Orgilus lissus

This species is very similar to fulgens, new species, but the face, propodeum, and first tergite of the abdomen are much smoother.

FEMALE.—Length 4.3 mm. Head a little narrower than thorax, deeply excavated behind, in dorsal view about 0.9 as long as wide; face narrower than eye height (in ratio of 65:75), smooth and shiny with only a few weak punctures; clypeus slightly longer than malar space, not sharply separated from face medially, sparsely punctate; malar space one-third as long as eye height; cheeks and temples smooth and polished, the latter very nearly as wide as eyes and flat, not at all receding; vertex polished; occiput carinately margined only at the sides; ocellocular line a little less than twice as long as diameter of an ocellus; antennae of holotype incomplete.

Thorax much higher than wide; mesoscutum very smooth and shiny, the lobes impunctate; notauli very fine, weakly and incompletely foveolate; disc of scutellum small, convex, polished; basal third of propodeum completely smooth and shiny, the remainder with only a little weak rugulosity; side of pronotum largely rugulose; mesopleuron smooth and polished, the longitudinal furrow shallow and finely foveolate; metapleuron smooth and polished, rugulose only very narrowly at the lower posterior margin. Hind coxa smooth and shiny; hind femur barely twice as long as hind coxa and slightly less than four times as long as wide; inner calcarium of hind tibia half as long as metatarsus; tarsal claws simple. Radial cell on wing margin barely longer than stigma; second abscissa of radius on a line with intercubitus; nervulus barely postfurcal; hind wing 4.5 times as long as wide; lower abscissa of basella half as long as mediella.

Abdomen about as long as head and thorax combined; first tergite almost entirely smooth, only a little faint sculpture near the middle laterally; second tergite about 1.25 times as broad at base as long, finely rugulose punctate on basal third, otherwise smooth and shiny; third tergite virtually smooth, with only a little very weak punctation near base; ovipositor sheath a little shorter than thorax and abdomen combined.

Black; clypeus black; mandibles ferruginous; palpi black; antennal scape black, the flagellum brown below toward base; blackish apically; legs testaceous, the apices of the hind femora and of the hind tibiae and all the tarsi more or less darkened; tegulae black, wing bases yellowish brown; wings subhyaline; abdomen entirely black above and below.

MALE.—Unknown.

HOLOTYPE.—USNM 70175.

DISTRIBUTION.—Known only from the holotype female, which was taken at Sierraville, Sierra County, California, 14 July 1958, by R. M. Bohart.
