"(Female: length 5 lines — Black; the pubescence white; that on
the thorax above slightly tinged with yellow; the abdomen very
bright, smooth and shining. The clypeus strongly punctured; the
flagellum of the antennae fulvous beneath towards the apex. Thorax
shiny and punctured; wings hyaline and iridescent^ the nervures
fuse-ferruginous. Abdomen impunctate at the base and very finely
punctured towards the apex; the apical margin of each segment,
except the basal one, with a white pubescent fascia.

e: A little smaller than tlie female, of the same jet-black
colour, with similar white pubescence, and the same bright polished
abdomen; the latter is oblong-ovate in the male, and of conical shape

502 The University Science Bulletin

"(Female: length 5 lines — Black; the pubescence white; that on
the thorax above slightly tinged with yellow; the abdomen very
bright, smooth and shining. The clypeus strongly punctured; the
flagellum of the antennae fulvous beneath towards the apex. Thorax
shiny and punctured; wings hyaline and iridescent, the nervures
fuse-ferruginous. Abdomen impunctate at the base and very finely
punctured towards the apex; the apical margin of each segment,
except the basal one, with a white pubescent fascia.

"Male: A little smaller than the female, of the same jet-black
colour, with similar white pubescence, and the same bright polished
abdomen; the latter is oblong-ovate in the male, and of conical shape
in the female, the apex being pointed. Hab. East Florida. )"
