ints towards their base; the
legs thickly spinose and pubescent; the calcaria simple. Abdomen with
scattered fine punctures; the apical segment densely clothed with black
pubescence; beneath, with strong scattered punctures.

_Male._ Rather smaller than the female, much more closely punctured, and
not so shining and smooth; the face with a transverse arched carina
above the insertion of the antennae, which enters the emargination of the
eyes; the clypeus strongly punctured; in other respects resembling the
female.

_Hab._ Aru.

This species belongs to Guerin's division Liacos, of which _S.
dimidiata_ is the type; the third discoidal cell is petiolated, the
petiole entering the second submarginal about the middle.

4. SCOLIA INSULARIS. _S._ nitida nigra; abdomine prismatico, alis
obscure fuscis cupreo submicantibus.

_Male._ Length 7-9 lines. Shining black; head punctured, the vertex most
finely and distinctly so. Thorax punctured, the disk of the mesothorax
impunctate, the punctures wide apart on the scutellum and metathorax;
the wings dark brown with a coppery iridescence, which has a remarkable
dimness as if breathed upon. The basal segment of the abdomen strongly
and closely punctured; the following segments more finely and distantly
punctured, particularly the second and third segments.

_Hab._ Key Island.

5. SCOLIA QUADRICEPS. _S._ nitida nigra; foeminae capite magno
subquadrato, alis fuscis cupreo iridescentibus.

_Female._ Length 6-8 lines. Black and shining; head subquadrate, smooth
and shining, as wide as the thorax, with a few punctures at the sides of
the face and between the antennae. Thorax finely punctured, with the disk
of the mesothorax impunctate; wings dark brown with a rich coppery
iridescence. Abdomen with a fine prismatic lustre, closely and strongly
punctured towards the apex and at the extreme base, the second segment
and the middle of the third with only a few very fine scattered
punctures.

_Hab._ Aru.

This species also belongs to the division Liacos; the petiolated cell is
small and oblong-quadrate; the male exactly resembles the female, except
that its head is smaller and narrower than the thorax; the abdomen is
rather more strongly punctured.

Gen. POMPILUS, _Fabr._

1. POMPILUS DUBIUS. _P._ niger, pilis mutabili-sericeis tectus; alis
subhyalinis, apice nebuloso.

_Female._ Length 4-1/4 lines. Black and covered with a thin changeable
silvery pile, which is most dense on th
