This is another yellow species that can be distinguished from luteola and perpallida by the brown facial and abdominal foveae. It differs from perpallida also in having the notch at apex of pygidial plate weak, the sculpture less dull, and the coloration deeper yellow.

Female.—Rather bright clear yellow, including the proboscis, but with the face below antennae, mandibles except reddish tips, and the labrum more pallid; face usually and the posterior surface of propodeum tinged with green. Antennae yellow, tinged with pale brown at base of the flagellar joints. Legs yellow, the four apical joints of hind tarsi blackish. Foveae of frons and second tergite pale brown. Tegulae pale testaceous, becoming more yellowish at base. Wings whitish hyaline, the nervures and margins of stigma pale yellow.
