Rhagio gracilis Johnson
1912. Leptis gracilis Johnson, Psyche, xix, p. 3.
Yellowish; abdomen slender, banded with black; legs long and slender ; eyes of male widely separated; anal cell closed and petiolate.
Male. — Length, 6 mm. Head: Eyes almost as widely separated as in female — about one and one-half times the width of the ocellar tubercle; above the antennae are two fairly well defined tubercles; front, ocellar tubercle, and face blackish, light gray pollinose; palpi, and proboscis yellowish, face on sides and palpi with sparse pale hairs; antennae yellowish, arista black.
Thorax: Mesonotum yellowish, the whole disc tinged more or less with brownish and with several fine more or less definite darker lines due chiefly to rows of fine black hairs; pleura pale yellowish, more or less light gray pollinose; black hairs somewhat longer and more numerous on sides of mesonotum, and on scutellum which is dirty yellow in color; halteres pale yellowish.
Abdomen: Slender, yellowish, each segment with a broad black basal band except first which has a black spot below scutellum; clothed with short pale hairs on the yellow parts, with black ones on the black bands, longer on lateral margin. Legs: Pale yellow; tarsi slightly infuscated, a black spot on underside at tip of trochanters.
Wings: Membrane hyaline; veins pale brownish; stigmal spot obsolete; anal cell closed before the margin, the petiole often one-half as long as the distance between the fork of Cu and the petiole.
Female. — Length, 6 mm. Like the male except as follows: Front slightly wider — about twice width of ocellar tubercle; frontal tubercles above antennae less prominent; first abdominal segment sometimes with a complete basal black band.

This interesting species should probably form the type of a new genus because of the widely separated eyes in the male. Although no such condition exists in any other known genus of the subfamily Rhagioninae I hesitate to erect a genus based on a character of the male alone. The closed and petiolate anal cell alone in both sexes would be striking enough to remove this species from the genus

Rhagio gracilis is a species of snipe flies in the family Rhagionidae.
