This Florida version of Tirepeolus lunatus  has much more red coloration than usual, but the other traits all seem congruent with T. lunatus. 

Among them:  this is a moderately large bee; the integument of the thorax is black, while that of the protonal lobes is red; the legs (including the coxae) are red; the two pale median bands on the scutum do not touch the pronotal collar; the basal and apical hairbands of T1 are not parallel to each other; the dark medial region on T1 is wider than the pale bands on either side of it; the pale band  on T2 is narrowly interrupted and T2 lacks pale swaths of hair laterally; the pale bands on T3 and T4 are uninterrupted; the outline of the apical margin of the pseudopygidial area is convex; S5 looks straight in profile; the sternum is darkly-colored, and there are patches of white hair on the apical lateral areas of S2-S4; there is a weak unpitted median line on the clyepus.   The bee's wings are dark.

​

The following parts of this bee are red:  the tegulae; the pronotal lobes; the lateral front edges of the scutum; the axillae; the apical edge of the clypeus; the bases of the mandibles; the labrum; the proboscis; and the lower antennae (the scapes, pedicels, F1 & the base of F2).  S1 is partly dark-red laterally.

There were many Melissodes bimaculatus in the area where this bee was feeding.
