anterior wing
