but sparser, pubescence, which becomes progressively sparser and less con- 
spicuous posteriorly; abdomen nearly bare, although the tergites bear 
some very sparse, short setae, and the venter a few much longer hairs, 
especially at apex. 
General color dark metallic green with a bronzy luster; the mesopleura, 
tegulae, the fovea at each corner of the scutum, the posterior margin of 
the basal tergite, and a connecting median longitudinal band on the same 
segment, which tapers forward, dark purple; a median longitudinal pur- 
plish band also usually present on the mesoscutum; rest of the first and 
the second tergite bright metallic green, the following tergites greenish 
with a purple luster, the venter darker or more or less blackish; facial 
prominence, lower part of the cheeks, sides of the notum between the 
scutellum and base of the wings and propodeum more or less brownish with 
a green luster, or occasionally in a few of the paratypes the whole head 
and notum are more or less brownish with a metallic luster, thus pro- 
ducing a marked bronzy effect; antennae black, the scape and _ pedicel 
paler except on the ventral margin of the former (in slide mounts appear- 
ing distinctly brown), the dorsal expansion of both seape and pedicel with 
a bright green luster; mandibles brown; legs brownish yellow, all the 
coxae, the apex of middle tibiae, and the middle tarsi, except apical joint, 
paler yellow, all the femora on apical half and the tibiae on basal half 
infuscated and somewhat metallic greenish.

Male. Head hardly wider than long, the cheeks somewhat converging 
toward the broadly rounded oral margin; eyes of medium size, about a 
fourth longer than wide, broadly rounded anteriorly; frontovertex about 
as long as wide, and widening both in front and behind on account of the 
curvature of the eye-margins; ocelli large, arranged in a _ right-angled 
triangle, the anterior ocellus just behind the center of the frontovertex, 
the posterior pair almost touching the occipital margin and placed a little 
more than their own diameter from the eyes; cheeks as long as the width 
of the eyes; face coneave, the antennal prominnee not much elevated, 
somewhat longer than wide, and just above the antennal sockets changing 
into a very narrow rounded carina-like ridge, which ascends medially to 
the angulation between the face and frons; on each side of this ridge lie 
the shallow serobes, which are parallel in the upper third of their course 
and diverge below toward the antennal sockets. 
Frontovertex subrugulosely, transversely reticulate and with numerous 
fine scattered pin-punctures; face much smoother, being finely scaly-reticu- 
late, the scrobes smooth and polished; cheeks exterior to the genal suture 
longitudinally reticulate; mesonotum finely, transversely reticulate and with 
very fine punctures; the scutum subrugulose, but not so rough as the
