This is another pale-yellow species allied to wootonae and mentzeliae and distin�guishable by the characters in the preceding key. Only the male is known.

Male.�Uniformly pale sulphur yellow, including antennae and legs, and without dark mark�ings. Apex of mandibles bright red; facial foveae reddish brown. Foveal lines of tergite 2 con-colorous. Tegulae subhyaline and yellowish at base. Wings whitish hyaline; nervures, including subcosta, very pallid.

Head as broad as long, cheeks very broad but receding, rounded, unarmed, and widest opposite anterior end of upper third of eyes. Occiput deeply and broadly concave; concavity a little broader than space between summit of eyes. Ocelli behind a line tangent to posterior end of eyes; lateral pair definitely closer to occipital margin than to nearest eye. Facial f oveae punctif orm. Proboscis moderately long, apex of galeae in repose not reaching base of stipites. Mandibles long, tapering, acute, and reaching well beyond far margin of proboscidial fossa. Flanks of pronotum moderately impressed and posterior corners of disk rather prominent and rounded. Pterostigma about two-thirds as wide as first submarginal cell; part of marginal cell beyond it much shorter than part beneath. Head and thorax shining, with faint tessellation visible under high magnification. Pubescence sparse, erect, and short, although long and much denser on sternum and underside of front coxae. Tergite 7 obtusely rounded at apex; subgenital plate nearly as in vwidinotata, but a little more acute at apex. Genitalia much as in viridinotata except that parameral lobes are more slender and much less hairy. Length: nearly 3 mm.; anterior wing, 2.7 mm.

Eolotype male.�St. George, Washington Co., Utah, May 26, 1919 (collector not known), in collection of American Museum of Natural History.

Extracted from: Cockerell T.D.A, (1913). Description and Records of Bees. - XXVI.

Male. Length 3.5 mm - 4.0 mm Very close to P. gutierrezie, Ckll., differing as follows:- Upper level of yellow on front practically straight, except a small notch for the foveal spot on each side; cheeks with the lower three-fourths entirely yellow; pleura yellow, except its broad upper margin; abdomen much darker, with successively narrower yellow hands on a dark brown ground ; anterior and middle tibiae each with a brown stripe, and there may be a small brown mark at apex of middle femora.

Hab. Idyllwild, San Jacinto Mts., California, abundant at flowers of Adenostoma fasciculatum, July 14, 2012 (P.H. Timberlake, 1)

The plant is Rosaceous, but the bee is related to the species occurring on flowers of Composite.
