gth 5 lines. Black; head and thorax rather finely
punctured; the face covered with short cinereous pubescence; the clypeus
naked and much produced, the anterior margin and the tips of the
mandibles ferruginous; the cheek with long whitish pubescence. Thorax:
the sides of the metathorax, the floccus on the posterior femora and the
postscutellum with whitish pubescence, the latter produced in the middle
into a blunt tooth; the legs fusco-ferruginous, with the anterior tibiae
and apical joints of the tarsi brighter; wings hyaline and iridescent.
Abdomen shining and punctured, the apical margins of the two basal
segments broadly depressed, and more finely and closely punctured than
the rest; the apical margins of the second, third, and fourth segments
pale testaceous; the apical margins of the two basal segments narrowly
fringed with white pubescence, usually more or less interrupted in the
middle.

_Male._ Resembles the female very closely, but has the face much more
pubescent; the antennae filiform and longer than the head and thorax; the
scutellum armed at its posterior lateral angles with an acute tooth; the
metathorax truncate and slightly concave, its base with short
longitudinal grooves, the lateral margins fringed with long pubescence.
