Orgilus fictus

Structurally this species is extremely like cinctus, new species, but the temples are a little wider and the second tergite is relatively shorter and broader; in color it differs in lacking the yellow band on the abdomen and in the darker antennae.

FEMALE.—Length about 3.8 mm. Head hardly as wide as thorax and in dorsal view 0.75 as long as wide; face protruding, clearly narrower than eye height, granulose above, alutaceous laterally and below; anterior tentorial pits much below level of lower eye margins; clypeus strongly convex and finely punctate; malar space less than one-third as long as eye height, finely shagreened and rather mat; cheeks weakly shagreened below, smooth and shiny above; temples smooth and polished, not receding and 0.85 as wide as eyes; occiput carinately margined only at the sides; ocellocular line slightly shorter than postocellar line and less than twice as long as diameter of an ocellus; maxillary palpi as long as height of head; antennae 31-segmented in the holotype, even the shortest flagellar segments a little longer than broad.

Mesoscutum shiny, but the surface of the lobes faintly alutaceous and with some extremely shallow, indistinct punctures; notauli sharply impressed and foveolate; disc of scutellum rather large, strongly convex and faintly alutaceous; propodeum largely weakly shagreened on basal half, finely rugulose on posterior declivity; side of pronotum largely finely granulose or shagreened, somewhat rugulose in the impression; mesopleuron smooth and polished, the longitudinal furrow sinuate and foveolate; metapleuron largely granulose or shagreened and rather mat. Hind coxa finely shagreened and subopaque; hind femur just about four times as long as wide, finely granulose and rather dull; inner calcarium of hind tibia slightly more than half as long as metatarsus; claws simple. Stigma very narrow, slightly shorter than radial cell on wing margin; second abscissa of radius nearly on a line with intercubitus; stub of third abscissa of cubitus about as long as second abscissa; nervulus a little postfurcal; hind wing five times as long as wide; lower abscissa of basella much longer than nervellus, half as long as mediella and fully half as long as maximum width of hind wing.

Abdomen with first tergite about 1.4 times as long as wide at apex, finely granulose over most of its surface, with only a few weak rugulae laterally, the dorsal keels weak but distinct to well beyond the spiracles; second tergite about 0.7 as long as wide at base, almost parallel-sided, finely and confluently punctate each side of the middle, smooth and polished across base and medially, faintly alutaceous apically; third tergite largely smooth and shiny, with only a little weak shagreening laterally; second suture sharply impressed; fourth and following tergites smooth and polished; ovipositor sheath about as long as distance from base of scutellum to end of abdomen.

Black; mandibles yellow; palpi blackish; clypeus ferruginous anteriorly; antennae yellowish brown below toward bases, darker above, the scape darker than the basal part of the flagellum; legs, including all coxae, testaceous, the femora more or less darkened on the upper edges, also the hind femur on inner and outer sides of apical fourth, the hind tibia dark, a little lighter on the middle third, the tarsi darkened; tegulae and wing bases yellow; wings somewhat smoky; abdomen black, even the sternites rather piceous.

HOLOTYPE.—In the Museum of Comparative Zoology, Harvard University.

DISTRIBUTION.—Known only from the holotype female, which was taken by H. Levi in sweeping a dry field at West Springfield, Erie County, Pennsylvania, 5 June 1961.
