Laphria cinerea (Back):

    face hairs on upper and central portion of upper face erect, yellow; these grade into a few procumbent yellow hairs laterally, which project over the gibbosity to each side; hairs on gibbosity erect, yellow above about half distance from top of oral margin to top of gibbosity, rarely intermixed in male with one or two black hairs, and in female with three or four; in both sexes hairs on lower portion of gibbosity black: area framed on each side of the oral margin by the gibbosity dorsally, and the inner margin of the eye dorsolaterally, is bare

    beard entirely yellow

    hairs underneath the proboscis yellow

    palpal hairs on first segment yellow in male, black in female; on second segment black in both sexes

    postpronotal lobes with long black hairs

    mesonotum in female with long recumbent yellow hairs present fringing posterior margins of postpronotal lobes and in diffuse band preceding scutellum; these areas and rest of disk with additional similarly-sized, sparse, erect yellow hairs, except on notopleural and intra-alar areas, where they are black; ground color of shiny black everywhere visible through vestiture; male similar, except that erect hairs are much less numerous and/or fall off more easily, resulting in a dorsum that is mostly bare

    tuft of hairs in front of wings yellow

    tuft of hairs in front of haltere yellow

    scutellar hairs hairs on disk medium length, restricted to near base, black; apical portion of disk itself turgid and shiny black; hairs on scutellar margin long and black

    ground color of legs from a distance the ground color appears to be black, but when viewed with a dissecting microscope, from an angle the surface appears to be blue black, and when viewed directly, that is from right angles, with artificial light, it appears to be very dark reddish brown; the surface is also highly reflective and where yellow hairs are present on the tibiae, reflects these as light reddish brown

    fore- and mid-tibiae both with yellow hairs anteriorly, dorsally, and posteriorly

    hind tibiae yellow haired for slightly more than basal half on dorsal surface; black haired apically

    hind femora thick line of light yellow hairs stretching dorsally from near base to about three fourths way to apex; "knee" or apex with conspicuous light yellow hairs

    abdominal segments tergites 1-4 and mid portion of 5 covered dorsally with short black hairs, which let the shiny black ground color show through; tergite 2 additionally with slightly longer black hairs on anterior margin to each side of the middline, and tergite 1 with yet longer (but still short) black hairs across the entire anterior margin; on both tergites these grading into much longer black hairs laterally, which are continued on tergites 3-4; in male, sides of tergite 5 and entire surface of 6 of 7 with yellow hairs; female identical, except that hairs on seventh tergite are black
