Orgilus monticola

This is closely similar to mundus, new species, but it may be distinguished by the differences noted in the description of mundus.

FEMALE.—Length about 4 mm. Head slightly wider than thorax, in front view not, or barely, wider than high, in dorsal view about 1.5 times as broad as long and rather strongly excavated behind; face slightly (1.1 times) broader than eye height, shiny, indefinitely sculptured laterally, smooth down the middle; malar space longer than clypeus and half as long as eye height; cheeks strongly convex, smooth and polished except near lower and posterior margins where they are finely shagreened; temples not distinctly receding, in side view bulging a little opposite middle of eyes and at this point very nearly as wide as eyes; carinate margin of occiput rather narrowly interrupted medially; ocellocular line more than twice as long as diameter of an ocellus; antennae of holotype 31-segmented, even the shortest flagellar segments distinctly a little longer than broad.

Thorax slender; mesoscutum smooth and shiny, weakly punctate on the middle lobe; notauli sharply impressed and strongly foveolate, a narrow triangular rugulose punctate area at their junction; propodeum irregularly rugulose, with a polished area each side of the middle at base, the anteriorly open median apical area poorly defined, the stubs of the longitudinal carinae that arise from the posterior margin being weak, an area each side of the median apical area smooth and shiny, apical margin of propodeum strongly reflexed; side of pronotum rugulose, more or less granulose anteriorly; mesopleuron smooth, the longitudinal furrow foveolate; metapleuron smooth on basal half or more, rugulose apically. Hind coxa finely granularly rugulose above at base, very shiny and nearly smooth on outer side with only very shallow punctures; hind femur twice as long as hind coxa and about five times as long as broad; longer calcarium of hind tibia a little more than half as long as metatarsus; tarsal claws simple. Radial cell on wing margin about as long as stigma; second abscissa of radius on a line with intercubitus; stub of third abscissa of cubitus as long as second abscissa; nervulus postfurcal by one-third its length; hind wing only slightly more than four times as long as wide; lower abscissa of basella a little longer than nervellus but less than half as long as mediella and much less than half as long as maximum width of hind wing.

Abdomen as long as head and thorax combined; first tergite about 1.3 times as long as wide at apex, largely longitudinally striate, smooth medially toward base and with 2 very weak, convergent dorsal keels on basal half; second tergite virtually parallel-sided, as long as broad at base, largely faintly aciculate, rather transversely so toward base and longitudinally so posteriorly; third and following tergites smooth and polished; ovipositor sheath longer than head, thorax and abdomen combined.

Black; palpi blackish; scape entirely black, flagellum more or less yellowish brown toward base, black apically; legs brownish yellow; hind coxae black except at apices; fore- and middle femora somewhat darkened basally above, the anterior pair more extensively so than the middle pair; hind femora blackish on inner surface; tarsi a little dusky; tegulae and wing bases black; wings very weakly clouded.

MALES.—Unknown.

HOLOTYPE.—USNM 70183.

DISTRIBUTION.—Known only from the holotype female, which was collected at Bear Valley, Idaho, 6400 feet, 11 July 1926, by R. W. Haegele.
