OF WASHINGTON. 81 pointed, hind margin flattened and slightly concave before tip, basal half of costal area rather narrow; hyaline, with pale brown markings, those in apical portion of wing more or less coalescent and forming on each gra date series an oblique streak; pterostigma indistinct, pale; an indistinct pale line bisects the costal space longitudinally through the bases of inter costal forks; veins pale, with numerous brown interruptions, those on radius and cubitus most pronounced ; each brown spot on the longitudi nal veins between radius and hind margin gives off an oblique pale brown mark each side, thus forming several series of V-shaped markings, the angle of the V's pointing inward; gradate veins almost wholly brown ; hind margin of wing brown, interrupted with pale spots; posterior fork of median vein strongly bent toward the cubitus, thus making the inner veinlet connecting it with the cubitus much shorter than the outer ; radio-median cross vein situated at least as far before the forking of the median as the former is long and joining radius much before origin of first sector ; three radial sectors, anterior branch of the third forked before the inner gradate series and before the subpterostigmal radial cross vein, posterior branch simple; five gradate veins in inner series, the last beyond the next to the last, seven or eight in outer series (seven in left wing, eight in right wing, in the type specimen). Posterior wings hyaline, unmarked; the veins pale, tinged with reddish brown, some of the gradate veins darker; the first fork of radial sector plainly before forking of median.
