basal half of the
wings flavo-hyaline, the apical half fuscous; the stigma yellow, with a
subhyaline macula beneath, and two other similar irregular-shaped spots.
The abdomen with two longitudinal carinae on the basal segment, and a
transverse curved impressed line on the other segments.

_Hab._ Key Island.

This species might at first sight be mistaken for a species of the genus
_Bracon_. The male only differs from the female in having the abdomen
black, with only the basal segment yellow; the wings are only very
slightly yellow at their base; it is also rather smaller.

3. PIMPLA PENETRANS. _P._ flavo-ferruginea; flagello fusco; alis
flavo-hyalinis, apice fuscis.

_Female._ Length 4-1/4 lines. Reddish yellow, smooth, and shining; the
face testaceous, with slight fuscous stains; the scape and two or three
of the basal joints of the flagellum yellow in front; the wings hyaline,
with a yellowish tinge; the nervures black, except the costal nervure,
which is ferruginous towards the base, the apex of the wings slightly
clouded; the posterior tibiae fuscous above. Abdomen: the segments with
slightly impressed oblique depressions, the ovipositor shorter than the
abdomen, and black.

The _Male_ only differs in having the abdomen rather more slender.

_Hab._ Aru.

4. PIMPLA FERRUGINEA. _P._ flavo-ferruginea; antennis supra fuscis; alis
hyalinis.

_Female._ Length 5-1/2 lines. Ferruginous, with the head and thorax
beneath yellow-testaceous; the coxae also are of the same colour; the
flagellum slightly fuscous above; the wings flavo-hyaline, the nervures
black; the two basal segments of the abdomen shining, the third and the
following segments subopake; the ovipositor as long as the abdomen.

_Hab._ Key Island.

5. PIMPLA PLAGIATA. _P._ flavo-rufa; antennis strigisque tribus
mesothoracis nigris; alis hyalinis, apice cellulae marginalis fusco
unimaculato.

_Female._ Length 5-1/2 lines. Yellow, the legs with ferruginous stains;
the antennae black, with the scape yellow in front; the head with a large
ovate black spot behind the ocelli. Thorax finely punctured on the disk
of metathorax, which has three longitudinal broad black stripes, a
narrow black line on the posterior margin of both the scutellum and
postscutellum; wings hyaline, the nervures black, with a dark fuscous
spot at the apex of the marginal cell. Abdomen reddish-yellow, with the
apical margins of the segments yellow; the ovipositor black, and shorter
