side, the first bifid in front. Ovipositor rufous, partly black
towards the extremity ; above it are two long and rather
stout black setae, densely plumose beyond the middle, the
apical third of the cilia being white ; the extreme tip of the
setae is spatulate and whitish beneath. Wings smoky, the

Pimpla nigricornis, sp. n.
Long. corp. cum ovip. 15 millim. ; ovip. 3 millim. exp. al.
23 millim.
Female.— Yellow, antennae and ovipositor black; vertex
with a black band covering the ocelli, which is pointed in front
and on each side of the frpntal ocellus ; mesothorax with a
large oval black spot on each side, a triangular reddish patch
in front, the hinder angle of which is black, and a transverse
black patch in front of the raised scutellum ; abdomen yellow
on the first two segments and shading into light reddish beyond
; a large black spot on each side of segments 3-5 ; the
first segment has a slight impression on each side, the five
following ones have a deep groove before the extremity ; the
front of the body is nearly smooth, but the third segment of
the abdomen is sparingly, and segments 4-6 heavily, punctured.
Legs slightly suffused with reddish ; middle femora
slightly, and hind femora considerably, thickened ; hind legs
much longer than the others and hind tarsi clothed with a
blackish pubescence.
One specimen.
Allied to the Indian P. punctata, Fabr.

Ophion latipenne, sp. n.
Long. corp. 26 millim.; exp. al. 53 millim.; lat. al. ant. 9
millim.
Female.— Rufo-testaceous, slightly pubescent; occiput, antennae,
legs, and especially the sides of the face, slightly more
yellowish ; eyes slightly emarginate in front just above the
antennae, below the antennae they are nearly parallel, or very
slightly incurved. Antennae pubescent, about 50-jointed
joints three and four annular, joint five the longest, the remainder
cylindrical, hardly longer than broad in the middle,
and gradually tapering and lengthening towards the extremity,
the last conical; tips of mandibles black; ocelli very
large, filling up the space between the eyes on the vertex,
black, except extreme front of the frontal ocellus beneath, and
the outer sides of the two hinder ocelli. Thorax and abdomen
very finely and closely punctured ; mesothorax with two converging
lines slightly yellower than the ground-colour, but
only carinated at the lateral borders ; metathorax also with a
middle carina. Abdomen very large, raised, and somewhat
compressed laterally. Hind legs longer than the others ; all
the tibia armed with a pair of terminal spines. Wings rather
broad, yellowish hyaline, more strongly tinged with yellow at
the base and along the costal area of the hind wings, and
towards the tip a little smoky, especially on the hind wings.
Nervures rufous along the costa and towards the inner margin
; otherwise blackish. Anterior wings with three bullae_
one on the lower curve of the cell near its extremity, one on
the recurrent nervule, and the third on the cross-nervule
running upwards from the extremity of the internal nervule.
The Ophionidae of Africa are rather numerous, but very few
have yet been described.
