Male.--(See figure 15 for genitalia.) Length 16 mm. Head: clypeal margin extending downwards and somewhat inwards from the eyes for a short distance, bending and extending slightly more inwards for an equal distance, then rounding smoothly and running slightly upwards to center, forming a broad bat rather shallow central emargination; clypeus with very heavy white pubescence, black pilosity not very heavy; frontal suture distinct to anterior ocellus; a deep well-marked frontal depression, with many tiny punctures laterally, surface granulate near frontal suture; frons with a good many large somewhat elongated punctures, and a very great many tiny punctures; pilosity of head not heavy, black except on cheeks where some hairs have white tips. Thorax: collar broadly rounded; mesopleuron with large punctures well-spaced, and with a great many tiny punctures from which conspicuous white sericeous hairs arise, giving a marked sericeous appearance to mesopleuron; mesopleuron glossy, not reticulated; metapleuron with many shallow large and small punctures, some low ridges, and a glossy, somewhat wavy surface; propodeal side with rather weak ridges, front part with large punctures making the ridges less obvious; a weak sericeous patch beside petiole attachment; metanotal flange quite large, the edge tending to roll downwards slightly; prothorax and mesonotum with black pilosity, rest of thorax with mostly white pilosity, though with a few hairs black and some black at bases and white at tips. Petiole: slender and nearly straight. Abdomen: first segment black at base, rest of first, all of second and third, and half of fourth segments red, rest of abdomen dark blue.


Female--Length 17 mm. Head: clypeus strongly bulging, surface reticulate, large punctures variable in size; tipper edge of clypeus distinct, curved. Thorax: surface of meso- and metapleura glossy, not reticulate, with many tiny punctures between large ones; a thin spot of brownish sericeous hairs beside petiole attachment, an area on posterior part of metapleuron, a thin band in front of metapleural-propodeal suture, and an area in front of meso-metapleural suture extending somewhat over mesopleuron; pilosity of thorax entirely black. Petiole: only slightly longer than hind coxa, but rather slender. Abdomen: first, second, third, and lateral and ventral parts of fourth segments red, rest of abdomen dark blue.

Variations.--Metapleuron sometimes wavy and with weak ridges over the entire surface; propodeal side sometimes definitely ridged everywhere. Male: length 10-16 mm.; rarely clypeal margin extending downwards and inwards a short distance, then bending sharply to run transversely to center without further bending or any central emargination; rarely frontal depression shallow and not well-marked; rarely clypeus with a few white pilose hairs; pilosity of cheeks rarely entirely white; all pilose hairs of thorax except on prothorax may be white; sometimes propodeum with a definite sericeous patch on each side of petiole attachment, and meso- and meta pleura occasionally rather sericeous; only very rarely that mesopleuron is not markedly sericeous, these eases apparently due mainly to rubbing; amount of red on abdomen occasionally reduced to second segment only; sometimes abdomen red and bright blue. Female: length 14-18 mm.; rarely mesopleuron without tiny punctures; fine brownish sericeous hairs sometimes conspicuous over entire meso- and metapleura and propodeal side; pilosity of posterior part of mesopleuron, and all of metapleuron and propodeum, white in several specimens; in several specimens abdomen entirely red.

This species is most closely related to robusta and mickeli. In the male sericea: frontal depression deep and well-marked, almost circular except where ocellus projects into it; mesopleuron with large punctures well-spaced, very many shallow tiny punctures from which white sericeous hairs arise, these hairs abundant up to rectangle; surface of mesopleuron glossy; metapleuron rather crinkly, ridges poorly marked and tiny punctures shallow, surface glossy and with white sericeous hairs; pilosity of thorax mostly white. In the male robusta: frontal depression moderately deep, elongated anteriorly, the limits not well-defined usually only a few, and sometimes no sericeous hairs on meso- and metapleura; large punctures of mesopleuron numerous, surface of plate distinctly reticulate, therefore not as glossy as in sericea; metapleuron more or less distinctly ridged, surface reticulate; pilosity of thorax mostly white. In the female sericea: mesopleuron with a great many tiny punctures and a glossy surface, short brownish sericeous hairs more or less conspicuous. In robusta and also mickeli: mesopleuron with very few tiny punctures, surface reticulate and not highly glossy; brownish sericeous hairs occasionally present but not usually as conspicuous as in sericea. The notes under mickeli give the best characters for separating mickeli from robusta, and those notes on mickeli can be compared with these notes on sericea for separating mickeli from sericea.
