in front, the mandibles, and palpi ferruginous. Thorax: the sides
and beneath with a thin silvery-white pile; the legs ferruginous with the
coxæ black, the posterior pair red beneath; the thorax closely punctured,
the metathorax transversely striated; wings fulvo-hyaline, the nervures
pale-testaceous. Abdomen shining, very closely and delicately
punctured; thinly covered with a fine white silky pile, which is very
bright on the margins of the segments, which are slightly rufo-piceous.
The male closely resembles the female, and is similarly sculptured and
coloured.
Hab. Celebes.
7. LARRADA FESTINANS. L. nigra; facie abdominisque marginibus
segmentorum argentato-pilosis.
Female. Length 3 lines. Black; the face and cheeks thinly covered with
silvery pile. Thorax: the disk very closely punctured, the metathorax
rugose; the sides and the legs with a fine glittering sericeous pile, the
wings subhyaline, their apical margins fuscous, the nervures fuscous.
Abdomen smooth and sinning, covered with a thin silky pile, the apical
margins with bright silvery fasciæ, only observable in certain lights.
The male closely resembles the female, but has the face more silvery.
Hab. Celebes.
Genus MORPHOTA, Smith.
1. MORPHOTA FORMOSA. M. capite thoraceque nigris; abdomine
rufo, apice nigro, pilis argentatis ornato.
Female. Length 5 lines. Black, with the two basal segments of the

abdomen red; covered with a brilliant changeable silvery pile, most
dense on the face, cheeks, sides of the metathorax, and on the apical
margins of the abdominal segments. The mandibles ferruginous, with
their apex piceous. The vertex smooth, and having three distinct ocelli;
the head more produced behind the eyes than in Larrada. Thorax: the
prothorax subtuberculate at the sides; wings subhyaline and iridescent,
the nervures fuscous, the tegulæ pale testaceous behind. The apical
margin of the first segment of the abdomen rufo-fuscous.
Hab. Celebes.
The insects belonging to the genus Morphota differ from those of
Larrada in having three distinct ocelli, the vertex without any
depressions, and the head much less compressed than in Larrada; the
recurrent nervures are received nearer to the base and apex of the
second submarginal cell; the species have, in fact, a distinct habit, and
do not assimilate with the species of Larrada.
Genus TACHYTES, Panz.
1. TACHYTES MOROSUS. T. niger, scutello abdomineque nitidis,
facie argenteo-pilosa; marginibus lateralibus abdominis segmentorum
argentatis.
Female. Length 4-1/2 lines. Black; the face covered with silvery pile;
the thorax finely and very closely punctured; the metathorax opake and
finely rugose, thinly covered with cinereous pubescence; the anterior
tarsi ciliated on the exterior, and the intermediate and posterior tibiæ
with a few dispersed spines; wings fusco-hyaline and iridescent, the
nervures fusco-ferruginous, the costal nervure black. Abdomen smooth
and shining; the apical margins of the intermediate segments slightly
depressed, with the sides sericeous.
Fam. CRABRONIDÆ.
Genus OXYBELUS, Latr.
1. Oxybelus agilis, Smith, Cat. Hym. Ins. pt. iv. 387. 25.

Hab. India, Celebes.
GENUS CRABRO, Latr.
1. CRABRO (RHOPALUM) AGILIS. C. obscuro-nigra, clypeo
argentato, capite, thorace abdomineque flavo variis.
Female. Length 4 lines. Black, opake; head larger than the thorax,
quadrate; the ocelli in a curve on the vertex; the clypeus and lower
portion of the cheeks with silvery pile; the scape, two basal joints of the
flagellum, the palpi, and the mandibles, yellow; the latter rufo-piceous
at their apex. The margin of the prothorax, the tubercles, the scutellum,
the tibiæ and tarsi, the anterior femora and the intermediate pair at their
apex yellow; the anterior femora black above; the wings subhyaline and
iridescent, the nervures testaceous. Abdomen: with an elongate clavate
petiole; the first segment with an oblique yellow macula on each side,
the third with a large lateral macula at its base, and the following
segments entirely yellow.
Hab. Celebes.
This species closely resembles the C. Westermanni of Dahlbome, from
the Cape of Good Hope.
GENUS CERCERIS, Latr.
1. Cerceris instabilis, Smith, Cat. Hym. Ins. pt. iv. 452. 74.
Hab. India, China, Celebes.
2. Cerceris unifasciata, Smith, Cat. Hym. Ins. pt. iv. 456. 84.

hyalinis; pedibus variegatis; abdomine flavo maculato.
Male. Length 6 lines. Black; a line down the inner orbits of the eyes,
continued along the lower margins of the face, and uniting with the
clypeus, which as well as a line above it between the antennæ are
yellow; a spot on the scape in front, and the mandibles, yellow; the
latter rufo-piceous at their apex. Thorax: a spot on each side of the
prothorax, a minute one on the tegulæ; the postscutellum, the
intermediate and posterior coxæ and trochanters, the anterior tibiæ
behind, the femora beneath, and the intermediate and posterior tibiæ
yellow; the femora reddish above and at their articulations; the
posterior femora and tibiæ black, with the tarsi rufo-testaceous; the
anterior wings and the apex of the
