Laphria flavicollis Say:

    face hairs erect on upper portion of upper face, yellow; female with a few black hairs to each side of and below the antennal bases; in both sexes central portion of upper face also with erect yellow hairs; lateral portions with procumbent yellow hairs, projecting over gibbosity to each side; hairs on gibbosity erect, in male yellow from about one-half distance above top of oral margin to top of gibbosity, in female,yellow from about one-fourth this distance; 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 black on top third, lower two-third entirely yellow

    hairs underneath the proboscis yellow

    palpal hairs yellow on first segment, black on second segment

    postpronotal lobes in male, entirely yellow haired; in female variable, ranging from entirely golden yellow to being covered with black hairs on anterior three fourths

    mesonotum in male evenly covered with long yellow hairs, about two-thirds of which are recumbent and the remaining third erect; these hairs completely obscure the ground color and increase slightly in length as one moves posteriorly to the calli, giving the vestiture of the thorax the look of neatly trimmed erect yellow pile; female similar, except that the hairs are more golden yellow, and perhaps three-fourths of them are recumbent, this proportion decreasing posteriorly, giving the vestiture of the thorax a silky golden-yellow aspect when viewed from a distance

    tuft of hairs in front of wings black

    tuft of hairs in front of haltere mostly to entirely yellow

    scutellar hairs disk covered with more-or-less recumbent, medium-length yellow hairs, margin with row of erect long yellow hairs

    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 in male, fore-tibiae yellow haired posteriorly on about lower two-thirds, mid-tibiae yellow haired posteriorly on about lower half; legs entirely black haired in female

    hind tibiae black haired

    hind femora weak line of scattered yellow hairs stretching dorsally from near base to about three fourths way to apex; a few scattered yellow hairs also present ventrally near base; "knee" or apex black haired
