Head and thorax closely, strongly punctured ; the head more closely 
and not quite so strongly punctured as the thorax, except the clypeus 
which is more strongly and less closely punctured than the front ; it is 
as wide as long and has the apex transverse ; base of thorax transverse, 
margined ; apex of post-scutellum smooth, gradually bluntly narrowed 
towards the centre at the apex ; sides of meta thorax broadly rounded, 
the central furrow wide, slightly widened towards the apex, where its 
sides are oblique and striated ; it is covered with white pubescence ; 
abdominal petiole as long as the head and thorax united, slightly narrowed 
at the base ; the base of the second segment is distinctly narrowed ; the 
second segment is bell-shaped and is longer than it is wide at the apex ; 
hinder ocelli separated from each other by about the same distance as 
they are from the eyes ; palpi reddish and bearing a few stiff longish hairs. 
Eumenes spilocera, sp. n. 
Black ; the antennae, except the scape above and the greater part of 
the sixth to ninth joints, the mandibles, clypeus, the greater part of the 
space between the antennae, a broad curved line in the centre of the 
eye incision, the prothorax, tegulae except near the base, scutellum 
except at the apex, post-scutellum except at the base, metanotum except 
in the centre, the black central line dilated at the base, a large mark on 
the mesopleurae, the part of it below the furrow smaller than that above 
it and narrowed obliquely below a longish mark below the hind wings, 
the first abdominal segment except for an irregular line on the apical 
fourth above, the line obliquely narrowed at the base and apex, the 
basal part longer than the apical, a large mark on the sides of the basal 
half of the second, the apical third except irregularly in the centre, and 
the sides and apex of the ventral surface broadly, irregularly, red ; wings 
hyaline, fulvous behind the costa ; the radial cellule fuscous- violaceous ; 
the nervures black ; the stigma testaceous ; the second abscissa of radius 
one- third of the length of the third, which is roundly curved towards the 
costa. Female.

There is a broad yellow line on the inner eye orbits extending from 
the top of the clypeus to near the end of the lower part of the incision ; 
an irregular line on the face below the antennae ; a narrow line on the 
upper half of the outer orbits, not reaching to the top, and the keels at the 
sides of the scutellum, yellow ; clypeus clearly longer than wide, the apex 
broad, transverse ; it is sparsely, weakly punctured ; front and vertex 
closely, but not very strongly punctured ; a smooth space at the oeelli, 
the hinder of which are separated from each other by a slightly greater 
distance than they are from the eyes ; thorax densely punctured and 
covered, especially above, with white pubescence ; metanotal furrow 
hardly widened towards the apex, the sides broadly rounded ; abdominal 
petiole clearly longer than the head and thorax united ; apex of post- 
^cutellrum bluntly, roundly narrowed,
