very 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 fasciae, 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 tegulae 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 tibiae
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. CRABRONIDAE.

Genus OXYBELUS, _Latr._

1. Oxybelus agilis, _Smith, Cat. Hym. Ins._ pt. iv. 387. 25.
