FEMALE—Length 10 mm.; black, with yellow maculations; clypeus with a pair of lateral, subapical, rounded maculations, a pair of slightly larger, oblong maculations between clypeus and lower inner orbits; mandibles yellow at base; vertex with a pair of small and narrow maculations on each side; tegulae with a small antero-lateral maculation, a similar one at each extreme side of scutum, adjacent to tegula; a small maculation on each axilla, and posterior margin of scutellum narrowly yellow, this band interrupted medially; abdominal terga 1-4 with large, yellow maculations at each extreme side and a pair of narrow, transverse and rather short maculations near center, the inner and outer maculations on terga 2-4 narrowly connected; tergum 5 with a pair of larger, submedian, transverse maculations which are only slightly separated and a narrow band connecting these with the extreme lateral margin, but without the lateral yellow spot; face slightly longer than distance between eyes above; eyes very slightly convergent below; lateral ocelli considerably nearer eyes than to margin of vertex; cheeks somewhat narrower than eyes; clypeus slightly convex, apical margin somewhat thickened, very finely tuberculate on each side, median area nearly straight; mandibles with 7 or 8 fine and rather irregular teeth; vertex and cheeks not carinate; tegulae shining, with minute and slightly separated punctures; wings subhyaline, veins piceous; legs black in large part, tibiae with elongate, basal, yellow maculations on outer face, front and middle tarsi with dense, short, snowy white pubescence, this somewhat more elongate on posterior side; spurs testaceous; pubescence short, and thin in general, entirely pale, white and rather copious between antennae and ocelli, on lower portion of cheeks, on pleura and lateral faces of propodeum; ventral scopa white; punctures fine and close over entire head and thorax, very fine and densely crowded between antennae and ocelli and on vertex medially, somewhat more coarse and irregular on clypeus, more distinct, with very narrow but definite intervening lines on scutum and scutellum; abdominal terga somewhat shining, punctures quite close but distinct, deep and rather well separated and coarser on anterior portion of basal tergum, the slightly depressed apical rims on terga 1-5 somewhat more finely and closely punctate, tergum 6 about twice as broad as median length, broadly triangular, with a median angle and a small angle at each extreme side, margin between minutely crenulate.

MALE—Length 11-12 mm.; black, with yellow maculations; clypeus, outer face of mandibles, scape, lateral facial maculae terminating abruptly at level of antennae, and a pair of transverse, narrow bands on each side of vertex, yellow; anterior margin of scutum with a pair of small, yellow maculations on each side, near but not attaining the tubercies, and a very small one adjacent to tegulae; axillae with rather small maculations, and posterior margin of scutellum narrowly yellow, this band interrupted medially; abdominal terga 1-5 with four maculations across each disc, the lateral pair quite large, median pair smaller, the inner and outer maculation on 2-5 narrowly connected, 6 with a pair of submedian, more or less rounded maculations that are slightly separated medially; face considerably longer than distance between eyes above; eyes very slightly convergent below; lateral ocelli slightly nearer eyes than to margin of vertex; clypeus slightly convex, apical margin very slightly incurved across median third; labrum with a pair of small tubercles near base, entirely black; mandibles conspicuously 3-dentate, inner tooth about mid way between the apical and inner teeth, the teeth black in marked contrast to the yellow base; tegulae with a yellow, antero-lateral blotch, otherwise dark, surface very finely and quite closely punctate; wings subhyaline, veins more piceous; coxae, trochanters and femora entirely black, each front and mid tibia with a yellow stripe along outer face, hind tibiae with a small, basal, yellow spot, otherwise these joints black; tarsi yellow, becoming somewhat more brownish at tips, front and mid pair with dense, snowy white pubescence which forms a rather conspicuous but short posterior fringe, hind tarsi with a somewhat similar anterior fringe; tegulae yellowish; hind trochanters with a very small and inconspicuous posterior tubercle; pubescence rather strongly ochraceous above on head and thorax, becoming snowy white laterally and beneath, quite copious over most of face, on vertex medially, and on cheeks below, thin on thorax dorsally but quite dense on pleura and propodeum, short and inconspicuous over most of abdomen; punctures very fine and close over entire head and thorax, somewhat less conspicuous on maculated areas of face and clypeus, and to a considerable degree obscured by pubescence above antennae; scutum densely and finely rugoso-punctate, punctures somewhat more distinct but very close on scutellum and pleura; terga 1-5 of abdomen shining, punctures distinctly although not widely separated on the more basal areas of each disc, the broadly impressed, apical margins more finely and closely but quite regularly punctate, those on 6 close and fine, 7 with a distinct, median spine, and on each lateral angle a robust, sub- truncate projection, giving a tn-dentate appearance; extreme lateral angles of terguni 6 with a robust, slightly curved but rather short spine; abdominal sterna 1-5 exposed, more or less copiously pubescent, especially laterally, sterna 6-8 retracted, form as shown (fig. 3); genital armature as shown.

DISTRIBUTION—Mexico and Arizona, east to Illinois, Virginia and Florida, March to November in the more southern parts its range.
