Orgilus comptanae

This species is readily distinguished by its largely reddish-yellow color from the other species that belong in the group in which the head is very long and the face is unusually protuberant.

FEMALE.—Length around 4 mm. Head slightly narrower than thorax, higher than wide in front view and fourth-fifths as long as broad in dorsal view, deeply excavated behind; face protruding strongly, its straight-line width hardly equal to eye height, weakly punctate or shagreened medially; clypeus weakly separated from face, smooth, as long as malar space, which is slightly more than one-third as long as eye height; anterior tentorial pits a little below level of lower eye margins; cheeks smooth and shiny except at the extreme lower margins where they are a little alutaceous; temples and cheeks bulging slightly, the temples impunctate and about 0.75 as wide as eyes; ocellocular line about one and one-half times as long as diameter of an ocellus; antennae 31- or 32-segmented in the available specimens.

Thorax slender; mesoscutum shiny, not distinctly punctate; notauli sharply impressed, foveolate; scutellar sulcus very broad and deep; propodeum granulose or very finely rugulose and rather mat; side of pronotum largely rugulose but finely granulose anteriorly; mesopleuron smooth and polished, the longitudinal furrow finely foveolate; metapleuron coriaceous and somewhat dull. Hind coxa about two-thirds as long as hind femur, finely granulose or coriaceous and rather dull above and on outer side; hind femur less than 4.5 times as long as wide; longer calcarium of hind tibia more than half as long as metatarsus; tarsal claws simple. Stigma very nearly as long as radial cell on wing margin; second abscissa of radius on a line with intercubitus; stub of third abscissa of cubitus longer than second abscissa; nervulus a little postfurcal; hind wing about five times as long as wide; lower abscissa of basella a little more than half as long as mediella and more than half as long as maximum width of hind wing.

Abdomen a little longer than thorax; first tergite hardly one and one-half times as long as wide at apex, finely rugulose except basally where it is smooth; second tergite nearly as long as wide at base, almost entirely finely rugulose; third tergite confluently punctate on basal half or more, smooth along lateral margins and posteriorly; the remaining tergites smooth and shiny; second suture impressed but very fine; ovipositor sheath nearly as long as distance from base of scutellum to end of abdomen.

Reddish testaceous; scape black above; antennal flagellum darkened apically; palpi blackish, also metanotum, hind tibiae apically and all tarsi; wings a little infumated.

MALE.—Essentially like the female but the abdominal sculpture usually a little weaker, and sometimes the body more extensively darkened.

HOLOTYPE.—USNM 70152.

DISTRIBUTION.—The type-series consists of the following: Female holotype reared from Ancylis comptana Froelich at Lockport, New York, 16 July 1929, by D. M. Daniel; a male paratype, also from A. comptana, reared by J. J. Davis at Moorestown, New Jersey, in May 1924; 2 males, Bridgeville, Delaware, 1932, from A. comptana; 1 male from Moorestown, New Jersey, “ex A. comptana infested leaves of strawberry”; 1 female, Salisbury, Maryland, ex A. comptana; and field-collected specimens from localities in Quebec, New York, Pennsylvania, New Jersey, Maryland, Virginia, North Carolina, Illinois, Mississippi, Georgia, and Florida.
