Gen. MYGNIMIA, Smith.
1. Mygnimia iridipennis, Smith, Journ. Proc. Linn. Soc. ii. p. 98.
Hab. Celebes, Borneo.
This insect, a female, is 5 lines larger than M. iridipennis; but I can
point out no other distinction beyond a slight difference in the colour of
the wings: the specimen from Borneo has a metallic bluish-green
iridescence, the Celebes insect has a violet iridescence; notwithstanding
which I am inclined to regard them as one species.
2. MYGNIMIA FUMIPENNIS. M. aurantiaco-rubra, alis obscure
fuscis.
Female. Length 9 lines. Orange-red; the anterior margin of the clypeus
entire; the labrum produced, its anterior margin widely emarginate;
eyes large, black and ovate. Thorax: the posterior margin of the
prothorax rounded; the mesothorax with a longitudinal fuscous stripe
on each side, widest anteriorly; the metathorax truncate; above,
transversely striate; the tibiæ and tarsi spinose; wings dark fuscous,
with a pale semitransparent macula at the base of the second discoidal
cell and a dark fuscous macula beyond; the insect entirely covered with
a fine orange-red downy pile.
Hab. Celebes.
Fam. SPHEGIDÆ.

vestita; alis fuscis cupreo iridescentibus.
Male. Length 10-1/2 lines. Black; the head and thorax opake. Abdomen
shining blue-black. The face with silvery pile on each side of the
clypeus, and sprinkled with erect black hairs. Thorax: the posterior
margin of the prothorax with a line of silvery pubescence; the

metathorax with a short light-brown pubescence at the apex, and thinly
clothed with black hairs; wings dark brown, with a brilliant violet
iridescence. Abdomen blue-black, smooth and shining.
Hab. Celebes.
2. AMMOPHILA INSOLATA. A. nigra, scapo mandibulis, pedibus,
abdominisque segmentis primo et secundo ferrugineis; alis subhyalinis.
Female. Length 8-1/2 lines. Black; the scape, the base of the flagellum
beneath, the anterior margin of the clypeus and the mandibles
ferruginous; the latter black at their apex. Thorax: the prothorax smooth
and shining; the meso- and metathorax above transversely striated, the
scutellum longitudinally so; the legs ferruginous, with their coxæ black;
a spot of silvery-white pubescence on each side of the metathorax at its
base, and two at its apex close to the insertion of the petiole; the wings
fulvo-hyaline with the nervures ferruginous. Abdomen: the petiole and
the following segment red, the base of the third also slightly red; the
three apical segments obscurely blue, with a thin glittering pile.
The male differs in having the legs black, their articulations only being
ferruginous; the head entirely black with the face densely covered with
silvery-white pile. The thorax is sculptured as in the other sex; the
petiole more elongate and slender, the basal joint black, the second and
the first segment ferruginous beneath; the rest of the abdomen blue.
