Pompilus (Hesperopompilus) orophilus Evans
Pompilus orophilus Evans, 1947, Ent. News, 58: 14-16 [Type: 2, New Mexico: Raton, 7000 feet, 12 Aug. 1946 (HEE) (MCZ, no. 27, 660)].
Pompilus {Hesperopompilus) orophilus Evans, 1948, Proc. Ent. Soc. Wash., 50: 148-149. — Evans, 1951, Trans. Amer. Ent. Soc, 77: 214-216.
Female. — Length 6.5-9 mm. Black; pubescence a brilliant deep blue or blue-green; fore wings moderately infuscated, darker along outer margin, somewhat violaceous; hind wings subhyaline except infuscated toward the apex. Head with unusually abundant dark setae; prothorax slightly hairy, but remainder of body smooth and devoid of setae except for a few weak ones on the abdomen toward the apex. Clypeus 2.3-2.4 X as wide as high, truncate below. Front very narrow, barely wider than the two eyes together, MID .50-.54 X TFD; UID subequal to or slightly less than LID. Ocelli in a rather large tri

angle on the narrow vertex, POL much greater than OOL (about 3:2 in most specimens). Third antennal segment from .92 to 1.05 X UID. Pronotum short, subarcuate or broadly, weakly angulate behind; postnotum nearly as long as metanotum; propodeum with the slope rather low and even, with a weak posterior declivity. Front basitarsus with three (rarely four) slender combspines, the apical one about as long as the second segment. Pulvillar comb of about nine weak, diverging setulae. Fore wing with the marginal cell short, nearly or fully twice its own length from wing tip; SMC2 usually broader than
high, but SMC3 higher than broad in most specimens, narrowed by about half above.
Male. — Length 5-7 mm. Black, except posterior margin of pronotum with a pale yellowish stripe, interrupted medially; pubescence strongly bluish or violaceous except silvery on much of the head and pronotum, posterior part of mesoscutum, sides of scutellum, metanotum, pleura, coxae, propodeum (where the pubescence is very coarse), and basal bands on the first three tergites; wings hyaline, with a fuscous marginal band. Clypeus 1.8 X as wide as high, rounded below. MID .58-.61 X TFD; UID considerably exceeding LID; POL considerably exceeding OOL. Third antennal segment about twice as long as thick, slightly shorter than fourth segment. Postnotum about one third the length of the metanotum. Venation similar to that of female. SGP very slender, gradually tapering to an apical point, its margins fringed with setae, the basal appendages strong. Genitalia with the parameres slender, slightly exceeding the digiti, the latter somewhat capitate and with a few apical setae but none on the disc; basal hooklets present; aedoeagus much exceeding the rather short parameres (see figs. 174 and 203 in Evans, 1951).
