Female. — Length 13-23 mm. Black, except femora dark brown above; pubescence varying in color from silvery through golden to brownish-violaceous, tending to be most conspicuous and of a pale golden coloration on the front, basal parts of the antennae, sides of metanotum, and base and apex of propodeum; pleura and basal parts of legs with pale golden to silvery pubescence; abdomen with pale golden to silvery pubescence except for apical bands on Tl-4, where the pubescence is dark. Wings bright yellow, the hind wings tipped with fuscous, the fore wings a narrow apical fuscous band and two broader fuscous bands, one crossing the wing at the basal vein, the other at the second and third SMCs. Mandibles, labrum, and upper front with a few strong setae, the abdomen with numerous erect setae toward the apex, body otherwise smooth and without setae. Labrum strongly exserted, truncate or shallowly emarginate apically. Clypeus a transverse band about 2.8 X as wide as high, depressed on the extreme sides, the median portion very broadly subangulate at the margin, the midpoint rounded or weakly produced. Head about 1.2 X as wide as high; front narrow, MID .47-.52 X TFD; UID .75-.85 X MID, orbits diverging slightly below the middle. Ocelli rather large, POL and OOL subequal, or either may be slightly greater. Third antennal segment about 5 X as long as its apical width, equal to from 1.25 to 1.55 X UID; ninth antennal segment less than half the length of the third, but thicker, measuring about twice as long as thick. Pronotum subangulate behind, with a faint median impression. Propodeum with a faint median impression and some fairly strong transverse rugae, especially at the margin of the declivity; anterior part rather flat, in profile, the declivity strongly defined and oblique. Middle and hind tibiae with numerous spines in longitudinal rows, apically with a rim of spines which tend to be only slightly splayed-out and only slightly unequal in length. Fore wing with the marginal cell removed from the wing tip by only about .6 its own length; SMC2 rhomboidal, slightly wider than high, SMC3 wider than second, narrowed by a third to a half above (fig. 12). Abdomen rather strongly compressed apically.
Male. — Length 11-14 mm. Black, marked with whitish on the sides of the clypeus and lower front, the outer side of the front tibiae, the tibial spurs, the basal third of the first abdominal segment and a large spot on the apical tergite; antennal segments 3-7 strongly suffused with rufo-castaneous below; wings colored as in female. Pubescence largely pale, silvery to pale golden, the patterning much as in the female, the propodeum with much semierect silvery to pale golden pubescence on the posterior two-thirds. Labrum as in female; clypeus simple, broadly truncate apically, 2.2 X as wide as high. Head 1.24 X as wide as high; front narrow, MID roughly half TFD; UID very slightly less than LID; ocelli rather large, POL equal to or slightly exceeding OOL. First four antennal segments in a ratio of about 6:2:8:7, segment three

2.3 X as long as wide; segments four and beyond roundly produced below, 71 1 especially so, almost subangular. Postnotum angularly produced backward medially; propodeum with the slope very low and even; median line of propodeum impressed, but disc without rugae. Legs strongly spinose. Wing venation as in female. Abdomen slender at base, apical part strongly compressed, especially the SGP, which has the median line folded, the two sides pressed against one another; when flattened out on a slide, the sides of the SGP are seen to be angulate toward the base. Genitalia as described under the generic heading and as shown in fig. 61.
