P. zebrata is probably the most abundant, or, at least, the most easily collected species of the genus in the Rocky Mountain states. It has been recorded from numerous localities in New Mexico, Colorado, Nebraska, Montana, and Utah, and the form with yellow markings, now to be known as P. zebrata flavens, from Wyoming and Nevada. It collects pollen from species of Cleome, but has been re¨corded also from flowers of Solidago and Helianthus, which it visits presumably only for nectar. The type locality is Colorado, without a more definite location.
Cresson confused two distinct species in his description of zebrata, the nontypi-cal one (female of luteiceps Cockerell) having bright yellow markings, which accounts for the mention of yellow in the markings and the asserted extension of the face marks above level of antennae.
The typical form of sebrata with yellowish white markings has been examined from the fol¨lowing localities.óCOLORADO: Boulder, Boulder County, on Cleome (Cockerell) ; Boulder County, July 4, 1925 (C.
